    Sterling Endura III™ Waterbed PVC

    Sterling Endura III™ waterbed PVC was developed exclusively for Sterling Sleep Systems to meet all recognized performance and health standards established for waterbed vinyl in the US and in the European Community. We certify that Endura III contains less than 75ppm cadmium and meets all recognized limitations regarding heavy metal content.

    In manufacturing, and particularly when manufacturing waterbeds, material quality governs product excellence. No matter how skilled the fabricator a waterbed can be no better than the material it is made from. Endura III is formulated with the finest resins and plasticizers available for the application.  We engineered Endura III to be the best piece of material possible.

    Endura III™ significantly exceeds the California Bureau of home furnishings performance standards. A key indicator of material excellence is low temperature performance “cold crack test” results. Over the last 20 years we learned that low temperature performance is an important indicator of overall material formulation stability, not just a measure of how well the product will survive shipping during winter months. The California Bureau of Home Furnishings standards required waterbed material to pass a –20 F test, we engineered Endura III to exceed –35 degree F. We are not aware of any other waterbed material that equals this standard currently.

    We won’t share the specifics of the Endura III vinyl formulation, however we will tell you, you can’t buy better material for making a durable, long lasting, quality waterbed.
