Abstract

A mattress pad for supporting a human body includes an upper layer, a lower layer, and a wadding layer therebetween including three distinct zones arranged along the length of the pad for varying support of the human body; the first zone is configured to support a head portion and a neck portion; the second zone is configured to support an upper body portion and a lumbar portion; and the third zone is configured to support a lower back portion and leg portion wherein thickness and length in these zones varies for providing the varying support.

First claim

What is claimed is:

1. A mattress pad, comprising
(a) an upper layer defining a first exterior surface on a first side of the mattress pad, a lower layer defining a second exterior surface on a second side of the mattress pad opposite the first side, and a wadding layer comprising wadding located between the upper layer and the lower layer;
(b) wherein the upper layer, the lower layer, and the wadding layer are quilted together to form a quilt cake having a plurality of regions for supporting a human body on the first side of the mattress pad;
(c) wherein the plurality of regions comprises,
(i) a head region for supporting a head portion of a human body,
(ii) a neck region for supporting a neck portion of a human body,
(iii) an upper body region for supporting an upper body portion of a human body, and
(iv) a lumbar region for supporting a lumbar portion of a human body;

(d) wherein the head region has a thickness that is different from a thickness of the upper body region, the difference in thickness resulting at least in part from a variance in an amount of the wadding that is in each of the head region and the upper body region; and
(e) wherein each of the neck region and the lumbar region has no quilting pattern applied therein and each has a thickness that is greater than each of the thickness of the head region and the different thickness of the upper body region.

2. The mattress pad of claim 1 , wherein each of the plurality of regions extends the width of the first side of the mattress pad.

3. The mattress pad of claim 1 , further comprising a drop extending from the first side of the mattress pad for fitting the mattress pad on top of a mattress.

4. The mattress pad of claim 1 , wherein a quilting pattern is applied in the upper body region that demarcates the upper body region, and wherein a quilting pattern is applied in the head region that demarcates the head region.

5. The mattress pad of claim 1 , wherein the lumbar region has a greater lengthwise extent than a lengthwise extent of the neck region.

6. The mattress pad of claim 1 , wherein the head region has a greater lengthwise extent than a lengthwise extent of the neck region.

7. The mattress pad of claim 1 , wherein the upper body region has a greater lengthwise extent than a lengthwise extent of the lumbar region.

8. The mattress pad of claim 1 , wherein the upper body region has a greater lengthwise extent than a lengthwise extent of the head region.

9. The mattress pad of claim 1 , wherein the lumbar region has a greater lengthwise extent than a lengthwise extent of the neck region.

10. The method of claim 1 , wherein the thickness of the head region is different from the thickness of the upper body region at least in part from a variance in a density of the wadding in each of the head region and the upper body region.

11. The mattress pad of claim 1 , wherein the plurality of the regions of the mattress pad further comprises a lower back region for supporting a lower back portion of a human body, and a leg region for supporting a leg portion of a human body.

12. The mattress pad of claim 11 , wherein the leg region has a greater lengthwise extent than a lengthwise extent of the lower back region.

13. The mattress pad of claim 11 , wherein each of the plurality of regions extends the width of the first side of the mattress pad.

14. The mattress pad of claim 11 , wherein the head region, the neck region, the upper body region, the lumbar region, the lower back region, and the leg region collectively extend the length of the first side of the mattress pad.

15. The mattress pad of claim 11 , wherein the lower back region has a quilting pattern that is applied therein that demarcates the lower back region, and wherein the leg region has a quilting pattern that is applied therein that is different from the quilting pattern applied in the lower back region and that demarcates the leg region.

16. The mattress pad of claim 15 , wherein the upper body region has a quilting pattern that is applied therein that is the same as the quilting pattern that is applied in the lower back region.

17. A method of making a mattress pad having a plurality of regions for supporting the human body, comprising quilting together an upper layer, a lower layer, and a wadding layer to form a quilt cake with the upper layer defining a first surface on a first side of the mattress pad and the lower layer defining a second surface on a second side of the mattress pad opposite the first side, wherein a plurality of regions are defined in the mattress pad for varying support of different portions of a human body when laying on the mattress pad including a head region that is defined for supporting a head portion of a human body, a neck region that is defined for supporting a neck portion of a human body, an upper body region that is defined for supporting an upper body portion of a human body, a lumbar region that is defined for supporting a lumbar portion of a human body, a lower back region that is defined for supporting a lower back portion of a human body, and a leg region that is defined for supporting a leg portion of a human body, wherein the head region has a thickness that is different from a thickness of the upper body region, the difference in thickness resulting at least in part from the variance in an amount of wadding that is applied in each of the head region and the upper body region; wherein each of the neck region and the lumbar region has no quilting pattern applied therein and each has a thickness that is greater than each of the thickness of the head region and the different thickness of the upper body region; wherein the lower back region has a quilting pattern applied therein that is the same as the quilting pattern applied in the upper body region; and wherein the leg region has a quilting pattern applied therein that is different from the quilting pattern in the lower back region.

18. The method of claim 17 , wherein the thickness of the head region is different from the thickness of the upper body region at least in part from a variance in a density of the wadding in each of the head region and the upper body region.

19. A method of providing a mattress for improving quality of sleep of a person, comprising the steps of:
(a) providing a mattress pad comprising an upper layer defining a first exterior surface on a first side of the mattress pad, a lower layer defining a second exterior surface on a second side of the mattress pad opposite the first side, and a wadding layer comprising wadding located between the upper layer and the lower layer, wherein the upper layer, the lower layer, and the wadding layer are quilted together to form a quilt cake having a plurality of regions for supporting a human body on the first side of the mattress pad, including a first region, a second region, a third region, and a fourth region, wherein the first region has a thickness that is different from a thickness of the third region, the difference in thickness resulting at least in part from a variance in an amount of the wadding that is in each of the first region and the third region, and wherein each of the second region and the fourth region has no quilting applied therein and each has a thickness that is greater than each of the thickness of the first region and the different thickness of the third region; and
(b) attaching the mattress pad to the mattress such that the first region is located on the mattress for supporting a head portion of a human body when laying on the mattress pad, the s
