Sturdy, SO easy to put together, and rolls with ease on my rug! I have a tiny room in Brooklyn with a loft bed above my desk, so I sit for long hours in this chair... My only concern before getting it home was whether the placement of the “arm rests” was going to be comfortable... (the look of the chair didn’t exactly have a clear arm rest, that I could discern....) but never fear! It’s extremely comfortable PLUS the seat is much wider and deeper than I expected! 10 out of 10!
