Breathe new life into your bedding with this 4" mattress topper. Designed to relieve pressure and cradle you as you’re catching some Z’s, this mattress topper is made from medium-firm memory foam and features a cool blue hue. It's infused with a temperature-mediating gel, and it showcases a breathable and reversible design to improve air circulation. Designed to be slightly smaller than standard bed sizes, this hypoallergenic design fits right under your fitted sheet. This piece is not machine washable, so we recommend using a simple spot treatment.
