MySnuggly is a bassinet insert, carefully designed with features to help babies, and parents, get a little more rest. It is safe, tested and approved in all CPSC Children Safety Guidelines. The surrounding 3D air mesh allows air to flow freely. MySnuggly is installed on top of the bassinet mattress, providing a cozy, but still flat environment for the baby to sleep on his back, as advised by most safety standards. Opened and washed. Never used. Pet/smoke free home.
