A bunk bed desk combo makes a great place for study and sleep. However, that shouldn't be happening at the same time! In order for kids to develop good study habits, they need a designated place to study.
We have a lot of designated places where we do things every day that we ordinarily do not think about. We have places to eat, watch TV, do the laundry, cook, talk on the phone, relax, exercise, and get ready in the morning. If we didn't have these designated places, then our lives would probably fall apart.
These designated places make us more efficient and focused in our daily tasks. If your child doesn't have a place to study, then how is he/she ever going to form good study habits? With a desk and bed combined, kids will still have lots of room for playing and whatever else they want to do in their bedroom. But they will still have the all-important places for sleep and study, making it a perfect choice for some kids bedrooms.
