- Care
- The BioRelax Kleinsche Fields sleeping mat can be washed with soap and water or cleaned with an approved surface disinfectant when changing patients, observing the required exposure time.
- Material
- A medical device must undergo various biocompatibility tests and fulfil a large number of requirements. At the same time, care properties must be optimised. Natural fibres such as cotton would absorb too much moisture, are high-maintenance, and are not antibacterial. For this reason, the BioRelax sleeping mat uses a specially developed synthetic fibre that is pleasantly soft and cuddly, and minimises perspiration. All materials – from the outer fabric to the Kleinsche Fields, yarn, inner fleece, elasticated straps, and labels – are produced in accordance with the highest quality standards and EU regulations. For a medical product that is as free from harmful substances as you could wish for.
- Medical device and hygienic health protection
- The BioRelax Kleinsche Fields sleeping mat is supplied as a medical device in accordance with health protection and hygiene guidelines, delivered in a protective seal.
- Transport and storage conditions
- The BioRelax sleeping mat can be rolled up for transport or folded lengthways (please do not fold or crease widthways).
- Special sizes
- Customised sizes are also available. Please contact us for more information.
* Can be used for all metal, ceramic, or zirconium oxide implants in the body that do not have ferromagnetic properties. If the composition of the implant is unclear, application is safe at a minimum distance of 1.5 cm. At this distance, the magnetic field strength is already below the Earth's natural magnetic field strength, within which each implant is naturally and permanently located. To exclude any possible negative influence on electronic implants, a safety distance of at least 1.5 cm should be maintained between electronic implants and the product.
** BioRelax products with Kleinsche Fields are intended for use by children aged 10 years and older, and adults, without height or weight restrictions, within the home environment. There are no known negative findings regarding the risks for children under 10 years of age with permanent magnets. If in doubt, please consult your paediatrician. Over recent decades, no harmful side effects have been reported worldwide across all age groups due to the use of permanent static magnetic fields.
10 arguments in favor of the BioRelax mattress topper
- 1. The Kleinsche Fields technology is found only in BioRelax mattress toppers
- 2. Kleinsche Fields work entirely without electricity or batteries.
- 3. The Kleinsche Fields effect can be used for as long as desired (the entire night). The cells and metabolism are supported gently and naturally.
- 4. Kleinsche Fields require no complicated settings or programmes.
- 5. Kleinsche Fields produce no electrosmog.
- 6. The body needs cell regeneration in cases of acute symptoms, preventively, for athletic performance and for restful sleep.
- 7. Due to their effectiveness, Kleinsche Fields are medical devices. Thanks to their excellent safety profile, unlike electrically-powered magnetic field systems, they do not belong to the higher risk and hazard class 2, but to the lowest risk class, medical device class 1.
- 8. Even after more than 30 years of research, no harmful side effects are known, and our researchers consider them impossible with such natural and gently constant fields. In contrast to electrically generated magnetic fields.
- 9. The mattress topper is very practical to take anywhere and can be used on any bed.
- 10. The magnetic effect of the Kleinsche Fields does not need to be charged.
Sleep your way to health
Sleep your way to health
Gentle cell therapy for home
Long established: healthy cells are the key to a healthy body. Modern cell medicine is in agreement on this point. Our vitality, our immune system and the quality of our sleep stand or fall with cell health.
According to our findings, cells can be trained, regenerated and made more resilient by sleeping or lying on special permanent-magnetic surfaces.
But not all magnets are equal. The various magnetic field therapy options are often based on completely different technologies. One of them stands out in particular - Kleinsche Fields technology. It has been scientifically studied and researched for years.
What makes it special: Kleinsche Fields work entirely without electricity, batteries, devices or complicated programmes. Very gently, modelled on nature, or rather our Earth's magnetic field. The particularity lies in the pole arrangement, which, unlike conventional magnets, is very complex and especially varied. Kleinsche Fields are found exclusively in BioRelax brand products.
Ready to use in 3 simple steps
Usable with or without an intermediate cover
Step 1

Place the mattress topper on the mattress
Step 2

Optionally secure with a strap around the mattress
Step 3

Put on a fitted sheet
Usable with or without an intermediate cover
Where should the BioRelax mattress topper lie in the bed?
Once the mattress topper is on the mattress, you can place the fitted sheet directly over it. Likewise, if you wish, you can place an intermediate cover (e.g. Molton, mattress protector, woollen blanket or similar) on top of the mattress topper and only then place the fitted sheet over it. Some users find an intermediate layer even "cosier". For others, an intermediate layer makes care easier. If you sweat more, for example in summer, this is then mainly caught by the intermediate layer. This in turn can simply be washed in the washing machine. This way, many users do not need to clean the mattress topper additionally. Kleinsche Fields work through all textile materials. We recommend no more than 1 cm of intermediate layers between the body and the mattress topper.

