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
|amerisleep||Can 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.|
|BEDBOSS||Should 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.|
|Casper||Can expand and be ready to sleep on in a few minutes but keep in mind that some will take longer.|
|Classic Brands||Allow 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 Bedding||6 to 7 hours from opening.|
|Helix||Give it 2 hours to regain its shape, and you’re done.|
|Layla||Will 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.|
|Leesa||May take up to an hour to expand but give it 24 hours to fully expand and be at its best|
|Linenspa||Up 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.|
|LUCID||Up to 48 hours, but if it’s fully expanded after 24 hours you can go ahead and sleep on it.|
|Lull||Will do most of the expanding in 2 to 5 hours and fully expand in 24 to 48 hours.|
|MLILY||Should be ready in 24 hours. Walking on it while it’s on the floor can help speed up the process.|
|Nectar||Between 24 to 72 hours to expand.|
|Nest Bedding||You 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 Sleep||let it expand up to 72 hours|
|Puffy||Allow it to expand and breathe for a few hours before putting bedding on it.|
|Purest Of America||Allow 24 to 72 hours to fully recover.|

|Tuft & Needle||Only takes several hours to reach the proper specifications, but in some cases, it may take up to 5 days.|
|Tulo||Allow it to sit for an hour before using it.|
|Zinus||48 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.

What Happens If You Sleep on a Memory Foam Mattress Before 24 Hours
So you’ve got a new memory foam mattress, you’re excited – in the back of your mind you remember some rule of thumb about waiting for a day before sleeping on it. The manufacturers say to wait for at least 48 hours before it expands fully, especially the ones that are still in the box. But if you’re curious what happens if you sleep on a memory foam mattress before 24 hours, then you’re in the right place.
Sleeping on a Memory Foam Mattress Too Soon
There are some essential things to consider before sleeping on a memory foam mattress too soon. For instance, most memory foam mattresses require up to two days before it goes back to its original size and form. After all, these mattresses are vacuum sealed, pressed and rolled tightly to fit in the packaging.
But can you sleep on a memory foam mattress the first night? Well, you can relax, jump, or do whatever you want with your bed as soon as you received it. Using it right away won’t cause any damage but will only speed up the process of expanding the foam.
This 24-hour recommendation is to ensure customer satisfaction and manufacturer guarantees.It also gives any off-gassing time to dissipate.
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? Well, there are rare cases wherein compressed memory foam mattresses don’t fully extend. If that’s the case, then you can ask your seller what to do to make it expand or ask for a new one.

Zinus Mattress – How Long to Expand
Most Zinus Memory Foam Mattress like the 12 Inch Green Tea Mattress need 48 to 72 hours to relax and decompress and restore to its original shape. That’s why the Zinus company manual advice customers to open the packaging within 72 hours of arrival to make sure the mattress they ordered will fully grow to its potential.
And with the green tea extract infuse in the foam, you will not inhale hazardous and harmful smell with you first open the packaging. It will typically dissipate after laying the mattress in a well-ventilated area.
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.
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.
How Long Do Mattresses Last? The Results May Shock You!
Mattresses are pretty expensive — one quick glance at our buyer’s guide will confirm this fact. This is why many people do not replace them – not even after many years of use.
They do not want to spend a lot of money on a new one. Besides, now you can delay the process of buying a new one if you do an excellent job at maintaining your existing one.So, how often should you replace your mattress?
It doesn’t matter which type of bed you have. Most of them are ready for replacement within ten years to ensure a good night’s rest (old mattresses can hurt your sleep quality). Besides, it can last beyond ten years on average, if the owners maintain it properly.

