I thought this was a great idea. When the kids get sick of the trampoline, turn it into a day bed.

This is a fantastic idea!
This is similar to the hanging pallet bed (which I love), so was really exctied to see this spin on the idea with the trampoline. A small trampoline could possibly work really well too. Plus it would be super comfy.
