Claim:
A mattress, comprising: a top cover layer; a bottom cover layer; a cavity between said top cover layer and said bottom cover layer; a spring array comprising a plurality of grid supports and a plurality of springs; a frame layer that encloses a plurality of sides of said spring array; and a removable mattress cover; wherein said top cover layer includes a foam layer; wherein said plurality of springs comprise a plurality of support plates, a plurality of spring arms, and a mid-base; wherein a lower end of said plurality of spring arms is connected to said mid-base in a straight and in an angular position with respect to said mid-base; wherein an upper end of said plurality of spring arms is connected to said support plate; wherein said base attaches to one of said plurality of grid supports such that said support plate is distal to said plurality of grid supports; wherein said plurality of springs annularly spread when pressure is applied to said plurality of springs such that said spring arms deform downward and outward, and the support plate deforms outward; wherein said plurality of springs are attached to said plurality of grid supports at the mid-base of the plurality of springs; wherein said plurality of grid supports are connected to each other; wherein said connected grid supports are inserted into said cavity between said top cover layer and bottom cover layer; wherein said plurality of springs are made of plastic; wherein said plurality of springs show varying spring flexibility depending on where they are located on said connected grid supports; wherein said mattress is divided into a plurality of recumbence areas, and said plurality of recumbence areas exhibit differing spring flexibility; wherein said plurality of recumbence areas are separated by flanges so that said plurality of recumbence areas provide independent support and flex characteristics; and wherein said plurality of recumbence areas are divided into a plurality of subdivisions, and said plurality of subdivisions exhibit varying spring flexibility.
