Dig Deep Into Comfort: What’s Inside Your Mattress?

A variety of materials are used in mattresses to enhance comfort and durability. The more familiar you are with these components, the better you can determine your priorities and preferences in your sleep experience.  Read on for a look into the layers that you’ll find in most mattresses.


A durable, tightly woven fabric (often cotton, polyester or linen) used to cover mattresses and pillows. It sometimes features a twill weave.


The top cushioning layer of a mattress and part of the mattress cover itself. Its purpose is to add softness to the comfort layer. It also helps the mattress breath, regulate temperature and serves as a fire retardant.

Middle Padding

Just below the quilted top layer, this layer is usually made of foam in order to enhance comfort. Another layer is cotton batting with varying thickness throughout the mattress in order to provide firmer support in certain areas.

Insulated Padding

Used to protect the sleeper from feeling the coil springs, and to prevent the coils from damaging the mattress. Common fabric materials used for this padding are matted fabric and plastic fibers.

Extra Support

Dense foam along the edges of the mattress provide firm support when someone sits on the edge of the bed.


A key component to mattress support, coils are springs used in the mattress, primarily in the support (core) layer. The lower the gauge of the coil, the thicker it is. A higher coil count and the way the coils are constructed have a large impact on comfort and support.

Box Spring

A type of foundation that provides additional support for a mattress, typically consisting of a wooden frame containing springs, covered in cloth.
