I'm a big fan of Alton Brown and one of his major beliefs is that you should never buy a tool with only one function. While he's specifically talking about kitchen utensils, it's a philosophy that can apply to many other things -for example, your living room furniture. And with the Rise collection of furniture by Note Design Studio, you can skip having a separate coffee table and a couch in favor of having just one piece of furniture you can sit on and store your magazines or drinks on.
