This extra-long twin storage bed is 5" longer than a standard twin making it ideal for teenagers and college students. Underneath the bed, 3 large storage drawers (20" depth) that run on smooth running metal drawer glide add a great storage solution. The 3 drawers are located on one side so that the bed can be positioned left or right to suit any bedroom layout.Wood slats positioned lengthwise distribute body weight evenly and take the place of a box spring, so the bed needs only a mattress. This product is made from composite woods with overlay laminate and plywood slats. Detailed and easy-to-follow instructions are included.
