The idea is simple, cut a chair in half and mount it to the wall with a cleat. It's what we'd all do on a rainy day, right? Probably not, but we're glad someone else did so we have the inspiration to draw from. We can see this look working in an entryway for coats, slim kitchens for aprons or bedrooms (like they've done here).
Make sure you check out the full tutorial over at IKEA Hacker, it's more simple than you probably think it is and can be done in just a few hours. It's a great way to put to use not only IKEA chairs, but thrift store and estate sale finds — it's just so hard to pass up good stray chairs!
