Reminiscent of the Fully Loaded Chair we saw back in February of last year (the chair made from more than 450 .12 guage shotgun shells)– The Tennis Ball Chair is constructed with a chromed steel frame, the original cushions were replaced with laser-cut quarter-inch thick oak veneer plywood. Twenty-five tennis balls were carefully fit inside the two layers and trapped in place. No word on comfort, but it sure is a nice conversation piece. As far as I can tell this puppy is a one of a kind and available through Etsy.
