CLAIMS
Claim 1 . A device comprising:
a chair mat including a first layer, a second layer, and a third layer, wherein the first layer includes a plastic, wherein the second layer includes an adhesive, wherein the third layer includes a cushioning foam, wherein the second layer is interposed between the first layer and the third layer, wherein the first layer is more rigid than the third layer.
Claim 2. The device of claim 1 , wherein the first layer is larger in area than the third layer.
Claim 3. The device of claim 2, wherein the first layer is beveled away from the third layer.
Claim 4. The device of claim 2, wherein the first layer is chamfered away from the third layer.
Claim 5. The device of claim 2, wherein the third layer is beveled towards the first layer.
Claim 6. The device of claim 2, wherein the third layer is chamfered towards the first layer.
Claim 7. The device of claim 2, wherein the first layer is studded past the third layer.
Claim 8. The device of claim 2, wherein the first layer includes a lip past the third layer.
Claim 9. The device of claim 2, wherein the first layer includes a projection past the third layer.
Claim 10. The device of claim 1 , wherein the chair mat includes a fourth layer, wherein the third layer is interposed between the second layer and the fourth layer, wherein the
fourth layer is configured to increase friction and thereby avoid skidding on at least one of a carpeted surface or a hard-floor surface.
Claim 1 1. The device of claim 1 , wherein the first layer includes a living hinge. Claim 12. The device of claim 1 , wherein the third layer includes a living hinge. Claim 13. The device of claim 1 , wherein the first layer includes a non-slip surface. Claim 14. The device of claim 1 , wherein the first layer includes a polyvinyl chloride. Claim 15. The device of claim 1 , wherein the first layer is irregular in texture. Claim 16. The device of claim 1 , wherein the first layer is opaque.
Claim 17. A method comprising:
accessing a first layer and a second layer, wherein the first layer includes a plastic, wherein the second layer includes a cushioning foam, wherein the first layer is more rigid than the second layer; and
securing the first layer to the second layer chemically such that a chair mat is formed.
Claim 18. The method of claim 17, wherein the securing includes interposing an adhesive between the first layer to the second layer.
Claim 19. A method comprising:
positioning a chair mat on a surface in proximity of a desk that is adjustable between a first height from the surface and a second height from the surface, wherein the chair mat includes a first layer, a second layer, and a third layer, wherein the first layer includes a plastic, wherein the second layer includes an adhesive, wherein the third layer includes a cushioning foam, wherein the second layer is interposed between the first layer and the third layer, wherein the first layer is more rigid than the third layer; sitting on a chair including a caster wheel such that the caster wheel rolls on the first layer as the desk is at the first height and the chair is in proximity of the desk; and standing on the first layer in proximity of the desk as the desk is at the second height.
Claim 20. The method of claim 19, wherein the first layer includes a portion that extends past the third layer, wherein the sitting includes directing the chair such that the caster wheel rolls on the portion, wherein the standing includes stepping onto the portion.
