Mattresses including spacer fabric and related methods
A mattress assembly includes a base core layer and an inner core located over the base core layer. The inner core includes coil springs. The mattress assembly also includes a side panel assembly located around a perimeter of the inner core. The side panel assembly includes a spacer fabric located over and transverse to the base core layer. The spacer fabric includes a first knit layer, a second knit layer, and an inner fibrous material located therebetween. Methods of forming the mattress assembly are disclosed.
1. A mattress assembly, comprising
a base core layer;
an inner core located over the base core layer, the inner core comprising coil springs; and
a side panel assembly located around at least a portion of a perimeter of the inner core, the side panel assembly comprising a spacer fabric located over and extending transverse to the base core layer, wherein the spacer fabric comprises a first knit layer, a second knit layer, and an inner fibrous material located therebetween, the first knit layer and the second knit layer having a greater elasticity along a vertical axis of the side panel assembly relative to an elasticity along a lateral axis of the side panel assembly, transverse to the vertical axis.
2. The mattress assembly of claim 1 , further comprising:
at least one elastomeric cushion member located over the inner core; and
a stabilizing material located on a lower surface of the at least one elastomeric cushion member.
3. The mattress assembly of claim 2 , wherein the stabilizing material comprises a thin material comprising cotton spandex adhered to the lower surface of the at least one elastomeric cushion member.
4. The mattress assembly of claim 2 , further comprising:
an upper foam layer located between the inner core and the at least one elastomeric cushion member;
a cover located over the upper foam layer, the cover disposed around at least a portion of the side panel assembly; and
a top layer located between an upper surface of an uppermost elastomeric cushion member and the cover.
5. The mattress assembly of claim 4 , wherein a lower surface of the spacer fabric abuts an upper surface of the base core layer and an upper surface of the spacer fabric abuts a lower surface of the upper foam layer.
6. The mattress assembly of claim 5 , wherein a region located between the upper surface of the base core layer and the lower surface of the upper foam layer is substantially free of foam material.
7. The mattress assembly of claim 4 , wherein an outer surface of each of the base core layer, the spacer fabric, the upper foam layer, and the at least one elastomeric cushion member defines an outer surface of the mattress assembly.
8. The mattress assembly of claim 4 , further comprising fasteners coupled between the spacer fabric and at least one of the base core layer, the coil springs, or the upper foam layer, wherein the fasteners comprise at least one of hog rings, zippers, stitching, sewing, pockets, staples, buttons, heat fusing, or adhesives.
9. The mattress assembly of claim 4 , wherein the spacer fabric is sewn into a side paneling of the cover.
10. A mattress assembly, comprising: a base core layer;
an inner core located over the base core layer, the inner core comprising at least one coil spring; and
a side panel assembly located around at least a portion of a lateral perimeter of the inner core, the side panel assembly comprising a spacer fabric including:
a first knit layer comprising at least one of a knit, a cloth, or a polymeric film and having a greater elasticity along a vertical axis of the side panel assembly relative to an elasticity along a lateral axis of the side panel assembly, transverse to the vertical axis;
a second knit layer comprising at least one of a knit, a cloth, or a polymeric film and having a greater elasticity along a vertical axis of the side panel assembly relative to an elasticity along a lateral axis of the side panel assembly, transverse to the vertical axis; and
an inner fibrous material comprising extruded woven fibers between the first knit layer and the second knit layer.
11. The mattress assembly of claim 10 , further comprising at least one elastomeric cushion member located over the inner core.
12. The mattress assembly of claim 11 , wherein the spacer fabric extends from a location proximate a lower surface of the base core layer to a location proximate an upper surface of an uppermost elastomeric cushion member such that an outer surface of the spacer fabric defines an entire outer lateral surface of the side panel assembly.
13. The mattress assembly of claim 11 , wherein the at least one elastomeric cushion member comprises interconnected buckling walls.
14. A method of forming a mattress assembly, comprising:
providing a base core layer as a substrate for a mattress;
disposing a plurality of coil springs positioned within individual casings in an inner core located over the base core layer;
disposing an upper foam layer over the inner core;
disposing at least one elastomeric cushion member over the upper foam layer;
disposing a spacer fabric around at least a portion of a perimeter of the inner core, including abutting a lower surface of the spacer fabric against an upper surface of the base core layer and abutting an upper surface of the spacer fabric against a lower surface of the upper foam layer, a thickness of the spacer fabric being substantially equal to a distance that each of the base core layer, the spacer fabric, the upper foam layer, and the at least one elastomeric cushion member extend beyond the inner core, the spacer fabric defining at least a portion of a side panel assembly of the mattress, the spacer fabric comprising a first knit layer, a second knit layer, and an inner fibrous material located therebetween, the first knit layer and the second knit layer exhibiting a first compressibility along a vertical axis of the mattress having a relatively greater compressibility than that of a second compressibility along a first horizontal axis of the mattress, transverse to the vertical axis, and a third compressibility along a second horizontal axis of the mattress, transverse to the vertical axis and the first horizontal axis.
15. The method of claim 14 , further comprising:
adhering a thin stabilizing material to a lower surface of the at least one elastomeric cushion member; and
adhering a lower surface of the thin stabilizing material to an upper surface of the upper foam layer.
