This is beautiful. It is a great design. I have had a similar design in my head but always wondered about the weight and the stabiliy.... so it had not gotten off my bucket list yet. Also yours is way better looking than the one in my head.
Swirt, the weight is heavy, but its a prototype made from Hickory. The Hickory was in my stack to burn in my shop wood heater and then I realized it had nice figure in some pieces, therefore, it became my material of choice for the prototype. The stability is no issue. The rear leg is of good width and gives the stool stability.
