S.S.
We chose the trundle bed route with my children. My daughter's bed was very "frilly" and a pain to make everyday. So every night we would simply pull the trundle out, she would sleep, and I would pull up the sheet and push the bed under in the morning. So easy! Her trundle was one that would pop up to make a king size bed if we had overnight guests. My son's bunkbed trundle was a framed box that was perfect without the mattress for his Brio trains to remain set up, when he was older he designed an electric train set for the trundle.
