This may sound like a no-brainer, but rearranging the furniture in a tween's room and adding a few inexpensive accessories may be all you need to do. Consider the different ways that your tween now uses a bedroom. It's his or her personal study space, lounge, dressing room and sleeping quarters. With the furniture you have, divide the room into those different functional areas, almost like decorating a studio apartment.
For instance, if the desk is next to the bed, separate them. Move any televisions and entertainment devices into a corner to delineate between a workspace and a chill-out zone. Suspending floor-length curtains can cordon off sections for added privacy, which your tween will treasure. Once your furniture layout is complete, you'll know if you need to buy any extra lamps, seating or other dècor.
