It felt very comfortable in the store but after a 1.5 week trial it was no good for my back. I think it might have had something to do with the mesh design that had too much give with gravity.
I got this for my home "office" aka dining room table. I just love it and it's really comfortable. Good lumbar seat and neck/head support if you want to lean back. Travels easily across my carpet. I have back issues and it's so nice to be able to sit and not be in pain. I find the height adjustment good (I'm 5'9" with long legs) the unpadded arm rests are comfortable. Does it have all the bells and whistles as chairs 2x3 times more expensive - no! But what you get for your money is truly exceptional! I got the blue chair and it looks great with my table. It is a much deeper nicer blue than they show in the picture. You will not be disappointed.
Great chair easy to put together. Clear assembly instructions. High quality and getting it on sale made it an excellent value. Very happy with this purchase.
