My son & I were exploring a music store recently & I casually sat down on a drum throne. Oh my goodness it was sooooooo comfortable. Very similar to a saddle chair, (if not the exact same!) and it just felt so 'right' to me.
It had a 'lip' in the back instead of a full back, and needed wheels - but IMO, would have made a fantastic sewing chair. So if you are seeking a new saddle type chair - don't be afraid to look .outside the box' ~ in a music store. =)
