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.

Sleeping on a Memory Foam Mattress Too Soon

Why It Needs 24 Hours to Expand?

Well firstly, you you should know that the off-gassing happens in the first couple of hours. If it’s okay to sleep on your new memory foam without waiting for 24 hours to allow it to expand, then why do we still need 24-48 hours?

It’s all about the manufacturer guarantee. They claim that if it doesn’t fully open up and you did sleep on it then you’ll void that guarantee. If you’ve paid several hundred or even thousand on a new bed – you have to think twice about risking your money back opportunity.

But another important question is that, what should you do if your mattress takes more than 24 hours to expand fully?

What to Do When Memory Foam Mattress Not Inflating?

Memory foams have different thickness levels. You can choose from an 8-inch mattress to a 13-inch memory foam bed. They are designed with open cells to conform to various shapes of sleepers using the bedding. Before they leave the factory, these mattresses are folded and compressed using a machine roller to fit into a small package.

The best way to use a memory foam is to let it expand before using. However, if it’s not inflating, there are simple tricks you can do to enjoy its comfort after 24 hours of arrival. Check these tips to help you out:

  • Unbox the memory foam within the three days of arrival. Remove the plastic cover using your hands. Never use any sharp objects like a knife and scissors when removing the mattress from the package to avoid damages.
  • Allow the foam to adjust in room temperature, which may take up to a couple of hours until it begins expanding. This step is essential, especially when you get your memory foam in the winter season. Foam mattresses tend to become more brittle if it’s still tight, which can lead to tearing.
  • Unroll it in a spare room so the open cells of the memory foam will expand and inflate freely. Separate each layer of the foam carefully to allow them to grow. Pull them in uniform motion with slow and steady hands.

What Are the Possible Reasons Why your Lucid Memory Foam Mattress is Not Expanding?

If your Lucid memory foam mattress is not expanding, there might be an essential step you haven’t performed after unrolling it. First, it needs time to develop, typically within 72 hours before you can finally use the mattress. So wait for it until it becomes entirely usable in its original size.

Some memory foam mattresses take one week to air out, but they lose the new-foam smell at the same time. It is already fully plumped when you noticed that the smell is gone. And you can use a mattress topper to retain the plumpness of your new memory foam.

Key Takeaways

The truth is, each mattress has its own expansion time and features. Therefore, the time required before they fully expand will depend on the model and brand you purchased.

Before you can move it to your bedroom, most memory foam mattresses that usually take 24 hours to decompress may still need at least two hours. Waiting for 24 hours or 72 hours to allow a bed to expand is a traditional belief.

Most of the mattresses offered on the market today only take a short time to decompress, and you can sleep on the right after unboxing them. So there’s nothing to worry about sleeping on your mattress too soon. You won’t damage your memory foam while sleeping on it during the first night.

The key is in the type of memory foam used in your mattress. The higher quality the foam, the better and faster it will expand in less than 24 hours.

Dreamcloud Mattress How Long to Expand | Everything You NEED To Know!

I’m incredibly thrilled about today’s review since I’ll be taking a look at one of the latest beds on the market: the DreamCloud crossbreed bed mattress. This bad young boy combines high-density foam with encased coils for a sleeping experience that assures to be as lavish as it is supportive.

To see how well this crossbreed measures up to that goal, I’ve placed it with a series of tests to determine its overall comfort as well as establish what type of sleeper would take advantage of it most.Continue analysis below for my complete review of the DreamCloud cushion. Don’t have time to read it all?


The DreamCloud showcases an astoundingly tall profile for a mattress at a tremendous 15 inches. The eight-layer construction is broken down into foam as well as covered coil parts, which work in tandem to supply the sleeper with a company innerspring lift as well as a lot of comfortable pressure alleviation.Given all the various materials at play right here, I’m stoked to dive into these layers to see exactly how well they connect with each other.Dreamcloud Mattress How Long to Expand

Cover.The cover is made up of a cashmere and also polyester mix for a luxuriously soft really feel up top. It’s likewise quilted with memory foam, which supplies the sleeper with immediate pressure alleviation.

