I made a chair similar to the Catperch except that it hinges at the top instead of the rear leg hinging in the middle. The only thing I would do different is for my set up I have some large patio bricks that I use for the leveling pad of my DOB and the outriggers on the chair sometimes make it hard to position the chair close enough. So for me it would be better to have the outriggers on the back leg.
