Q:The cushion is usually in the housing which parts
Cushion is generally at the base, looking for the use.
Q:Is the raft cushion waterproofing full of the cushion?
Base cushion waterproofing is not contact with the soil (Ying water) to prevent water into the cushion, but in the cushion and the base of the bottom of the contact, in fact, is the basis of the bottom of the waterproof.
