I've got an adjustable height office type chair as well. It think it was called a "supervisor's chair" because it is taller than normal. It swivels and has castors which are both handy. I have back issues and I don't think I could take a plain stool for long. When I first started scrolling I was standing but that didn't last long, even with an anti-fatigue mat. It wasn't cheap (though I was fortunate enough to get it for Christmas) but it would have been well worth the investment if I'd had to buy it myself.
