How Long to Let Your Memory Foam Mattress Expand?

The general rule is to give your new memory foam mattress 48 hours to expand and inflate to its proper size.

The real answer is not that simple. Every memory foam mattress has its unique requirements.

The following chart shows what each manufacturer recommends. Below that we go over where the 48 hours comes from and if you can immediately sleep on your new mattress.

Mattress Expansion Times For Each Manufacturer

ManufacturerTime
amerisleepCan lay on it right away but could take 8 hours for the corners to expand fully and you should wait 2 hours before putting sheets on.
BEDBOSSShould decompress in 24 hours, but let it sit for 2 hours before moving it to the bedroom.
Bedinabox“It expands in about 3 minutes” is what I got when I emailed them. This seems too fast; I would still give it a few hours to be on the safe side.
CasperCan expand and be ready to sleep on in a few minutes but keep in mind that some will take longer.
Classic BrandsAllow 24 to 72 hours for the mattress to regain its full shape. If the mattress gets to its full height, it’s ready to use.
Dreamfoam Bedding6 to 7 hours from opening.
HelixGive it 2 hours to regain its shape, and you’re done.
LaylaWill take its full shape within minutes, and you can sleep on it right away. If you’re sensitive to smell give it a few hours to air out.
LeesaMay take up to an hour to expand but give it 24 hours to fully expand and be at its best
LinenspaUp to 48 hours but they do say you can jump on it as soon as you like. If anything they say your body heat can help speed up the expansion process.
LUCIDUp to 48 hours, but if it’s fully expanded after 24 hours you can go ahead and sleep on it.
LullWill do most of the expanding in 2 to 5 hours and fully expand in 24 to 48 hours.
MLILYShould be ready in 24 hours. Walking on it while it’s on the floor can help speed up the process.
NectarBetween 24 to 72 hours to expand.
Nest BeddingYou can sleep on it right when you open it, but it can take up to 24 to 48 hours for it to fully expand.
Olee Sleeplet it expand up to 72 hours
PuffyAllow it to expand and breathe for a few hours before putting bedding on it.
Purest Of AmericaAllow 24 to 72 hours to fully recover.
Signature SleepWait at least 48 hours.
Tuft & NeedleOnly takes several hours to reach the proper specifications, but in some cases, it may take up to 5 days.
TuloAllow it to sit for an hour before using it.
Zinus48 to 72 hours to fully decompress. Zinus recommends you sleep on the mattress during this time as it helps to full up the mattress. If after a week it hasn’t expanded, please contact them.

Don’t see your mattress? Go ahead and give it a couple of hours to expand, but let me explain why.

Can You Sleep on a New Memory Foam Mattress Straight Away?

The reason why you wait 24 hours, 48 hours or 72 hours is an old saying that people keep repeating.

As shown from the chart a significant number of manufacturers report shorter times and a good bit suggest sleeping on the mattress the first night. The reason is for your constant movements, and body heat loosens the foam. The more lose the foam, the better it expands.

Where The 48 Hour Memory Foam Expansion Time Came From

The first generation of memory foam mattresses is where this wait time wives tale came from. More time was needed for older memory foam mattresses to air out there odors.

The mattresses today don’t smell as bad; I would still recommend letting them air out for a few hours to absorb the smells of its surroundings. I know it sounds odd, but it’s well worth doing.

What if my mattress says to wait a few hours? – Well, it’s better to play it safe than sorry. The people that best understand your mattress are the ones who made it.

What If Your Memory Foam Mattress Is Not Inflating?

No need to worry if your memory foam mattress is not expanding; here is what you do.

Get the mattress flat as possible on the floor. Wearing clean socks walk on the mattress. The constant moving around combined with your body heat expands the mattress. I like to think of it as a mattress massage.

After massaging the mattress place it back on the bed frame and sleep for a few nights.

Keep in mind:New mattresses are like new shoes; they need to be broken in. Over the years you have gotten used to your old mattress, so the new one is going to feel different. We tend to forget this because we only buy mattresses every decade or so.

What To Do After Your Memory Foam Mattress Has Expanded?

I mean, you spent all this money you probably want it to last as long as possible?

If you want your mattress to last, you need a mattress protector.

Your mattress is a giant sponge, and it will soak up all the sweat, soda, dead skin and other nasty stuff you do in bed. Those liquids sit there not only making the mattress dirtier but destroying the function of the structure. It’s hard to work correctly when “waterlogged” with juices.

Plus, modern-day mattress protectors feel and look like regular bed sheets. I even have a review on the very one I use on my mattress. They’re not even that expensive either; I consider it crazy when people don’t use something so practical and affordable.

How Long Should You Leave a Memory Foam Mattress Before Sleeping on It?

