Build your own toddler bunk beds using 2x4s and crib mattresses.

It's hard to find a toddler bunk bed system because of safety concerns.  But families still may want a toddler bunk bed - children can sleep on a crib sized mattress well into school years - plenty old enough to use a bunk bed. 

So people everywhere are building their own toddler bunk beds (but not necessarily for toddlers) to meet their family's needs.

Like all bunk beds, the top bunk should not be used by children under six.  Build and use this plan at your own risk.

Step 1

Build two legs sets by screwing the rails to the legs with 2 screws per joint.  Use glue at joints.

Because of the finished size of this project, you may wish to finish assembly in the room it will be used in.

Attach end rails with 2 screws per joint and glue.

Step 3

Attach ladder rungs with 2 screws per joint as shown.

Do not leave less than 9" spacing in between ladder rungs (neck entrapment safety)
