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 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.
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 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.
