This is the second one I have purchased. The first one lasted 2+ years with 10 hour days. The seat padding (foam) in all chairs slowly deteriorates but this chair outlasted my last 3 expensive high quality chairs by a long shot. This chair is often on sale so wait until then.
I bought a protection plan when I bought my chair well worth it. My chair had some issues and I was able to get a replacement. It is a totally different chair but I like it better than my original chair.
