Is there such a piece of furniture as a wide or double day bed, or a bed that has a tall cushioned side to it? I have a tremendous amount of trouble sleeping in a regular bed. I sleep so much better on a sofa, where I can put my back to the back of the sofa, if you get what I mean. Pushing the bed to the wall and sleeping against the wall doesn't really help. Any suggestions on a piece of furniture that might be suitable would be very appreciated!