Outline: Zinus Mattress Review
We are very thorough in our reviews, so in order to make this post easier for you to digest, below is a jump-to list. You can click the links to go to a particular section within the review.
Buying A Zinus Mattress
Zinus very likely could be the #1 best selling mattress on Amazon. It’s really cheap and that’s the primary reason that people buy it.
Like most other online mattresses,Zinus comes with free shipping, whether you purchase through Zinus.com or Amazon. It also ships compressed inside a box and will usually arrive within three to five business days of when you place your order, at least if you’re in the contiguous United States.
When the package arrives, all you have to do is drag that sucker inside and tear off all of the plastic wrapping.The unboxing process takes less than 15 minutesstart to finish. You will want to give the bed 48-72 hours to fully inflate. Because it uses a lot of memory foam, it needs some extra time to return to its intended form. This is common with a lot of memory foam mattresses.
The Zinus Green Tea mattressis backed by a 10-year warranty. As an FYI, most beds come with at least a 10-year warranty.
Price Of The Zinus Green Team Mattress
As mentioned previously,this bed is cheap. In fact, depending on the height that you choose (6″, 8″, 10″, or 12″) the Green Tea mattress might bethecheapest bed available. Here’s a pricing breakdown for the 12″ model.
|King / Cal King||$420|
Keep in mind thatprices tend to fluctuate seller to seller on Amazon. For example, typically, when Amazon is the actual vendor for the mattress, we see it more heavily discounted than when Zinus is selling the mattress themselves. Regardless, though, you can usually find the 10″ model for around $200 on Amazon.
Zinus Memory Foam Mattress Construction & Layers
The Green Tea mattress ismade entirely of foam, but the exact construction depends on which height you choose. Below is a construction breakdown for the 12″ Green Tea mattress.
Inside the 12″ Zinus Green Tea mattress
The 6″ bed has only two layers. It has egg crate support foam on the bottom and memory foam on top. The 8″ and 10″ models both have three layers. They have support foam on the bottom, transition foam in the center, and memory foam on top. The 12″ model just adds a second layer of egg crate support foam on the bottom.
Construction side view of the 12″ Green Tea mattress
All of the foams in this mattress are CertiPUR-US certified. This assures you that the mattress has been tested and certified by an independent laboratory to meet specific criterion for physical performance, indoor emissions, and environmental stewardship, and is made without ozone depleters, heavy metals, or formaldehyde. Also, the Green Tea mattress has been tested and passed the requirements of the Cigarette Smoldering Test and the Open Flame Test.
What We Think Of The Cover On Zinus Green Tea
The cover for this mattress is made of a knitted jacquard fabric. It’s white and soft, but to be honest, it’s not our favorite cover.It’s thin and bunches up easily. You can actually grab the cover and pull it up in the air a good six inches.
The cover is removable, but Zinus actually states that removing it can affect your warranty, and we agree that you should not remove it, because it’s just a pain. If it gets a stain that you must remove, justuse some warm water and mild detergent to spot clean. That should do the trick.
Plain Jane cover, but it’s fine
Also, to extend the longevity of this bed, you’ll want torotate it every three months as a preventative measureto protect against sagging or permanent indentations. Egg crate foam is probably the least durable foam that you’ll find inside a mattress. As such, we would implore you to rotate it regularly if the bed sees a lot of use. If it’s just your Airbnb mattress, rotate it as needed, not necessarily at set intervals. And this bed is not flippable.
Feel/Firmness Of This Memory Foam Bed
The Green Tea mattress is amedium-soft on the soft-to-firm scale, and has a pure memory foam feel. By this, we mean that you’re going to slowly melt into the material as it surrounds you, like a big hug, or like super comfortable quicksand.
We also noticed that the firmness of this bed changes per season because of the temperature.This bed seemed to be firmer in colder weatherand softer in warmer weather.
Given that the Green Tea mattress has a true memory foam feel,you get a good amount of that stuck-in-the-mud feeling. Switching positions does take extra effort and could leave you feeling restless if you tend to rotate between sleeping positions frequently during the night.
That said, we do think the Green Tea mattress is comfortable, it’s just thatyou have to really like memory foam to get this mattress.
Will Back And Stomach Sleepers Like Zinus?
Typically, back and stomach sleepers prefer firmer mattresses—that’s not the Zinus Green Tea mattress. We do not think this will be a good mattress for back sleep and stomach sleepers unless you’re on the lighter side (i.e. under 140 lb).
Not designed for back or stomach sleepers
If you sleep predominately on your back, make sure to check out our list of the Best Mattresses for Back Sleepers. Same thing for stomach sleepers—see our list of the Best Mattresses for Stomach Sleepers.
Side Sleepers—What Will They Think Of Zinus?
Why yes, it is. The Green Tea mattress isbest for side sleepers. It’s soft enough to offer great pressure relief for the hips and shoulders when you’re on your side.
Ideally suited for side sleepers
As for combo sleepers, because you get that stuck-in-the-mud feeling,you’ll face a little resistance while moving around on the bed. If you’re of a lighter build, it’ll be easier for you, while heavier people will sink into the mattress more and get that quicksand feeling.
To answer your question, though, yes, Zinus will work for combo sleepers, but it wouldn’t land anywhere near our list of the Best Mattresses for Combo Sleepers.
Can Zinus Green Tea Handle Bigger People?
Short answer: No. We usually recommend heavier individuals go for a hybrid or spring mattress as opposed to an all-foam bed. While the 12″ bed is better than the 6″ bed for heavy people, overall, we can’t recommend the Zinus Green Tea mattress for individuals that weigh 250 lb or more. Foam beds just don’t typically have the long term support that coil beds do.
