I received this two days after I ordered it, so it arrived quickly. However the packaging was a disaster. Basically the chair was in pieces, rattling around in a large box with no padding. There was a massive hole in the side of the box, and it was difficult to be sure whether anything was missing because the instructions appeared to apply to a different chair (one with arms). Still, it turned out that everything was there, and with a bit of logic and imagination it was fairly straightforward to put together - it only took me 10 minutes. The chair itself is very comfy. The seat adjusts up and down, and the backrest tilts and locks. The height of the backrest can also be adjusted up and down. There's lots of padding and first impressions are that it's quite comfy. I personally hate arms on an office chair, so I'm pleased with this. I think, though, that I might have been a bit lucky that the chair was undamaged despite the terrible packaging.
