At the core of this baby mattress 162 interlocking coils create a firm foundation that will help your child get the best sleep possible. A great value, the two-in-one design of this mattress ensures it will grow with your child from the crib to the toddler bed-the infant side is the ideal firmness for newborns while the toddler side features a comforting layer of convoluted foam. A woven fabric cover with a waterproof backing helps keep the mattress warm and dry all night long.