It’s best to let your memory foam mattress expand for 48 hours. If you can’t give 48 hours then allow the mattress to expand for 6 hours before sleeping on it.

What Happens If You Sleep On Your Mattress Too Soon?

If you sleep on your mattress before it’s expanded it’s not the end of the world. In fact, many mattress manufacturers recommended you sleep on it the first night because your body heat helps to expand the foam.

I would not worry about it too much. The goal is to give the mattress a few hours before you sleep on it. It can take some mattress a whole week to reach its correct size and sleeping on it won’t hurt.

It’s Been A Week And The Mattress Has Not Expanded.

If it’s been a week and the mattress has not expanded correctly then, unfortunately, you have a defective mattress.

The good news is that this is usually rare. If it’s been a week no need to keep fighting it, contact the company you bought it from to check out the return policy. If you’re curious about returns and what they do with the old mattress check this out.

If you have to return the mattress and want a new one I’ve had good luck with Zinus Green Tea Mattress.

Unwrapping your new mattress

There has recently been a massive influx of boxed mattresses to the market. The reason why has been to reduce the delivery costs, logistics and manufacturing to maximise profits. We are yet to be convinced of the benefits to you the customer with these models. Most of which are cheaper layers of foam and have been created by venture capitalists rather than mattress experts.

Can a quality mattress really be easily rolled?

The reason we have created this detailed guide is due to the number of enquiries we have about opening mattresses such as Eve, Simba, Casper, Herdy and Emma mattresses. We know opening these boxed mattresses can be tricky and if you damage the beds you will void your guarantee. We also provide advice on what to do if you need to send your boxed mattress back under their 30-100 day returns process if you’re not getting on with your new boxed mattress.

We would advise caution with buying a boxed mattress, as rolling and storing them for long periods of time can damage their flimsy foam layers. However, if you’ve recently bought a boxed mattress this guide will give you all the details you need to know.

What is a boxed mattress?

A boxed mattress is usually a foam mattress that has been vacuum packed and rolled to save on storage and delivery space. They have been marketed as NextGen and given different fancy covers. However, in reality, all of these mattresses are variations of the basic memory foam layered mattress. There are a few exceptions such as Herdy but in effect, they are layers of foam, glued together then crushed & rolled to fit into a box. At John Ryan, we don’t sell any rolled mattresses. Our mattresses wouldn’t fit and we wouldn’t subject them to the damages of being rolled and crushed. We did some tests when rolled mattresses entered the market, more on that later.

Boxed mattress brands you may see online:

  • Eve mattresses
  • Casper Beds
  • Leesa mattress
  • The One by Made (Memory Foam Bed)
  • Herdy – Wool and synthetic pocket springs

The mattress enters a big roller which crushes the air out of the foam reducing its size drastically, putting it under stress it is then sealed in a bag, usually heat sealed, and then boxed. It means that a normally large sized mattress can be reduced to fit more on a lorry and make delivery easier for the customer.

However, these mattresses are under great stress when in this position. They want to return to their regular shape and are constrained. Foam can tear, springs can deform and fabric can become stretched and rippled when you unroll them.

We recommend avoiding boxed mattresses if possible, your money is better spent on a Quality upholstered pocket sprung mattress instead like our Handmade Mattresses.

Does rolling a mattress damage it?

A very long time ago now, we trialled rolling a sample Hybrid foam mattress, mainly to see what happened. We were given assurances by suppliers of the machinery that can crush and roll mattresses, that it was fine to do so. There is a time limit of around 6 weeks and after that, the mattress is usually showing some form of stress or damage. However, after 6 weeks we unrolled our two samples. One was Hybrid foam layered up, the other was a FEPS spring unit with a hybrid foam layer.

The Results of Boxed Mattresses:

  • The Layered foam mattress came out with micro tears all across the foam layers when removed the cover off it (Most Eve, Simba, Casper or Leesa mattresses have non-removable covers so you can’t see inside or inspect them)
  • The FEPS spring unit had become stuck to some of the foam and then was slightly distorted once it worked its way loose

The best way to think of it is that the mattress has been suppressed in its packaging, desperately trying to get back to its original shape. Over time cracks and defects can occur in the foam as its stressed beyond its normal tolerances.

Foam can show micro tears and stress cracks once unrolled

Having a rolled mattress means you have to wait hours for it to come back to its original shape which can be frustrating for you the customer.

Are boxed mattresses like Eve and Simba any good?

We have extensively written about some of the newer boxed mattress brands such as Eve, Simba, Casper etc. The issue with these models is they try to be a one size fits everyone, which we disagree with completely.

