Our take on the SlumberTime Naturally 4-Inch Mini Crib Mattress

The SlumberTime Naturally is a 4-inch mini crib mattress with a fiber core made from recycled bottles and a cotton-blend cover that is soft, breathable and waterproof. It fits most mini and portable cribs, not standard cribs or Pack 'n Plays. The thin, firm build suits compact mini cribs where a full-size mattress won't fit. Against rival mini mattresses, it stands out for the recycled-fiber core and waterproof cover rather than coil support or a two-sided infant/toddler design.
