Stay Cool and Comfortable All Night Long

The Serta Perfect Sleeper Pillowtop King Mattress features Cool Twist® Gel Memory Foam that creates a comfortable sleeping environment. It's designed to keep your mattress fresh and reduce the buildup of heat at the surface for hours of quality sleep. Seven inches of Serta's 825 Edition Custom Support Innerspring provides unparalleled support and reduces motion transfer when you and your partner turn over.

Is a cushion-firm mattress the right choice for me?

If you like your mattress firm with a little cushion on top, cushion-firm is a perfect choice. Combination sleepers who sleep in two or more positions through the night might find cushion-firm to be a good choice as it provides the best flexibility and comfort across a selection of positions.

Can I flip the Serta Perfect Sleeper Pillowtop Mattress over?

Since this mattress features a pillowtop on one side, it cannot be flipped over. We recommend rotating your mattress every 1-2 months to reduce wear and extend the life of your mattress.

Serta Perfect Sleeper Luxury CollectionOfficial mattress of the National Sleep Foundation, the Serta Perfect Sleeper model addresses five common sleep problems. Comfort XD™ Foam provides pressure-point relief, which helps prevent tossing and turning. Serta’s Custom Support® innerspring offers a body-cradling feel and outstanding support while minimizing motion transfer. To ensure a comfortable sleep temperature, Cool Twist® Gel Memory Foam reduces the build-up of heat at the surface. Best Edge® Foam Encasement helps reduce edge roll-off, extending the sleep surface.
