How much does a waterbed weigh?
A hardside (wooden framed) waterbed weighs approximately 300 lbs per foot of width. This makes a queen sized waterbed weigh approximately 1500 lbs. A softside waterbed will weigh approximately half of this amount because of the reduced water volume. A softside waterbed with tubes will be the lightest of the waterbeds with the tubes weighing approximately 40 lbs each. Since the weight of a waterbed is distributed over a fairly large area, the per foot weight is usually not a problem for any home built to code.
