Don't be misled! Waterbeds are not too heavy for upstairs floors - Nor do they burst and flood the house! In fact, modern waterbeds exert less pressure on the floor than a conventional bed, and the durable vinyll mattress provides excellent service for over 10-years before it needs replacing! How many conventional mattresses offer you that? PLUS - You get TOTAL body support, whatever your sleeping position, 100% of the time!
