Great chair for the price. The fabric on the seat is slightly uncomfortable when I wear shorts. I like all of the adjustments and the lumbar support has been great.
I like most of the things that adjust on this chair...up down forward tilt adjustable tension. The only thing that is annoying is that the back seems loose. There is an adjustment knob on the back but it doesn't do anything to tighten the back or secure it to a certain height. I don't know if you just have to pay more to get that option or it is defective. I got it on a sale though and the price on sale was good.
Chair went together easily and is a great fit for my writing desk. Multiple adjustments for seat angle back pressure and rocking make it quite versatile and comfortable to sit in for long periods.
