This daybed and trundle is a great first bed for growing kids, plus a convenient extra space for overnight guests. The sleek, black metal frame features attractive geometric shapes on the headboard for a touch of vintage industrial charm. Underneath, the trundle bed pulls out and stores easily for sleepovers or just to make the most of a small space. This daybed fits two twin-size mattresses (sold separately). Plus, it even has a sturdy system of slats, so you can add your preferred mattresses without the need for a box spring.
