A Mattress is made up of several layers. A support layer, a comfort layer, and a cover are all included in every mattress. These layers can be made of a number of materials, all of which are intended to provide users with a supporting and pleasant sleeping surface. The fundamental component of the mattress is the support layer. This section provides the body with the support it requires and is a major factor in the mattress' firmness. The support layer is commonly made up of springs, foam, or a combination of both. The first few inches of the Mattress surface are covered by the comfort layer.
