Firm mattress assures baby the right sleep support. With its heavy gauge foils and proper corner support, the baby is safely tucked and well rested on the crib. The mattress comes with a vinyl cover that protects it from dust mites and liquids. It is also treated with a Fireblocker that makes it really safe for the baby. The mattress also has a vent, thus making it a cooler sleep space.
