How Long Does It Take To Adjust To A Memory Foam Mattress?


There are a number of glowing reviews all over the internet for memory foam mattresses. It’s true – memory foam mattresses are extremely comfortable and usually are a treat to sleep on.

However, what most of these articles won’t tell you is that there is usually a break-in period and that it takes time for you to adjust to your new mattress.

How long does it take to adjust to a memory foam mattress?

This is what we are going to answer in this article today. Let’s get started.

Give It At Least 30 Days

The quick answer is that it usually takes at least 30 days for you to adjust to your new memory foam mattress.

This may seem like a long time but in the grand scheme of things, 30 days is nothing.

It usually takes this long because night after night, your memory foam mattress is slowly adjusting to the contours of your body.

In the long run, this will mean better sleep with proper support for your body’s pressure points. However, in the short run, you need to give the mattress time to adjust.

It Takes Time To Reach Its Intended Shape

It’s important to keep in mind that if you have just received a memory foam mattress it may take at least 48 hours for it to reach its full shape.

This is because most memory foam mattresses are compressed when they are shipped in order to make it easier to send via mail.

We recommend letting your new memory foam mattress breathe when you receive it – wait until bedtime to put bedding and linens on it. This will help it reach its original shape more quickly.

If you are sleeping on a new memory foam mattress the first or even second night, keep in mind that it has not yet reached its original form. After a few days, it should become much more comfortable.

The First 30 Days Are The “Break-In” Period

Buying a new mattress is a lot like buying a new pair of shoes. Think of the most comfortable shoes you own – they probably weren’t super comfortable when you first bought them, right?

You had to go through an initial break-in period before they became incredibly comfortable.

The same is true with memory foam mattresses. Even the finest memory foam mattresses can start out being a little too firm and require time to break-in and get used to your specific height, weight, and body shape. Remember this if your first 30 days aren’t extremely comfortable.

Keep in mind as well that these changes come slowly and can be hard to notice night after night.

We recommend jotting down notes week after week or even consider starting a sleep diary to document your nightly sleeping habits.

After a month, you will probably find that the mattress has adjusted and you are sleeping well.

Days 30 To 90 Is When You Should Fully Adjust

Most people will start to feel that their mattress is fully breaking in within the 30 to 90-day mark.

At this point, you should notice that you are able to sleep through the night comfortably and without issues.

After 90 days, if you find that you are still not comfortable, it may be time to consider returning the mattress.

Alternatively, there are a number of great mattress pads that can make your memory foam mattress softer (or harder), and we recommend using one of these if need be.

Add A Mattress Topper If Your Mattress Is Uncomfortable

If after the 30 to 90-day mark you find that your new memory foam mattress is still uncomfortable, we recommend adding a mattress topper to help you sleep more comfortable.

Pad adds enough support to make it extremely soft, but also provide enough support so you sleep peacefully.

Many pads are available in Full, Queen, and King sizes, meaning it will most likely fit on your memory foam mattress.

We highly recommend a mattress pad if you are having trouble adjusting to your new memory foam mattress.

Keep In Mind That It Works Both Ways

It’s crucial to keep in mind that when you get a new mattress, two crucial things are actually happening. The mattress is becoming more broken in and used to your specific body, but also, you are starting to adjust to the mattress itself.

Memory foam mattresses work differently than traditional innerspring mattresses and do a much better job of supporting your body.

However, if you have slept on an innerspring mattress your whole life, it might feel strange at first to sleep on a memory foam mattress.

This is natural and all part of the process. Just give it time for both you and your mattress to adjust.

Make Sure That Your Room Is Warm

If you live in a cold environment, you may find that your memory foam mattress is too firm and thus extremely uncomfortable.

This is because memory foam is temperature sensitive, and actually become more rigid in cold environments.

Conversely, in warmer environments, it becomes more flexible and soft. Keep this in mind if you find yourself having trouble adjusting to the mattress.

What Can I Do To Quickly Make My Mattress More Comfortable?

The best way to make your mattress more comfortable is to use it more often. This may sound obvious, but there are ways to slowly expedite this process.

You do not want to spend excessive time in your bed since this can cause poor sleep hygiene, but consider rolling around in your bed before you leave your bed in the morning.

Additionally, you can try walking on your bed to help break it in more and get the memory foam used to weight.

Of course, we recommend doing this without shoes on. Simple techniques like this can help make your mattress more comfortable quickly.

Is It Worth Waiting To Adjust To My Memory Foam Mattress?

Although every person’s mattress preferences are slightly different, most people find that it is worth a month or two of initial discomfort to adjust to their memory foam mattress and then have years of great sleep.

This is because memory foam has advantages that traditional mattresses simply can not compete with.

One of the main ones is that memory foam mattresses tend to help support the back properly, while innerspring mattresses can put all sorts of unwanted pressure on the back and cause pain.

Another important feature is that memory foam mattresses are great because they do not attract dust mites the same way traditional mattresses do, because they are not made out of cotton.

What Should I Do If I Don’t Adjust To The Mattress?

If you don’t adjust find the mattress becoming any more comfortable after at least 30 days, there are a few things you can do. The first, of course, is to return the mattress.

Many memory foam mattress companies offer a free 60, 90, or even 180 day trial period where you can return the mattress free of charge.

If you think the mattress has potential but isn’t quite comfortable enough yet, consider adding a mattress pad or a mattress protector to add the desired softness or firmness to your mattress.


When it comes to memory foam, the name of the game is patience. Many people will find that they start to adjust to their memory foam mattress at about the 30-day mark, with some people taking longer and some people taking less time to get comfortable.

At the end of the day, each individual is different, so do not worry if you aren’t extremely pleased with your mattress within 30 days.

We hope you have found this article informative, and we hope you enjoy your memory foam mattress and get many years of great sleep from it.
