The mattress is encased in a protective cover which is removable for machine washing at 30°. Just pull the zipper to open the cover.

The mattress foam can be washed with plain water (with a sponge or in the bathtub).

Please note: we have deliberately removed the zipper attachment. This is so that we can meet a requirement of the standard which requires that the child doesn’t have access to the foam. So when you want to remove your mattress, you can use a small metal paperclip-like object to help you.
