Very impressed with this chair. It has great support for lower back and comfortable for all day...Also very easy to assemble instructions were very impressive..
The chair was easy to assemble though took a little work to figure out the levers once it was assembled. Otherwise it's been a good chair for the few weeks I have used it thus far.
This chair is very good for home office use. It is comfortable and seems sturdy. I note that the component parts are heavy and awkward for one person to assemble. I recommend asking a friend for help in assembling. Otherwise it is a great chair..
The seat is tilted slightly back putting pressure on the back of my legs and my legs went to sleep. I returned it. FYI the seat was all the way forward.
Chair is very comfortable and has really good lower back support. My only complaint is that it sits really high up. I believe the piston is longer than normal.
