The three layers of our mattress protector create a healthy and safe sleeping environment for your baby: • The first layer consists of a firm 3D structure that cannot be compressed with a flat hand. Thanks to this structure your baby is lying on top of an air layer, making sure your little one can breathe freely and doesn’t come into contact with bacteria or allergens. • The second layer retains moisture and keeps your baby dry. • The third layer is watertight and keeps the mattress dry. This layer also forms a barrier between your baby and the mattress itself. Our mattress protector is washable at 60°C and is available in all sizes.
