I write to you from an Aeron chair I acquired from a failed startup in 2001. I've gotten almost 16 years out of it so far, and I spend at least 8 hours a day 5 days a week in it. I've spilled coffee and food on it, and was able to clean it with just a bit of Dawn detergent and a hose.

I'm not willing to compromise on my health or my working conditions. Too old for that. Spend money on things that make your life more comfortable or easier when you can.
