Construction of a Water Bed Part 2

Another method is the use of foam cylinders, which not only provides a strong calming effect, but also simplifies entry and exit.

Some manufacturers also provide wave damping by dividing their water mattresses into chambers.

Water beds are offered in different calming levels, which are designated with the letter F and a number. The bandwidth ranges from F0 for a completely calm bed (water moves for approx. Seven to ten seconds) to F10 for a very strongly or completely calm bed without water movement.

When it comes to calming the waterbed, the type of stabilization is of secondary importance. The main thing is that the selected calming level offers the user the desired feeling of lying down.

What is Lumbar on a waterbed?

The term lumbar is used to identify the lumbar vertebrae. The lumbar spine is also described as the pars lumbalis, for example. In the area of ​​water beds, lumbar or lumbar support or lumbar support means a specially designed storage zone in the water mattress that serves to support the pelvis. One speaks sometimes of a lumbar support or lumbar support (short: LS).

The lumbar support is integrated in the waterbed as part of the calming. The storage area for the hips / buttocks or the pelvis is then calmed down more, for example by an additional intermediate layer between the fleece mats – that is, a little firmer or more buoyant in order to achieve better support and prevent sinking too deeply. With some manufacturers it is standard from a certain calming level, with other manufacturers it can be selected as an additional option on request.

In the case of a water mattress with lumbar support, this can usually not be felt subjectively. The choice of a waterbed with lumbar support is particularly recommended for people who suffer from intervertebral disc problems and for people with a higher body weight. Belly sleepers usually benefit from lumbar support, as this balances out the heavy stomach area and lighter legs and thus prevents the body from getting into an “unhealthy” hollow back or the spine from being brought out of its natural shape.

Cover / top plate

So that the moisture released by the body during sleep can be absorbed by the sleeping pad and for a more comfortable lying feeling, the water mattress of the bed is provided with a cover, which is also known as the top plate. This top plate also has a protective function for the vinyl water mattress.

The top plate of the waterbed is made from materials that have already proven themselves in the manufacture of conventional mattress covers. Analogous to the large range of mattress covers available, there is also a large variety of models for the top plates for waterbeds, which are characterized by different functionalities and properties. This also includes covers made from pure cotton, from various blended fabrics or from pure synthetic fibers, as well as from natural fibers such as virgin sheep’s wool.

Each material or each material combination offers advantages and disadvantages, so that in the end it is personal preferences and individual requirements that should point the way when deciding on the top plate of the waterbed. Covers made from modern synthetic fibers, for example, are often easier to care for than covers made from 100% cotton. In addition, unlike cotton, synthetic fibers are “unpopular” with house dust mites, which is particularly beneficial for allergy sufferers.

As with conventional mattress covers, the top panels of waterbeds are often given a textile finish. The use of special processes gives the covers additional properties such as an antibacterial and antiviral effect through the use of aloe vera. We present some common processes for textile finishing as well as common types of mattress coverings in a separate article in sleep magazine: Different mattress covers – how does the cover affect the quality of sleep?

Regardless of which material is preferred when choosing the top plate for the waterbed, it should be ensured that it is washable or can be cleaned. When it comes to purchasing a double waterbed from 160 cm width, it is advisable to choose a cover split in the middle to ensure that the cover fits into a normal household washing machine. If you decide on a continuous cover or a continuous top plate in the double bed format, you have to take it to a suitable laundry or dry cleaner every three months, which is associated with additional work and costs. With a divisible top plate, the cover consists of two parts that can be connected with a zipper. The zipper is incorporated

So that the water mattress can “work” without restriction, the cover should be made as elastic as possible. The more flexible the top plate, the better the vinyl on the mattress can adapt to the body.
