Query: Back feels better

For 17 years I used the same office chair thinking it was good enough. My back got progressively worse, mostly from age. This chair allows me to sit for long period of time in comfort with my posture at the desk nearly perfect. For me it was more than worth the money for something I use daily. Also, the other reviews mention the adjustable lumbar pad. I can't imagine not being able to make this adjustment and recommend this less expensive option.
