I have had this chair for about 13 months now. It is simple to assemble and comfy for all-day sitting. Over time the plastic side assembly that holds the back and bottom together has not held up well to my constant leaning back and has bent. I'm about 260 lbs. and admittedly slouch a lot putting more pressure on the back than I should. I have the same chair for my assistant who is much smaller and she loves it. If you aren't as big as I and have better posture this is a wonderful chair for the money.
