Hi, Stanford.

I bought this chair a month ago for 220$(including assembly fee.) I got a better chair from my friend, so I decided to sell this one.

This is Alera Elusion Series Mesh Mid-back Multifunctional chair and it is known to be "cheap" version of Herman Miller Aeron chair. It has very similar features of Aeron such as Mesh back or forward tilt. It also has back angle adjustments and height adjustments of course. It is selected to be best ergonomic chair under $300 by many of the sites and that's why I bought this one.(For example http://myergonomicchair.com/best-ergonomic-chairs-under-300/) If $900 is too expensive for you and you want to get a reasonable ergonomic chair, you definitely should go for this one.

Only for pickup please.
