I liked this chair very much when I first bought it I found it easy to assemble and comfortable as many other reviewers did. However barely 6 months after I purchased it the chair is now broken in such a way as to be completely unusable. The base of the seat below the mesh has one giant crack clear across it as well as large cracks in other key places. It's an office chair it doesn't see a lot of "action" as it were and I certainly don't think I've given it the kind of beating that would result in this kind of damage. I have to say I am very disappointed.
The chair was very easy to put together. It has a great lumbar support whichI have not had in previous chairs. It sits very comfortably. I am very pleased that I purchased it. As with other chairs I have purchased I do not attach the arm rests they just get in the way.
My home office chair was about 16 years old and needed replacing. I purchased this chair on sale online at Staples.com and picked it up an hour later. Assembly took 20-30 minutes and was very easy all tools included. The chair is very tall in it's highest position which I love. After a week I purchased another one for work.
