Triple Bunk Bed with Trundle

Triple Bunk Bed with Trundle.

The one in the photo above has me in love. But as storage space we are not going to walk over, the idea of ​​putting a bed that has room to store things under, also tempts me. My question is, is not it to waste space if you have a few square meters of room? Walls papered with floral motives and instead of putting bed, here we have preferred to put a bunk bed with trundle in an armchair, so when nobody sleeps it looks like a room and we have the possibility that another person sleeps in the trundle bed.
