Only the Top white portion of The O Mattress™ cover is washable.  To wash the cover, unzip the cover using the zipper located on the side of the mattress.  Wash with cool or warm water on a delicate cycle.  Hang to dry or tumble dry on low heat.  Do not wash the black base portion of the cover.  To prevent colour transfer from other clothes, only wash the white cover in its own separate load.
