I am 6'2" and the back of this chair is too short for me. When trying to sit upright in the chair the neck rest pushes against the back of my shoulders. It is okay when I'm leaning back but then I have to curl to have my back supported. I don't see a way to lift the back of the chair to match my frame.
I am so happy with the support I get from this chair. Due to the pandemic I will be working from home from now on. This chair has been so helpful for back support.