They also don’t always give you the full breakdown of what exactly is in the mattresses. We have talked at length about the differences between 100% natural latex and synthetic, and why you need to know the blend and density of hybrid foams to truly know what you are getting. Then there is the issue with the One-sided mattresses. So there is plenty to consider and we would rather you read the articles to make your own mind up on these models.

There was a really interesting article in the Telegraph on Eve mattresses posting a record loss in 2018 whilst simultaneously spending an eye-watering £17.2m o advertising. What’s baffling is they only have one product, a basic foam layered mattress. These manufacture methods have been around for 20 years. So why are they spending so much on marketing and not developing the product? Eve doesn’t give the exacting details for us to be able to compare their mattresses. It does beg the question is this more marketing over quality?

If you want to read some more detailed discussions on boxed mattresses, such as Eve, then please start with this comment here.

What is the best alternative to an Eve, Simba or Casper Boxed Mattress?

We would always recommend a two-sided pocket sprung well-upholstered mattress over a one-sided foam bed. If the price is your deciding factor, then we would ask you to look at our Origins 1500 which is at a similar price point to Eve, Simba and Casper as a basis for comparison to a non-rolled mattress. However, the upholstery and spring unit far exceeds the quantities and GSM of the boxed mattresses available. This mattress cannot be boxed, there are simply too many fibres inside it to be easily crushed.

Origins 1500 Mattress By John Ryan By Design

We understand it can be convenient to have your mattress arrive in a box, even though you need to wait around 6 hours for it to fully ‘inflate’ again and return to its original shape. We would also suggest that having two men deliver it to a room of choice with it fully assembled is a far more convenient option!

If you have bought a Simba, Eve, Emma or Casper mattress the rest of this guide will show you how to unwrap it correctly.

How to unwrap your new mattress

So your new boxed mattress has arrived but before you start, we’ve provided this handy guide to show you the easiest and most effective way to unwrap your bed. It may sound simple, but it will save you any damage or scratching your heads! We’ve provided a step by step instruction guide to show you how a Casper, Eve or Simba mattress may arrive.

1. When your new boxed mattress arrives it will be sent out rolled and in a tall box.

We advise that you remove the old mattress and make sure you have some room ready to unwrap the new one. We recommend that you move the boxed mattress to the room of choice before unwrapping it. This is because once unwrapped the mattress will quadruple in size and start to expand. This means handling it becomes somewhat harder and it can be a right fuss if you’re not careful. Once in the room please take the mattress out of the box. It could look similar to the image above.

3. Once out please use a pair of scissors and not a knife. Whilst knives can be used, we warn against it as it’s far easier to slice and damage your mattress with a knife than it is with scissors. Also, we find scissors easier to put down and less dangerous if you stand on them! Turn the mattress until you can see the start of the roll, a bit like looking at the end of the sticky tape. Once you have found it using scissors carefully cut the first piece of tape and wrapping.

4. The mattress will then start to unwrap as seen below. Be careful as sometimes it can start to expand rapidly!

5. Then moving down to the middle tape if present, please carefully cut this.

6. Then moving down to the last piece of tape at the bottom, please again cut through this. This is where the mattress shall be free to unroll and expand, so again just make sure you have some clear space.

7. It will start to unroll fully. You can lay it out on the bed and remove any plastic outer packaging.

8. Once unrolled you will need to leave your mattress and topper for good 6 hours as they start to expand and fill with air. This is because during rolling the air is compressed out of them.

It may be a good idea to open a window and let the mattress ventilate as they offgass. Just like a new sofa or car, there will be some ‘new bed’ smell that comes off the mattress. If your mattress after 6 hours is still not looking fully expanded a quick shake and then another few hours or so should be enough.

Why does my new mattress smell?

Boxed foam mattresses, such as the brands above, are also well known for having a very distinct synthetic plastic or chemical smell when you unwrap them. This is not surprising given they have been off-gassing in their bags for who knows how long. We have a really detailed article on off-gassing which may be of interest. However, with a non-rolled Natural fibre mattress, you don’t get this onslaught of chemical smells when you’re mattress arrives.

How long does it take to get used to a new mattress?

Once you have let your mattress settle for a few hours, we then advise you give it a week or two to sleep on it to properly try it. Lying on it for a night will not give you a true feel for the mattress. If you think of a new mattress like a new pair of shoes you need to let it bed in slightly and allow our self 1-2 weeks to truly get used to it before deciding if it is right for you or not. Especially if you have had your previous bed for a number of years you will have been used to its feel and profile, a new bed will feel different at first.

All of our mattresses are handmade and arrive fully assembled

Our 60 day love it or return it guarantee gives you this peace of mind. If there are any questions once your new John Ryan mattress arrives please don’t hesitate to call us, 0161 437 4419 or email for guidance.

