We bought 2 grey/gray office chairs via eBay, from eBuyer.com. My wife was sitting on one of the chairs (she is quite petite) and as she rose from the chair, the arm of the chair broke into pieces and she tumbled to the floor hitting her head against the wall. I complained to the managing director of eBuyer.com and he laughed at me. They couldn't care less.

We tried to settle with them but in the end, we have filed a lawsuit against the company. It's the only thing they understand.
