This adaptable mattress topper offers a choice between a firm or soft feeling, extending the life of your mattress. It features a breathable Airgocell® foam layer for a soft surface that absorbs and evaporates sweat, keeping you cool and dry. Alternatively, the HRX ZeroGravity layer provides firmer support. The UltraDry cover wicks away heat, preventing overheating, and is removable and washable for a fresh feel. The topper is 100% vegan and cruelty-free. You can flip the topper to suit your firmness preference, ensuring added comfort and support while you sleep.
