Frequently asked questions

The 5 explicit benefits that sleeping on water offers are:

  • full body support
  • a pleasant comfort without pressure points
  • relaxing warmth
  • a hygienic sleeping surface
  • long life span

All these points are discussed in several of the following questions.

The oldest report of the use of waterbeds dates from more than 3000 years ago. In those days, the Persians slept on goatskin waterbags heated by the sun. The next development came in 1851 when the British doctor Dr. William Hooper recognised the benefits of a pressure-free waterbed surface and introduced them for the treatment of certain medical disorders. He designed and patented a simple rubber water mattress. Towards the end of the 1960s, the American, Charles Hall, refined this concept and by using modern materials and production techniques created the PVC mattress that we are now familiar with.

Charles Hall, Dr. Cooper and all their predecessors used only water, the most natural substance, as support for the body. The water acts as an anti-gravity device. In that state of reduced pressure and apparent weightlessness, our body can relax more deeply. So, by sleeping more deeply, we can increase the rejuvenating action of our sleep. That, in a nutshell, is what sleeping afloat on a waterbed is all about.

Essentially, there are three types of waterbed: hard-side-, soft-side and boxspring waterbeds.

The hard-side waterbed is the original type. With this now somewhat outdated design the water mattress lies directly in a strong wooden surrounding that provides lateral support. The whole rests on a bottom plate, which is supported by a socle with weight distributors. Between the mattress and the wooden bin, there is a safety lining that can catch the water in case of a leak.
We do not produce hard-side beds, but you can contact us for a new hard-side water mattress, safety liner or cover.

The modern variant of the waterbed is called soft-side. In this type, the water mattress is laterally supported by a foam edging. In our waterbeds this foam edge is further divided into a lower, fixed edge and an upper hinged foam rail allowing the cover to move even better with the body. The support from this foam edge ensures that a soft-side waterbed can stand alone or can be fitted into an existing bedframe.

Our latest achievement is the boxspring waterbed. This type of waterbed combines the advantages of a soft-side waterbed with that of a box spring. The water mattress lies on a sprung base for added comfort. We produce our boxspring waterbeds under the brand name Fenix Bed System.

Our products are available in a wide range of standard sizes. Due to the fact that we produce everything ourselves also 'made to measure' is no problem.

Our Fenix waterbeds are free-standing. Our classic waterbeds can also be placed in an existing bed frame without problem. You give us the exact internal dimensions of the bed frame and we produce a waterbed with the perfectly fitting size.

A waterbed supports your back in the best possible way. When you lie on a water mattress, the water moves so that it takes up the precise shape of your body. The bed doesn’t sag, but adjusts precisely and instantly to your body, whatever your weight. These properties, combined with the dramatically reduced pressure on the surface and the wonderful warmth, provide the ideal support for your back.

Waterbeds have many medical benefits. The waterbed was, after all, already in use in the medical world before it became a commercial success on the open market. It was discovered that the state of apparent weightlessness helped enormously in preventing and curing bedsores and in the treatment of severe burns. The gentle, even support and the warmth of a waterbed are also beneficial for people who suffer arthritis, rheumatism and certain back disorders. Furthermore, waterbeds are extensively used in the care of premature babies and are a great help for pregnant women.
Because no dust or bacteria can lodge in a sealed water mattress and because a water mattress is easy to clean, it is also frequently used in the treatment of allergies and asthma. And finally, it has been proven that one falls asleep faster and achieves a deeper sleep on a waterbed. A good uninterrupted night’s rest is generally considered one of the best medicines. The support, the comfort and the warmth all contribute to better health and a more relaxed feeling.

This is highly unlikely, unless you literally dive into bed. But that’s likely to wake your partner on a traditional mattress too. The more strongly your waterbed is stabilised the less it propagates your movements. In a well stabilised waterbed, your movements will only produce a slight and short undulation, which is usually not considered to be disturbing.

We have never heard of anyone suffering this problem. A waterbed, after all, only moves if you move, and such movement is instantly dampened by the stabilisation. You should also remember that you till toss and turn much less on a waterbed because of the reduced pressure.

We guarantee a minimum lifespan of five years. The actual life is much longer and heavily depends on how well the sleeping system is looked after. We regularly replace products which are 20 years old.
The parts that can wear out are the water mattress and the foam rails. The 4D-Comfort vinyl of our water mattresses guarantees a longer lifespan through its special composition and unique production method. Our water mattresses are also only made after you’ve placed your order. They have not been lying in storage for years.
The foam rails can easily be replaced if necessary, usually without emptying the mattress.

Actually it won’t make any difference, unless the fact that the comfortable supporting surface contributes to your sense of well-being.

No. Once all the air has been removed from the water mattress when it is installed, a waterbed makes no more noise. The very stable construction of a waterbed and the fact that the weight of water keeps it firmly in its place means that there is no more of that irritating creaking traditional bed constructions can produce.

In a soft-side waterbed this is no problem.
Waterbeds with a high stabilisation and extra pelvic support usually make getting out even a little easier.

Yes, very comfortably in fact. Your legs are automatically raised a bit because of their lighter weight. A waterbed will fully adjust to your body even when you’re sitting. So there is one mattress surface over the whole bed even if one of the partners is sitting and the other lying.

This of course depends on the size. Our water mattresses are standard 21 cm high which gives a theoretical weight of 210 kg / m². Due to the foam edges, this is in practice less. For a standard waterbed of 180x210cm, you should expect around 600 kg.

