Ultra firm and ultra-supportive, the Posturepedic Antiguan Skys premium materials and innovative design allow it to deliver your most restorative nights sleep yet. Designed with your comfort in mind from the very first touch, this firm mattresss soft knit cover utilizes moisture wicking technology to keep you cool and comfortable as you sleep. At the core of the mattress, innovative Sealy Embrace Plus coils are densely arranged and individually encased to deliver targeted support precisely where you need it. Enhancing the premium coil system is the CoreSupport system, which places a reinforced band of gel infused memory foam at the center third of the mattress where the majority of your body weight is located as you rest. A layer of firm MarveLux foam at the sleep surface hugs the body, providing additional support and comfort, while the SolidEdge HD support system reinforces the mattress edges for a larger usable sleep surface. 10 Year Non-Prorated Warranty.
