Abstract
Abstract A mattress is made up of a central core, insulators on either side, pads of stuffing on the insulators and a cover with a zipper closure and an inner flange holding the components in place. By providing discrete components with the uniquely designed cover, untrained personnel can separate one or more components of the mattress which may require repair or replacement all to the end that mattresses need not be sent out to a factory or mattress renovator.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
244 words
A modular mattress structure made up of separable component parts including, in combination: a. a central core; and b. a cover defined by top and bottom panels of cloth-like material, each panel including a peripheral skirt about its entire perimeter and at least one panel having an annular flange secured to the inside edges of the panel where the panel connects to the skirt, the flange extending beyond the end of the skirt and including within its free extending end an inextensible cord of perimeter less than the perimeter of the panel, the free hanging ends of the skirts of the top and bottom panels having cooperating zipper closure means about a major portion of their perimeters, one portion of the skirt on the top panel being secured to a corresponding portion on the skirt of the bottom panel, the bottom panel being turned upside down relative to the top panel so that its skirt extends upwardly, whereby the top and bottom panels may be received over the top and bottom of the central core, the free extending end of the flange being received over and tucked inwardly of the central core over the entire perimeter of the core so as to secure the panels in position on the core, closure of the zipper closure means securing the cover in place to provide a mattress structure which can be disassembled by hand to enable replacement of any one or more of its component parts.

Claim 3
Dependent Claim
152 words
A modular mattress structure according to claim 1, in which said separable component parts include top and bottom screens defining insulators receivable on the top and bottom surfaces of said central core; and top and bottom pads of stuffing receivable on the top and bottom insulators respectively, said flange being secured to said top panel and tucking into said central core about its top marginal edge to hold the top insulator and top pad of stuffing in place, said bottom panel including an annular flange secured to the inside edge of the panel where the panel connects to the skirt, the flange extending beyond the end of the skirt and including within its free extending end an inextensible cord of perimeter less than the perimeter of the bottom panel, said flange tucking into said central core about its bottom marginal edge to hold the bottom insulator and pad of stuffing in place.
Claim 4
Dependent Claim
17 words
A modular mattress structure according to claim 1, in which said central core is comprised of polyfoam.
Claim 5
Dependent Claim
31 words
A modular mattress structure according to claim 3, including at least one pad of stuffing on the top surface of said polyfoam core surrounded and held in place by said flange.
Claim 6
Dependent Claim
14 words