We are not aware of any case where a waterbed has sunk though a floor, or where its weight has caused damage. The weight of a waterbed causes no trouble. It is, after all, very evenly spread, so that the load is well spread out.
Modern construction standards are based on a minimum load of 150 kg/m² for the entire room. In practice, this is even more so.
A full bed weighs less per square metre than a full bookcase or refrigerator.
Buildings with full wooden floors should in principle be no problem, after all, they must meet building standards too, but when in doubt, please consult your architect.

This is highly unlikely. Our 4D comfort vinyl and our current production methods, after all, guarantee robust seams and reinforced corners. All our waterbeds are fitted with a safety liner that ensures that in the event of a leak, no water can run out of your bed.

No, unlike conventional mattresses, a water mattress does not wear with constant or extra load. The support element in a waterbed, after all, is the water itself and that keeps its properties for ever. So, your waterbed will tolerate not only very high loads but it will also maintain its comfort and spring 100% throughout its life.

Yes, but it is highly unlikely. Sharp objects that end up in your bed by accident, after all, first have to penetrate the thick cover before they can puncture your water mattress. The chances of a puncture can be almost totally ruled out if you use your waterbed normally.

Fixing a small leak in a water mattress is very easy. Because punctures usually happen on the top side of a water mattress, very little water will run out and you can repair the leak without having to empty the mattress. You can use the repair kit which is always supplied with the bed. Once a repair patch has been stuck on, the water mattress is as good as new again. A well repaired leak does not affect the life of your water mattress.

Our classic waterbeds can be fitted in most existing bed frames. The waterbed, in its entirety, with its own support, is placed in the bed frame.
You give us the exact internal dimensions of the frame and the height of the top of the sides and we produce a waterbed with perfectly fitting sizes. We adapt the height of the socle so that the upper foam edge falls just under the edge of the sides. So you can easily make the bed.

It is best to have a waterbed installed by an expert. In that way you can be sure that it has been installed correctly and that the water volume is right for you. Installation of a waterbed usually takes 1½ to 2 hours. Most of that time is taken up filling the mattress with water. Installation times will thus depend on the flow rate of the water in your home.

Once again, it is important to choose a European brand product. We demand from the manufacturer that no harmful substances are used. Mattresses made of PVC that is itself made in Europe provide the best guarantee of unquestionable quality, because they have to meet strict EU standards. The same applies to all the other materials used.

Ordinary tap water. We recommend using water that has not been treated by a water softener.

The water in a water mattress only needs to be changed if you move house. A conditioner is added at regular intervals to prevent growth of algae and bacteria in your water mattress. See  'Maintenance of a waterbed'.

Our 4-parts waterbeds can be dismantled into convenient parts that fit into an ordinary private car. It is important to follow the instructions when emptying and refilling a water mattress. Emptying a water mattress requires a powerful pump. We advise you to let the vendor do the relocation.

No. The heater in a waterbed can be set to any temperature you like. Most waterbed users prefer a temperature between 27 ºC and 30 ºC.
Because the heat comes from underneath in a waterbed, no condensation will form in the core of the mattress as happens in a traditional mattress. Fifteen minutes airing is enough to let the moisture absorbed into the cover evaporate.

Waterbeds are always heated by a specially designed heating element. Usually the water temperature is set at skin temperature, which is normally around 28 ºC. Our heating elements allow precise adjustment of the temperature, so that you can adjust it to your liking. The pleasant warmth is one of the most appreciated features of a waterbed.

A soft-side waterbed is a well-insulated system on account of its foam edges, its cover and its closed socle. Electricity consumption averages only about 1 kWh per day. The exact figure depends on the size of the bed, the temperature of the bedroom, how well-insulating your quilt is, etc.
Also look here.

No. The room temperature even in the summer is not usually sufficient to keep the water in your waterbed up to temperature. Your waterbed heating, however, will only come on very occasionally in the summer and so will use far less electricity. By setting the temperature a few degrees lower, you can make a waterbed very pleasantly cool on a hot night. A water temperature of 25 ºC should be considered the minimum.
Also look here.

Water’s natural insulating properties and high specific heat index mean that a waterbed cools down only very slowly. So, a power cut of a few hours will not cause any problems.

Good back support is very important, particularly when you are growing. That is the time when the back takes on its shape, which will be very difficult to change or correct in later years. So, a waterbed is the ideal sleeping system for a growing youngster. It has been proved that young children fall asleep more quickly, sleep for longer periods without interruption and are calmer in general if they sleep on a waterbed.

Some resellers list their prices with installation included, with others installation is extra. It’s best to discuss with your vendor what is and is not included in the price so that there are no unpleasant surprises awaiting you. Everything included, a waterbed is no more expensive that a good traditional sleeping system. A waterbed is, after all, bed, mattress support and mattress all in one.

The only drawback with a waterbed is that it is not as easy to move as a traditional bed and that it will add a few extra hours of work if you move house.
Some find the need for some maintenance is a disadvantage, but then you also get a 100% hygienic sleep system! The couple of hours this takes each year plenty make up for this.

Most insurance policies cover waterbeds in the same category as electrical equipment that uses water, like washing machines and dish washers. So there’s no need for extra insurance. For specific queries in this context, it is best to contact your insurance company.

Some resellers offer a trial period. The precise details and costs associated with such a provision vary considerably from region to region, and depend very much on the individual reseller.

This is a question that crops up more and more. Statistics show that contented water sleepers quickly convince 5 to 6 of their friends of the benefits of their sleeping system. What is striking is that many waterbed resellers started out sleeping on a waterbed and it was the benefits they experienced from it that convinced them to invest in their own business.
