With a full motion water mattress the water flows unimpeded throughout the entire mattress.
This is the water mattress that built the Waterbed industry, and still has a large following today. Full motion is preferred by those who enjoy the sensation of total flotation......
Reduced motion mattresses are achieved through the addition of interior fiber inserts that impede waves and confine the water to smaller areas.
Wave reduced mattresses are preferred by consumers who desire the benefits of flotation sleep with less movement. The wave reduced designs are available from 40% waveless to 99% waveless or no motion.
