We decided we needed bunk beds.
So we built some.
We wanted them smaller than a twin, but bigger than a toddler bed (the crib mattress is the same dimension the toddler mattress.)
Ikea makes a special mattress size that is 10 inches longer than a crib mattress.
Just what we wanted.
We took some bunk bed plans (thanks Steve) and customized them for this specific, made-only-by-Ikea mattress.
Here's how it turned out!
Mike had a safety brief for the boys which included: proper mount and dismount, correct conduct on the bunk bed, an emphasis on anger managment, and a stern warning that the beds would become "un"bunked if they couldn't follow the rules.
