Hardside Waterbed Mattresses

Sterling Sleep Systems has been building some of the finest Waterbed systems for over 3 decades.

While all hardside waterbed frames are different, we would like to show you the best way to set up your new Sterling Hardside Waterbed, including some tips that you might not have thought of, to help ensure your waterbed will remain comfortable for years. Doing these few extra steps will help prevent leaks, and even slightly reduce your electricity bill. Remember, the best thing you can do to protect your waterbed is to add one of our high-quality pillowtop systems. This will help prevent punctures or cuts in the plastic and help retain the heat. And don't forget to add a water conditioner every year.
