Feel extra coolness as you sleep on the Ashley Furniture M75711 MyGel 10" Gel Foam Twin Mattress. A thick layer of gel memory foam delivers a cooling effect along with contouring support and pressure-relieving comfort. The channel cut support foam and air flow support core allow more airflow for a soothing sleep experience. Active charcoal and green tea extract infused into MyGel keeps your mattress fresh. A luxury four-way stretch knit cover tops the mattress and provides a beautifully soft sleep surface that's quite inviting.
