At times we make more work out of a project than is needed. Perhaps one of the best simple solutions is to use a swivel office type chair, one without arms. You will find that you do not need locks on the wheels. It is handy to be able to just push over to grab a tool from another bench, and changing positions to see your work or just get comfortable is a breeze. Most of these chairs are height adjustable and by adding an extra cushion you have a seat that will not wear and tear on your backside.
