This one is for all you chair geeks / design nerds out there. (I'm one!) While we were living in Florida in 2015, I picked up a bargain chair ($10) that I nicknamed 'The Batman Chair' as it looked like the seat of the Batmobile. After identifying it online as a Jerry Johnson Sling Chair I dug a bit deeper and found the design patent, including it in my listing.
