The Best Water Pillow: Our Picks

Guide: Questions you should ask yourself before buying a water pillow

What exactly is a water pillow?

A water pillow is a pillow that is filled with water. More precisely, a water pillow has a water tank at its core. This has a valve through which you can fill and drain water.

The water tank can hold two to five litres of water, depending on the size of the pillow and the desired degree of hardness. (Image source: pixabay.com / PublicDomainPictures)

Around the tank is an insulating layer that regulates the temperature of the filled water and is also waterproof. Above this is the padding, which is often made of cotton or synthetic fluff. Finally, there is usually a protective cover that encloses the cushion. A pillowcase is then pulled over this cover layer as usual. You can buy water pillows empty, i.e. without water, and fill them yourself at home. Depending on the desired degree of hardness, water is filled in using the funnel provided. How to fill your water pillow correctly is described in more detail in the "Trivia" section below.

The padding makes a water pillow feel like a normal pillow at first.

Who is a water pillow suitable for?

In principle, water pillows are suitable for everyone. However, the many benefits make the water pillow one of the most popular pillows especially for people with cervical spine problems. Due to the individual adjustment, based on the amount of water filled in, a water pillow can have a very positive effect on the neck area. Another advantage, which at first appears to be a disadvantage, is the weight of the water pillow. However, because of the water it contains, a water pillow is much heavier than a conventional pillow. We consider this a positive feature because, in comparison to a down pillow, the filling cannot shift during frequent movements during sleep.

On the other hand, a water pillow requires continuous maintenance. You should not disregard this - if you want to enjoy your water pillow for a long time, you have to expect regular care.

What are the advantages and disadvantages of a water pillow?

At first glance, the advantages seem to outweigh the disadvantages. Even on closer inspection, this does not change. This is no exaggeration - water pillows can be life-changing for many people. Because of the pillow's infinite height adjustability, it can be customised to suit anyone's needs. Depending on the desired height, two to five litres of water are filled in.

Advantages
  • Infinitely height-adjustable
  • Perfect and lasting support
  • Stable yet very soft
Disadvantages
  • More maintenance-intensive than conventional pillows
  • Can cause problems if it leaks or is not closed well

Compared to conventional pillows, a water pillow offers permanent support. This means that the head does not sink in and thus overstretching of the cervical spine is prevented. This results from the fact that the filling of simple pillows is flattened over time.

What are the alternatives to a water pillow?

Even though water pillows are often the best choice for neck tension and such problems, there are still good alternatives.

Alternative Material
Neck pillow Latex, viscose, spelt, millet
Gel pillow Hi-Tech gel foam (memory foam)

Thanks to innovative technologies, there is a wide range of pillows that offer both comfortable sleeping and perfect support. Especially gel pillows in ergonomic shape and made of point-elastic materials like memory foam, offer the best alternative to high-quality water pillows. These gel pillows can be completely filled with gel or they have a gel component. They are intelligently created and specifically designed to relieve neck problems and pain.

Which mattress goes with a water pillow?

It should be noted in advance that a mattress, like a pillow, must support the spine in such a way that it retains its natural shape in any sleeping position. Lying "crookedly" on a mattress that does not fit will support the spine poorly or not at all, which promotes muscle tension. In addition to a suitable ergonomic pillow, you also need a mattress that fits your needs. However, finding one is usually easier said than done. There are a few factors to consider here:

  • Body weight
  • Body height
  • Age
  • preferred sleeping position
  • Allergies

People spend almost a third of their lives in bed, so you should place a lot of value on high quality pillows, mattresses, slatted frames and beds. The huge selection on the market today does not make your decision any easier. In the end, only the optimal combination of pillow, mattress and slatted frame leads to a really good night's sleep. The mattress should fit like a glove and keep your body in balance. It is good to try out a mattress in a store to make a rough selection. However, you will not be able to make a final judgement with a 5-minute test lie. That's why manufacturers of high-quality mattresses offer a test lying period of several weeks and if you don't like the mattress, you can exchange or return it free of charge. As you can see, the above question about the right mattress is not easy to answer. According to our research, mattresses with a higher degree of firmness are better suited for people with muscle and spinal problems. Therefore, the editors' tip here would be to bed down on a mattress that is as hard as possible in combination with a water pillow.

