My parents have a home in Florida that has been a great meeting place for our family. When all the grandkids are in town we have a room just for them. The only problem is that, until now, we’ve been living with one full bed and three twin mattresses that sat directly on the floor. I decided it was time to knock out some bunk beds for the kids and this time we went for a built-in look. For this bunk we used a full size mattress on the bottom and twin above it. We opted for a lower bed to maximize the space between. Read on to see exactly how we did it.

An upgrade here would be to swap the upper slats for a sheet of 3/4″ plywood. This will give you a more finished look from below.
