New York City is one of the few places where it is socially acceptable, and even encouraged, to rummage through curb-side trash. There is no shame in this. All New Yorkers know someone who has found a treasure on the curb: a rare first-edition book, say, or a good-as-new couch. The question is inevitably the same: “Who would throw this out?”

For the next two days, Blu Dot is honoring this cherished urban pastime with the Real Good Chair Experiment. In collaboration with mono, Blu Dot will place chairs all over the city, free for the taking. But there is a slight catch: most of these chairs, valued at well over $100, are GPS-enabled. Blu Dot will use the devices to track the chairs’ voyage for a documentary debuting this December, to mark the one-year anniversary of the company’s Soho store.

But don’t worry: GPS or no, if you happen to stumble across one of the chairs, it’s finders keepers! The rest of us will have to be content to track the chairs’ progress at realgood.bludot.com.
