I thought the chair I replaced with this one was excellent when it was new but it didn't come close to comparing with this chair. I'm more than a little surprised that you can get a chair of this quality at this price. I spend a lot of time sitting and had developed a pain in my left leg that has lasted for more then a year. Within 6 hours of sitting in this chair, the pain disappeared, and it hasn't returned. I can't believe the construction of this chair. Additionally, the chair shipped the same day and had a weekend not gotten in the way I would have had the chair in two days. Terrific service!
