In case your son love cars but you don’t want to spend a rediculous amount of dollars of a fancy car shaped bed you can always make one by yourself. In order to save you time you can buy a Kira bed from IKEA and upgrade it. You’ll only need some plywood and paints for such project. Of course if you’ll equip the ed with a fire extinguisher, flashlights and some stickers it will look much better but all these things aren’t necessary.
