I was a little nervous about the significant outlay for this one, but - after using the chair for a couple of months now - I have absolutely zero regrets. It's very comfortable, and I use it whenever I can.
Adjustable width makes it much more comfy than the Bambach (which I have used for a couple years prior to buying my Salli). The wheels seem to be of high quality and allow me to wheel around the clinic very easily.
So far so good - it is a big adjustment as it changed the height that my computer needed. This changed the way my arms hang when I type. I am not fluent yet - some slight improvement for the comfort of my back - as now I stand more then I used to before.
I was glad I went to the storage location to be briefed so I could see what I was actually buying.
Now I can zoom around on my wood floor with my roller blade wheels. So glad I bought them
