Filling your waterbed

April 26, 2006

 How deep should a watermattress be filled? In my quarter century of experience as a  waterbed expert, this has been the most insideous problem facing the industry. First of all, water cannot be compressed. It is physically impossible. That said, overfilling a watermattress can only be problematic. It won't get firmer, it will get rounder. It is cut to be filled to a certain depth (usually 7-9"). Exceeding the recommended depth will:

  • Stretch the vinyl and weaken the seams
  • Increase electrical consumption (more water to heat)
  • Stress and warp the sides
  • loosen screws and break brackets
  • Cause undue stress to supporting structures
  • Make it difficult to tuck in sheets and bedding
  • Make it LESS comfortable

    An air mattress will get firmer as you add more air, because air beds are filled with a gas, not a liquid. Gasses will compress. liquids cannot.

  Underfilling is the lesser of two evils. It causes bottoming out on the deck, but that can lead to overheating the heater and damaging the vinyl.

 I have seen properly filled waterbeds last 20+ years. The best advice i give to my customers on filling a waterbed is to lay a broomstick, or similar device across a wide corner of your hardside or softside waterbed at it's lowest point. When the water level begins to lift the broomstick off of the wood or foam frame, shut off the water. Adding more water is of no benefit to you.

Now, disconnect your hose from the sink, and as you coil it, hold it higher than the bed to let it drain into the bed. after that, couple both ends of the hose together to prevent spillage.

 Next is the burping process. this is easy if you didn't overfill your watermattress. Gently use the broomstick to influence any trapped air bubbles to move toward the open valve. You can usually see them in sufficient light. Lay the stick flat on top of the mattress like you are floating cement, gently pushing the air towards the valve.  Repeat this a few times. The air will easily vent out until there is no more splashing noise inside. This should be done again as necessary. The best time to do it is when you change the sheets.

Before replacing the cap, you now should add the waterbed conditioner. This will be the subject of the next blog.