Questions & Answers
Can I also use the mattress topper on wider mattresses?
Yes, the mattress topper can be used on any mattress size. The retaining elastic bands are only designed for a mattress width of up to 100 cm, but many users do not use the retaining bands at all. For wider mattresses, we recommend placing the mattress topper in the spot of the bed where you mainly sleep (in the middle or on your preferred side of the mattress).
Can I also turn the mattress topper over from time to time?
Yes, in principle this is possible. The field strength can, however, be somewhat lower on the reverse side, so we recommend permanently using the intended top side as the lying surface.
Does BioRelax also manufacture mattress toppers in other sizes?
Yes, in our own sewing workshop in Bremen (Germany) we can realise almost any custom size by hand on customer request. This size can be manufactured for you with a surcharge. If you are interested in another size, please contact us.
Is there a difference between the head and foot area of the mattress topper?
No, Kleinsche Fields are uniformly the same in their effect across the entire mattress topper surface. It therefore makes no difference whether you lie with your head at the foot of the mattress topper or the other way round.
Can I also use the mattress topper with an earthing sheet or earthing mat?
Yes, you can also use the mattress topper with earthing sheets or earthing mats. If you use a thin earthing sheet, you can place this over the BioRelax mattress topper. The Kleinsche Fields effect passes through and is not influenced by the earthing sheet. When using an earthing mat, we recommend placing the earthing mat under the mattress topper.
Can I use electronic devices on or in bed with the mattress topper?
Yes, you can also use electronic devices on the mattress topper or in the bedroom. Kleinsche Fields are not influenced by such devices. Whether mobile phone, notebooks, lamps, electric bed frames, heating mats, etc., you can use them as you wish.
General tips for a healthy sleeping place:
Please note that electrical devices connected to the mains usually generate electromagnetic radiation (EMF), which, according to a broad body of studies, can have negative effects on the organism. We therefore recommend, for good health, to keep the sleeping place as electronics-free as possible at night.
Further tips and recommendations on how to reduce your EMF exposure:
Beyond our products, we would like to share with you, as specialist experts, as much health knowledge and tips as possible. If you have not yet sufficiently familiarised yourself with potentially harmful EMF, the following initial small practical tips could help you to reduce your radiation exposure quite easily for better health:
- If you cannot do without electrical devices in the bedroom, we recommend unplugging the devices from the socket when going to bed (or switching the socket switch off). As an alternative: fit the sockets with a time switch that automatically takes care of switching off for you, and switches the device back on at your desired time. As long as devices are not disconnected from the mains, electricity usually continues to flow through them even when switched off.
- Another somewhat unorthodox path, which is mostly preferred by very electro-sensitive persons: before going to bed, switch off the circuit breaker for the bedroom power, to obtain an electricity-free bedroom.
- Do without devices in the bedroom that are connected via Wi-Fi or Bluetooth. If you do use them, these should only be active when a connection is needed. Which at night is usually not the case.
- If you cannot do without your mobile phone in the bedroom, we recommend at least setting it to airplane mode at night. If the mobile is within reach, also make sure not to charge it on the mains at night, also no inductive charging. If you do not remember every evening to put the mobile phone in airplane mode, you can also do it like BioRelax KleinMed managing director Marco Klein, who shares this tip with you: if needed, activate the automatic settings so that the mobile phone is automatically put into airplane mode at your desired time, and reactivated automatically in the morning. How this professional tip works, we explain to you step by step in the following instructions.
Instructions for automatically switching airplane mode on and off (example Apple iPhones):
1.) Open the "Shortcuts" app on your iPhone. (If not already installed: download it from the App Store. This is an in-house app from Apple and is safe.)
2.) Tap on "Automation" at the bottom.
3.) Tap on "+" (top right) and select "Create personal automation"
- Select "Time of day" as the trigger.
- Set the desired time at which airplane mode should be activated. Example: 11:30 p.m. for the night.
- Then tap on "Next".
- Then tap on "Add action".
- Enter "airplane mode" in the search bar and select "Set Airplane Mode".
- Choose "Turn On".
- Tap on "Next" and deactivate "Ask before running", so that the automation runs automatically.
- Tap on "Done" to save the first automation.
4.) Create a second automation for deactivating airplane mode:
- Now repeat the process for turning off airplane mode.
- Tap again on "+" → "Create personal automation".
- Select "Time of day" as the trigger. Set the time for deactivating airplane mode, e.g. mornings 8:00 a.m.
- Tap on "Add action", search for "Set Airplane Mode", and set it to "Turn Off". - Tap on "Next" and deactivate "Ask before running" and save with "Done".
