Abstract

A quilted zoned topper formed with a quilted panel and a memory foam is disclosed. The quilted panel has a ticking material, a backing material, and a support material having a degree of compression provided between the ticking and backing materials. The ticking material, the support material and the backing material all are quilted together by a stitching pattern providing an increased amount of stitching in a center section of the quilted panel than adjacent head and foot sections of the quilted panel such that the support material pre-compresses in the center section thereby defining a pocket. The memory foam is provided in the pocket. A mattress provided with the quilted zoned topper is also disclosed.

Claims (26)

1. A quilted zoned topper comprising:

a quilted panel having a ticking material, a backing material, and a support material having a degree of compression provided between the ticking and backing materials, the ticking material, the support material and the backing material all being quilted together by a stitching pattern providing an increased amount of stitching in a center section of the quilted panel than adjacent head and foot sections of the quilted panel such that the support material pre-compresses in the center section thereby defining a pocket; and

a memory foam provided in the pocket.

2. The quilted zoned topper of claim 1 , wherein the ticking material comprises an upholstery ticking.

3. The quilted zoned topper of claim 1 , wherein the backing material comprises a non-woven fabric.

4. The quilted zoned topper of claim 1 , wherein the support material comprises a polymer foam or fill layer.

5. The quilted zoned topper of claim 1 , wherein the center section ranges in size from about ¼ to about ½ of the total area of the quilted zoned topper.

6. The quilted zoned topper of claim 1 , wherein the stitching pattern is selected from a star pattern, a circle pattern, a swoop pattern, a ribbon pattern, a 213 pattern, and a 301 pattern.

7. The quilted zoned topper of claim 1 , wherein the memory foam is a polyurethane foam with a bulk density ranging from about 1.8 to about 4.0 pounds per cubic foot.

8. The quilted zoned topper of claim 1 , wherein the memory foam has a thickness ranging from ½ inch to 1 inch.

9. The quilted zoned topper of claim 1 , further comprising an elasticized skirt of material which is attached to the periphery of the topper.

10. A mattress comprising the quilted zoned topper of claim 1 .

11. A mattress comprising:

an innerspring assembly having a plurality of spring elements and defining a support surface;

at least one convoluted foam layer positioned over the support surface of the innerspring assembly and having a first density, and

a memory foam layer positioned over the convoluted foam layer opposite to the support surface, the memory foam layer having a density greater than the convoluted foam layer, and

a quilted panel having a ticking material, a backing material, and a support material having a degree of compression provided between the ticking and backing materials, the ticking material, the support material and the backing material all being quilted together by a stitching pattern providing an increased amount of stitching in a center section of the quilted panel than adjacent head and foot sections of the quilted panel such that the support material pre-compresses in the center section thereby defining a pocket, wherein the quilted panel is provided over the convoluted and memory foam layers such that the memory foam layer is provided in the pocket.

12. The mattress of claim 11 , wherein the convoluted foam layer has a bulk density of about 1 pound per cubic foot.

13. The mattress of claim 11 , wherein the ticking material comprises an upholstery ticking.

14. The mattress of claim 11 , wherein the backing material comprises a non-woven fabric.

15. The mattress of claim 11 , wherein the support material comprises a polymer foam or fill layer.

16. The mattress of claim 11 , wherein the center section ranges in size from about ¼ to about ½ of the total area of the mattress.

17. The mattress of claim 11 , wherein the stitching pattern is selected from a star pattern, a circle pattern, a swoop pattern, a ribbon pattern, a 213 pattern, and a 301 pattern.

18. The mattress of claim 11 , wherein the memory foam layer is a polyurethane foam with a bulk density ranging from about 2.6 to about 4.0 pounds per cubic foot.

19. The mattress of claim 11 , wherein the memory foam layer has a thickness ranging from ½ inch to 1 inch.

20. The mattress of claim 11 , wherein the convoluted foam layer has an egg-carton pattern.
