I paid $59 but it's on sale for $49 with free shipping. Very comfortable. The seat part has two poles that slide on easily. We are shorter than average and I'm going to cut a couple of inches off these poles to let my feet easily sit on the ground. For average or taller folks it will work fine out of the box. I don't know if they have them in the stores but shipping was very quick.
