When having to deal with a small room for your son or daughter, a loft bed with a desk underneath provides ample sleeping and working space without taking up too much room. Some loft bed designs even feature a closet or bureau for extra storage. Just make sure beforehand that when you order the loft bed, you know the measurement of the height of the bed and the room since you want to be able to sit up in bed without hitting your head on the ceiling.
