The technology of our waterbeds

The basic principles of a water mattress

The supporting or carrying element of a water mattress is simply WATER. Floating on water, such as a ship, operates according to the principle of Archimedes. As humans, we can float in water according to the same principle (at least if our lungs are full of air). If you float, you will be as it were weightless. That's why we use the term "floating sleep".
In a pool you float almost completely below the surface because the human body is slightly heavier than water, The water can completely surround your body. By separating your body from the water with a PVC wall and because the PVC wall and the cover deform less easily than just water, you will float 'higher' on the water (and of course: without getting wet :-)) . In case of a floating object, the counter-pressure of the water is equally devided everywhere. So you are perfectly supported, what makes a waterbed the optimal sleep system.

Floating sleep

Water is highly mobile. That's why the movement is damped with a stabilising system. We use fiber mats and/or foam for this. This way we can offer a broad range of stabilisations, from nothing to very firm.
People who are somewhat heavier around the pelvic area have a tendency to sink deeper into the mattress in that area. For this we offer an optional pelvic support.

As a manufacturer, we can establish that our customers can be divided in two groups: the first group are the supporters of the 'classical' sleeping on water, who even enjoy a little movement. The second group are the sleepers who prefer the feeling of a dry mattress combined with the benefits of a water mattress, and thus choose a stronger stabilisation. Both are possible with our products.
We definitely recommend going to a merchant's showroom and test different stabilisations to feel what you like best.
Please note that every mattress, dry or water, takes some 'getting used to'. Many people sleep as a rose on the first night, others need a few days. After that, most waterbed sleepers never want to miss their waterbed again!

We also want to give a little warning if you compare water mattresses: the stabilisations and their characterisation are not absolute, each manufacturer has its own structure and names for the stabilisation. 100% or 'strong' from manufacturer A is not necessarily the same as 100%, or "strong" from manufacturer B.

A waterbed needs to be heated, even during the summer, how contradictory this may sound.
With the thermostat you can set a temperature between 24 and 36°C. The temperature setting you choose depends on the individual, the temperature in the bedroom and the insulation grade of the linen. The default is 28°C, which corresponds to the outside temperature of our skin.
In winter, you can go a little higher, eg. up to 30°C. The bed then feels comfortably warm. Never step in a cold bed again!
In summer you can drop to 25 and 26°C, making the bed pleasantly cool to the touch. Hence our slogan "Waterbeds are cool, waterbeds are hot." Never go lower, because the muscles cool down too much and you can get up with a stiff feeling.

We supply a DUAL-waterbed with two heaters so you can set the temperature right and left separately.

By default we deliver ceramic heaters with an output of 240W.
This heater is waterproof, has an overheating protection and features TÜV and GS certificates.
The energy consumption of the heater depends on the temperature setting, the temperature in the bedroom and the insulation grade of the linen. You may count with an average of 1 kWh per day. In winter, this will be some more. During hot summer days, the heater will rarely switch on. This energy consumption is a low cost for a lot of comfort.
Most of our waterbeds are provided with an insulating layer between the bottom and the heating element, so that downward heat loss is reduced. Together with the foam edges, the cover and your bedlinen the heat is 'kept in' as much as possible.
'Energy-efficient' electric heating is a myth. Electric heating always has an efficiency of 100%. Only the insulation matters.
The small amount of heat that escapes despite that, is not lost. It is indirectly contributing to the heating of the bedroom.

The parts of a waterbed
As an example, this image shows the cross section of a Armada waterbed with DUAL mattresses, Combifix-cover and a standard socle.
1 Cover

The cover encloses and protects the water mattress. It absorbs any perspiration during the night and spreads and vaporises it during the day.

2 Mid-zip of the cover

This option makes it possible to wash the cover in two parts in an ordinary washing machine.

3 Water mattress

The most important part of the waterbed. Detailed Info here.

4 Stabilisation

The stabilisation system in the water mattress for more or less movement of the water.

5 Insulation divider

The insulation divider in case of a DUAL-mattress protects the sides of the mattress and helps to maintain different temperatures left and right if set.

6 Safety liner

The safety liner captures the water in the unlikely case of a leak. We provide reinforced preformed liners of our own make that are sewn ànd welded.

7 Heater(s)

The heating element is placed between the insulation pad and the safety liner and positioned at the foot end.

8 Thermostat

The thermostat can be placed as desired, in the vicinity of the bed, out of sight or not. (You normally need to adjust it only a few times a year.) In the above illustration, an optional cable entry is used.

9 Foam rails

These form the 'tub' or 'mattress support' in which the water mattress lies. They consist of a foam with high density and resistance to deformation. They are coated with a reinforced cloth.
The whole forms a soft edge, hence the term 'soft-side', which makes getting in and out enjoyable. (Earlier so called hard-side waterbeds had a hard wooden edge.)

10 Soft-side

The 'Soft-side' consists of plastic profiles or rigid foam rails which, together with the bottom plate and the upper foam rails, form the 'base' or 'bedstead' of the bed.
All our classic waterbeds have hinged foam rails allowing the cover to move freely with the body. Also, as a result, the bed is easy to make and all standard fitted sheets will fit.
The lower visible part of the soft-side is upholstered with a fabric or imitation leather of your choice.
Since there are two parts (rigid profiles at the bottom and soft foam rails at the top) in the terminology this is called a 'Split Soft-Side'.
Our bottom plates are made in four parts making it possible to move the bed through narrow passages and stairs.

11 Plinth boards

Together with the cross-supports (no.12) this forms the 'socle' on which the bed rests.
The plinth boards are finished with melamine or upholstered with a fabric or imitation leather of your choice.
The space under the bed can be made useful with optional drawers and/or a safe.

12 Cross supports

Distribute the weight evenly across the floor.

13 Insulation pad

Limits downward heat loss.
