I ordered this based on what other reviews said, for me personally, I am short, my previous office chair is made for people taller than me so I never fit into the chair... I suffered back aches and needed a pillow behind my back and chair.  I got this thinking it would be more efficient.  The seat cushion however is a bit thin, (when you sit in it all day working from home, ) it needs more padding.  I bought this chair which I found on amazon approx 30.00 cheaper, and I still had to invest in a back cushion and seat cushion.  In all easy to install, came fast (hence three stars) but I wouldn't recommend.
