Abstract
A mattress pad for supporting a human body includes an upper layer, a lower layer, and a wadding layer therebetween. The wadding layer includes 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. Thickness and length in these zones varies for providing the varying support.
Claims20
A mattress pad, comprising
- (a) an upper layer defining an exterior surface on a top side of the mattress pad, a lower layer defining an exterior surface on a side of the mattress pad opposite the top 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 and define a plurality of support zones for supporting a human body on the top of the mattress pad;
- and
- (c) wherein the plurality of support zones comprises,
- (i) a first support zone comprising,
- (A) a quilted head region for supporting a head portion of a human body, and
- (B) a non-quilted neck region for supporting a neck portion of a human body,
- (C) wherein the quilted head region has a thickness that is different from the thickness of the non-quilted neck region, the difference in thickness resulting from at least one of a variance in an amount of the wadding used in each of the quilted head region and the non-quilted neck region and a variance in quilting applied in each of the quilted head region and the non-quilted neck region;
- and
- (ii) a second support zone comprising,
- (A) a quilted upper body region for supporting an upper body portion of a human body, and
- (B) a non-quilted lumbar region for supporting a lumbar portion of a human body,
- (C) wherein the quilted upper body region has a thickness that is different from the thickness of the non-quilted lumbar region, the difference in thickness resulting from at least one of a variance in an amount of the wadding used in each of the quilted upper body region and the non-quilted lumbar region, and a variance in quilting applied in each of the quilted upper body region and the non-quilted lumbar region.

A method of making a mattress pad having a plurality of support zones for supporting the human body, comprising the steps of:
- (a) quilting together an upper layer, a lower layer, and a wadding layer comprising wadding located between the upper layer and the lower layer such that the upper layer defines an exterior surface on a top side of the mattress pad and the lower layer defines an exterior surface on a side of the mattress pad opposite the top side, and such that a plurality of support zones are defined in the mattress pad for varying support of different portions of a human body on the top of the mattress pad;
- (b) wherein step (a) comprises varying the filling and quilting of the mattress pad in defining the plurality of support zones such that,
- (i) a first support zone is defined comprising,
- (A) a quilted head region for supporting a head portion of a human body, and
- (B) a non-quilted neck region for supporting a neck portion of a human body,
- (C) wherein the quilted head region has a thickness that is different from the thickness of the non-quilted neck region, the difference in thickness resulting from at least one of a variance in an amount of the wadding used in each of the quilted head region and the non-quilted neck region and a variance in quilting applied in each of the quilted head region and the non-quilted neck region;
- and
- (ii) a second support zone is defined comprising,
- (A) a quilted upper body region for supporting an upper body portion of a human body, and
- (B) a non-quilted lumbar region for supporting a lumbar portion of a human body,
- (C) wherein the quilted upper body region has a thickness that is different from the thickness of the non-quilted lumbar region, the difference in thickness resulting from at least one of a variance in an amount of the wadding used in each of the quilted upper body region and the non-quilted lumbar region, and a variance in quilting applied in each of the quilted upper body region and the non-quilted lumbar region.
