I have been searching for a desk chair for almost a year. I have a roll top desk and was needing something with a lift because a normal chair just wasn't high enough to be comfortable not even adding a 2 inch padded seat to it. Most all the lift chairs came with caster wheels that didn't help because the width of the stand was 25 inches and I was working with a 22 inch clearing to pull my chair under my desk.  I just kept looking and found the same chair without casters and a clearing of 15.5, I ordered it and it's perfect.  A long search but the right chair came at the right time.  I'm happy.
