FAQ

How much headroom does a bunk bed need?

It depends on the model. Compare the listed overall height with your ceiling and leave generous space above the top mattress.

Can a bunk bed be split into two beds?

Some designs can, but not all. Look for a listing that states the frame converts to two beds and check what extra parts are needed.

The Short Version

Measure your room, confirm the mattress size and read the maker’s weight and assembly details. The best bunk bed is the one that fits your space and your household’s needs.
