Closed cell foam is a relatively strong medium density foam. Unlike other types of foam or open cell foam, there are no pores that allow any liquid or air inside. This is done by trapping gas bubbles within the foam during the curing process. This makes the foam stronger and denser than standard polyurethane foam.
The primary issue with using closed cell foam is the density. This makes for some uncomfortable cushions. One way to get around this is to encase the foam in batting which will make it more comfortable and then use waterproof cushion covers. Although these are used as support for mattresses, only a limited amount is used in order to maintain comfort.
