Seriously just do it. Buy this chair. I know you’re watching review videos of all your options and reading reviews but this thing will bring you more smiles and comfort than any other in it’s class.
I must say that I was very impressed at the ease of "Break-in" for the chair. One thing I especially like is the adjustable back adjustment. This chair can lock when leaning back: So many expensive chairs allow you lean back but then go back to the "up" position. Nice feature!
I love the different adjustments it has for your comfort. It has adjustments for lower back and forces you sit into a proper posture. I tried it out in the store first and love how it adjusts for a short person like myself being 5 ft and short legs.
This was a replacement. It took me a while to get to the right person but when I did they got the replacement to me right away. The chair is comfortable. But the cylinder doesn't last as long as the warranty. Several people in my office are having the same problem with their chairs as well.
I was having back spasms with a previous chair that has a seat made of foam over cardboard. This chair is very comfortable and I am not having the problems I had before.
