A medical product must undergo various biocompatibility tests and fulfil numerous requirements. At the same time, attention must be paid to optimising care properties. Natural fibres such as cotton would absorb too much moisture, are high-maintenance, and lack antibacterial properties. For this reason, the BioRelax sleeping mat uses a specially developed synthetic fibre that is pleasantly soft, cuddly, and breathable, helping to prevent excessive sweating.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.The BioRelax Kleinsche Fields sleeping mat is supplied as a medical product in accordance with strict health protection and hygiene guidelines and comes in a protective seal.
Transport and storage
The BioRelax sleeping mat can be rolled up for transport or folded lengthways (please do not fold or crease it across its width).
Storage temperatures: –20°C to +60°C.
The BioRelax sleeping mat can also be transported on aeroplanes. It is advisable to carry it in your hand luggage for easier security checks at the airport.
Special sizes
Customised sizes are also available. Please contact us for more information.
*Can be used with 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 considered safe at a minimum distance of 1.5 cm. At this distance, the magnetic field strength is already lower than the Earth's natural magnetic field, within which all implants are permanently located. To avoid any possible negative influence on electronic implants, a minimum safety distance of 1.5 cm should be maintained between the implant 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 using permanent magnets. Over the past decades, no harmful side effects have been reported worldwide across all age groups due to static permanent magnetic fields. If in doubt, please consult your paediatrician.
10. Arguments for the BioRelax Mattress topper
- Only BioRelax Mattress toppers contain the Kleinsche Fields Technology
- Kleinsche Fields work completely without electricity or batteries.
- The Kleinsche Fields effect can be used for any length of time (all night long). The cells and metabolism are gently and naturally supported.
- Kleinsche Fields require no complicated settings or programs.
- Kleinsche Fields produce no electrosmog.
- The body needs cell regeneration for acute complaints, preventively, for athletic performance and for restful sleep.
- Owing to their effectiveness, Kleinsche Fields are medical devices. Thanks to their outstanding 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, the Class 1 medical device.
- Even after over 30 years of research, no harmful side effects whatsoever are known, and our researchers consider them impossible with such natural and gently constant fields. In contrast to electrically generated magnetic fields.
- The Mattress topper can be conveniently taken anywhere and used in any bed.
- The magnetic effect of the Kleinsche Fields does not need to be recharged.
Sleep yourself healthy
The gentle cell therapy for home
Long established: Healthy cells are the key to a healthy body. On this, modern cell medicine is in agreement. Our vitality, our immune system and our sleep quality stand or fall with cell health.
According to our findings, the cells can be trained, regenerated and made more resilient by sleeping/lying on special permanent-magnetic surfaces.
But magnet is not the same as magnet. The various therapy offerings using magnetic fields are often based on completely different technologies. One of them stands out in particular - the Kleinsche Fields Technology. It has been scientifically studied and researched for years.
What makes it special: Kleinsche Fields work completely without electricity, batteries, devices or complicated programs. Quite gently, modelled on nature and on our Earth's magnetic field. The distinctive feature lies in the pole arrangement, which, unlike conventional magnets, is very complex and particularly varied. Kleinsche Fields are found exclusively in products of the BioRelax brand.
Ready to use in 3 simple steps
Step 1

Place the Mattress topper on the mattress
Step 2

Optionally secure with a retaining strap around the mattress
Step 3

Put on the fitted sheet
Usable with or without an intermediate cover
Where should the BioRelax Mattress topper lie in the bed?
If the mattress topper is placed directly on the mattress, you can simply pull the fitted sheet over it. Alternatively, you can place an intermediate layer (e.g. a molton cover, a mattress protector, a woollen blanket or similar) over the mattress topper and then place the fitted sheet over it. Some users find an intermediate layer “cosier”. Others find that it makes care easier – if, for example, you sweat more in summer, the intermediate layer absorbs a large part of the moisture.
The intermediate layer can be machine-washed without any problem, so that the Mattress topper itself often does not need to be cleaned.
