Squeakiest. chair. ever. We have to spray it with lubricant like every other day or it's unbearable. Also not the best support on the back. Meh. Wish I had spent more money for a better chair.

Update: Six months later, it is completely broken. No longer rocks, sounds like something has bent. I'm a normally sized person. This chair is not going to stand up to any test of time. Horrific waste of money.
