This hybrid memory foam mattress combines modern gel memory foam with classic pocket coils for support. It's made up of memory foam layers of various thicknesses surrounding the coils. The construction is designed to relieve pressure in your body while you sleep while still being breathable, keeping you from overheating. We love that this mattress has a 14'' plush thickness, and it comes conveniently rolled in a box for easy shipping. Simply unbox, unroll, and give it some time to expand to its original shape. Plus, it has a 10-year warranty.