Buying criteria: Use these factors to compare and evaluate water pillows

In the following section, we will show you which aspects you can use to decide between the many possible water pillows. The criteria you can use to choose the right water pillow for you are:

  • Material
  • Brand
  • Size

In the following paragraphs, we will explain to you what is important in the individual criteria.

Material

Water pillows, like conventional pillows, can be made of different materials. In the case of water pillows, however, this only applies to the upper materials, as the pillow core of all water pillows is made of tear-resistant plastic. The padding, which forms the layer between the tank and the cover, can be made of the following materials:

natural materials synthetic materials
cotton polyester
down viscose

It should be noted here that natural materials are better at regulating moisture and are therefore preferable for people who sweat a lot. The final layer is usually a cotton cover. Microfibre covers are no longer uncommon. Here, too, it should be noted that natural materials are more breathable. They also absorb moisture more effectively and release it continuously into the environment.

Brand

Due to the relative newness of water pillows in German-speaking countries, the market and the brands on offer are easy to keep track of. The top seller in most online shops is the 5001 water pillow from the company Mediflow. Health-Effect and Sleepling are also very strongly represented in Germany. It's hard to say which brand is right for you. Qualitatively, there is no difference between the top 3 companies mentioned. Like so many things, this is also a matter of taste.

Size

For water pillows, two sizes seem to have proven themselves. In any case, the following sizes are provided by all suppliers:

  • 40 x 80 cm
  • 50 x 70 cm

It should be noted here that the size has no effect on the health benefits of a water pillow. Which size is right for you depends solely on how much space you have available in your bed and what size your existing pillowcases are.

Facts worth knowing about water pillows

How do you fill a water pillow correctly?

Many manufacturers of water pillows come with a practical filling aid. This is a funnel that is adapted to the size of the filling opening. This prevents water from getting onto the inner layers of the cotton or synthetic layer during filling. If this does happen, it is recommended to place the pillow in the sun for a few hours so that the filling material can dry out completely. Otherwise mould may form. The following video describes how to fill your water pillow with water. Make sure that the remaining air is expelled - more information on this in the video:

My water pillow gurgles, is that normal?

No, it shouldn't be. If your water cushion gurgles, this is a sign that you did not let out the air when filling it. The best thing to do is to go back a step to the topic "How to fill a water pillow properly". If you follow the instructions, your water pillow should no longer make any noise.

The water cushion is leaking, what can I do?

If your water cushion leaks at the cap, first check that the cap is screwed tight. If this is the case, then deposits of calciferous water may be a reason for leaking water. In this case, careful cleaning of the thread with a diluted vinegar solution can remedy the situation.

To prevent this in the future, it can be useful to fill your water cushion with distilled water.

Many manufacturers also recommend the use of so-called conditioner tablets - more on this below.

How do you clean a water pillow?

You cannot wash your water pillow as a whole in the washing machine. Only the cover can be changed regularly and, depending on the manufacturer's instructions, washed in the washing machine. The pillow core, i.e. the water tank, requires separate treatment. More about this in the next section.

The water in my water pillow stinks. How can I prevent this?

Water that is not in motion, like in a river, can break sooner or later. This means that algae form from bacteria, which can smell unpleasant. Therefore, it is important to keep the water germ-free. The principle is the same as for waterbeds. Special conditioning tablets and liquids are suitable for this purpose. These are usually offered by the manufacturers together with the water pillows. For water pillows, the use of conditioner liquids is preferable. These are easier to dose to the comparatively small amount of water in a water cushion.
