If you have more than one boy and they share a bedroom, then this design is an easy solution. You can offer each boy their own individuality by using the same pattern comforter sets, but in different colors.
Paint a pair of twin beds a toasty brown, and add a floor lamp beside each bed. Cover the shades with matching fabric or go for a similar pattern with contact paper.
Give each boy a fun storage solution with a footlocker or trunk positioned at the end foot of the bed; these can be purchased cheaply on yard and garage sales. Don't forget to add a nightstand painted the same color as the beds; by placing it between the bed, the boys can share and you only have to buy one.
