I am super pleased with this chair. Other desk chairs I end up with back pain after a short while. Not with this one! I have sat for long periods and do not experience any back pain. I love and definitely recommend this excellent chair.
Chair: Rated for 275 lbs. Me: Rated at 220 - 225 lbs. Pneumatic Cylinder: Nope. I've owned this for about 18 months (purchased in store not online so not exactly sure). I always check the weight rating on chairs. Okay so I did that. I even made sure there was a 20% margin of error. And yet this chair failed anyway leaving me with a sinking feeling that it needs to be replaced. Is it really too much to ask for a product to do what it promises? Apparently so.
