- Progressive Rate Spring
- Most Waveless
- Tethered Motion Control
- Five Comfort Layers
The tethered wave control system restricts the movement of each layer to minimize wave action. That means you can get to sleep faster and move at night without disturbing your sleep partner.
The Progressive Rate Spring is positioned in the lumbar area to support the part of your spine that naturally curves inward, relieving sleep-related and posture-related back pain.
Traditional waterbeds create a gap between the water bladder and the mattress frame when the sleeper rolls towards the side. We reduce this action with additional support at the edges.
