Pallet as a bed frame 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.
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.
In most basic projects all you need to do is to put some pallets on one level, join them using steel flat brace brackets. Then if you want your bed to be higher add another level of pallets or use a thick mattress.
For a fancy look put some LED string/strip lights underneath the bed. These are easily available on Amazon and you can choose from a wide range of colors. For those of you who want some diversity go with a multicolor set that allows changing color to whatever you want with a push of a button. I even found some LED strips that work via Bluetooth and you can sync them to music or Alexa(!)
I’ve collected some nice ideas of both. They look great and I’m sure you’ll find some inspiration here :)
