RH Baby & Child's Cotton Voile Play Canopy:A little imagination goes a lot further when it's accompanied by our hanging canopy, which transforms any nook into an enchanted enclosure just perfect for play.
I like this. Center a rod attached to the ceiling and aligned with the middle of the mattress. Hang and drape a measurably long length of fabric into a canopy. It gives a tent effect. Kids love that. Plus, you can add and remove on a whim.
