This chair is perfect for me! I am short so I needed it to be able to have a large range of heights. It also supports my lower back and has a great head rest. Highly recommend!
I don't think I would want to sit in this chair for really long periods of time - It may encourage me to take more breaks away from my desk throughout the day...which could be a good thing.
I love this chair! EXCEPT I have had 2 of them at work and the bar in the middle goes down to the floor and won't move back up! The chair seat is nice and roomy the mesh is comfy and I love the flexibility in the backrest. But once the middle bar hits the floor - you can't move it.
