Serta Perfect Sleeper Cobalt Coast Firm Mattress

The all-new, enhanced Serta Perfect Sleeper® mattress provides even better pressure-relieving comfort and support, while maintaining a balanced sleeping temperature to help promote undisturbed sleep. Inside the Perfect Sleeper, Serta’s exclusive HexCloud™ Gel Memory Foam features unique geometric cut outs designed to deliver cool, contouring pressure relief for the best sleep you’ve had in ages. All models include the 1000 Edition Custom Support™ Coil System for exceptional support and reduced motion transfer, plus Serta’s BestEdge® Foam Encasement technology, an extra-deep foam rail made to help reduce edge roll-off and extend the sleep surface. Serta Perfect Sleeper® mattresses are now made with HeiQ V-Block™ technology in the cover, which kills harmful microorganisms and prevents them from affecting the appearance and lifespan of mattresses.
