Maintenance of your waterbed

A waterbed is a very comfortable sleep system with the best features in terms of hygiene, because of the fact that the mattress can be cleaned. Dust mites and allergies can be avoided this way.

In return it requires a little effort for maintenance, a couple of hours per year.

Maintenance mainly comes down to:

  • add conditioner
  • wipe the mattress with vinyl cleaner
  • check the water level
  • extract excess air if necessary
  • wash the cover
Conditioner for waterbeds

Because the tap water quality is not optimal everywhere, to prevent algae growth and keep the water fresh, add a bottle of conditioner every six months. (A small bottle is good for twice-yearly addition, the larger size can be used once per year).

We recommend to follow the usage guidelines. If you do that, basically, the water should never be replaced.
Use a waterbed conditioner with an approved registration. It is important to always use the same brand and type of conditioner because some products are not compatible. The use of different types or adding conditioner too late can lead to the formation of unpleasant odors. The water sometimes needs to be replaced then.

To open the filler cap of the mattress, pull it gently out of the mattress by the tabs and with a wiggling movement out of the mattress. Unscrew the cap and remove the inner cap. Keep the fill opening lightly pressed into the mattress so that no air can come in. You can now add the bottle of conditioner. To close again, see below: air extraction.

Vinyl cleaner

Maintain the outside of the water mattress regularly (every three months) with vinyl cleaner by spraying it on the mattress and wiping with a dry cloth. Don't forget the sides (between the mattress and the safety liner)!
ATTENTION! Use vinyl cleaner with an approved registration. Never use ordinary soap or household cleaners.

Check the water level

When adding conditioner or cleaning the mattress you should also check the water level. The water level is a very important aspect of a water mattres.

The PVC film of the water mattress is waterproof of course. However, PVC is not 'damp proof'. Because of the heat, there will always be a small amount of water that evaporates through the wall of the mattress.
That's why it is very important to add from 10 to 25 liters of pure water each year. (Half of that per mattress in a DUAL system.) The exact amount can not be given simply because it depends on the size of the bed, the temperature, the temperature in the bedroom, the frequency of airing etc... As a rule of thumb, the water level should be circa 1 cm under the top of the foam edge. Refilling is easy with a household funnel and a clean water bottle. Normally, pure and cold water suffices. We recommend using water that has not been treated by a water softener.

Air extraction

During the first weeks after the installation of the waterbed air bubbles may form. (Dissolved gases in the water slowly release.) You can hear it for yourself when you need to extract the air. Also, at the subsequent addition of conditioner or water you may need to pump out excess air.

Removing the air is best done by two people, but you can also do it alone.

To open the filler cap of the mattress, pull it gently out of the mattress by the tabs and with a wiggling movement out of the mattress. Unscrew the cap and remove the inner cap.

Screw the air extractor pump on the filling opening.
The air present has to be driven in the direction of the filling opening. Work from the headboard to the filling opening. This is best done by moving a tubular object gradually in the direction of the filling opening. Alternatively, one can lay transversal on the bed and then roll in the direction of the filling opening.

Pushing and wiping with the hands and thus gradually move forward is also possible.

Then pull the filling opening with the pump up slightly so that the air can accumulate under the cap. (Ideally, by a 2nd person.) Pump the air out until water appears in the transparent portion of the filling cap. If necessary, repeat the entire procedure from different angles.

To close, unscrew the pump. Press the filling opening lightly into the mattress until the water rises to the top of the transparent part of the filling opening. Place the smaller inner cap to close. Screw the outer cap back on.

Press the whole filler cap back into the mattress.

Wash the cover

While sleeping the cover absorbes the perspiration produced by our body. Daily airing lets the perspiration evaporate and is therefore important. The warmth of the waterbed speeds up the process.
Just as the linen you can regularly clean the cover. This can be easily done in the washing machine. Pay attention to the washing instructions.
Although some types of cover are suitable for this, boiling (95°C) is no longer required with the modern washing powders. Washing at a lower temperature is equally good and better for the environment.
The washing of the larger sizes cover can be a problem in an ordinary washing machine (5-7 kg). Therefore, most water sleepers in this case, choose a mattress cover in two parts with a middle zipper. Should you not prefer this, you can usually find a launderette.
