Easy install. The back-support is bad.  Seat doesn't really attached to the base, but simply sits on it.  It's secure in that regard, but if, someone were to lift the hair by the seat, it might fall apart. Since the backrest gets uncomfortable fairly quickly, probably won't be best for prolonged computer use. I'm going to use this in my workshop instead as solely a task chair where I wouldn't have to sit for a long period of time.
