No motions are noticed
Innovative sponges put out any movement.

Let's have a look at WATER MATTRESSES - a viable alternative to over-hard or over-soft beds that are the source of a serious potential posture hazard. The possibility of regulating the water temperature also has a positive effect on conditions such as rheumatism. It has been scientifically demonstrated that sleepers turn over or move about two-thirds less on a water mattress as there are no pressure points to disturb the blood circulation. Therefore, sleeping on a waterbed is undoubtedly a step towards preventing posture defects and damage to the spine.

The sleep of your dreams... the picture shows the therapeutic value of the water mattress; the body is well supported along its whole length and even in the most delicate points, giving an exceptionally relaxing feeling, whilst always holding the body in the correct orthopedic position. It is available in several sizes (Italian, American and French ones).

Our waterbeds have been specially designed to eliminate any unwanted movement. Air bubbles may produce a slightly perceivable sound but these can be quickly and easily removed.
In no way does the presence of water cause rheumatism - the water is tightly closed within its casing and humidity is not produced. In fact, the heating system even helps prevent rheumatism
With the thermostat off, the mattress stays at room temperature (15°, 20°) giving a cool, fresh feeling. With the thermostat on the water may be heated to a maximum temperature of 38° C. When running, the mattress consumes practically no electricity (about 20 watts per hour)

As far as safety guarantees are concerned, the mattresses conform to the same rules applying to hospitals.
Should a leak occur, it should not cause alarm - the water will not spill out on to the floor as it is never under pressure and is held by the internal spongy fibers, and the whole mattress is surrounded by a water-proof shell. Any hole can be easily and quickly mended with the repair kit.
The water inside the mattress is not changed - adding a bottle of our algaecide every year is all the maintenance that is needed.

Lastly, the very reliable water-proof properties of the vinyl and the practicality of the removable, cotton, washable, pre-shrunk padded covers make these mattresses particularly hygienic, avoiding the build-up of dust and mites typical of traditional ones. This being, waterbeds are also particularly suited to allergy-sufferers. The weight load per square meter of floor is less than that of a fridge or washing machine. And prices are enticing when compared to normal orthopedic mattresses, especially when you consider that the waterbed's temperature may be regulated.

Heater is approved by main worldwide quality standard certification authority. (CE, TUV ..)  and allows, with an heating pad, to adjust water temperature.

Padded cover is removable (with a Zip).
Dry clean or machine washable (cold water only)

vinyl mattress (water mattress core) should be cleaned with a soaped wet soft cloth or sponge, using, if possible, proper detergent (vinyl cleaner).
Absolute vinyl impermeability avoid any dust or acarus "nesting", classic problem in traditional mattresses. Therefore watermattress is absolutely the more hygienic and is advisable for anyone is allergy sufferer.
