This innerspring mattress has medium-firm support with a breathable construction. It's made-up of memory foam layers of various thickness surrounding the innerspring coils. The construction is designed to relieve pressure in your body while you sleep, while still being breathable. We love that this mattress is 10'' thick, 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 and a weight capacity of 1,000 lbs.
