The Memory-Pedic MH 4.0 Micro-Hybrid has an 11.5-inch profile that has the support of a wrapped coil innerspring and gel memory foam. The MH 4.0 top layer has 2-inches of Gel Memory Foam that conforms to the contours of your body and 1-inch of Latex-like Poly Foam that works with the gel memory foam layer to provide extra support. The conforming properties allow the spine to align properly and lessens tossing and turning through the night. Memory foam and Gel-infused memory foam layers draw heat away from the body. The 6-inch individually wrapped steel coils are encased in separate pockets so they can contour precisely to your body. High Density Foam Encasement surrounds coils to provide superior edge support. The 2.5-inch High Density Base Foam beneath the coils lessens motion transfer for sleep partners - you won’t wake when they do! The MH 4.0 is covered with a beautifully detailed stretch knit fabric and knit border that are designed to work with the memory foam layers to optimize its contouring properties.
