This is the first office chair that I have purchased in the last 15 years that is hard to put together and has come loose at the arm level with the back. The upper screws do not fit properly nor tighten up and the lower screws are coming loose. Not happy with chair. It needs to be replaced or a tech come repair free or bring replaced and put together.
After using the chair for just a few days I found it to be very uncomfortable for me at least because I am short and relatively old. I personally did not fit well in the chair as I am about 5ft 6" my body could not comfortably reach the back of the chair and the back leaned to far back without the ability to adjust forward. I would have liked to sat in the chair prior to purchase but unfortunately Staples had closed most of the stores in my area. I did find 1 store at University in Bradenton FL about 15 miles from my home but that store did not have one in stock or on the floor.
