A mattress pad is a thin layer of cushioning that sits on top of a mattress. It is designed to provide extra comfort and support while sleeping. Mattress pads can help protect the mattress from spills, stains, and wear, extending its lifespan. They come in various materials, including memory foam, cotton, and polyester, catering to different preferences. In addition to comfort, a mattress pad can also regulate temperature, keeping you cooler in summer and warmer in winter. Many mattress pads are machine washable, making them easy to maintain. They are available in various sizes to fit different mattress dimensions, ensuring a snug fit.
