An 11 cm thick mattress with individually wrapped pocket springs enclosed in a generous layer of pressure-relieving foam. Here your baby sleeps safely and comfortably – so you can also sleep peacefully. A crib mattress where you can see and feel the care in every detail, from the well-ventilated construction to the durable fabric and detailed stitching. The outer cover is easy to remove and is machine washable at 140°F (Hot). A fixed inner cover increases the fire safety of the mattress and makes it easy to put the outer cover back on after washing. It also prevents children from putting mattress contents in their mouth. Pocket springs allow air to circulate freely in the mattress core and provides your child with a well-ventilated sleeping climate with an even temperature. The zipper of this mattress has a little pocket where you can hide the pull tab from the hands of curious children.
