Serta Perfect Sleeper Dunlake Luxury Firm Mattress


Additional Information

This luxury firm mattress features Serta’s DuoCore Individually Wrapped Coil System, designed with hundreds of individually wrapped coils that respond independently to the unique contours of your body while helping to isolate the movements of one partner to another.  Plus, Best Edge Foam Encasement strengthens the mattress edges and gives you more room to stretch. The model also features Serta’s Comfort Last Construction, meaning it is designed to enhance durability and is thoroughly tested beyond industry standards to resist sagging and edge roll-off.

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.
