    What I claim as my invention is:1. A resilient mattress for support of the body of a person lying thereon in any natural position, the mattress being of uniform thickness at its end portions for support of the head and lower limbs of the body of a person lying upon the mattress, a recess in the bottom face of the mattress and having a flat inner face and located intermediately of the length of the mattress and forming a reduced thickness portion of the mattress for support of the area between the shoulders and hips of the body of a person lying upon the mattress, a rigid flat top supporting member of substantially the same area as the mattress and upon which the mattress rests, and a rigid flat top rib protruding from the top of the supporting member for reception within the recess, the rib being of the same dimensions as the recess and supporting the reduced thickness portion of the mattress above the recess.

    3,083,380 MATTRESSES Harry M. Adler, 421 Whitney Ave., Hamilton, Ontario, Canada Filed Dec. 26,1961, Ser. No. 161,838 5 2 Claims. (CL 5—345) My invention relates to improvements in mattresses and the object of the invention is to provide a mattress arranged for combination with a supporting member 10 therefor, wherein such combination and arrangement provides a mattress having a central portion furnishing a substantially firm support for the heaviest part of the body of a person lying thereon, the upper and lower end portions of the mattress supporting the head and limbs being soft in relation to its central portion. The foregoing object is achieved by providing a flat top mattress of standard thickness at its end portions and formed with a reduced thickness central portion for support of the heaviest part of the body and defined by qo a transverse channel having a flat top face and extending from side to side of the under central portion of the mattress; the supporting member upon which the mattress rests being formed with a flat top platform rib of the same size and shape as the mattress channel to be 25 received therein and supporting of the thinner central portion of the mattress. With the foregoing and other objectives in view, as shall be apparent as the specification proceeds, my invention consists of a mattress and supporting member there- 3θ for constructed and arranged all as hereinafter more particularly described, and illustrated in the accompanying drawing, in which:FIG. 1 is an expanded perspective view of the mattress and its supporting member, and 35 FIG. 2 a side view, partly in section of the mattress resting upon its supporting member. The mattress 2 is provided in any of the standard sizes and is preferably of standard uniform thickness in its head and end portions. The bottom portion of the mattress is formed with a recess or transverse channel 3 extending from side to side of the mattress and having a flat top face 4, the channel being positioned intermediately of the length of the mattress to define in its width a substantially firm 45 portion 5 for support of the heaviest part of the body of 4 a person lying upon the mattress. The lower and upper limbs and head supporting portions 6 and 7 of the mattress are of any desired softness. The mattress supporting member may be of any desired ,construction, either rigid or semi-rigid, and in the drawing I have shown it comprising a flat top hollow box-like structure 8, if necessary, suitably reinforced, as by ribs 9, and formed of any suitable material such as moulded hard plastic or plywood. The member is of substantially rr the same length and width as the mattress it supports and 00 is formed upon its top face with a flat top transverse platform rib 10 of the same size and shape and in the same position as the mattress channel 3 to sungly fit
