I spent an hour sitting in every leather chair at Staples. Choose one but after 2 days at home it was killing my back. Took it back and traded it for the Kroy mesh chair. The new chair is perfect...not as good looking leather but great for my back plus much less expensive than original leather chair.
I've only had the chair two weeks but I am totally pleased. Assembly instructions were a little sparse. It's comfortable with enough adjustments to customize it to the individual.
