The various types of mattresses are: spring coil mattresses, air mattresses, and foam mattresses. The spring mattresses have a foundation, inner spring coils and the upholstery layer. The inner spring coils are made from steel coil springs and the gauge (thickness) of the coil determines the firmness or support that the mattress gives to the sleeper’s body. The air mattresses have air chambers to replace the springs for providing support. In case of foam mattresses, the springs are replaced with shape-conforming latex. Viscoelastic memory foam is also used in some cases.
