Abstract

Mattress assemblies and/or pillows include at least one auxetic foam layer.

Claims (16)

1 . A mattress assembly, comprising:

at least one auxetic foam layer having a negative Poisson's ratio.

2 . The mattress assembly of claim 1 , wherein the at least one auxetic foam layer is provided within a top panel layer, a quilt panel layer, an upholstery layer, an innercore, and combinations thereof.

3 . The mattress assembly of claim 1 , wherein the at least one auxetic foam layer is proximate to a sleeping surface of the mattress assembly spanning at least a portion of the length and/or width of the sleeping surface.

4 . The mattress assembly of claim 1 , wherein the at least one auxetic foam layer further comprises a phase change material.

5 . The mattress assembly of claim 1 , wherein the negative Poisson's ratio is in a range from −0.5 to −1.

6 . The mattress assembly of claim 1 , wherein the mattress assembly comprises multiple foam layers stackedly arranged on top of one another, wherein at least one of the multiple foam layers comprises the auxetic foam layer.

7 . The mattress assembly of claim 1 , wherein the at least one auxetic foam layer has an indention load deflection (ILD) at 25% deflection of 5-120 pounds force and for 65% deflection of 6.8-188 measured in accordance with ASTM D-3574 and/or ASTM D 3575.

8 . The mattress assembly of claim 1 , wherein the at least one auxetic foam layer has a density from about 0.5 to about 8 pounds per cubic foot.

9 . The mattress assembly of claim 1 further comprising one or more non-auxetic foam layers having a positive Poisson's ratio.

10 . A pillow comprising:

at least one auxetic foam layer having a negative Poisson's ratio; and

an envelope encapsulating the at least one auxetic foam layer.

11 . The pillow of claim 10 further comprising layers of non-auxetic foam, feathers, fiber padding or combinations thereof within the envelope.

12 . The pillow of claim 10 , wherein the at least one auxetic foam layer further comprises a phase change material.

13 . The pillow of claim 10 , wherein the negative Poisson's ratio is in a range from −0.5 to −1.
