You need about seven to eight hours of sleep every night. This helps you, as an adult, get enough sleep for all processes that activate during this time to do their job. The mattress you sleep on has an impact on whether you sleep well – or rather toss and turn during the night. 

When you buy a new mattress, however, you may find that it is not as comfortable as you initially thought. This is quite normal, as you first need to learn how to break in a new mattress. It takes a while before the mattress will give you the comfort it was made for. In this article, we look at how new mattress break-in works, and how long it will take. 

Why Is My Mattress Feeling Harder Than It Did In-Store?

When you visit a mattress shop or display room, you will generally find that laying on top of a mattress in the store feels great. The mattress is soft and comfortable and provides you the exact benefits that the store owner claims. 

You decide to proceed with the purchase – but once the mattress arrives at your home, you find that it is hard and not as comfortable as you can remember.

Before you call the manufacturer and start complaining, take note that this is something to be expected. 

It takes some time for a new mattress break-in process to complete. When you receive the mattress, everything is still new. You need to sleep on the mattress for a while before it gains the comfort and plush feel that you experienced in the store. 

Some mattresses tend to be harder than others when they are delivered. This initial hardness can be alarming – but it should go away as you break the new mattress in. 

How To Break In A New Mattress?

You most likely want to know how long it will take to break in the mattress that just arrived at your doorstep. There isn’t a single straightforward answer that will account for every single mattress on the market. Breaking in memory foam mattress is different from breaking in a mattress that features an innerspring system, for example. 

Knowing how long it will take to break the mattress starts with identifying the type of mattress you have bought. It can take between 30 days and 90 days for the mattress to reach its full “break-in” spot. 

A memory foam mattress may reach its ideal comfort and firmness level sooner than an innerspring system. This is because the foam reacts to the heat of your body. When you sleep on the mattress every night, it will start to take the right shape sooner too.

With an innerspring mattress, the spring or coils used on the inside of the mattress may take longer while to reach the firmness level that will give you the most comfort.

It is important to also consider the mattress firmness option you chose. If you decided to buy a firm mattress, then it shouldn’t take too long to break the new mattress. A softer mattress may require some additional time for it to give you the plush feeling you desire. 

How Long Does It Take To Get Used To A New Mattress?

It is important to ask more than just how to break in a new mattress and how long this process takes. You also need to ask how long it takes to get used to a new mattress. 

Most people tend to sleep on a mattress for about one decade before they decide to buy a new one. With this in mind, it means you have grown used to how your old mattress felt. When you are used to the sleeping experience on the old mattress, the new one may feel strange to you. 

It is simply a new experience that you need to get used to. Most people find that they are able to adapt to the new mattress rather quickly. It should take much less time to get used to the mattress than the actual new mattress break-in time too. 

Simply ensure you sleep on the mattress regularly. This will ensure your body gets used to how the mattress feels. 

Break-In A Mattress Faster

There are ways to assist the break-in process of a new mattress. At the same time, you do not want to rush this process too much – this may rather end up causing damage to the mattress. 

One of the first things you can do is to not sleep on your mattress too soon. Sure, we advised you to sleep on the mattress regularly – but when it only arrives, allow about a day or two for the mattress to fully expand (if you bought a bed-in-a-box solution) and for it to breathe. Air will flow into the mattress when it is not immediately dressed with sheets. Fibers can then expand more thoroughly and become softer faster. 

Some people also find that rolling around on top of the mattress helps a little with the break-in process. When you roll on top of the mattress, you may find that the materials start to loosen up. This ensures the mattress can become comfortable and start to conform to your body’s shape faster. 

You can also decide to turn the heat setting up in your room for a few days – this can be very helpful in the winter. The heat may help to ensure the materials in the mattress soften at a faster rate. 


Buying a new mattress is a valuable investment. It allows you to improve your sleep. Once the mattress arrives, however, it may feel hard and different from the display model. This is not something to be concerned about. You should learn how to break in a new mattress. It takes up to 90 days for the mattress to break-in – during which time there are a few strategies you can use to sleep up the process.
