Bought this chair as a replacement to an earlier generation of the chair (2010) - not sure of the name but also purchased at Staples. The main reasons for the selection was the multiple adjustments the lumbar support (new feature I am enjoying!) and the wheel base. Had to get a new chair because the left arm rest split and my clothes and left arm were being pinched in the split - OUCH! Would have given a 5 rating but am thinking I will have the same armrest challenges/issues with the new chair. Fingers crossed I do not!
I got the office chair as a Christmas Present and really like it it has the lumbar support I need. I had my own contraption attatched to my old office chair and this one replaced it. Much nicer!
Most chairs come with instructions which require advanced degrees to understand but this product was so easy to assemble that a 10 year old could do it. Everything was extremely well identified and the photos were accurate. Put this together in no time. The chair is also very comfortable and adjusts more ways than you will ever need. I would recommend this product to anyone.
