Is A BunkBed Suitable For A 16 & 14 Year Old To Sleep In?

It does sound a wee bit short, but I'm sure that it will be fine for you and your sister. I would suggest that your wee sister takes the top bunk, as she will probably be a spot heavier than you. If the bunk bed turns out to be designed for wee teeny folk, you should feel safe that she is on the bottom bunk and has no chance of "falling through" and landing on top of you!!!!
