Mattress or mattress pad with gel section
View Patent ↗The invention generally relates to a mattress or a mattress pad with one or more gel sections. The gel section may provide improved support and comfort at a localized area of a mattress or a mattress pad.
1. A removable mattress topper pad, comprising
a foam padding layer having an inner perimeter and a top surface and having a recessed region formed in the top surface and defining a recess bottom wall, and
a gel insert layer comprising a porous foam body and gel intermixed with the foam body such that the gel occupies air pockets of the porous foam body, the gel insert layer having a top surface and an outer perimeter bordering the inner perimeter of the padding layer and adhered to at least one of the inner perimeter of the padding layer and the recess bottom wall to form the mattress topper pad, wherein the top surface of the padding layer and the top surface of the gel layer are substantially flush, wherein the mattress topper pad is configured to be removably attached to an underlying mattress, wherein the foam padding layer comprises a first zone having a convoluted foam surface, and a second zone defined by the gel insert layer having a smooth surface, and at least one additional zone having a convoluted and/or a smooth foam surface, and wherein top surfaces of the smooth surfaces and the convoluted surfaces are substantially flush relative to one another.
2. The mattress topper pad of claim 1 , wherein the foam padding layer comprises at least one of latex, visco-elastic foam, plastic, polymer, natural fiber, synthetic fiber.
3. The mattress topper pad of claim 1 , wherein the gel layer comprises at least one of a silicone gel, a PVC gel, a polyorganosiloxane gel, a NCO-prepolymer gel, a polyol gel, a polyurethane gel, a polyisocyanate gel, and a gel including a pyrogenically produced oxide.
4. The mattress topper pad of claim 1 , wherein the gel layer comprises a solid gel material.
5. The mattress topper pad of claim 1 , wherein the gel layer comprises a viscous gel material.
6. The mattress topper pad of claim 1 , wherein the gel layer comprises a visco-elastic gel material.
7. The mattress topper of claim 1 , wherein the gel layer comprises a foam gel.
8. The mattress topper of claim 1 , wherein the gel layer comprises a dimensionally stable gel.
9. The mattress topper pad of claim 1 , wherein the gel layer further comprises a bladder.
10. The mattress topper of claim 1 , wherein the recessed region is positioned at a location that is adjacent to at least one of a lumbar region, a center region and a head and neck region.
11. The mattress topper pad of claim 1 , wherein the gel layer is joined to the padding layer by a bond formed curing a gel curing process.
12. The mattress topper pad of claim 1 , further comprising a thin film sheet disposed over the gel layer.
13. The mattress topper pad of claim 1 , comprising a fabric layer covering the padding layer and the gel layer.
14. A method of manufacturing a mattress topper pad comprising
providing a foam padding material;
forming a recessed region in the padding material having a sidewall and a bottom wall;
providing a gel material into the recessed region and bonding the gel material to at least one of the side wall and the bottom wall, wherein the gel material is a gel infused foam layer
wherein the padding material comprises a first zone having a convoluted foam surface, and a second zone defined by the gel infused foam layer comprising a porous foam body and gel intermixed with the foam body such that the gel occupies air pockets of the porous foam body having a smooth surface, and at least one additional zone having a convoluted and/or a smooth foam surface, and wherein top surfaces of the smooth surfaces and the convoluted surfaces are substantially flush relative to one another.
15. The method of claim 14 , wherein providing the gel material into the recessed region in includes pouring a liquid gel material into the recessed region and curing the liquid gel.
16. The method of claim 14 , comprising covering the padding material and the gel layer with a fabric layer.
17. The method of claim 14 , comprising forming an outer perimeter of the gel layer into a shape.
18. The method of claim 14 , comprising connecting side rails to either end of the recessed region.
19. The method of claim 18 , comprising attaching a fabric layer to the side rails.
20. A mattress, comprising
a mattress core;
a foam padding layer positioned on top of the mattress core, having an inner perimeter and a top surface and having a recessed region formed in the top surface and defining a recess bottom wall, and
a gel insert layer having a top surface and an outer perimeter bordering the inner perimeter of the padding layer and adhered to at least one of the inner perimeter of the padding layer and the recess bottom wall, wherein the padding layer comprises a first zone having a convoluted foam surface; and a second zone defined by the gel insert layer comprising a porous foam body and gel intermixed with the foam body such that the gel occupies air pockets of the porous foam body, the gel insert layer having a smooth surface; and at least one additional zone having a convoluted and/or a smooth foam surface, and wherein top surfaces of the smooth surfaces and the convoluted surfaces are substantially flush relative to one another.
21. The mattress of claim 14 , wherein the gel layer comprises at least one of a silicone gel, a PVC gel, a polyorganosiloxane gel, a NCO-prepolymer gel, a polyol gel, a polyurethane gel, a polyisocyanate gel, and a gel including a pyrogenically produced oxide.
22. The mattress of claim 20 , wherein the gel layer comprises one of a solid gel material, a viscous gel material, a visco-elastic gel material, and a foam gel material.
23. The mattress of claim 20 , wherein the gel layer comprises a dimensionally stable gel.
24. The mattress of claim 20 , wherein the gel layer further comprises a bladder.
25. The mattress topper of claim 20 , wherein the recessed region is positioned at a location that is adjacent to at least one of a lumbar region, a center region and a head and neck region.
26. The mattress of claim 20 , wherein the gel layer is joined to the padding layer by a bond formed during a gel curing process.
27. The mattress of claim 20 , further comprising a thin film sheet disposed over the gel layer.
28. The mattress of claim 20 , comprising a fabric layer covering the padding layer and the gel layer.
