A mattress consists of a foam body having recesses at positions corresponding to the locations of protruding portions of a patient lying on the mattress. Foam blocks can be selectively placed in portions of the recesses. An encasement member encases the foam body and includes a top foam sheet. A bloused waterproof, non-shearing, flame retardant and antibacterial top sheet forms a portion of the encasement member covering the foam sheet. A zipper in the encasement member enchances air circulation into and out of the mattress.

A mattress comprising: a first flexible and resilient body having a substantially flat top surface, said top surface having a plurality of recesses; at least one flexible and resilient second body fittable in said at least one recess and being sized and shaped such that when fitted in said at least one recess, a surface of said second body is substantially coplanar with said substantially flat top surface, a number of said second bodies being fewer than that of said recesses such that at least open of said recesses is empty; and an encasement member encasing said first and second resilient bodies, said encasement member including a waterproof and flame retardart top sheet covering said top surface, and a flexible and resilient foam sheet positioned between said top surface and said top sheet and attached to said encasement member adjacent edges of said top surface, said top sheet being dimensioned with respect to said resilient foam sheet such that said top sheet is bloused when said resilient foam sheet is laid taut on said top surface, wherein said foam sheet has a thickness, density and ILD sufficient, when a patient is lying on said mattress, to avoid a feeling of falling into said empty recess and sufficient to avoid a cookie cutter effect around said empty recess.
