Okay, I admit it. When I first saw this topic, I thought "Huh? 'Guitar stools'? My guitars have always been house-broken...".
But now that I have a better understanding of the subject, I'll say that I never much cared for stools myself so I'm afraid I'm no help to you. I'd like to have a PRS stool just because, but when I play I'm usually on my large chair/small loveseat. I can get really comfortable, have a nice drink handy if I want, and it's wide enough that the arms don't get in the way. Well-padded so dings and bumps aren't a worry. CD player and radio on one side of me, straps, tuners, small toolkit, etc. on the other, and the tv out front.
I did a little research, and there are lots of choices out there so good luck. Please let us know what you come up with.
