I've heard them called "Step Tables" They are so versatile, they can work in almost any room of the home, living room, bedroom etc. You can leave them the original wood or paint them up!
My friend Stephanie found this awesome table at the Goodwill and gave it a new life with some paint and tape. !!LOVE!!
My Mom (Hi Mom!) found a pair for $10 each and gave them a fresh coat of paint. She uses them in two different rooms in her home.
And I rescued a pair from the side of the road and stenciled a pattern on them:
So if you happen to come across one of these little guys don't pass them up! Give them a new home, they will really appreciate it.