Returning a Boxed Eve, Casper or Simba mattress if you don’t get on with it

Any new mattress will take 2-4 weeks to get used to it. Which is why the decent mattress brands and retailers will give you a no quibble returns policy like our 60 Day love it or return it. Quite often people find foam mattresses incredibly hot during the night or that they get stuck in one position which can aggravate bad backs or aches during the night. Our advice would be to give any new mattress a minimum of 4 weeks and then if not suitable get back in touch with the retailer. The boxed mattress companies are usually really good at collecting your bed. Make sure you’ve saved the box and packaging as some companies will require you to also send this back.

If you really don’t get on with a boxed foam mattress don’t be tempted to just ‘try another one’. Given they all follow the rough construction principle of being one-sided it is highly unlikely based on our experience that you will get on with any foam mattress. It can be really inconvenient having to replace your bed every few weeks so if you don’t get on we would advise you look at a Pocket Sprung 2 -sided mattress instead. Especially one that’s breathable and responsive if you need to turn over during the night. You’ve got a higher chance of sleep success rather than just picking another ‘next day delivery’ mattress.

You’d be surprised at just what you can get for your money when compared to the synthetic boxed foam companies so its best to shop around. Our Origins Pocket 1500 is a great contender to use as a comparison model to the boxed mattress companies based on price. Why settle for a one-sided foam mattress when you can get something much more bespoke and hand made for your money?

Our Origins 1500 shows just how much you can expect for a similar budget compared to the boxed foam beds. Click to view.

Please be aware that after unwrapping any rolled mattress will take anywhere between 4-8 hours to expand to 90% of its full size. It can take further 4-6 hours to reach its maximum. We advise that you don’t sleep or sit on it during this time to ensure it has time to fully expand to its correct size. Always take care when using scissors as not to cut your mattress.

If you’re still scratching your head as to whether to buy into the boxed mattress phenomenon then why not have a look at our Handmade British Mattresses here. All of our mattresses are delivered full size and there are no flimsy glued foam layers to be found!

Review: Will You Sleep Sounder With A SIMBA Hybrid Mattress?

Have you heard of the SIMBA Hybrid Mattress? Many years ago, mattresses weren’t very sophisticated. In fact, the choice was basically soft, medium or hard depending on the needs of your back.

Lately, though, you may have noticed a shake-up in the number and types of mattress available – all of which claim that you will have the best night’s sleep ever.

As he’s getting quite tall, Ieuan’s bed frame was replaced a year or so ago. We choose a simple metal frame bed from John Lewis but let Ieuan choose his own mattress.

The staff waited patiently as Ieuan tested about 10 different mattresses several times. I could have had a large coffee and a muffin plus a tour of the beauty department (never a chore) in the time it took him to settle (literally) on the one he wanted – a SIMBA mattress for his single bed.

Would you believe there’s a double mattress in there?

We hadn’t heard of SIMBA before and assumed that it was a standard memory foam mattress. We were intrigued when, on delivery, we found that the mattress appeared to be vacuum packed and watched it spring to life when it was cut out of its plastic.

We then had to leave it for 3-5 hours to ‘inflate’ before Ieuan could sleep on it. After we all tested it, we agreed that it was the most comfortable mattress in the house.

So, when I was recently offered the chance to review a SIMBA double mattress, it was a no-brainer and I couldn’t wait for it to arrive.

This time though, I wanted to learn a little more about what was about to turn up.

Although it is only 10 inches thick, the SIMBA Hybrid mattress has 5 unique layers which all have a role to play – the Simba 5Ss.

Simbatex Layer

First up is a soft comforting layer that provides support throughout the night. This layer has been developed by SIMBA and contains a synthetic latex layer that also gives a cool feel for the entire time that you lay on it.

Spring Powered Layer​

Featuring 2,500 conical unique springs which adjust individually through your sleep and react to your movement, this layer ensures that you remain supported throughout the entire night.

The Shaped For You Layer

Constructed using high-quality Visco Memory Foam, this layer moulds to the shape of your body and reacts to changes in body temperature and weight so it can sense when you’re lying on it. It springs back into its original shape when you get up.

This memory foam layer also allows you to move naturally in your sleep whilst working to align your spine and promoting healthy posture to relieve tension and pressure.

Visco Memory Foam is hypoallergenic and anti-microbial so it scores well in the hygiene stakes. It is highly resistant to bacteria, mould, mildew, mites, and other odour causing germs, making it a great choice for those with sensitivities or allergies.

It is also effective at reducing motion transfer, which is invaluable for those who share a bed. If your partner is a restless sleeper, or if your partner gets in and out of bed and disturbs you during the night or in the morning, Visco Foam mattresses minimize this disturbance.

