Serta Perfect Sleeper Ravensworth Firm Mattress

The Serta Perfect Sleeper is the Only Official Mattress of the National Sleep Foundation (NSF), designed with input from the NSF to help solve 5 common sleep problems. Every new Serta Perfect Sleeper mattress comes with the National Sleep Foundation’s exclusive Guide to Sleeping Well, an informative booklet which provides tips, suggestions, and resources to help you get the most from your new Perfect Sleeper mattress each and every night.

Serta’s Exclusive SmartSurface Cover

Exclusive design works to provide pressure relieving comfort and a balanced sleeping temperature right at the sleep surface. Cool Balance fabric technology helps regulate temperature swings that can disrupt sleep. Anti-Microbial Body Loft fiber provides enhanced cushioning while wicking away moisture.

Free Flex Innerspring with Custom Support and Total Edge Foam Encasement

Patented and exclusive TrueSense coil design helps promote undisturbed sleep by adjusting to support you while reducing motion transfer. Custom Support promotes proper back support with up to 25% more support in the center third of the innerspring, where you need it most. Provides the flexibility needed to use the mattress with a regular or adjustable foundation, while also helping to prevent roll-off or sag at the edge of the mattress.

Cool Twist Gel Memory Foam

Exclusive liquid gel-enhanced memory foam designed to help move heat away from your body, helping to promote a balanced sleep temperature.

Comfort XD Foam

Extra deep layer of soft yet supportive foam that gently cradles the body to help provide enhanced pressure relieving comfort near the sleep surface.

Specifications

Comfort Level

Firm

The firm mattress offers classic tailoring with fewer plush comfort layers at the sleep surface than our other models, so you will feel the support system more prominently when you lie down.
