I would recommend this chair, but make sure you follow the instructions well and have a lot of patience. I struggled with attaching the base (legs) to the seat. Luckily the legs are all one piece pre-assembled (when you open the box; it's just the seat and the legs on a metal base) so you just have to match up the holes well. That is where I struggled as the bolts didn't want to go into the threads well. I finally got it working though.
 
I took off one star because my grey shell seat arrived with a slight ding in it. Otherwise, very comfy chair and inexpensive Mid Century reproduction that looks and feels high quality.

Pros: Great looking chair; good quality materials.
Cons: A bit of a challenge to put together.