Foam Layers.Below the cover, you’ll discover 3 thin layers of foam. While these areas are soft to the touch and provide some gratifying sinkage, they also respond swiftly to pressure, so you won’t feel embeded the mattress. The middle of these three layers is specifically vital for the temperature regulation of the DreamCloud as it’s consisted of perforated latex foam. Latex in general is fantastic at dissipating warmth, so the addition of these tiny ventilations encourages a lot more cooling.

Pocketed Coils.The lower layer of foam changes into the stronger support section of the bed mattress, which is comprised of a pocketed coil system. These individually covered springtimes give the bed excellent bounce and aid to distribute motion throughout the structure. The coils also help in managing temperature level as the spaces in between them permit stable air circulation.

Structure Layer.A thin layer of high-density polyfoam lies at the base of the bed mattress, with the primary function of supporting the stolen coils and providing an audio foundation for the entire.


After taking a look at the construction of the DreamCloud, let’s conversation regarding the firmness as well as really feel. I began by using light hand pressure to the bed mattress and also promptly felt the soft foam of the quilted cover as well as leading layers.

My hand penetrated the product and I might really feel some instantaneous pressure relief. Pushing in additionally, I started to communicate with the taken coils listed below and experienced a pleasurable lift from the springtimes.

Now I wish to keep in mind that people of different physique and also shapes will certainly feel firmness in a different way. As opposed to giving simply my opinion on the total firmness degree of the DreamCloud, I got three other people to give their point of view too. This will offer you a much better feeling of the firmness range you can anticipate from the mattress.

As you could see in the chart over, the testers were virtually in arrangement concerning the firmness of the DreamCloud, giving it an average ranking of 7.75. Compare this to the market standard of 6.5 for medium firmness and also it’s clear that this cushion is rather solid.
I directly offered the bed a 7.5 and agree with the remainder of the testers that it’s most definitely a strong bed.

While you’ll feel some slight sinking from the plush foam leading layers, the separately wrapped coils in the core will certainly raise you from the bed as well as make you feel like you’re resting on top of the bed mattress.Dreamcloud Mattress How Long to Expand


Instead of just defining the feel of the DreamCloud to you, I wanted to offer a graph of where someone could feel pressure points create while pushing it. To do this, I positioned a pressure map in addition to the mattress and also lied on my back, side, and stomach. You can see the outcomes on the picture below where pressure is stood for from blue (reduced pressure) to red (high pressure).

Back.When on my back, my weight was equally dispersed throughout the mattress, so I really did not seem like I was sinking into the bed in all. The quilted cover provided quality alleviation at my back area and also the stolen coils assisted to raise me from the bed and also keep my back in alignment.

Side.As you can see in the chart over, once I rolled onto my side, I started to feel pressure developing at my shoulders and hips. However, I still really felt sustained and also the leading foam layers relieved exactly what pain I really felt in this placement.

Stomach.Changing over to my stomach, I thought the DreamCloud did a great task of lifting my hips up and also from the bed, which is vital for stomach sleepers. I should discuss that I had the ability to transition across these placements with relative ease.

If you intend on sharing your bed with a partner, you’ll need to know just what it’ll seem like when the various other individual crawls out of bed in the early morning or tosses around at night. This following examination is intended to demonstrate the intensity of motion that is observable from one side of the mattress to the various other.

To show this motion transfer, I went down a 10 lb. steel ball from heights of 4 inches, 8 inches and also 12 inches and also gauged the disruption it triggered: the larger the lines, the bigger the disruption.

The DreamCloud reveals a percentage of disruption for the 4 inch decrease, which mimics someone rolling about and adjusting their placement on the other side of the bed. While the 8 and 12 inch drops reveal somewhat bigger spikes, I would certainly still consider the mattress to be respectable at separating motion, many thanks to the independently covered coils. This indicates you’re not most likely to be too interrupted by your bed friend’s twelve o’clock at night vibrates, makings this a terrific alternative for couples.


