Bradley, it's just one of the $150-200 leather office chairs from Staples. I forget what brand it even is, maybe Lane? I believe that chairs are a personal fit, especially for those of us who carry extra pounds. What works for me won't necessarily work for you. In particular, I need something with good lumbar support. The biggest drawback is that it's a leather chair. That makes it less comfortable for extended use on a warm day than a mesh chair like the Aeron, but that's what you get for saving several hundred dollars.
If money were no object, I'd get a size B Aeron with the posture fit support, but then I'd also own about seven Alembics instead of two. Although they run $800+ new, I think you can find used Aerons through eBay, or better Craigslist, for about $500. The lumbar support add on is nice, but the less common posture fit is way better, at least for me.
