What’s more important for a twin bunk bed than staying safe and saving space? Youth furniture that stays flexible to life’s changes is great, too. With the White Wood Twin Over Twin Bunk Bed, you get all three. Stay safe with a floor bunk made for wild sleepers and top guardrails made for 6-year-olds and up, both made of solid wood. A fixed ladder keeps it compact, while the transitional shiplap design keeps it clean. And the flexibility? When life changes, break up the bunk into two twin beds. Includes the twin bunk bed frame with bed slats; no box spring necessary. Requires two twin mattresses; not included. Assembly required.
