This is a very comfortable chair. One of the main things I like is that is has a great many adjustment features so it can be customized to fit. I tried tnother chair from a different source and ended up returning it.
I've had this chair for about 6 months now and still love it. The different adjustments you make make it perfect for tailoring to an individual needs and the mesh back provides good air flow on those hot summer work days. I highly recommend it!
