Love the chair. Very comfortable good support and seems well-made. Several store employees really pushed us to buy an extended three-year warranty which was making my husband and me worry about its long-term durability. My desk chair at the office has lasted over 15 years. If this one doesn't make it past three years I will never buy a chair or other products from Staples again. We do not believe you should have to purchase extended warranties for furniture.
I am petite and find this chair to be very adequate for my size. It is low enough that my feet touch the floor and my back touches the back of the chair. It has many adjustments for taller people as well. It has a springy quality and can tip which feels responsive. It rolls nicely and feels very quality. I have been using it regularly for two weeks.
We purchased this chair for our home office from which I'm currently working full time. I wanted something that was very comfortable offered excellent back support and had a breathable fabric. This chair fit all of the criteria really well. It was also extremely easy to assemble. In fact the assembly parts were better organized than for any piece of furniture I've ever put together in my life. My job requires that I be at my desk for long periods of time. I've been just as comfortable after 6-7 hours as I was after 5 minutes. I would highly recommend this to anyone needing a good office chair.