Visco Elastic Foam mattresses also tend to last longer and provide more pressure relief than the more traditional ‘sprung’ mattresses.

Seventh Heaven

This layer is a thick support base which is the foundation for the mattress and has 7 different load bearing zones to evenly distribute your weight across the mattress.

Sleep Surface

The entire mattress is encased in a breathable hypoallergenic cover, allowing for freshness to be retained and the temperature to be controlled to a consistent level for the whole of your sleep.

The SIMBA Hybrid Mattress can be used on any type of bed base – slatted platform, flat base, divan or adjustable base and comes with a 10-year guarantee.

SIMBA also offer a 100 day trial with a no questions asked pick-up and a refund.

You can order your SIMBA mattress directly from Simbasleep.com or from John Lewis, Bensons for Beds and Argos.

I was sent a SIMBA Hybrid Double Mattress and it arrived vacuum packed and sealed in a box which is much smaller than the mattress! This means that you don’t have to wrestle with a mattress to get it upstairs – you simply carry the box.

The SIMBA Hybrid Mattress comes vacuum packed.

You then take it out of the box, free it from its plastic covering using the handy cutting tool that comes with it and then leave it for between 3-5 hours to expand into its original shape so that it is ready to use.

Your SIMBA needs 3-5 hours before you can sleep on it for the first time.

If you read the customer reviews, you will no doubt find mention of an initial smell but this is normal with memory foam products and it fades in a day or so.

The mattress comes with full instructions and a nice welcome pack in the box which includes the cutter mentioned above.

The mattress comes with a welcome pack and a special cutting tool.

How Did I Sleep?

Readers know I have been having problems with my back for a while and am coping in the day with pilates and stretching so I had high hopes for my SIMBA.

If you are unused to sleeping on a memory foam mattress, you will find it a new experience. A perusal of the customer reviews on SIMBA’s website shows that whilst the majority took to it like a duck to water, some take just a little longer to get used to it – and I’d put myself in that category.

My previous mattress was a 1400 pocket spring mattress some 10 years old so well overdue for replacement. It had developed a couple of suspicious dips in places which we tried to get over by turning the mattress regularly.

Initially, I found the SIMBA surprisingly firm but, comparing it with Ieuan’s which is now over a year old, it is easy to see that the mattress softens and moulds to the user over time – and so it is already with mine.

I find that I don’t tend to move about so much in my sleep and once of the surprising results of this was a reduction in nocturnal waking – and the resultant trips to the bathroom.

I also felt a little taller and straighter, although my lower back grumbled for a bit probably at being supported properly for the first time in years.

Now after 3 weeks I am already finding I am looking forward to being reunited with my SIMBA at the end of the day. The mattress is already a little softer and ‘fits’ me better.

I still have a moment of surprise when I sit on it and it doesn’t sink like my old one used to and more often than not these days I sleep through to at least 6 am – whereas I would regularly see 4 am and 5 am.

When you get into bed and lie down you can feel the mattress supporting your back and spine without sinking too far into it.

For us ladies of a certain age, heat regulation is also pretty important but I found that the SIMBA Hybrid Mattress’ thermoregulation technology works well and even with a duvet and a throw I don’t overheat and become uncomfortable.

Would I recommend one? Yes, I would and, with SIMBA’s 100-day trial you have absolutely nothing to lose by giving one a try.

Simba Mattress Review – How Good Really Is It?

Numerous online based mattress manufacturers have been entering the market in recent times to shake up the mattress industry. For decades we have been going into busy showrooms and pressured by pushy professionals to purchase mattress, and then we have to repeat this process every few years.

These online companies have removed the middleman which allows the selling price to be significantly lower so more people can enjoy their mattresses. Simba Sleep is one of these online retailers who is leading the revolution with their flagship Simba mattress.

It can be challenging to choose a mattress, especially if you’re shopping online and can’t even lie on it before purchase, so we have created a comprehensive Simba mattress review to show you the benefits and drawbacks of the product and allow you to discover whether it’s all hype or the mattress delivers. This model is in our best overall picks.

Who are Simba Sleep?

Simba Sleep is not new to the bedding industry and has been around since 1979 when they first began to supply the thread that was used to produce mattresses.

They supplied thread that was responsible for the creation of over 50 million mattresses, and this in-depth expertise was then used to transition into mattress design, manufacturing and retailing allowing them to develop into the business that it is today.

Through meticulous planning and design, the mattress has undergone several developments, and they have pushed the market forward from traditionally being a block of memory foam into an extremely technical and revolutionary industry.

Instead of creating many different mattresses, they have made the buying process simple by producing the "perfect" mattress which has been specially designed to provide people of all shapes and sizes with the best nights sleep.

