I wanted to build a stool for my son so he could easily reach the sink, counter, etc. without having to climb up onto the plastic stools we had around the house. My wife and I searched google for a design we liked and settled on the step stool plans over at Ana White. I used cherry and popular since that was what I had around the shop. I was considering using more traditional joinery so I could learn those skills but in the interest of time I went with screws. I used General Finishes Arm-R-Seal since I have had good results with their products in the past.
