Abstract

A customizable mattress topper system includes a first mattress topper of viscoelastic foam with a shaped top surface and a second foam mattress topper. The viscoelastic foam topper has a higher density than the second topper. The first mattress topper and second mattress topper are packaged and sold together as a system. The first mattress topper may be placed over the second mattress topper, or vice versa, and in various orientations over a bedding mattress as desired by a consumer to customize the level of cushioning support.

Claims (20)

1. A mattress topper system, comprising:

a first foam layer of viscoelastic foam having a top surface and a bottom surface, wherein said top surface is shaped with one or more projections; and

a second foam layer having a top surface and a bottom surface, wherein said second foam layer has a density less than said first foam layer,

wherein said first and second foam layers are provided together to a consumer as separately unadhered layers that may be variously oriented one atop the other by the consumer as the mattress topper system over a separate bedding mattress.

2. The mattress topper system of claim 1 , wherein the top surface of the second foam layer is shaped.

3. The mattress topper system of claim 2 , wherein the shaped top surface of the first foam layer has one or more projections, and wherein the shaped top surface of the second foam layer has one or more depressions, and wherein each projection is nestable within at least one of the depressions.

4. The mattress topper system of claim 1 , wherein the first foam layer has a foam density in the range of about 2 to about 6 pounds per cubic feet.

5. The mattress topper system of claim 1 , wherein the second foam layer has a foam density in the range of about 1 to about 2 pounds per cubic feet.

6. The mattress topper system of claim 1 , wherein the second foam layer is of viscoelastic elastic foam.

7. The mattress topper system of claim 1 , further comprising consumer instructions for varying the support level by placing the first foam layer and the second foam layer in different orientations over a mattress.

8. The mattress topper system of claim 1 , further comprising a package in which the first and second foam layers are packaged together for delivery to a consumer.

9. A method for varying cushioning support level of a mattress with a mattress topper system positioned atop the mattress, comprising:

providing a first foam layer of viscoelastic foam having a top surface and a bottom surface, wherein said top surface is shaped with one or more projections;

providing a second foam layer having a top surface and a bottom surface, wherein said second foam layer has a density less than said first foam layer and is separate and unadhered to said first foam layer so that it may be variously oriented above or below said first foam layer by a consumer; and

instructing the consumer to vary cushioning support level by positioning said first foam layer and second foam layer over a top surface of the mattress by specifying alternate foam layer configurations to increase cushioning support level.

10. The method of claim 9 , wherein the top surface of the second foam layer is shaped.

11. The method of claim 10 , wherein the shaped top surface of the first foam layer has one or more projections, and wherein the shaped top surface of the second foam layer has one or more depressions, and wherein each projection is nestable within at least one of the depressions.

12. The method of claim 9 , wherein the first foam layer has a foam density in the range of about 2 to about 6 pounds per cubic feet.

13. The method of claim 9 , wherein the second foam layer has a foam density in the range of about 1 to about 2 pounds per cubic feet.

14. The method of claim 9 , wherein the second foam layer is of viscoelastic foam.
