A typical full-sized mattress measures 54 inches wide and 75 inches long. Add a few inches to those dimensions for the bed frame, headboard and foot board, and a small bedroom will be filling up fast. Fortunately, if your room is 10-feet-by-10-feet, that leaves you about 3 1/2 feet of free space in one direction and 5 1/2 feet of space in the other direction -- plenty of room for a dresser. By arranging a small room for optimum convenience, the room will feel less cramped.
Push the bed to one wall. Which wall you choose should be based partially on convenience and partially on practicality. Some areas may be eliminated based on the fact that the bed would be blocking the closet or the door. Consider where you want to orient your head in relation to a window. You may not enjoy being blinded by intense sunlight streaming straight through the window in the morning, but you might not want your head under a window either because of draftiness or not being able to lean up on pillows in bed.
Push the dresser up against the opposite wall, if possible. In a 10-foot-by-10-foot bedroom, there will be more room next to the bed than at the end of it; putting it at the foot of the bed is an option, but it's easier to bend down and get drawers open and shut with plenty of room behind you. A tall dresser may be easier to fit into a small room because it has a smaller footprint and may be able to fit against the wall next to the doorway more easily. On the other hand, if there is a window opposite your bed, a long, low dresser that fits under the window would be appropriate. Try to avoid placing the dresser behind the door if you can, as you will soon tire of the door banging against your dresser every time you open it, which is annoying and could ding the dresser or the back of the door.
Pull your bed away from the wall a bit if you have a few inches to spare once you have the dresser placed. This makes the bed less of a hassle to make, helping you feel less cramped. Open and close the dresser drawers, the door, the closet and the windows to make sure everything in the room is accessible and unobstructed.
