1. Sleepovers are a childhood ritual, the source of great memories. Adding a trundle bed to your twin over full bunk bed makes even last-minute kid parties a snap. Just pull out the trundle and hit the sack.
2. Most trundles are really just big shelves. For handy storage space for toys or blankets under twin over full bunk beds with trundles, you can take the trundle bed mattress out. Insta-drawer.
3. When your kids have a friend over and it's time for bed, the added trundle bed beneath your twin over full bunkbed will keep giggling, poking, fighting, and squirming to a minimum. No roll-over casualties from sharp elbows. Kids will sleep better, and thus so will you, and you will all be more cheerful at breakfast.
4. A twin over full bunk bed with trundle is fun for kids to operate. They like to help. Bonus feature: sheets and blankets have to be tucked in before the trundle can be pushed in or out, so it gives them one more reason to make their beds.
