At first, we were very happy with this chair. But now after just a few months of use, the back leans back too far--even when you have the pin pushed in to prevent it from moving. It's like trying to work in a recliner. To sit upright, you have to prop a pillow behind you, which negates the reason for buying it (the mesh back to allow air circulation. Very disappointed given the price. I would expect this of a $69 chair from Staples, but not a $200 chair.
A:
After only 4 months the chair is essentially useless
