Enjoy the benefits of a premium mattress made to the standards of fine hotels. The Serta® Lux Suite Cushion Firm Mattress combines Serta’s hotel-quality innerspring coil system with the enhanced comfort of Cool Action™ Gel Memory Foam. This innovative memory foam is designed to deliver excellent pressure-point relief and targeted support. It also reduces heat build-up at the surface, to promote the ideal temperature for a restful night's sleep. Plus, layers of Serta Comfort XD™ Foam and PillowSoft™ Foam give this mattress its plush, cradling feel.
