Yes, you can speed up the softening process of a new mattress by walking on it, using body heat, and performing targeted pressure exercises. Most new mattresses, especially memory foam, need a break in period of 30 to 90 days. The right techniques can make it feel noticeably softer in just a few days to a week.
New mattresses feel firmer than expected because the foam layers or coil support systems are fresh from the factory. Memory foam and polyfoam rely on temperature and repeated compression to relax and conform to your body. This is not a defect. It is how the materials are designed to work. The top comfort layers need time to soften and contour naturally.
For foam mattresses, the cells in the foam are fully expanded but still stiff. Body heat and pressure break down the foam’s initial resistance. For hybrid and innerspring models, the quilting and padding layers are tight and need a break in period to settle. The same principle applies to latex, though latex softens less dramatically than memory foam.
Before trying to soften your mattress, confirm that it is actually too firm and not just new. Use these checks:
These steps can accelerate the softening process without damaging your mattress or voiding the warranty.
If after 30 days the mattress still feels too firm and these steps have not helped, it may not be the right firmness level for you. Check the return policy. Many brands offer a 90 to 120 night trial. If you are within that window, consider a softer model. See our mattress buying guide for help matching firmness to sleeping position.
If you have tried the softening methods for at least 30 days and the mattress still causes pressure points, numbness, or poor sleep, it is time to consider a replacement. A mattress that is fundamentally too firm for your weight and sleeping position will not become soft enough with time. This is especially true for stomach sleepers who need a medium firm mattress and side sleepers who need a softer feel. If you are a heavier person (over 230 pounds), a firm mattress may never soften enough to relieve pressure. In that case, look for a mattress designed for heavier body types.

Most memory foam and hybrid mattresses take 30 to 90 days to reach their intended softness. The first 30 days show the most change. After that, softening slows significantly. If you use the walking and heat methods above, you can often feel a difference within the first week.
No, as long as you walk gently and evenly across the surface. Do not jump, run, or concentrate your weight on one small spot. Walking spreads the compression across the entire mattress and mimics the pressure of sleeping on it over time. Always use a clean sheet or protector between your shoes and the mattress.
Yes, it is very common. Memory foam is temperature sensitive. When it is cold or fresh from the box, the foam cells are stiff. Body heat and repeated compression soften the material over several weeks. If your mattress still feels hard after 60 days of normal use and the room is warm, it may be too firm for your needs.
