The Noden Adjust-A-Bench uses a pair of 26.25″ tall nesting frames that can ratchet up, using foot pedals, another 16.5″ via 12 locking stops (1.5″ increments) to provide the legs for a bench that can easily change height.
A basic kit (17″ W leg sets, 2 foot pedals, hardware package, and assembly instructions) costs $430 plus $60 shipping and handling. You provide the bench top (18″ min. recommended width) and the rails. Available accessories include different width castor packages (17″, 22″, 28″, and 40″; $160 plus $30 S & H), rail brackets, standard rails, and threaded rod. Complete benches (leg sets, bench rails, threaded rod, and solid hard maple butcher block top) are also available starting at $800 (60″ × 30″ × 1 3/4″ top, or 72″ × 24″ × 1 3/4″ top). The kit is designed and manufactured in the US.
I like the idea of an adjustable-height bench for many reasons, including that I would be less likely to tweak my back when the work surface is at a reasonable level. Have any Toolmongers used this bench? What’s your opinion?
