A pillow top mattress is a type of mattress that has an additional layer of padding sewn into the top. This padding, which resembles a "pillow, " adds extra cushioning and comfort, providing a softer feel compared to standard mattresses. The pillow top layer is typically filled with materials such as memory foam, fiberfill, or down alternative. It enhances the sleeping surface, making it more plush and comfortable. Pillow top mattresses are popular for those who enjoy a softer sleep experience, but they can vary in thickness and firmness, so it’s important to test one in-store or read reviews before purchasing to ensure it meets your comfort preferences.
