Query: Hard as a rock- not for office use, and maybe not for a painter either

I bought this as a cheaper "starter" to try out the concept before buying a saddle chair. Verdict: Not for office use. The seat is as hard as a rock! Truthfully, I don't know how a painter could stand it either.I suppose you could rig up some sort of foam cushion for the seat or something, but otherwise, you're going to have one sore tushy. Also note, you're unlikely to be happy with it if you're less than 5'5" tall.I'll keep this short, but some of the other low-star reviews have valuable additional details and merit reading before purchase. Mine's at the Goodwill.