When purchasing a brand-new bed, many people want to know whether they’ll seem like they’re sinking “into” the bed mattress or laying “on top” of it. To visualize this sinkage, I placed 4 rounds of varying sizes and also thickness (a 6 lb conditioning ball, a 10 lb steel ball, a 50 pound conditioning ball, and a 100 pound conditioning ball) on the bed mattress and also measured what does it cost? they pressed the surface.

The variants in size, weight and also density are indicated to mimic different body components and different sized sleepers.Dreamcloud Mattress How Long to Expand

The sinkage test on a DreamCloud cushion with spheres considering 6 lbs, 10 pounds, 50 pounds as well as 100 lbs.

• 6 pound conditioning ball: 1.5 inches of sinkage.
• 10 lb steel sphere: 2 inches of sinkage.
• 50 pound medicine ball: 4.5 inches of sinkage.
• 100 lb conditioning ball: 5.5 inches of sinkage.

While you’re mosting likely to experience some immediate sinkage from the soft foam on the top, by the time you sink with those layers, you’ll strike the wrapped coils and really feel great support. This combo will appeal to a large range of sleepers, however will please back as well as stomach sleepers particularly.


If you’re going to share your bed with a partner and also need to make use of the whole surface of the bed mattress, it’s mosting likely to be important for you to consider the quantity of edge assistance it’ll supply.

I’m especially interested to see if the DreamCloud will certainly suffer the exact same fate as various other compressed bed-in-a-box mattresses that fail to meet the edge support of more conventional innerspring designs.

Pushing my back, I really felt as sustained beside the bed as I carried out in the center. Pushing closer to the side, I experienced a little compression because of the top foam layers, however absolutely nothing as well remarkable.

Changing to my side, I again observed compression in the foam layers, but it really did not carry over into the covered coil system listed below. This system, along with the polyfoam edge support around the cushion, did an excellent task of sustaining my weight.

In this setting, I wanted to replicate what it would seem like to be sitting on the bed in the early morning when you’re tiing up your shoes and also preparing yourself for the day. A lot of foam bed mattress experience serious compression in this placement, yet the DreamCloud in fact held up fairly well.

Can You Sleep On A Memory Foam Mattress Before 24 Hours?

First, we’d like to congratulate you on your first mattress in a box. Whether your new mattress is memory foam, latex, or a hybrid, it takes time to expand after unpackaging. You’ve probably heard the myth cautioning you to avoid sleeping on your bed while it expands, but in this article, we explain why that’s not absolutely necessary.

Most companies ask you not to use the mattress until 24 hours after you’ve unboxed the bed to ensure the quality of their product is at its fullest potential when you sleep on it for the first night. But when nighttime rolls around and its time to go to sleep, waiting to use your new bed can be inconvenient.

So, what happens when you sleep on a memory foam bed before those 24 hours are up? In our article, we’ll discuss how long you should really wait before using your foam mattress and what you can do to minimize the wait.

Can I Go To Sleep Right After the Mattress Has Expanded?

Truth is, you can sleep, roll around, and step on your mattress as much as you want while it expands. Regular mattress use will only decrease the material’s expansion time.

If you want to sleep on it before the 24-hour mark, just remember the mattress won’t feel its very best until it expands to its full size. If the first night on your new bed isn’t all you’d dreamed it’d be, give it more time before calling for a return. If a mattress has a ten-inch profile, then you need to wait until it’s expanded to 10 inches tall and the corners have grown to their full shape. If your bed is still uncomfortable after full expansion, then it’s time to call.

A few bloggers suggest waiting to put your mattress protector and sheets on your new bed only after the corners have fully extended. However, in our experience, we’ve found you don’t have to wait for the corners to take shape to go to bed, as you’re typically not sleeping on the corners of the mattress; this lets those corners continue to expand throughout the night. Mattress protectors and sheets are not tight enough to prevent the corners from expanding and should not have an impact on your bed’s expansion time.

