We needed a couple of sturdy step stools for the bathrooms. My boys are not tall enough to reach the sink for hand washing and teeth brushing. Wally wanted $8 for a plastic thing. So I headed to the big orange store and bought a few 2X4's. $12 for both stools, plus the paint and screws which I already had.
I used the plans from the Skipper's Stool for some of my cuts. But I used 3-2X4 pieces for the top and shortened the legs to 10 inches. I was going to put on the side stretchers but it was super sturdy with the pocket holes and 2.5 inch pocket hole screws. So I left them off. A few coats of paint and they are good to go. Two of my boys can stand on one so that makes them a hit.
