ABSTRACT:
A mattress has a conventional spring core. Top and bottom insulators and padding are held in place by top and bottom cover assemblies. The cover assemblies are completely assembled before application to the core. Each cover assembly includes a horizontal panel with an annular vertical flange around its perimeter. Each flange has a hem in its free edge. Elongate rigid rods are held in the hems. Plastic wire ties on the flanges each enclose an upper rod, a lower rod and a peripheral portion of the core. When the ties are closed down to a reduced diameter, the rods and flanges are drawn together and anchored to the core. One of the cover assemblies has a loop member of a hook and loop fastener secured to the perimeter of the panel. The other cover assembly has an annular border skirt attached to the perimeter of the panel external to the flange with a binding tape covering the seam. The free edge of the border skirt also has a binding tape covering and a hook member of the hook and loop fastener adjacent the tape. The border skirt is pulled over the flanges until hook and loop fasteners can be joined together to seal the mattress. Binding tapes give the appearance of a conventional mattress with covers stitched closed on special mattress sewing machines, whereas the entire mattress can be assembled and disassembled for repairs by one worker with hand tools.
