Consider the design motif of your daybed. For example, a traditional room might have a wooden bed frame or one with brass. Coordinate the look with the room's theme. For example, if your child loves trains, paint the bed frame to resemble a boxcar. If he prefers outer space, paint the daybed black and accent with stars in glow-in-the-dark paint. For a jungle-themed room, wrap the frame of the daybed in artificial vines or hang stuffed animals from the sides.
The bed is the focal point of a bedroom, which makes the bedding you choose important to the room's design. Most daybeds are outfitted with twin-size mattresses, so standard twin size flat and fitted sheets are appropriate. However, because the daybed is positioned against the wall, special consideration is required for the comforter. You will need a duvet designed with short sides that can tuck into the interior frame of the daybed and not hang over the sides. Accent with pillows and stuffed animals along the length of the bed and on the sides.
A trundle bed has a collapsible bed frame and mattress that slides underneath the daybed during the day, but pulls out at night to provide an extra sleeping area. If two boys share this space, this is a smart option for providing enough beds while also providing space for the boys to play. Hide this space under the bed with a three-sided dust ruffle designed to fit onto a daybed.
Instead of a traditional daybed, consider some similar options for use in your child's room. For example, a futon is a piece of furniture that converts from an upright sitting position to a sleeping position at night. Also consider sofa beds that hide mattresses in the seating for the furniture. A Murphy bed is another option. Murphy beds are built into the wall and folded up during the day, then pulled down at night for sleeping. This frees up plenty of space for work and play areas.
