A Softside mattress has the tremendous advantage of conforming to your body's shape immediately. Unlike a conventional bed, it does not create the uncomfortable pressure points. Instead, the water mattress offers a semi-weightless environment in which your body (being 90% water) naturally floats. This results in a night of more restful sleep without the tossing and turning that experts say takes place to relieve uncomfortable pressure. A Softside mattress also pampers you with therapeutic warmth. You experience a mental sense of "letting go" as the soothing warmth engulfs you, and because the mattress is already at body temperature, your heart doesn't need to work as hard to heat you and your bed.
