Product Details

The Serta Perfect Sleeper is the only official mattress of the National Sleep Foundation, designed to help solve five common sleep problems – tossing & turning, lack of support, sleeping too hot/too cold, partner disturbance, and mattress roll-off or sag.

The Luxury Firm mattress is made with Serta’s exclusive DuoSense Hybrid Coil Support System, an exclusive support system that works to promote proper back support and undisturbed sleep by balancing comfort and support across the entire sleep surface.  Plus, a custom designed version of our Total Edge Foam Encasement makes the mattress compatible with an adjustable foundation and helps to prevent roll-off or sag at the edge of the mattress.

This mattress also features Serta’s SmartSurface, an exclusive design that works to provide pressure relieving comfort and a balanced sleep temperature right at the sleep surface.  First, our Cool Balance fabric technology helps regulate temperature swings that can disrupt your sleep.  Then a plush layer of anti-microbial BodyLoft fiber provides enhanced cushioning while wicking away moisture that can cause uncomfortable heat buildup.

The Luxury Firm also features Serta’s Cool Twist Gel Memory Foam, an exclusive liquid gel-enhanced memory foam designed to help move heat away from your body, helping to promote a balanced sleep temperature.  This material also gently conforms to the body to provide enhanced pressure relieving comfort.
