Remember those Thermochromatic t-shirts from the early '90s? Unsurprisingly, American Apparel started selling them last year. Now there's a sofa version from NunoErin, which is coated in a thermo-sensitive finish that changes color where your body touches it.
It's the "Love Handles" chair, and for obvious reasons—each oversized thigh will be imprinted on the chair for minutes later. If ever there was a chair that encouraged you to diet, it's this. [NunoErin via DesignBoom]
