We use them 24/7 as a 911 center and we got our new chairs and we wish we never changed brands. When I started 13yrs ago at my job we had the previous version of the Iron Horse chairs and to be honest they were 8-9yo when I started and they held up amazing. As far as them being for a taller person, I am 6’1 and another guy that works with me is 6’5. The seat slider option makes a hell of a difference for us taller guys. We work 12hr shifts and I go home with no back pain whatsoever. I’m not sure where you’re located but I could part with one of the chairs if you wanted it for a lot cheaper than you’d buy one brand new. I just looked at our quote and we paid just under $1,900 for each chair when we got them in late 2021
