How to Flatten Out a Pillow Top Mattress

Pillow top mattresses have an extra layer of filling and padding attached to the top of the mattress. This supplementary material adds a layer of softness and, for some sleepers, a feeling of reduced pressure on certain parts of the body. Like all mattresses, pillow tops require a break-in period and regular use to flatten out and conform to your body. You can flatten out and break in the entire pillow top over time.

Pillow tops flatten out over time.

Step 1

Position yourself on one side of the bed.

Step 2

Sleep in this same spot of the mattress nightly for a few weeks.

Step 3

Position yourself in the center of the mattress. Sleep in this spot nightly for a few weeks.

Step 4

Repeat steps 2 and 3 on the other side of the bed nightly for a few weeks.

Step 5

Wait a few months and then rotate the mattress. Remove all bedding, lift the mattress up and rotate so the top of the mattress is at the foot of the bed. Repeat this every few months.

Step 6

Check if your pillow top mattress is double-sided -- if it has a pillow top on both the top and bottom sides. If so, flip your mattress every few months and repeat steps 1 through 5 on the other side of the mattress when flipped.


  • Do not flip one-sided pillow top mattresses, as doing this may damage the pillow top not designed to be face down on the box spring.
  • Do not put heavy objects on the mattress except your body.
  • Do not jump on the mattress, hit the mattress hard or pile things on top of the mattress.
