A satisfying night’s sleep starts with the right kind of support — which is why the Sealy Posturepedic king mattress is available in a memory foam or hybrid models.  The Memory Foam mattress is best for sleepers who want motion isolation, contouring and conforming support, and a medium, modern feel. The Hybrid mattress has a mixture of Foam + Springs for sleepers who want an extra bounce, added edge support, and a medium, classic feel. These adaptive mattresses provides the perfect balance of luxurious comfort and optimal support to help you get the blissful night of sleep you deserve. The memory foam model has a combination of ComfortSense Gel Memory Foam paired with SealyCool Gel Foam and SealySupport Gel Foam that delivers a flexible, breathable, and conforming supportive mattress. It also gives you reduced motion transfer with a medium-firm feel so you sleep well all night long. 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. Originally developed by NASA in the 1960s for use in aircraft seating, memory foam technology was later adapted for bedding, revolutionizing the industry. Sealy CertiPUR-US® certified memory foam responds to heat and pressure, aligning the spine, neck, and hips to distribute weight, delivering custom body-hugging support, and providing unmatched comfort by relieving pressure. Additionally, memory foam minimizes motion transfer, making it ideal for individuals who share a bed with a restless partner or pet. The hybrid model combines the qualities of innerspring and memory foam mattresses to deliver best-of-both-worlds comfort. Sealy hybrid mattresses come with carefully engineered encased coils that help stabilize and support your body while you sleep, while specialty foams conform and cushion.  Our hybrid models are designed to provide pressure relief and a reduction in motion transfer, but partners will feel more movement than memory foam. Due to the spring composition, moving around on the bed is easier on hybrid models and edge support is stronger too.  The easy-care knit cover features cool-to-the-touch fibers and Surface-Guard Technology™ to help keep your mattress protected from stains and odors caused by common allergens. Additional coils positioned toward the edges of your mattress provide more useable sleeping surface and improved durability from edge to edge. Adaptive memory foam hugs your body to provide a soft and comfortable sleeping surface, and hundreds of individually wrapped coils respond to your body to provide support and pressure relief.  Memory Foam Features: SealySupport Gel Memory Foam Delivers Foundational Support and Reduces Motion Transfer SealyCool Gel Foam Promotes a Cooling Environment with Cushioning Comfort SealyChill Cover with Spun, Cool-to-the-Touch Fibers that Deliver Refreshing Comfort Surface-Guard Technology Protects Mattress from Bacteria, Odors and Staining Hybrid Features: ComfortLoft Cover with SealyChill Fibers for a Cooler Feel and Surface-Guard Technology to Help Protect Against Odors and Staining SealyCool Gel Foam: Cushioning, Cooling Gel Foam DuraFlex Coil Edge: Additional Coils Provide an Edge-to-Edge Sleeping Surface CertiPUR-US Certified: All Sealy Foam Meets CertiPUR-US Standards Having trouble deciding which is best for you?  The Memory Foam mattress is best for sleepers who want motion isolation, conforming support, and a medium, modern feel with less bounce.
