Unexpected overnight guests can be even more of a challenge when you're living in a small space. If you don't have room for an extra bed, don't feel that a pull-out sofa or futon are your only options. How about a slightly oversized arm chair? We spotted the Oxford Twin Sleeper, in an old issue of Real Simple while doing some spring cleaning. The Oxford Twin Sleeper opens up to reval a five-inch thick twin bed with a locking headrest. It comes upholstered in a stain-resistant microfiber, in "Dublin Aloe", but other colors can be custom ordered. It's $999 and measures 55 by 37 by 35 inches. Available from Crate&Barrel.
