I am looking at the original guitar chair also. For a while I was considering a drum throne with a backrest, and decided I would be more happy with the original guitar chair. Allison Reynold's winter shop is just a 4 hour drive from me, so I will probably arrange a trip over there this fall (think fall foliage tour!) when Allison gets there from Alaska, to see whether I need the 17 inch or 19 inch version. I think I will want the 17 inch, even though I am average height at 5' 9". What I have found in my experimentation is that when I go with a slightly lower seat height, the angle on my left thigh on which I place a large dynarette cushion is ever so slightly above parallel with the floor, which aids in keeping the guitar snugly in place against my chest. Thanks for the report, and I'm looking forward to acquiring one of these chairs myself.
