I have back pain and this chair provides the proper amount of support. The more expensive chairs were too cushy and leaned back too far. This chair keeps my back straight and my back pain has improved even when not using the chair.
I sat on quite a few chairs at staples and its was one of the best for comfort and durability it seemed like for the price. A lot of other chairs arms feel really week in the same price range when pressure is applied from the side. If you catch it on sale I would suggest getting it.
