Bringing home a new mattress is exciting, but it doesn’t always feel perfect right away. If your new bed feels firmer or less comfortable than expected, don’t worry. This is a normal part of the mattress break-in process. With a few simple steps and a little patience, you can help your mattress (and your body) adjust for a better night’s sleep.
What is the mattress break-in period?
The mattress break-in period is the time it takes for your new mattress to soften and conform to your body. Materials like memory foam, latex, and hybrid layers often need several weeks of regular use before they reach their optimal comfort level. During this time, both the mattress and your body are adjusting to each other.
How long does it take to break in a mattress?
Wondering how long to break in a mattress? Most mattresses break in within 30 to 60 days, but the exact timeline depends on the type of mattress:
- Memory foam mattresses, like The Casper Mattress, can take anywhere from 30 to 60 days to break in
- Hybrid mattresses, like the Casper Original Hybrid Mattress, can take anywhere from 30 to 90 days to break in
- Innerspring mattresses take around 30 days to break in
Casper offers a 100-night risk-free sleep trial on all mattresses, giving you over three months to test out and adjust to your new mattress. Shop Casper Mattresses.
Why do mattresses need to be broken in?
New mattresses are built to last, which often means they start out firmer than expected. Materials are tightly packed and may feel stiff or unyielding at first. That’s why breaking in your mattress is so important. The mattress break-in process includes the following:
- Loosen and soften the materials
- Allow the bed to better contour to your body
- Air out any new-mattress odours
The above steps must be taken to ensure you experience the true comfort and support of your new bed.
Tips to break in a mattress
While patience is important, there are a few ways to help you adjust to your new mattress faster:
1. Sleep on it consistently
The most effective way to break in your mattress is to use it every night. Your body weight and movement help soften the materials and encourage the mattress to adapt to your shape. Even if it feels a bit uncomfortable at first, try to avoid switching back to your old bed.
2. Spend extra time on your mattress
Don’t just limit your mattress use to sleeping hours. Try sitting, reading, or relaxing on your bed during the day. The more time you spend on it, the faster it will adjust to your body.
3. Apply gentle pressure
For memory foam mattresses, you can gently walk or crawl on the surface to help loosen up the materials. Placing heavy objects (like books) on different areas for short periods can also help. Be careful not to damage the mattress by applying too much force or focusing weight in one spot.
4. Adjust the temperature of your bedroom
Some mattress materials, such as memory foam, respond to heat. Therefore, a slightly warmer room can make the foam more pliable and speed up the break-in process. Just be mindful of your own comfort and sleep quality.
5. Rotate your mattress
Rotating your mattress 180 degrees every couple of weeks during the first few months can help ensure even wear and a more uniform feel. Learn more about mattress maintenance in our Ultimate Mattress Care Guide.
6. Consider using a mattress topper
If the mattress feels too firm, consider using a mattress topper for extra cushioning during the break-in period. This can make the transition more comfortable without interfering with the break-in process. Shop the Casper Comfy Mattress Topper.
7. Check your bed’s foundation
A supportive, properly sized foundation helps your mattress break in evenly and prevents sagging. Make sure your bed frame or base is compatible and in good condition. Shop Casper Bed Frames and Adjustable Bases.
