Pallet bed is an example of a project that can be quite simple to make or can require more woodworking knowledge.
It all depends if you just want to stack some prepared pallets and put a mattress on top or you want to build a proper bed from pallet wood.
And with some basic power tools like a jigsaw, circular saw, orbital sander or power drill you can put together a very nice project in no time.
I’ve collected some nice ideas of both. They look great and I’m sure you’ll find some inspiration here :)
