The Baby Delight Snuggle Nest Dream Portable Infant Sleeper in Sleepy Skies Fasion creates a comfortable and safer sleep environment for a baby within an adult bed. The updated design features two rigid, vented walls that are 8" tall. The bed length has been extended to accommodate longer babies while the width of the Snuggle Nest can fit comfortably in both Queen and King size beds. The tall walls are lined with a soft, breathable mesh helping to provide ample air circulation. And because we know little ones can be messy, the included sheet along with the sleeper's cover can be removed and machine washed. The Snuggle Nest quickly and easily folds in half and is ideal for use at home, as well as for travel. The inside can even be used to store essentials like diapers, wipes, and a change of clothes.
