Enjoy the original waterbed "feeling" with this free flow design, which doesn't compromise on features, namely:

• Overcut 0.6 mm thick special vinyl: minimizes stretching and maximizes longevity while conforming to and supporting our body's contours.
• Double fill valves on two-person sizes make filling and draining easier.
• Simple 8 cm overlap seams: at the corners require fewer welds, while placed at the middle of the sides make stress on them symmetrical. In both cases this leads to increased reliability and durability compared to traditional designs.
• Black mattress material doesn’t make a separate black bottom layer necessary for more effectively transmitting the heater's warmth.
