so far I would recommend this chair.It was purchased to replace a smaller outdated chair.The main reason I liked it is the back of the chair extends very high for me and keeps my back tall and supportive.Also the arms are positioned well & are not the kind that loses the nuts and bolts underneath. The arms don't wiggle.
We bought this chair when my daughter's other office chair broke. It's a beautiful chair fairly easy to assemble and very comfortable. The price was also excellent. We are very happy with our new chair!