You can still always switch airplane mode on and off yourself, if you do need the phone at night. This autopilot makes it possible to have your mobile phone in the bedroom every night, guaranteed to be ready to hand and predominantly radiation-free.
Wi-Fi:
If you cannot do without Wi-Fi in your household, but want to reduce your radiation exposure, it is advisable to acquire a low-radiation router. The company JRS Eco, for example, has routers that reduce up to 90% of the radio radiation. In Eco mode, the Wi-Fi even switches off by itself when no devices are connected to it anymore. And it switches itself back on as soon as a device reconnects. If you set your mobile phone, for example, to airplane mode and no other device is currently actively connected, the Wi-Fi also switches off. In this way you can also automatically have the Wi-Fi "switch off" by itself at night, without having to disconnect the router completely from the power.
Of course, there are many more possibilities and other ways to reduce your radiation exposure. In our experience, people often do not want to change much in their lives, so these tips are already meant to be valuable for those who do not want to give anything up and yet still want, without effort, to do something for their health.
Up to what distance from the mat is the effect present?
We recommend having no more than 1 cm (10 mm) of distance or intermediate layers between the body and the mattress topper, so that enough of the field reaches the body. If you wish to use a protective cover/woollen blanket/Molton/mattress protector or similar above the mattress topper, this is no problem. Kleinsche Fields work through all textiles. Just make sure that the combined thickness of all materials does not create a distance of more than 1 cm between the body and the mattress topper, by avoiding overly thick padding materials on top of the mattress topper.
How do I transport the mattress topper correctly so that it does not get damaged?
You can fold or roll up the mattress topper lengthwise as small as you like. Only folding it across its width should be avoided.
What is the effect on the head when a pillow is used?
You can sleep with a pillow without any problem. For the general effect of Kleinsche Fields it is not necessary for the head to lie directly on the mattress topper. It is sufficient if shoulders to feet rest on the mattress topper. If you specifically want a Kleinsche Fields effect in the head area, we recommend placing a small BioRelax mat on or in the pillowcase. Most users use the BioRelax animal cushion with Kleinsche Fields for this purpose, in size 35 x 50 cm or 45 x 60 cm. Some users appreciate the soft top fabric of the animal cushion, others take the Kleinsche Fields inlay out of the fur cover and slide it into the pillow. You can use the variant which is most pleasant for you.
Can I test the mattress topper for a while?
The BioRelax mattress toppers, as registered medical devices, fall under the statutory hygiene protection regulations of the Medical Devices Act, due to their intended use in bed and the materials involved, to protect against possible pathogens and germs from previous users. Due to this, the resale of previously used/used/previously rented products is unfortunately prohibited for us on health protection grounds. We would be required to dispose of them. Therefore, once the hygiene protection seal of the mattress topper has been opened, we can no longer offer returns. With the hygiene protection film, however, a brief test-lie would in principle be possible, if you wish to test the soft and flexible lying comfort.
Guaranteed physical effect:
Every user of the BioRelax mattress topper has the assurance that the physical effect occurs with every person, so that there is no person on whom Kleinsche Fields do not work. The blood with its + and - ions has to react, during movement/circulation, to the constantly alternating + and - poles.
Can I test something else instead?
Yes, when it comes to "trying something out", this is, for example, the case with the BioRelax Kleinsche Fields pads. These you can alternatively also unpack and try out. The pads can still be returned within 14 days even after unpacking, provided they are returned in the original bag and not soiled. If, for any unclear reason, you are still very unsure about Kleinsche Fields, you can therefore also order a BioRelax pad as a test, to convince yourself of the effect. Ultimately, the same is in the mattress topper, only there in very large quantity. While a pad cannot demonstrate the systemic and large-area effect of the mattress topper, you can also have your first test experiences with the BioRelax pad.
To make something relatively quickly noticeable, we recommend doing the foot test with the pad.
For the foot test, place a pad on the floor and put one foot on it (whether standing or sitting doesn't matter). Because one foot stands on the pad and the other does not, for a direct comparison. Many people can usually already perceive a difference between the feet after 1-10 minutes (e.g. more warmth, tingling or similar). That is what you want to experience in this test, in order to understand. Due to the many nerves in the sole of the foot, one usually feels small changes there earliest, which at other parts of the body, due to lower sensitivity, are usually not equally subjectively perceptible for such a test.
Personal advice on the mattress topper:
If you would like the holistic effect of the mattress topper, but are still unsure, we are happy to help further in a telephone consultation. Please contact our specialist team for all your questions and concerns. With the knowledge of your initial health situation and certain expectations, we can give you, based on years of practical experience and various study insights, an assessment of whether your expectations of the mattress topper are realistic, for example regarding specific complaints. The mattress topper can do a lot, but even with the best effect it cannot, unfortunately, magic every problem away on its own. Every person should pursue the goal of helping the body to help itself. Here, Kleinsche Fields support the body to strengthen itself. The fundamental effect of the Kleinsche Fields is known to have been tested and documented multiple times (medical device)¹⁻⁶, so the only exciting question for each person is where one's own body can benefit from increased performance.
