Abstract

Mattresses and improved fabric covers for providing mattresses that have smooth surfaces. Additionally, methods for manufacturing non-quilted mattress covers and for manufacturing mattresses employing non-quilted mattress covers. The systems and methods described herein include mattress panels that can be manufactured separate from the inner core construction, and laid over the inner core to be fastened in place as a sleeping surface for the mattress. Optionally, these mattress panels can include a layer of fire retardant material, that may be added as a layer of material or that may be incorporated into one or more of the layers, such as a filler layer, in the mattress panel.

First claim

What is claimed is:

1. A mattress, comprising,
a mattress core,
a non-quilted crowned panel lying on the mattress core, wherein edges of the panel have a height of about 0.25 inches to about 1.0 inch and the center portion of the panel has a height of about 1 inch to about 4 inches, the non-quilted crowned panel consisting of,
a fabric layer including a top surface and a bottom surface;
a fire-resistant layer provided on a bottom surface of the fabric layer;
a filler layer having a uniform thickness from 0.5 inches to 5 inches, wherein the filler layer comprises a viscoelastic foam having an indention load deflection of about 10 to 40 and a density of about 1.0 to 5.0 pounds per cubic foot, wherein the filler layer is disposed below the fire-resistant layer; and
a backing layer underlying the filler layer;

wherein the fabric layer, fire-resistant layer, filler layer, and backing layer are compressively joined at respective edges such that the non-quilted crowned panel expands in height from the edge towards a center section of the panel, wherein the center section of the panel is free of stitching, wherein the filler layer in the center portion is not restrained by the fabric layer, and wherein the non-quilted mattress crown panel has a separate flange extending from the non-quilted crowned panel attached to side surfaces of the mattress core to secure the non-quilted mattress crown panel to the mattress core.

2. The mattress of claim 1 , wherein the edges are covered with a strip of a fabric material.

3. The mattress of claim 1 , wherein the filler layer includes a gel section to form a support zone.

4. The mattress of claim 3 , wherein the support zone corresponds to a lumbar region.

5. The mattress of claim 1 , wherein the fire-resistant layer includes a material selected from the group consisting of a halogenated material, Kevlar®, a thermoplastic material, inorganic fire-retardant materials, organophosphorous materials, fire resistant balanced corespun yarn, a layer of fire retardant treated cotton, a layer of fire retardant treated polyurethane, and fire retardant treated paper.

6. A mattress, comprising,
a mattress core,
a non-quilted crowned panel lying on the mattress core, wherein edges of the panel have a height of about 0.25 inches to about 1.0 inch and the center portion of the panel has a height of about 1 inch to about 4 inches, the non-quilted crowned panel consisting of,
a fabric layer including a top surface and a bottom surface;
a filler layer having a uniform thickness from 0.5 inches to 5 inches, wherein the filler layer comprises a viscoelastic foam having an indention load deflection of about 10 to 40 and a density of about 1.0 to 5.0 pounds per cubic foot, wherein the filler layer is disposed below the fabric layer; and
a backing layer underlying the filler layer;

wherein the fabric layer, filler layer, and backing layer are compressively joined at respective edges such that the non-quilted crowned panel expands in height from the edge towards a center section of the panel, wherein the center section of the panel is free of stitching, wherein the filler layer in the center portion is not restrained by the fabric layer, and wherein the non-quilted mattress crown panel has a separate flange extending from the non-quilted crowned panel attached to side surfaces of the mattress core to secure the non-quilted mattress crown panel to the mattress core.

7. The mattress of claim 6 , wherein the edges are covered with a strip of a fabric material.

8. The mattress of claim 6 , wherein the filler layer includes a gel section to form a support zone.

9. The mattress of claim 8 , wherein the support zone corresponds to a lumbar region.

10. A mattress, comprising,
a mattress core,
a non-quilted crowned panel lying on the mattress core, wherein edges of the panel have a height of about 0.25 inches to about 1.0 inch and the center portion of the panel has a height of about 1 inch to about 4 inches, the non-quilted crowned panel consisting of,
a fabric layer including a top surface and a bottom surface;
a filler layer having a uniform thickness from 0.5 inches to 4 inches, wherein the filler layer comprises a viscoelastic foam, wherein the filler layer is disposed below the fabric layer, and wherein the filler layer in the center portion is not restrained by the fabric layer; and
a backing layer underlying the filler layer;

wherein the fabric layer, filler layer, and backing layer are compressively joined at respective edges such that the non-quilted crowned panel expands in height from the edge towards a center section of the panel, wherein the center section of the panel is free of stitching, and wherein the non-quilted mattress crown panel has a separate flange extending from the non-quilted crowned panel attached to side surfaces of the mattress core to secure the non-quilted mattress crown panel to the mattress core.
