I was skeptical in getting this chair. But after putting it together it fit right under my table. The ergonomics on the chair are fantastic. It feels like the material is good and i am very satisfied with this chair.
Unlike the advertisements the arms don't move forward/backward nor in/out. I'm not going to unscrew the six bolts to move it 1/2 inch. The arms do move up and down.
This is a nice and comfortable ergonomic office chair. I have issues with lower back pain even with moderate amount of sitting. This chair has helped a lot with providing support at all the right places. I would have given 5 stars if the lumber support had more adjustment room.
The staff at the store were very helpful. I was disappointed that there was not a sample set up to try first. Also the box did not have a lot of detail on it. I wanted to be sure that is was adjustable so that I could sit ergonomically. The associate looked it up on his cel phone and assured me it was. Putting it together was quite a feat. the parts were quite heavy and difficult to maneuver. Now that its up and rolling around I love it.
I now have one of these in the office and one at home. Two of my co-workers have purchased this chair after trying mine. It is cool and supportive and has enough features to be extremely comfortable for lots of different people. This is a great chair.
