A question that many people may ask when choosing furniture for their home is whether you can use furniture meant for one room in another. The answer is yes, you can use whatever furniture you like in whatever room that you like. It is your house! A breakfast nook set might be a great addition to a play room or patio. I have a large playroom in my basement. It is a very large room and I have added a breakfast nook set to one alcove of the room for the kids to use for drawing, playing with toys that need a hard surface, or to have a snack. It has been very convenient. Another place to use breakfast nook furniture is on the patio or deck. Just be careful about the materials that you choose. You want to make sure that your furniture is weather resistant or meant for indoor/outdoor use.
