Product detailsA baby mattress topper is a 3 layer of padding that is placed on top of a baby’s crib mattress to provide an extra layer of comfort and support. It is designed to help improve the overall quality of a baby’s sleep. Baby mattress toppers can be especially helpful for infants who are prone to allergies or who have sensitive skin, as they can provide a barrier between the baby and the potentially irritating materials in the mattress itself. They are also a good option for parents who want to give their baby a more comfortable sleeping surface without having to purchase a whole new mattress. this topper has a waterproof under surface to protect the matress from liquid stain.Size:?( 28 x 52 )
