A "comfort layer" refers to a specific layer in a mattress designed to provide cushioning and support for the body. This layer is typically made from materials like memory foam, latex, or polyfoam, which help to relieve pressure points and enhance overall sleep quality. The comfort layer plays a crucial role in how a mattress feels, influencing factors such as softness, firmness, and temperature regulation. In addition to mattresses, the concept of a comfort layer can also apply to other products, such as pillows and bedding. These items often incorporate similar materials to enhance comfort and support during sleep. Understanding the function of the comfort layer can help consumers make informed choices when selecting sleep products.