Are instalment payments possible?
Yes, instalment payments are generally possible with us. Since we know that financially it is not always easy for many people, we try to support and help as best as we can. Please contact us about this and our service team will support you in finding a suitable solution together.
Is the BioRelax mattress topper the same as other known mats/systems?
The blanket and short answer: No.
Kleinsche Fields are a special technology, which is comparable neither with other magnetic or frequency products, nor with electrically-powered magnetic field therapies or other therapy devices.
The principle of action of the Kleinsche Fields is based on noticeably different approaches from any existing devices or therapies on the market. Even if the objectives of other therapies or devices may appear similar - possibly cell performance, blood circulation (microcirculation), etc. - Kleinsche Fields go a different route in their principle of action. This is usually on the one hand gentler and designed for longer and more continuous duration of effect, which is why Kleinsche Fields are often described as more successful. You will find further information on this on this website across all knowledge areas.
Can the effects be felt? And if so, from when?
Fundamentally, the Kleinsche Fields effect is present in every person, even if some people do not feel it at all and others very clearly. People and their own nerve cells differ greatly in subjective perception. Even when the same thing happens in the body across people, more sensitive people notice this more clearly than less sensitive ones. Sensitive people can, in the beginning, perceive the fine micro-tension generated by Kleinsche Fields in the form of slight warmth, tingling or inner movement. In normal cases, however, one does not notice anything directly. Therefore, do not worry if you subjectively feel nothing while lying on the mattress topper - the ultimate normal state is precisely just below the threshold of perception.
Can there be an initial worsening or signs of detoxification?
If the BioRelax Kleinsche Fields mattress topper helps the body to gain more cell energy, it is quite possible that, occasionally, the body initiates processes directly in the first nights that it had previously been unable to carry out without this added performance. How you can best help your body in this phase, we explain in the following.
Explanation:
Our medical experts, depending on the reaction, mostly speak of "detox backlog". Therefore, some users notice that in the first 1-4 weeks they, for example, sweat more strongly at night, perceive an inner movement/unrest at the beginning, or have more thirst during the day with more frequent visits to the toilet.
Tips and advice from our experts:
Your body is in this case working at full speed to want to solve its inner problems. What for professional circles is a great first success can, in the case of stronger detox reactions for example, also sometimes be uncomfortable for some users. If your body therefore, by your sense, wants to regenerate too much at once and you therefore find it hard to come to rest, you can, as a tip, reduce the lying surface for the first nights.
You can then either place the mattress topper crosswise in the bed, or lengthways such that you initially lie on it only with your feet or your legs. It does not matter whether you let the mattress topper hang partly out of the bed, fold it double on top of itself under the sheet, or place/tuck the remaining length around/under the mattress.
If your body then for a few nights lies only with part of the body on the mattress topper, it can also only process part of the body. By doing so, these perceptible detox reactions usually reduce or disappear very well. According to your own feeling, you can then for example every few days or each week increase the lying surface a little, in order to also progress the body without detox reactions, and to then sleep beneficially on the mattress topper permanently. In all these years there has been no user who could not sleep on the mattress topper permanently. Therefore, even sensitive persons or chronically over-therapied people with severe illnesses do not need to worry - you too can sleep on the mattress topper permanently without any problems.
Our recommendation:
We generally recommend to all users to sleep on the mattress topper completely normally the first night with the entire body. If everything feels nice or you notice pleasant effects, continue sleeping on it permanently with the entire body. Should your body in case of doubt initially produce reactions that are too uncomfortable for you, as described above, reduce the lying surface and then increase it again up to full body.
Good to know:
Should you belong to the people who experience such first reactions, these will disappear bit by bit over the following days and few weeks. We therefore receive from users sometimes after 3 months questions on whether their mattress topper still works, because they feel nothing at all anymore. And this although they felt so many things at the beginning. And exactly that is the normality. Once the body has gone through this phase and carried out its obviously necessary processes over a few nights, almost all users notice after a certain time hardly anything or nothing at all from the mattress topper - the body has built up its status excellently!
Because even if subjectively nothing more is perceived, the BioRelax mattress topper with Kleinsche Fields continues to support your body and your cells in their energy generation. It has often happened that users, after noticing a great improvement in health after a few weeks, lent out their mattress topper to family members in their enthusiasm, and the problems came back after a short time. The nightly cell regeneration was obviously missing, to maintain the improved status. We therefore definitely recommend for sustainable health to permanently support your body with the mattress topper every night.
