Wayfair Sleep 135 Medium Cooling Gel Memory Foam Mattress

This cooling memory foam mattress updates your bed with support and just the right temperature. It's made from medium-firm memory foam designed to mold to the shape of your body for a customized fit that soothes achy joints. The tight top has a layer crafted from an ultra-cooling gel, which keeps you from overheating at night. We love that it's 13.5'' thick for a plush feel, and it comes conveniently rolled in a box for easy shipping. Simply unbox, and unroll, and it expands to its original shape within 72 hours.
