A pillow-top mattress is a type of mattress that features an additional layer of cushioning sewn onto the top. This layer is typically made from materials like memory foam, latex, or polyfoam, providing extra softness and comfort. Pillow-tops are designed to enhance the sleeping experience by offering better pressure relief and support for the body. These mattresses come in various sizes and firmness levels, catering to different sleep preferences. They are popular among those who enjoy a plush feel while still benefiting from the support of a traditional innerspring mattress or hybrid mattress. Regular maintenance, such as rotating the mattress, can help prolong its lifespan.
