US Patent:

6782575, Aug 31, 2004

Filed:

Sep 5, 2003

Appl. No.:

10/655016

Inventors:

Rick D. Robinson - Tampa FL

Assignee:

Steven J. Antinori - Tampa FL

International Classification:

A47C 2716

US Classification:

5740, 5736, 5739, 5727

Abstract:

A mattress core is defined by a base core to which is bonded upper and lower corrugated outer layers each having oppositely directed corrugations, and side rails bonded to at least sides of the base core. The side rails have a height corresponding to the distance between valleys of opposite corrugated outer layers. The mattress core and mattress have an ILD range of substantially 26 ILD to 50 ILD for the side rails, 24 to 40 ILD for the base core and 12 to 45 ILD for each of the corrugated outer layers. The base core and the outer layers also collectively define a torso firmness zone and opposite head and foot firmness zones with the torso firmness zone being substantially between 20% to 30% more dense than the head and foot firmness zones. Ends of the mattress core and mattress are devoid of end rails.

International Classification:

A47C 2715

US Classification:

5727

Abstract:

A method of manufacturing mattresses is achieved by providing first and second layers of latex material having different indentation load deflection values. Each layer is then cut lengthwise along a longitudinal plane, preferably a medial plane to define first and second layer portions of the first and second layers each of an identical height. The layer portions are then cross united and adhesively bonded together thereby producing a mattress possessing a composite load deflection value dictated by the different indentation load deflection values of the starting layers. Preferably matching recesses are formed in the first and second layer portions of both layers. Medial recesses receive postural inserts of relatively high ILD values, whereas transverse recesses at headed foot sections are aligned to define voids at the foot and head sections of the mattress to provide head and foot relief.
