In general, a wacky design like Hugh Hayden's Tennis Ball Chair would head straight for the Love It or Hate It box. But I think it's an innovative and eco-friendly repurposing of an object that's not meant for interiors. The chair apparently bounces and jiggles just like a tennis ball does, without losing shape, which is engaging and fun! It's definitely a modern design, but I'd like to see it in a traditional home — I'm thinking a blue and white Hamptons cottage or a pale place like this cool California home. It would perfect for a family with kids but also might be just the thing to get grownups to lighten up every now and then.