There are a few reasons why manufacturers don’t want the bed used within 24 hours of unrolling. The 24-hour rule exists mainly as a precaution to ensure the mattress has fully extended and there’s no damage to the bed’s foam.

However, memory foam fresh out of the box is more versatile than aged foam. Rolling across it won’t do much harm. It the mattress doesn’t assume its original shape after the allotted expansion period, then the foam layers may be defective. Contact the company for exchange or return information.

The second reason why brands want you to wait to sleep on their beds is the risk of off-gassing. Nobody wants to fall asleep on a chemical-smelling bed, and jumping to sleep on a freshly unpackaged mattress may be unpleasant. While most foam mattresses are CertiPUR-US® certified, there still are slight off-gas smells. Letting your bed air out for the allotted time prevents you from dealing with any unpleasant scents.

How Do I Speed Up the Expansion Process?

Constant movement, bodyweight, and heat activate the foam, loosening the material. Laying down on the mattress and rolling around for a few minutes as well as standing on the end of the mattress and walking around the edges should make it expand faster.

My Foam Bed Isn’t Expanding

While some mattresses expand quickly, there are others that have a harder time expanding. If you run into this problem, try activating the memory foam with body heat.

Roll around and walk on the mattress— almost as if you’re giving the bed a massage— and sleep on it for a few days. Afterward, it should expand to its correct size.

The Mattress Hasn’t Expanded After a Week!

If a foam mattress doesn’t expand after five or seven days, then you most likely have a defective bed.

A mattress not expanding is very rare; but if you’ve given your mattress a whole week to expand and it hasn’t, call customer service to inform them of the defect and initiate the return policy.

Taking Care of Your Foam Mattress

Whether you have a hybrid or a gel memory foam mattress, you’ll need to care for it properly to maintain its longevity. Innerspring and hybrid mattresses only need a box spring, whereas memory foam mattresses require a more sturdy foundation. All mattresses, though, need periodic cleaning.

Choosing a Foundation

Foam beds need a solid, flat mattress foundation.

Flexible box springs work well with an innerspring and hybrid mattress; however, a memory foam mattress paired with this type of base will cause the middle to sag, resulting in discomfort.

Memory foam needs a bed frame with either a solid flat surface or a slatted base. Platform beds are a good option, as long as the slats are less than 3 inches apart to prevent the foam material from dipping; this could cause the mattress to deteriorate quickly and product indentations in the material.

Cleaning Tips

Some foam mattresses have removable, machine-washable covers. If you have a mattress without a removable mattress cover, you’ll have to spot clean it with room temperature water mixed with mild detergent.

It’s a good idea to vacuum the mattress at least once a month to remove loose foreign debris and any hair. These same cleaning tricks work on a mattress topper.


You now understand the rules behind allowing a foam mattress to expand and you have a few cleaning tips up your sleeve. You even know what to look for in foundations and bed frames that are best for foam mattresses. To learn more about maintaining your new mattress, read our other guides.

  2. Open the brown shipping boxat the top within two weeks of receiving your mattress. Your mattress will be sealed inside within two layers of plastic.
  3. Slide the mattress out of the boxby laying the box on its side.
  4. Find the edge of thewhite layer of plasticand begin to unrollthe outer white layer of plastic only, and remove it from the mattress. The mattress will still be sealed within a second layer of plastic.Do not cut both layers of plastic at the same time, or the mattress will immediately begin to expand while rolled.
  5. Unroll the mattressand position it — either on the floor or on your bed frame — in a spot where it has ample room for it to expand to full size.
  6. Finally, carefully cut the remaining clear layer of plastic and remove it from the mattress.The mattress will fill to full size rather quickly (but not in any dangerous or alarming way). Call in friends and family members, as this is especially fun to watch. Within 30 minutes, you can lie on your new mattress. Within a few hours, your mattress will be fully expanded.