The Mattress

The Hybrid mattress has been developed in partnership with The Sleep To Live Institute after undergoing years of testing and trials after profiling over 10 million people to create a mattress with the optimal level of firmness.

Despite being just 10 inches thick, the Simba Sleep mattress comprises of 5 unique layers that all play an essential role in providing you with an incredible sleep experience.

Simbatex Layer

The top layer is a soft, comforting layer that provides support throughout the night. This layer has been developed Simba and contains a synthetic Latex layer that also gives a cool feel for the entire time that you lay on it.

Spring Powered Layer

This spring layer is constructed using 2,500 unique conical springs that all adjust individually through your sleep and react to your movement. This ensures that you remain supported throughout the entire night. This is a patented feature so the experience will not be replicated with any other mattress in the world.

Memory Foam Layer

This layer is constructed using high-quality Visco memory foam. This layer contours to the shape of your body and reacts to changes in temperature so it can sense when you’re lying on it. Once you have finished sleeping, it then springs back into its original shape.

This Memory Foam layer also allows you to move naturally in your sleep while working to align your spine and promoting healthy posture to relieve tension and pressure. Visco Memory Foam is also hypoallergenic and anti-microbial so not only does it bring a comfortable sleep, but also a hygienic sleep.

Seventh Heaven

This layer is a thick support base which is the foundation for the mattress and has seven different load bearing zones to distribute your weight across the mattress evenly. This foundation base has individual grooves built in, with each zone working together to provide an all in one responsive support solution.

Sleep Surface

The entire mattress has a breathable, hypoallergenic cover. The breathable qualities of the material allow for freshness to be retained and the temperature to be controlled to a consistent level for the whole of your sleep. The cover is 100% polyester which is exceptionally durable while also being great for sensitive sleepers.

​Ordering the Product

This is my favourite part of the process because while doing it I am thinking about the awful memories of having to go from store to store different testing beds before making a final decision after wasting an entire day.

Ordering a Simba Sleep mattress is as simple as a few clicks, then you can sit back and wait for it to be delivered to your door.

Receiving the Product

The product will arrive via next day delivery, vacuum packed and sealed into a box that roughly measures 1m x 0.5m x o.5m, so it’s a small box considering the size of a mattress. It makes it not only easier to deliver but easier to transport it to the room where it will be used.

How often have you had to struggle with a full sized mattress up a windy set of stairs or around a tight bend? Not with the Simba Sleep mattress.

Once you have it in your desired room you will need to remove it from the box and leave it for a few hours to expand into its original shape so its ready to use.

One thing to be aware of is that like all memory foam products; there may be an initial smell. This is normal even though the odour is less noticeable then competitor products because they only use water-based adhesives.

If this is your first memory foam mattress then you may not be used to it, but the smell will always fade after the few days, and it will disappear quicker in a well-ventilated room.

Simba Sleep has included a great opening experience with some excellent packaging. When you open the box, you’ll find a lovely welcome pack and instructions which are formed into a "do not disturb" hanger which is a cool touch. The whole experience is quite exciting considering its just a mattress but Simba Sleep has nailed it.

​So How Does it Perform?

This is the most important thing, isn’t it? So does it deliver what it promises?

The first thing to understand is that it’s difficult to explain the experience of sleeping on the mattress. Simba claims that there is no firmness rating because its "perfect", of course, I was still sceptical, though we now have to agree. The mattress is not too hot, too cold, too soft or too hard and it’s a perfect hybrid mattress which can cater to all needs.

When you lie on the mattress you can feel the firmness supporting your back and spine, but then the memory foam layer kicks in, and you can feel the contouring ability of the mattress creating a snug feel without making you sink far into the mattress which is the problem with most memory foam mattresses.

It’s when you wake in the morning that you can tell how well you slept and when using the Simba Sleep mattress you can feel that any existing aches and pains will have subsided and you almost jump out of bed in the morning ready to attack the day feeling refreshed and energetic.

It’s a great feeling, and you often don’t know how bad the quality of sleep you’re getting until you change your mattress then you can tell the difference. The best way to explain the sleeping experience is that it’s like sleeping on a cloud.

An important factor for my sleep is heat regulation as constant changes in temperature can keep me awake and disturb my sleep. Encouragingly the Simba Sleeps thermoregulation technology works even when using a thick duvet and the mattress never seemed to overheat and become uncomfortable.

Just the simple capability of being able to stay cool will increase the quality of your sleep almost instantly. Being less submerged in foam also means that there is an increased level of air flow.

The mattress also has minimal motion transfer so even if you sleep with a partner who loves to move continuously throughout the night, the movement will not be transferred and felt by you so you will not be disturbed leading to a higher quality of sleep. In my eyes, this is one of the main selling points of the mattress that isn’t found in many other mattresses.

