How to get
The By Sealy Slumber Firm Mattress is built for sleepers who like a steadier, more supportive feel. Created through a partnership between Sealy and our Sleep Experts®, it balances reliable support with comfort you can settle into night after night.
Individually wrapped coils respond to the natural shape of your body for ultra responsive support and reduced motion transfer. Above the coils, gel foam layers add contouring comfort for pressure relief and are designed to help regulate body temperature so you can sleep cooler.
It also arrives as a mattress in a box for convenient setup. Unbox, unroll, then allow up to 72 hours for the mattress to fully expand and reach its intended feel. With Mattress Firm, we make sleep easy.