Kleinsche Fields work through all textile materials. We recommend a maximum thickness of the intermediate layer of 1 cm between the body and the Mattress topper.
Kleinsche Fields work through all textile materials. We recommend no more than 1 cm thick intermediate layers between the body and the Mattress topper.

Frequently asked questions
Can I also use the mattress topper on wider mattresses?
Yes, the mattress topper can be used on mattresses of any size. The length of the elastic bands is designed only for a mattress width of up to 100 cm, but many users do not use the elastic bands at all. For wider mattresses, we recommend placing the sleeping pad where you mainly lie in the bed (in the middle or on your preferred side of the mattress).
Can I turn the mattress topper over?
Yes, this is generally possible. However, the field strength on the back side may be somewhat lower, so we recommend permanently using the intended top side as the lying surface.
Is there a difference between the head and foot area of the mattress topper?
No, Kleinsche Fields have the same effect across the entire lying surface of the mattress topper. It therefore makes no difference whether you lie with your head at the foot end of the mattress topper or the other way around.
Can I also use the mattress topper with a grounding sheet/grounding mat?
Yes, you can also use the mattress topper with grounding sheets or grounding mats. If you use a thin grounding sheet, you can place it over the BioRelax® mattress topper. The Kleinsche Fields effect passes through and is not affected by the grounding sheet. When using a grounding mat, we recommend placing the grounding mat under the mattress topper.
Can I use electronic devices on/in the bed with the mattress topper?
Yes, you can also use electronic devices on the mattress topper or in the bedroom. Kleinsche Fields are not affected by such devices. Whether mobile phone, notebooks, lamps, electric bed frames, heating mats, etc., you can use them as you like.
General tips for a healthy sleeping place:
Please note that electrical devices connected to the power outlet usually generate electromagnetic radiation (EMF), which, according to a broad body of studies, can have negative effects on the organism. Therefore, for good health, we recommend keeping the sleeping place free of electronics, ideally at night.
Further tips and recommendations on how you can reduce your EMF exposure:
Beyond our products, as specialist experts, we would like to convey to you as much health knowledge and as many tips as possible. If you are not yet sufficiently familiar with the potentially harmful EMF, the following first 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 outlet when going to bed (or switching the outlet switch to off). As an alternative: equip the outlets with a timer that takes over the switching off automatically for you and turns the device back on at your desired time. As long as devices are not disconnected from the power grid, current usually continues to flow through them even when switched off.
- Another somewhat unorthodox way, which is usually favoured by very electrosensitive people: before going to bed, switch off the circuit breaker for the bedroom power in order to obtain a power-free bedroom.
- In the bedroom, do without devices that are connected via Wi-Fi or Bluetooth. If you do use them, they 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 putting it into airplane mode at least at night. If the mobile phone is within reach, additionally make sure not to charge it from the power grid at night, also no inductive charging. If you do not remember every evening to put the mobile phone into 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 to have the mobile phone automatically set to airplane mode at your desired time and automatically reactivated in the morning. How this pro tip works, we explain to you step by step in the following instructions.
Instructions for having airplane mode switched on and off automatically (example Apple iPhones):
1.) Open the "Shortcuts" app on your iPhone. (If not already installed: download it in the App Store. This is an in-house app from Apple and 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".
- Select "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 switching 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. 08:00 a.m. in the morning.
- 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 nevertheless still switch airplane mode on and off yourself at any time, in case you need the mobile phone at night. This autopilot makes it possible for you to have your mobile phone in the bedroom guaranteed within reach every night and mostly radiation-free.
Wi-Fi:
If you cannot do without Wi-Fi in the household but want to reduce your radiation exposure, it is advisable to purchase 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 more devices are connected to the Wi-Fi. And it switches back on by itself when a device reconnects. If you put your mobile phone into airplane mode, for example, and no other device is currently actively connected, the Wi-Fi switches off as well. This way you can also automatically "switch off" the Wi-Fi at night by itself 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 intended to be valuable for the people who do not want to do without anything and yet want to do something for their health without effort.
