This 3" Gel Memory Foam Topper with a Breathable Cover is an affordable way to make any mattress that feels too firm more comfortable. This topper features an extra-plush profile, perfect for side sleepers and those that prefer to really sink into their bed. Plus, the premium memory foam is infused with gel to help pull heat away from your body to create a cooler and more comfortable sleep environment. The included cover helps add an extra soft and breathable layer to your topper while also providing a little protection. The cover is machine washable so you can keep your topper looking and smelling fresh.
