I built this 25" modernist high stool for my workshop. The seat is black cherry, the bracing is red oak, the legs are white ash, the footrest is bubinga with wedged rosewood pegs. It is very stable yet very lightweight -- less than 7 lbs.
The hand-carved bicycle-style seat is very comfortable and low-stress.
After making this one I made some changes to the design for the future: Made the leg taper less extreme, switched to hickory for the bent braces, and switched from a very light varnish-style finish to oil.
You can see the updated model in my portfolio under 'Bentwood Stool'. The price range is driven by choice of wood. The low end of the range includes common domestic species like cherry, ash, oak, and hickory. Please contact us to discuss variations and customizations.
