Going on six months of me having this chair and it gets a failing grade. The seat is no longer stable. It tilts, rocks and leans, and loudly squeaks and crackles with each gesture I make. The seat no longer maintains its highest height. It sinks down under my weight. I’m 250 lbs and before buying it, I specifically wanted to know the weight capacity. When the description said it can accommodate 330 lbs I felt confident I was getting a quality chair. I wouldn’t recommend this chair for anyone over 200lbs. In fact… let’s make it 180.  I bought the protection plan and am about to file a claim.
