The innovative Dual Core mattress provides a firm sleeping surface to the newborn as well as an excellent tailored sleeping surface for the growing child. The child's weight can change by a factor of three in the first year alone and the Dual core overcomes this problem by providing two cores in one. The firm newborn side has orthopaedic foam and coir with a highly breathable top cover. The waterproof reverse side of the top cover protects the inner layers of the mattress. Once your infant grows to a toddler flip the mattress to the tailored support side which has micro pocket springs and also comes with a removable and washable cover to maintain utmost hygiene standards.
