Yes, the sleeping mat can be used on any mattress size. Although the length of the elasticated straps is only designed for a mattress width of up to 100 cm, many users do not use the elasticated straps at all. For wider mattresses, we recommend placing the sleeping mat where you primarily lie in bed (in the centre or on your preferred side of the mattress).

Care
The BioRelax Kleinsche Fields sleeping mat can be washed with soap and water or, when changing patients, cleaned with an approved surface disinfectant while observing the required exposure time.
Material
- Antiallergic.
- Breathable.
- Kleinsche Fields are incorporated over a large area.
- Handmade in Germany and manufactured according to certified medical product standards.
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 in favour of the BioRelax® sleeping mat
1. Only BioRelax sleeping mats contain Kleinsche Fields technology.
2. Kleinsche Fields work completely without electricity or batteries.
3. The effect of Kleinsche Fields can be used for as long as required (the whole night). Cells and metabolism are gently and naturally supported.
4. Kleinsche Fields do not require complicated settings or programmes.
5. Kleinsche Fields do not generate electrosmog.
6. The body needs cell regeneration for acute complaints, as a preventative measure, to support athletic performance, and for restful sleep.
7. Kleinsche Fields are registered as medical devices due to their effectiveness. Thanks to their excellent safety profile, unlike current-operated magnetic field systems, they do not fall into the higher-risk class 2, but into the lowest risk class – medical device class 1.
8. Even after more than 30 years of research, no harmful side effects have been identified. Our researchers believe it is highly unlikely with such natural and gently constant fields – in contrast to current-generated magnetic fields.
9. The sleeping mat can be taken practically anywhere and used in any bed.
10. The magnetic effect of Kleinsche Fields does not need to be charged.
Get a good night's sleep
Gentle cell therapy for at home
Long proven: healthy cells are the key to a healthy body. Modern cell medicine agrees on this. Our vitality, immune system, and the quality of our sleep all depend on the health of our cells.
According to our findings, cells can be trained, regenerated, and made more resilient by sleeping or lying on special permanent magnetic surfaces. However, not all magnets are the same. Different types of magnetic field therapy often rely on completely different technologies.
One, in particular, stands out – Kleinsche Field Technology. It has been scientifically investigated and researched for years. What makes it special: Kleinsche Fields work completely without electricity, batteries, devices, or complicated programmes.
They are modelled gently on nature and the Earth's magnetic field. The real innovation lies in the pole arrangement, which, unlike conventional magnets, is extremely complex and especially varied. Kleinsche Fields are found exclusively in BioRelax® brand products.

FAQ
Yes, in principle this is possible. However, the field strength may be somewhat lower on the reverse side, so we permanently recommend using the intended top side as a sleeping surface.
Yes, the sleeping mat can be used on any mattress size. Although the length of the elasticated straps is only designed for a mattress width of up to 100 cm, many users do not use the elasticated straps at all. For wider mattresses, we recommend placing the sleeping mat where you primarily lie in bed (in the centre or on your preferred side of the mattress).
No, Kleinsche Fields have the same effect across the entire sleeping mat surface. It therefore makes no difference whether you lie with your head at the foot end of the sleeping mat or the other way round.
Yes, you can also use the sleeping mat with earthing sheets or earthing mats. If you use a thin earthing sheet, you can place this over the BioRelax sleeping mat. The Kleinsche Fields effect passes through and is not affected by the earthing sheet. When using an earthing mat, we recommend placing the earthing mat under the sleeping mat.

Viele Menschen leiden auf Grund von mangelnder Durchblutung und Zellversorgung unter kalten Füßen, Schmerzen, Schwellungen und Missempfindungen. Weiter sollen die Einlegesohlen über die Fußreflexzonen die Nerven zum Gehirn stimulieren für eine bessere Konzentrations- und Reaktionsfähigkeit sowie die Motorik (Bewegungssteuerung). Besonders im Alter für die Sturzprophylaxe oder zur Leistungsförderung im Sport können die Einlegesohlen helfen.
