Very comfortable and sturdy chair. Seems to be well-built doesn't feel cheap at all. The adjustment that allows you to tilt back is fixed so that the seat back and seat itself are at a fixed angle...you can tilt the whole thing back (think of a kid tilting chair on back two legs). I wish the back had the ability to recline independently of the seat itself but that's not a big deal for me. Overall great chair.
Overall-- good quality chair! Hard to beat such an amazing value for the price (on sale). It beats sitting on a step stool (which I was doing for a few days prior to receiving the chair) for sure. Only qualms: no significant lumbar support the arm rests do not adjust and relatively flimsy front lip so I have a slight tendency to slide forward while sitting which requires occasional re-positioning in the chair. Otherwise I'd highly recommend this chair for everyday use.
