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 reasonsā€”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]
