House Beautiful is playing hide-and-seek—with chairs. The magazine’s fourth annual Chair Chase is taking place in Los Angeles today and tomorrow, with designer chairs being positioned around the city up for grabs. They’re all black-and-white in a nod to old Hollywood. Best yet, they’re free for the taking, but only if you can locate them with the clues being tweeted at @housebeautiful and tackle trivia questions about the chairs from information design bloggers that are in on the game have been posting about each chair. The chairs retail for up to $4,000 and come from manufacturers including American Leather, Room and Board, and Crate & Barrel. The chase is on!
