Dream On Me 2-in-1 Portable Folding Stationary Side Crib for just $106.40 shipped (regularly $219.99)!

Perfect for smaller homes, or for keeping at the grandparent’s house, this Dream on Me crib has a unique hinge system that allows it to fold flat for storage. The mattress has two height settings so it’s higher when babies are little and then you can lower it when they are bigger.
Note that it does include a 1″ mattress pad, but most reviewers mention it’s more if you’re using it as a playpen and you’ll want to grab an actual mattress if a baby is going to sleep in there every night.
