Avenco medium hybrid mattress combines the best of both worlds : the comfort of memory foam and the support of innerspring coils. The top layer of the hybrid mattress is made with high-quality memory foam that conforms to your body's natural curves, providing unparalleled comfort and pressure relief. Beneath the memory foam layer, there are individually wrapped innerspring coils that provide superior support and help to distribute your weight evenly across the mattress. In addition to memory foam and innerspring coil, the mixed mattress uses 3D soft knitted fabric, whose surface is breathable and moisture absorption,providing unparalleled comfort for a restful night's sleep.
