Abstract

Claims (23)

1. A thermally activated mattress display comprising:

a mattress comprising a first portion comprising a temperature management feature; and

a removable fabric cover overlaying the mattress comprising a thermochromic material configured to change from a first color to a second color, the mattress having a top surface and the cover being substantially flush with the top surface.

2. The thermally activated display according to claim 1 , wherein the temperature management feature comprises a phase change material.

3. The thermally activated display according to claim 1 , wherein the temperature management feature comprises a ventilation feature or a heating feature.

4. The thermally activated display according to claim 1 , wherein the thermochromic material has an activation temperature in a range between about 26° C. and 29° C.

5. The thermally activated display according to claim 1 , wherein the first color or the second color is substantially colorless.

6. The thermally activated display according to claim 1 , wherein the thermochromic material comprises liquid crystals.

7. The thermally activated display according to claim 6 , wherein the liquid crystals are cholesteryl liquid crystals.

8. The thermally activated display according to claim 1 , wherein the cover is removable.

9. The thermally activated display according to claim 1 , wherein the mattress further comprises a second portion free of the temperature management feature abutting the first portion, wherein the cover overlays the first and second portions, and wherein the change from the first color to the second color is different for the first portion with the temperature management feature relative to the second portion without the temperature management feature.

10. The thermally activated display according to claim 9 , wherein when in use the first portion exhibits no color change and the second portion exhibits a color change.

11. A thermally activated mattress display comprising:

a mattress comprising a first portion comprising a foam having a temperature management feature; and

a removable fabric cover overlaying the mattress comprising a thermochromic material changing from a first color to a second color, the mattress having a top surface and the cover being substantially flush with the top surface.

12. The thermally activated display according to claim 11 , the mattress further comprises a second portion abutting the first portion, the second portion comprising a foam free of the temperature management feature, wherein the cover overlays the first and second portions.

13. The thermally activated display according to claim 11 , wherein the thermochromic material has an activation temperature in a range between about 26° C. and 29° C.

14. The thermally activated display according to claim 11 , wherein the first color or the second color is substantially colorless.

15. The thermally activated display according to claim 11 , wherein the thermochromic material comprises liquid crystals.

16. The thermally activated display according to claim 15 , wherein the liquid crystals are cholesteryl liquid crystals.

17. A mattress assembly comprising:

a mattress comprising a first portion having a temperature management feature and a second portion abutting the first portion not having the temperature management feature; and

a cover overlying the mattress comprising a thermochromic material changing from a first color to a second color in response to a change in temperature, the mattress having a top surface and the cover surface being substantially flush with the top surface, wherein the change from the first color to the second color is different for the first portion with the temperature management feature relative to the second portion without the temperature management feature.
