I used to believe that placing a bed in the corner of a room was a problem. The task of making the bed can be more difficult, and it can look strange pushing furniture to the edges of the room. But sometimes, when a room is especially small or if you're trying to fit two twins into a small shared children's room (or guest room) it's just a necessity. Here are some beds in corners that make me want to find a way to be stuck with this "problem!"
The headboard is key is several of these examples. With it wrapping the corner, a cozy spot for settling back is created. If a headboard isn't in the cards for you, try a collection of pillows as shown in the first example.
