I have a chair like this. It weighs 7 pounds, folds flat and the foot rest is permanently attached so you don't have to screw it on like with the wood ones.
http://www.bjs.com/tall-directors-chair---black.product.181978?dimId=I used to have a pay station made out of 4 old wood shutters that were 36 inches high, hinged together. (two across the front, one on each side. I then made a counter top out of an old piece of wood from the garage that was about 2 inches wider and deeper than the shutters when standing (which was about 14 inches deep x 26 inches wide (i think they were 12 inch shutters). It didnt cost me anything to make as I had gotten the shutters for $2 at a yard sale. I had little metal L brackets attached to the top so that I could just bolt in the top on each side shutter so it didnt move. I also painted the top piece of wood purple and decoupaged old photos to it and did some "donna dewberry" painting on it. People thought it was cool. I don't think I have any photos of it. I switched to something else a few years ago. Actually, just a 2 ft w x 18 inch deep folding table that I got at walmart for $13.00, that has 3 heights.
