A mattress provides side support that reduces the likelihood that a person will accidentally roll off and also provides increased comfort to a person sitting on the side of the mattress. The mattress includes a top layer, a bottom layer and a buffer layer between the top and bottom layers. A pair of support members are placed in corresponding cavities near the opposite sides of the top layer. The support members are firmer than the top layer and are arranged to support the top layer and provide reduced compression of the mattress when a weight is placed on the upper surface of the top layer near the support members.
