The Serta® Perfect Sleeper® Hillgate 3 Series Cushion Firm Pillow Top Mattress is designed to provide premium comfort at an exceptional value. This pillow top mattress contours to your body at the sleep surface. The layer of breathable, gel-enhanced Cool Twist® Gel Foam adds to the cushion firm feel and body-cradling comfort, and helps dissipate heat.

The Custom Support® Individually Wrapped Coil System balances body-hugging comfort with outstanding support for your body and Total Edge® Foam Encasement increases the edge-to-edge sleeping surface area, which helps prevents sagging and extends the life of your mattress.

Serta Perfect Sleeper CollectionOfficial mattress of the National Sleep Foundation, the Serta Perfect Sleeper model addresses five common sleep problems. Serta® Balanced Support Foam and PillowSoft® Foam layers provide pressure-point relief, which helps prevent tossing and turning. Serta’s Custom Support® Individually Wrapped Coil System provides proper support and alignment across the entire body. To ensure a comfortable sleep temperature, the Cool Twist® Gel Foam reduces the build-up of heat at the surface. Total Edge® Foam Encasement helps reduce edge roll-off, extending the sleep surface.
