An electric mattress pad is a bedding accessory designed to provide warmth and comfort while sleeping. It features built-in heating elements that can be adjusted to different temperature settings, allowing users to customize their sleeping environment. These pads are typically placed on top of the mattress and are compatible with various bed sizes. Many electric mattress pads come with safety features such as automatic shut-off timers and overheat protection to ensure safe usage. They are often made from soft, washable materials, making them easy to maintain. Ideal for cold climates, they can help improve sleep quality by keeping the bed warm and cozy.
