The mattress core is covered by several soft materials which provide cushioning and comfort. Some manufacturers call the mattress core “the Support Layer" and the cushioning materials “the Comfort Layer". The upholstery used in the comfort layer is a way to measure the quality of the mattress. You can also judge the quality by the number and gauge of the coils.
The "Comfort Layer" can be divided into three sub-layers:
This layer separates the mattress core from the upholstery, and it is usually made of fibre or mesh, to keep the middle upholstery in place.
This layer is made from all types of materials on top of the insulator and beneath the quilt. Regular foam, visco-elastic foam, felt, polyester fibres, cotton fibres, egg-crate foam, non-woven fibre pads, all give maximum comfort while you sleep.
The quilt is the top layer of the mattress and can be made of light foam or fibres that are stitched to the underside of the ticking. The quilt can be firm, soft, or plush. It provides the immediate soft texture that you feel when you’re lying on the mattress.
The ticking is the protective fabric cover, which encases the support and comfort layers of the mattress. It is usually made to match the bed base and comes in a wide variety of colours and styles. Most ticking is made of synthetic fibres like polyester, latex and acrylic, eg. Kaymed pocket 1600 or Myers Laytex Supreme But it can also be made of natural materials such as cotton, silk and wool as in the Respapedic mattress from Respa.
