If you want to make your bed thicker, and the bed is a little soft and comfortable to sleep... Just add one to your bed.
Firm enough to be directly on the floor and moderate elasticity to support your body.
We recommend placing it under your bed to eliminate the feeling of the bottom and keep you comfortable to sleep.
