Twin Size Convertible Wooden Bunk Bed White Finish

I have to say that the bed looks great. My daughters love it. But the mattress support comes with 6 wood pieces per bed (12 total), and they are very thin. I did not feel safe with my 7 year old daughter to sleep in the top bunk, and she is avarage size. We went to the home depot and bought some more support pieces made out of thicker wood. But other than that, the bed is very nicely made and looks expensive.
