Not happy with the chair. Makes a lot of creaking and klonking noises when I lean back in it. I am not a heavy guy and just don't feel secure sitting it in. Had high expectations based on reviews. Oh well.... ;-(
This chair is very comfortable and the adjustable (ish) lower back support is just where I need it. The only two complaints I would make are 1. It's not the easiest to assemble takes awhile etc. 2. The tilt lock does lock in place to keep you from being able to lean back if you don't want; however if you push back at all (i.e. pushing back from your desk etc.) it tilts just enough and is locked in that leaned back position so you have to reset it to be locked upright again...which is annoying. Over all its a good chair I'd probably make the purchase again because the price was right.
