Fall asleep easily and stay asleep all night with this Serta Perfect Sleeper Castleview firm pillowtop king mattress set. The integrated Custom Support system uses 953 individually wrapped coils to hold your body in a comfortable position while you sleep to help encourage proper sleep posture & keep your spine aligned, ideal for minimizing stiffness & relieving back pain. The coils help isolate motion so you can move around & get out of bed without disturbing your partner. A Total Edge Foam Encasement system uses a combination of extra foam support & a durable border rod to extend the sleeping area so you can sit on the edge of the mattress & sleep through the night without rolling off the sides.

The mattress in this Serta Perfect Sleeper Castleview mattress set has layers of soft memory foam that conform to your body & help relieve pressure points so you can sleep comfortably without tossing and turning. The Cool Twist gel memory foam encourages airflow & helps disperse heat to ensure a consistently comfortable sleep temperature. Boasting a medium-firm firmness level, the mattress cradles your body while comfortably supporting your back, hips & shoulders.

This Castleview king mattress set includes two 9-inch StabL-Base box springs. The box springs provide stable, impressively durable foundations for your bed & provide consistent support to ensure efficient weight distribution & prevent mattresses from sagging over time.

Serta Perfect Sleeper 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 & turning. Serta’s Custom Support® innerspring offers a body-cradling feel & outstanding support while minimizing motion transfer. To ensure a comfortable sleep temperature, 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.
