A two step stool is one of those things that one must really have at home that will also serve several purposes. Of course, the obvious one is a step stool for high shelves and for hanging stuff like curtains and decor. When not in use, and depending on the design of the step stool, it can serve as a play area for your kids. It can even be a table for them.
Step stools can also serve as a nice place for pots of plants. And it's also great for when you're painting as the ledge will provide a sturdy place for paint cans.
