Product Description:
Power your sleep with the comfort you can count on with the Major S-Brand Posturepedic Hybrid 12" King Mattress. This adaptive hybrid mattress provides the perfect balance of luxurious comfort and optimal support to help you get the blissful night of sleep you deserve. With layers of comfort, the Air Gel Foam paired with the fabric-encased coils delivers a flexible, breathable comfort, conforming support, and reduced motion transfer with a medium-firm gel mattress feel. We were the first ever to reinforce the center third area of the mattress which targets the heaviest part of your body, allowing you to stay well-supported while you sleep. The ultra-durable coil system reinforces the edge of the mattress to offer more sleeping space while preventing sagging over time and increasing flexibility when paired with an adjustable base. The mattress is covered by a durable, soft knit fabric featuring moisture-wicking to help you stay cool and cozy and antibacterial Surface-Guard Technology for superior protection.

SUPPORTIVE: Incorporates a support mechanism designed to adapt to your body's contours, promoting balanced weight distribution for optimal alignment.
