Haworth ergonomic desk chair -- $150 obo

Hi! I bought this desk chair a couple of years ago, and now I am moving abroad and not taking it. It retails for $600 or so, but I'm selling it for $150! If that's too much, make me an offer. It's super comfortable and fully adjustable.

It is the same as the one that is in this website, but it is BLACK. I can take a photo if you are interested.