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 would like to use, for example, a protective blanket/woollen blanket/molton/mattress protector or similar over the mattress topper, that is no problem. Kleinsche Fields act through all textiles. Just pay attention to the thickness of all materials together, that you do not place upholstery fabrics that are too thick on the mattress topper, which would then create a distance of over 1 cm from body to mattress topper.
How do I transport the mattress topper correctly so that it does not break?
You can fold or roll up the mattress topper lengthwise as small as you like. Only folding across the width should be avoided.
What is the effect at the head when a pillow is used?
You can also 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 the shoulder to foot area lie on the mattress topper. If you would like to obtain a Kleinsche Fields effect specifically in the head area, it is advisable to place a small BioRelax mat on or in the pillowcase. Most users use the BioRelax Animal cushion with Kleinsche Fields in the size 35 x 50 cm or 45 x 60 cm for this. Some users appreciate the soft outer 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 of use that is most comfortable for you.
Can I test the mattress topper for a while?
As registered medical devices, with their intended use in bed and their materials, the BioRelax mattress toppers fall under the statutory hygiene protection provisions of the Medical Devices Act for protection against possible pathogens and germs from previous users. Because of this, passing on previously used/used/previously rented products is unfortunately prohibited for us for health protection reasons. We would be obliged to dispose of them. Therefore, after opening the hygiene protection seal of the mattress topper, we can no longer offer a return. With the hygiene protection film, however, a brief trial lying would generally be possible if the soft and flexible lying comfort is to be tested.
Guaranteed physical effect:
Every user of the Kleinsche Fields mattress topper, however, has the certainty that the physical effect occurs in every person, so that there is no person in whom Kleinsche Fields do not work. The blood, with its + and – ions, must react during movement/circulation via the constantly changing + and – poles.
Can I test something else instead?
Yes, it is different with regard to "trying something out", for example, with the BioRelax® Kleinsche Fields Pads. As an alternative, you can also unpack these and try them out. The Pads can also still be returned within 14 days after unpacking, provided they are returned in the original bag and not soiled. Should you, for any inexplicable reason, still be quite unsure with regard to Kleinsche Fields at all, you can therefore also order a BioRelax® Pad for testing in order to convince yourself of the effect. Ultimately, the same is contained in the mattress topper, only there in a very large number. A Pad cannot demonstrate the systemic and large-area effect of the mattress topper, but you can also make your first test experiences with the BioRelax® Pad.
In order to make something noticeable relatively quickly in the process, we recommend doing the foot test with the Pad.
For the foot test, you place a Pad on the floor and put one foot on it (standing or sitting does not matter). Because one foot stands on the Pad and the other does not, for a direct comparison. This way, many people can usually perceive a difference between the feet after just 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 most readily feels the small changes at this part of the body, which at other parts of the body is usually not equally subjectively perceptible for such a test due to less sensitivity.
Personal consultation regarding the mattress topper:
Should you wish for the holistic effect of the mattress topper but still be unsure, we are happy to help further in the telephone consultation. Please feel free to contact our specialist team for all your questions and concerns. With the knowledge of the health starting point from which you have certain expectations, we can, from years of practical experience and various study findings, give you an assessment of whether your expectations regarding the mattress topper are realistic, for example when it comes to certain complaints. The mattress topper can do a lot, but even with the best effect it unfortunately cannot magically make every problem disappear all on its own. Every person should pursue the goal of helping the body to help itself. In doing so, Kleinsche Fields support you in strengthening the body. The fundamental effect of the Kleinsche Fields has, as is known, already been tested and documented several times (medical device)1-6, so that with every person the only exciting question is always where one's own body can benefit from increased performance.
Is installment payment possible?
Yes, installment payments are generally possible with us. Since we know that it is not always financially easy for many people, we try to support and help as best as possible. Please feel free to 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 well-known mats/systems?
The blanket and short answer: No.
Kleinsche Fields are a special technology that is comparable neither with other magnet or frequency products, nor with electrically powered magnetic field therapies or other therapy devices.
