Understand Mattress Comfort Layers
The comfort layers of a mattress provide cushioning, aid in pain and pressure relief, and serve as protective buffers between you and the internal support core, or mattress core. Innerspring mattresses usually have basic top and bottom comfort layers surrounding the internal spring core, while foam and hybrid mattresses feature multiple levels of padding and foam throughout the comfort layer for additional cushioning. The comfort layer in most mattresses is a few inches thick, and consists of three distinct parts. The largest component, known as the middle upholstery, is made of soft and supportive material to provide sleeper comfort. The innermost part, the insulator, separates the middle upholstery from the core. And the topmost component, quilting, adds an extra layer of comfort for the sleeper. Today’s mattresses fall into three general comfort layer categories. Progressive models feature a thinner comfort layer that works in tandem with the mattress core to offer body-specific support. Differential mattresses have thick comfort layers that provide cushioning without the core. And zoned mattresses feature multiple comfort layers strategically placed to cushion certain areas of the body. This article will discuss some of the most common materials and construction methods used in mattress comfort layers.
