Best chair I've ever owned. It molds onto you like a glove by supporting your entire back especially with the adjustable lumbar support. This chair comes with all the adjustments you'll ever need. I have it set with the back straight up and locked in so that it won't rock back thus forcing me to seat straight and maintain my posture.
I requested this chair for my office job where I am at my computer for 6 - 8 hours a day. With a neck injury I find having the higher back and neck support to be beneficial. The chair has worked out great for me. 5 stars
