Cooling Gel Mattress Topper Queen: The ice cooling gel memory foam mattress topper for queen-size mattresses is a mattress cover made of cooling gel. These toppers actively control temperature and dissipate heat with cooling gel-infused foam or gel beads. People can enjoy a peaceful and comfortable night's sleep on their queen-size mattress thanks to gel technology that helps create a cooler sleeping environment. The topper's permeable fabric improves airflow and adds to the bed's cooling effect.
