This is a very oddly shaped chair. If you sit back in it the seat itself pushes against your thighs unless you have thin thighs or such a massive butt it sets your legs higher than the hump. The head rest is very uncomfortable it seems nearly impossible to get into a good position since it can only rotate. The maroon mesh looks great but is a bit rough if you generally sit with skin exposed to parts of the chair you're probably not gonna like it. The silver for the legs is kinda bad looking but it's sturdy. The wheels are the same wheels you get on most office chairs. Hopefully they won't clog up with long hair. The lumbar support is pretty nice? But again I can't comfortably sit back far enough to actually use it. I didn't even put the arms on (I never put them on computer chairs) so no comment on those. TL;DR: Made for a very specifically shaped person try it out before buying if you can. Still considering returning mine.
It's cool and comfortable but won't lock into incremental positions. The headrest adjusts without any tools or inconvenience. The seat is adjustable to a wide height range from low to high.
