Treat yourself to generous comfort with this plush mattress topper. Made from polyester, it features a quilted top with a simple baffled box design that prevents the filling from shifting unevenly after prolonged use. We love that it sports a generous 3'' thickness, which is ideal for softening thinner or more firm mattresses for those who like a softer surface. Plus, its cooling technology keeps you from getting overheated. To clean, we recommend machine washing cold with similar colors. Tumble dry low; remove promptly. Do not dry clean.
