Talk about a dream job! ... If the idea of work puts you to sleep, you need to send Casper Mattresses your application for a dreamy new job -- as a professional napper. The company has some pretty tough requirements, including "being able to sleep as much as possible," and "be able to sleep anywhere" -- including in stores during business hours. While Casper hasn't offered up a salary range for the part-time gig, they did provide a list of perks -- including a free mattress and the chance to show up for work in your jammies.
