Poor Fred Flintstone… Worked all day and came back home to ruthlessly uncomfortable stone furniture! I’m sure he would have loved one of these stone-mimicking foam stools. Designer Matthijs Kok did a spot-on job of molding soft PU Foam to look like a chunk of rock. Don’t let your eyes fool you, the stool is as soft as a baby’s backside. And with its three chrome legs, it looks like something the Flintstones would receive from the Jetsons!
