Add the friction of an hour’s worth of gyrating movement on the chair’s seat and a little sweat and the next morning I was digging through a cupboard for an old jug of baby powder. Clothing wasn’t on the manufacturer’s list of 27 “safety points for attention,” but it did warn away those with “serious bleeding wounds,” people with “equipment trapped inside” and “persons that need a rest cure” from using it. Also, stay off it when you’re wet. Word to that.

Awesome article with the icing on the cake being the sweet video of this poor girl getting her ass kicked by the chair.