So does the Simba Sleep mattress deliver? YES.

​Benefits

100 day sleep guarantee

Simba Sleep is so sure that their mattress will improve the quality of your sleep that they offer a 100-day guarantee so if you aren’t happy with the mattress within this time frame then you can return it for a full refund with no questions asked.

This is hugely important because any new mattress can feel odd at first and it can often take 14-30 days to fully get used to a new mattress and discover whether you like it or not. If you share a bed with a partner, then it can take you both different periods to decide whether the mattress improves the quality of your sleep or not.

10-year warranty

In addition to the 100 sleep guarantee, a 10-year manufacturers warranty comes with the purchase of any mattress. This excludes general wear and tear but covers defects that may occur within this time.

The average lifespan of a mattress is 8-10 years, and it is regularly that at this point it’s time to replace the mattress, Simba are guaranteeing that it will perform for at least this minimum period.

5 Layer system

The unique five-layer system creates a hybrid mattress that provides the perfect level of firmness and support, so no matter the position you sleep in the mattress will provide the necessary support throughout your sleep keeping you comfortable, yet cool, at all times.

Use on any surface

The Simba mattress is extremely versatile and has been designed to be used on any flat surface even the floor. This is helpful because it means you do not need to spend additional money on buying a new bed frame for your new mattress.

Motion transfer

As explained previously, its lack of motion transfer means that if more two people share the mattress, one sleeper who frequently moves throughout the night will not wake the other person because they will not feel the movement.

UK manufactured

The Simba Sleep mattress is designed and manufactured within the UK, and the materials are also sourced locally to create a genuinely British product. While also supporting one of the countries oldest trades.

Drawbacks

Memory foam smell

Despite only having a small layer of memory foam, the initial smell is noticeable but not completely off-putting. However, this smell usually is present with any memory foam mattress that you buy in today’s market. The smell does disappear within a few days

Different people are more reactive to the smell; some need to leave it in a separate room for a few days, whereas others can begin using it straight away and the smell doesn’t bother them.

​Final Word

The Simba Sleep mattress is taking the market by storm, and rightly so. Its revolutionary comforting five-layer technology combined with its affordable price means that it is accessible to almost anyone who is looking to purchase a new mattress.

Its 100 day sleep guarantee means that you have nothing to lose by trying it but potentially have much to gain especially if you’re currently struggling to sleep or are experiencing aches, pains or back soreness. It’s important to note that it often takes several nights to get used to the mattress, but it will quickly transform your sleep.

There is an overwhelming number of positive reviews and support for the product especially from those who have been suffering from back pain and have noticed the pain subside since beginning to use the mattress.

Once you experience this mattress, you’ll begin to see why online mattress stores have started to disrupt the traditional mattress buying marketplace.

Numerous online based mattress manufacturers have been entering the market in recent time to shake up the mattress industry. For decades we have been going into busy showrooms and pressured by pushy professionals to purchase mattress and then we have to repeat this process every few years.

These online companies have removed the middleman which allows the selling price to be significantly lower so more people can enjoy their mattresses. Simba Sleep is one of these online retailers who are leading the revolution with their flagship Simba mattress.​

It can be difficult to choose a mattress, especially if you’re shopping online and can’t even lie on it before purchase, so we have created a comprehensive Simba mattress review to show you the benefits and drawbacks of the product and allow you to discover whether it’s all hype or the mattress really delivers. ​This model is in our best overall picks.

Who are Simba Sleep?

Simba Sleep are not new to the bedding industry and have been around since 1979 when they first began to supply the thread that was used to produce mattresses.

They supplied thread that was responsible for the creation of over 50 million mattresses, and this in depth expertise was then used to transition into mattress design, manufacturing and retailing allowing them to develop into the business that it is today.​

Through meticulous planning and design the mattress has undergone several developments and they have pushed the market forward from traditionally being a block of memory foam into an extremely technical and revolutionary industry.​

Instead of creating a number of different mattresses, they have made the buying process simple by producing the "perfect"​ mattress which has been specially designed to provide people of all shapes and sizes with the best nights sleep.

The Mattress Itself​

The Hybrid mattress has been developed in partnership with The Sleep To Live Institute ​after undergoing years of testing and trials after profiling over 10 million people to create a mattress with the optimal level of firmness.

Despite being just 10 inches thick, the Simba Sleep mattress is comprised of 5 unique layers that all play an important role in providing you with an incredible sleep experience.​

The top layer is a soft comforting ​layer that provides support throughout the night. This layer has been developed Simba and contains a synthetic Latex layer that also gives a cool feel for the entire time that you lay on it.

