The memory foam mattress with a profiled HR core is ergonomic, relieves pressure points, and allows for proper bone development. This mattress has a different texture on each side, and therefore two recommended usage stages: the first for use during the baby's initial months (up to 8 kg), as it allows for optimal head adaptation; and the second, recommended from 8 kg onwards, in which the smooth HR foam provides the firmness necessary for the baby's proper bone and muscle development. The (removable) padded cover also has two sides with different fabrics: one side is made of TENCEL fabric, which is warmer for winter, and the other, made of AIRTEX 3D mesh, which allows for greater air circulation, ideal for summer.
