The U.S. Waterbed California King 3000L is a hardside waterbed mattress featuring 90% waveless technology and an integrated 300-W digital heater.

The United State Water Mattress Queen 3000L provides semi-waveless performance, reinforced corners, safety liner, and a full-watt heater with digital control.
