When manufacturing waterbeds, material quality determines product excellence. Endura III is formulated with the finest resins and plasticizers available for waterbeds.
Sterling Endura III waterbed PVC was developed exclusively by Sterling Sleep Systems to meet all recognized performance and health standards established for waterbed vinyl in the US and in the Europe.
Endura III significantly exceeds the California Bureau of home furnishings performance standards. 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 requires 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.
