We are using this as a computer chair, and my Husband and I are a foot apart in height, so it's nice to have the adjustable feature.  The 7 year old in me had to twirl and go up and down when it arrived (just to make sure, of course, that it is solid) , and it seemed to hold up well.  You won't fall asleep in it or anything, but it is good and functional, especially if you have a tricky bar height, or multiple heights using it.   Looks kinda cool too, very shiny!
