We loved our previous Staple desk chair and purchased this to replace it when it finally wore out. We were really surprised at how sturdy the chair is! The roller unit is very strong and the base of the hydraulic is actually made out of metal which was unexpected at this price point. My only complaint is that I wish the back was just a little bit higher but that is probably just personal preference. I am 5'4" and my husband is 5'10" and we both find the chair very comfortable.
The chairs are used in meetings therefore they have different people sitting in them every meeting. They are very comfortable with the high back you can rest your head on the back of the chair. The high back also gives great back support. They were also easy to put together which is always a plus. I am very happy with the chairs and the price was very reasonable. I would recommend the chair to anyone interested.
