I am 6'5" and roughly 320 Lbs. This chair is made for people like me. The chair is incredibly comfortable but it is all held together with 6 Hex Bolts. The chair wobbles terribly and does not inspire confidence when you sit in it. I felt the same way at the store when I tested it but I told myself that it was probably just the staff having to put together a ton of chairs and maybe not doing the best job on this one. However that doesn't seem to be the case. This chair feels near identical to the chair in the store and I spent a good amount of time making sure the chair was put together well. At nearly 200 dollars out the door this chair is massively disappointing. On the bright side the chair sits high up and supports my weight on the pneumatic actuator so that's a plus.
When comparison shopping several stores for office chairs this one stood out far and above the best construction and comfort for the price point. Over 300 lbs and healing from 2 ruptured disks I'm highly confident this is the best purchase I could have ever made as far as ergonomic and size-friendly office furniture goes.
I am 6'4 and 325 lbs. Very comfortable firm and great height adjustments. I looked at a lot of big and tall chairs for the price and quality I couldn't be happier. Plus a Lifetime warranty!!!
