Purchased these bunk beds when downsizing from house to apartment. The perpendicular design works nicely to maximize space, and I love that the full bed is on casters. This not only makes it easier for the older child to make her bed every morning, but allows for the full bed to be moved to another room, leaving space for a desk and chair below the twin.

Pros: Clever design, attractive finish, components can be used separately as loft bed and full bed
Cons: Assempbly instructions were somewhat confusing -- and I'm an engineer
