Waterbed Bladder Types

Free flow waterbeds use original design with the one big bladder that creates waves with even a slight movement on the surface. The floating feeling was cherished by some but detested by others that complained about lack of support and continuous, disturbing motion.

To improve the motion transfer and increase firmness, manufacturers began implementing fiber filling – placing motion dampening fiber materials into the bladder. By adding larger amount of fiber filling, manufacturers improve motion separation and increase firmness, offering semi-waveless, waveless and ultra motionless mattresses.

Another way to improve motion separation and support in waterbeds is to separating the main bladder into smaller compartments. Just like with air chambers in air/dial beds, waterbeds used the same design with two separate chambers or dual bladders, allowing different firmness and temperature on each side.

Another innovative design uses bladder that is further divided into many small compartments. It allows water to flow slowly and gradually through tiny holes between compartments, thus providing firmer support and improved motion separation.

Yet another design features independent vertical tubes that can be easily filled and drained. Tubes can be filled up to different level on each side of the bed providing desired firmness level. Vertically lined up tubes offer reduction in motion.