The operation principle of the Kleinsche Fields is based on clearly different approaches than all existing devices or therapies on the market. Even if the objective of other therapies or devices may possibly seem similar in terms of cell performance, circulation (microcirculation), etc., Kleinsche Fields take a different path of the operation principle. This is mostly, on the one hand, gentler and designed with a longer and continuous duration of effect, which is why Kleinsche Fields are often described as more successful. On this website you will find further information about this in all areas of knowledge.
Can the effects be felt? And if so, from when?
In principle, the Kleinsche Fields effect is present in every person, even if some people do not feel it at all and others, by contrast, very clearly. The person and one's own nerve cells are very different in subjective perception. Even if the same thing happens in the body in people, more sensitive people notice this more clearly than less sensitive ones. Sensitive people can at the beginning rather perceive the fine micro-tension produced by Kleinsche Fields in the form of slight warmth, tingling or inner movement. Normally, however, one does not notice anything direct. Therefore, do not worry if you subjectively feel nothing while lying on the mattress topper; exactly below the perception threshold is the ultimate normal state.
Can there be an initial aggravation or signs of detoxification?
If the BioRelax Kleinsche Fields mattress topper helps the body to more cell energy, it is quite possible that in isolated cases the body then, directly in the first nights, initiates processes that it could not carry out beforehand without this performance. How you can best help your body in this phase, we explain in the following.
Explanation:
Depending on the reaction, our medical experts mostly speak of a "detoxification backlog" in this regard. Therefore, some users notice that in the first 1-4 weeks they, for example, sweat more strongly at night, perceive an inner movement/restlessness at first, or have more of a feeling of thirst during the day with going to the toilet more often.
Tips and advice from our experts:
Your body in this case works at full speed wanting to solve its inner problems. What is a first great success for professional circles can, for some users, also sometimes be unpleasant in the case of, for example, stronger detoxification reactions. If your body therefore, in your perception, 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 lengthwise in such a way that at first you only lie on it with your feet, or your legs. It does not matter whether you let part of the mattress topper hang out of the bed, lay it doubled over itself under the sheet, or lay/clamp the rest of the length around/under the mattress.
If your body then, for a few nights, lies on the mattress topper with only one part of the body, it can also work on only one part of the body. In doing so, these perceptible detoxification reactions usually reduce or disappear very well. According to your own perception, you can then, for example, every few days or every week, increase the lying surface a little in order to advance the body even without detoxification reactions and then to sleep lastingly soothingly on the mattress topper. In all these years there has not yet been any user who could not sleep permanently on the mattress topper. Therefore, even sensitive people or chronically out-treated people with severe illnesses need not worry - you too can sleep permanently on the mattress topper without any problem.
Our recommendation:
We generally recommend that all users sleep the first night completely normally on the mattress topper with the entire whole body. If everything feels nice or you notice pleasant effects, continue to sleep permanently with the entire body on it. Should your body, in case of doubt, at first produce reactions that are too unpleasant for you as described above, reduce the lying surface and afterwards increase again up to the whole body.
Good to know:
Should you be among the people who feel such initial reactions, these then disappear bit by bit over the following days and few weeks. Therefore, we more often receive questions from users after 3 months as to whether their mattress topper still works, because they no longer feel anything at all. And that although they felt so many things at the beginning. And precisely therein lies normality. Once the body has gone through this phase and over a few nights carried out its evidently necessary processes, almost all users notice, after a certain time, hardly anything to nothing at all of the mattress topper anymore - the body has excellently worked out the status for itself!
Because even if subjectively nothing more is perceived, the BioRelax® mattress topper with Kleinsche Fields continues to support your body and your cells in the generation of energy. It has already happened frequently that users who were able to establish a great improvement in health after a few weeks lent their mattress topper out within the family out of enthusiasm, and the problems came back after a short time. The nightly cell regeneration was evidently lacking in order to maintain the improved status. Therefore we definitely recommend, for sustainable health, supporting your body permanently every night with the mattress topper.