Spring Powered Layer​

This spring layer is constructed using 2,500 conical unique springs ​that all adjust individually through your sleep and react to your movement. This ensures that you remain supported throughout the entire night. This is a patented feature so the experience will not be replicated in any other mattress in the world.

Memory Foam Layer

This layer is constructed using high quality Visco memory foam. This layer contours to the shape of your body and reacts to changes in temperature so it can sense when you’re lying on it. Once you have finished sleeping, it then springs back into its original shape.

This Memory Foam layer also allows you to move naturally in your sleep whilst working to align your spine and promoting healthy posture to relieve tension and pressure.​ Visco Memory Foam is also hypoallergenic and anti-microbial so not only does it bring a comfortable sleep, but also a hygienic sleep.

This layer is a thick support base which is the foundation for the mattress, and has 7 different load bearing zones to evenly distribute your weight across the mattress.​ This foundation base has individual grooves built in, with each zone working together to provide an all in one responsive support solution.

The entire mattress is encased in a breathable hypoallergenic cover. The breathable qualities of the material allows ​for freshness to be retained and the temperature to be controlled to a consistent level for the whole of your sleep. The cover is made from 100% polyester which is extremely durable whilst also being great for sensitive sleepers.

Ordering the product

This is my favourite part of the process, because whilst doing it I am thinking about the awful memories of having to go from store to store testing different beds before making a final decision after wasting an entire day. Ordering a Simba Sleep mattress is as simple as a few clicks, then you can sit back and wait for it to be delivered to your door.​

Receiving the product​

The product will arrive via next day delivery, vacuum packed and sealed into a box that roughly measures 1m x 0.5m x o.5m so it’s a small box considering the size of a mattress. This makes it not only easier to deliver, but easier to transport it to the room where it will be used. How often have you had to struggle with a full sized mattress up a windy set of stairs or round a tight bend? Not with the Simba Sleep mattress.​

Once you have it in your desired room you will need to remove it from the box and leave it for a few hours to expand into its original shape so its ready to use.​ One thing to be aware of is that like all memory foam products, there may be an initial smell. This is normal even though the odour is less noticeable then competitor products because they only use water based adhesives.

If this is your first memory foam mattress then you may not be used to it but the smell will always fade after the few days and it will disappear quicker in a well ventilated room.

Simba Sleep has included a great opening experience with some excellent packaging. When you open the box you’ll find a lovely welcome pack and instructions which are formed into a "do not disturb" hanger which is a cool touch. The whole experience is quite exciting considering its just a mattress but Simba Sleep has nailed it.

So How does it perform?

This is the most important thing isn’t it? So does it deliver what it promises?

The first thing to understand is that it’s difficult to explain the experience of sleeping on the mattress. Although Simba claim that there is no firmness rating because its "perfect", of course I was still skeptical​, though we now have to agree. The mattress is not too hot, too cold, too soft or too hard and it really it a perfect hybrid mattress which can cater to all needs.

When you lie on the mattress you can feel the firmness supporting your back and spine, but then the memory foam layer kicks in and you can feel the contouring ability of the mattress creating a snug feeling without making you sink far into the mattress which is the problem with most memory foam mattresses.​

It’s when you wake in the morning that you can really asses how well you slept and when using the Simba Sleep mattress you can feel that any existing aches and pains will have subsided and you almost jump out of the bed in the morning ready to attack the day feeling refreshed and energetic.

It really is a great feeling and you often don’t know how bad the quality of sleep you’re getting until you change your mattress then you can really tell the difference. The best way to explain the sleeping experience is that its like sleeping on a cloud.

An important factor for my sleep is heat regulation as constant changes is temperature can keep me awake and disturb my sleep. Encouragingly the Simba Sleeps thermo regulation technology works even when using a thick duvet and the mattress never seemed to overheat and become uncomfortable.

​ Just the simple capability of being able to stay cool will increase the quality of your sleep almost instantly. Being less submerged in foam also means that there is an increased level of air flow.

The mattress also has minimal ​motion transfer so even if you sleep with a partner who loves to move constantly throughout the night, the movement will not be transferred and felt by you so you will not be disturbed leading to a higher quality of sleep. in my eyes this is one of the main selling points of the mattress that isn’t found in many other mattresses.

So does the Simba Sleep mattress deliver? YES​.

Benefits

​Simba Sleep are so sure that their mattress will improve the quality of your sleep that they offer a 100 day guarantee so if you aren’t happy with the mattress within this time frame then you can return it for a full refund with no questions asked.

This is hugely important because any new mattress can feel odd at first and it can often take 14-30 days to fully get used to a new mattress and discover whether you like it or not. If you share a bed with a partner then it can take you both different periods of time to decide whether the mattress improves the quality of your sleep or not.
