This chair replaces a 20+ year old Areon chair. It is doing the job with only minor compromises; multiple axis of adjustment for armrests. Other than that its super well made was well packaged and with the excellent instructions was a 15 job to assemble.
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.
