No matter how much we may wish it, there comes a time when your old mattress needs to be replaced. Over time it could sag due to multiple years of carrying your body and even break down. However, when you finally get a new mattress, it takes a bit of time for your body to adjust to it. 

So, how long does it take your body to get used to a new mattress? It may take anywhere from one to two months for your body to get used to a new mattress.

If you want to know why it takes that long and what you can do to perhaps speed up the process, read on.

Factors That Impact How Long It Takes To Get Used To A New Mattress


Receiving a new mattress is exciting. However, the initial joy could turn into concern after you unwrap the protective packaging from the mattress, as you may quickly become aware of an odor. 

The odor of a new mattress is the result of a process called off-gassing. Off-gassing occurs because of the volatile organic compounds (VOCs) that are produced during manufacturing. When you unwrap the mattress, the scent of these VOCs escape the plastic packaging and take a while to go away. 

Don’t worry; these won’t cause you any harm. However, it might be hard to sleep on the mattress until the smell goes away. 


During your first night sleeping on the new mattress, you may find that it is very thick or tough. That does not indicate a problem. Manufacturers of mattresses nowadays purposely make the mattress thicker than how they’ve been made historically.

New sheets

Depending on the size of mattress you get, your old sheets that fit perfectly on your old mattress may not fit properly on the new one. So, you may have to purchase a new set of sheets, which can take a bit of getting used to.


Your first day after sleeping on your new mattress, you may suffer some soreness. The reason for the soreness is that your body had become used to how your old mattress supported it. However, due to its age and its deterioration over time, the old mattress wasn’t supporting your body properly. 

The new mattress is now supporting your body properly, but it will still feel uncomfortable. It’s up to you to become familiar with the new orientation. Getting used to this aspect of the mattress won’t take much time at all.

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

One of the most popular materials used to make mattresses is memory foam. As is the case with mattresses in general, one can ask, “How long does it take to get used to a new memory foam mattress?” Memory foam is a high-density material. Because of that, it could take as many as eight weeks before it is properly broken in.

Memory foam mattresses require a longer break-in period because they feature layers of foam stacked one on top of the other. This design is meant to support your weight and conform the mattress to your body.

However, they have a denser feel than other materials. A memory foam mattress feels denser because there is more material per cubic foot. More time is needed for the foam cells to open up and for the mattress material to loosen and stretch.

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

Many people claim that the Purple Mattress is the healthiest mattress around. Its key component is polyurethane foam. It is this material that makes it healthier than other mattresses. The mattress as a whole features three layers, which total 9.5-inches.

The first layer is 2-inches of Hyper-elastic polymer™ Smart-Comfort Grid. It offers great support, releases pressure, and allows airflow that helps keep it temperature neutral. The second layer is made of 3.5-inches and 1.8-pounds of dense polyurethane foam. The third layer is 4-inches and 2-pounds of dense polyurethane foam.

So, how long does it take to get used to a purple mattress? It takes about 21 days. 

But people who have slept on it claim that you feel the difference after about 2-weeks. One user says, “We’ve been on it for about two weeks now, and I’m finding myself sleeping better and better every night.”

The reason it takes as much as 21 days to get used to it is that your previous mattress didn’t shape naturally to your body. Through the years, your body has grown familiar to improper support and has had to compensate for it.

So, when you sleep on a purple mattress, your body is not used to the proper support it gets from it. So, as you sleep on it for the adjustment period of 21-days, your body slowly unwinds and returns to a better-balanced state.

How To Break In A New Mattress

How you break in your mattress may depend on its style. 

For example, the traditional innerspring mattress features a soft material that surrounds metal coils and springs. The break-in time may be shorter because these mattresses are sold with pillow-top cushioning. It is advised that you flip and rotate the mattress every three months. This avoids sagging in the portion of the mattress where you sleep.

Taking the time to flip and rotate the mattress will distribute your body weight across the coils and properly breaks in the whole bed.

Breaking in an innerspring mattress can take up to four weeks, though the exact amount of time depends on how often you’re laying on it. Someone who sleeps for 9 hours per night is going to break in a mattress faster than someone who sleeps for 7 hours per night. 

Allow a memory foam mattress to decompress on itself several days after it’s been delivered. Lie on it, and crawl, walk and roll on it several times a day to make it softer.

To assure that the breaking in period is successful, don’t cover your memory foam mattress with a mattress topper. It limits decompression because it protects the mattress from your body weight and temperature.

Experiment with your bedroom’s temperature to assist a memory foam mattress in adjusting its firmness and flexibility. You probably aren’t aware that memory foam mattresses are sensitive to temperature variations. Well, it’s true; they react instantaneously to severe body heat, which makes the foam more flexible.

When you set your bedroom’s temperature cooler, memory foam mattresses become firmer and feel harder. So experiment with room temperature to adjust the softness and comfort of the mattress.

It takes less time to break in a latex mattress than other styles of mattress. Its feel won’t be significantly different once the break-in period is over.

Latex foam mattresses are made from natural, synthetic, or blended materials that offer great support. They are sold in a variety of firmness levels. They are also offered as hybrids and made from a combination of latex foam, memory foam, and spring support.

Soft and supportive, these mattresses take less time to break-in, which is from three days to two weeks. This is because air is able to settle in latex foam synthetics, causing the material to break in quicker.

A Tempurpedic Cloud Mattress is favored by many because of its softness and comfort. It is reported that it takes about two weeks to break in. At first, it may feel too hard. However, the Tempur cells will open during the breaking in and quickly adjust to your weight and to temperature changes. A new Tempurpedic will release an insignificant odor that will dissipate after a few weeks of use.

Breaking in a Tempurpedic Mattress involves:

  • Spending more time in bed
  • Extra movement when on the mattress to get the Tempur cells to open completely
  • Allowing the Tempur cells to breathe so that the mattress can compensate for the change in temperature and body weight

Applying intense pressure on the mattress won’t cause problems. It is designed to return to its original shape, whatever happens.

Experiment with the temperature settings of your bedroom during the breaking in process. For example, set the temperature of your bedroom at 65°F, and the Tempurpedic mattress will normally be firmer. However, when you lie on it, it adjusts to your body temperature and offers a softer feel and stronger support.

There are things you can do to expedite the break in process. They include:

  • Sleeping on the mattress from day one.
  • Letting the mattress breathe.
  • Using weights
  • Warming it up

You should also spend as much time on the mattress as possible. Read, watch television, and do work on it.

Letting The Mattress Breathe

When the mattress is delivered and put into your bedroom, don’t immediately put sheets, blanket, and bedspread on it. Instead, allow the material to breathe. This will introduce oxygen into the material and help to soften the mattress up quickly.

Using Weights

Put weight on the mattress. If you get a new memory foam mattress, then it is okay to walk on it. If you get an innerspring mattress, it’s okay to move across it with your hands and feet so that you don’t shift or break the springs. 

Also, it’s okay to put heavy objects on the mattress. This can include books, boxes, or any other weighty object. Move the weighted items around the top of the mattress. This will enhance the flexibility of the material quicker. 

Warming It Up

It will help to raise the temperature of your bedroom if you have a memory foam mattress. This will make the mattress feel softer within a shorter period of time.

Be sure that your new mattress has firm and strong support. Without a strong foundation, it will sag and degrade and could cause the manufacturer to void the warranty.
