The chair provides good lower back support. I can sit in it for many hours. I also like the the adjustable arm rests which make it easier to type on my laptop.
I have bought many office chairs in my life time and this is by far the BEST chair that I've ever had the pleasure to sit in all day long. It's so comfortable and flexible.
I was hesitant reading the reviews saying it's not good for tall people but it's perfect for me and I'm 6-6"1. The headrest can be extended a bit so might suit even taller people. The mesh material is airy and flexible great choice so far.
