The BioRelax mattress topper
Sleep naturally.
Intelligently supported.
When technology follows nature, sleep can be simple again
Good sleep needs more than time. It needs conditions that allow the body to regenerate again at night.
Today, sleep has become an optimisation project. From new routines to supplements to tracking apps – many things are meant to help improve regeneration. But genuine, natural sleep does not come from ever more measures, but from the right foundation.
Our insight: what matters is not more complexity, but simple changes – and technological solutions that work in harmony with nature and support the body's own regeneration.
It was precisely from this understanding that the BioRelax mattress topper was created: it combines ancient laws of nature with innovative technology – with one clear goal: to make the bedroom a place of genuine recovery once again.
Sleeping well? No longer a given today!
Light, noise and technology rob us of sleep ever more often.
We know that the bedroom should be a place of recovery. A place where the body can let go, the nervous system can settle and genuine regeneration can take place.
At the same time, many people experience the opposite. Light sources, sounds, stress, digital stimuli and technical devices accompany us late into the night. For many, lack of sleep has almost become the new normal – not because they spend too little time in bed, but because the quality of their sleep suffers.
Our aspiration is to make regeneration a matter of course again. With solutions that do not place additional demands on you but relieve you – naturally, quietly and lastingly. The BioRelax mattress topper is our answer to this aspiration.
For us, sleeping naturally means giving the body room for regeneration at night.
The BioRelax mattress topper supports this process – without electricity, without electronics, without effort.
What we miss at night, we lack during the day
Sleep is not lost time. It is the foundation for vitality, performance and well-being.
More and more people are paying conscious attention to their sleep – and for good reason. In a daily life shaped by stress, stimuli and the constant presence of technology, the desire for calm, naturalness and genuine regeneration is growing. Sleep is once again being recognised for what it is: the foundation for physical recovery, mental clarity and new energy.
During this time, complex regulatory and renewal processes are activated. The focus shifts towards recovery. The body uses the phase of inactivity for rebuilding and stabilisation. Cellular processes run at full speed: structures are renewed, metabolic processes are adjusted, energy is made available.
Without sufficiently deep sleep phases, these processes can only take place to a limited extent. That is precisely why it is not only the number of hours we spend in bed that counts. What is decisive during those hours is the quality of sleep.
Good sleep needs the right conditions - not more complexity
Often it is simple changes that make sleep more restful again.
If poor sleep affects so many areas of our well-being, one question inevitably arises: how do we create conditions under which the body can regenerate again at night?
Often it is not complex measures but conscious, simple changes that bring sleep back into balance. What supports sleep-friendly nights:
Reduce light: Dimmed light in the evening and darkness at night support the natural biorhythm.
Minimise noise: Quiet or steady background sounds help the body to relax more deeply.
Reduce stress: Fixed evening routines and conscious transitions from day to night encourage you to switch off.
Use technology consciously: The bedroom may become quiet – including in technical terms. Doing without mains-powered devices and electronics reduces electromagnetic fields and supports a sleep environment designed for naturalness and calm.
The BioRelax mattress topper adds precisely this aspect to a consciously designed sleep environment: a gentle, electricity-free technology that supports natural regeneration processes during sleep – without electronics, without disturbance, without additional effort.
The BioRelax mattress topper is a medical device developed and manufactured in Germany, based on the Kleinsche Fields Technology –
a form of magnetic field application that deliberately works without electricity, electronics or complicated technology.
Magnetic field application in its most original form - the Kleinsche Fields Technology
A conscious decision in favour of naturalness - a technology without electricity, without electronics, without artificial impulses.
At the heart of the BioRelax mattress topper, the original Kleinsche Fields Technology is at work – static, permanently active magnetic fields in their most natural form. Unlike technically controlled systems, this technology works entirely without electricity, batteries or electronic control. For the Kleinsche Fields Technology draws on one of the most fundamental physical forces in our environment: magnetism, inspired by the Earth's natural magnetic field.
Therein lies precisely its distinctiveness. There are no programmes, no frequency settings and no artificially generated impulses. The application is silent and free of electrosmog – deliberately pared back and simple.
This is made possible by a special principle: a complex, polymorphic arrangement of many small north and south poles. The poles alternate closely side by side – in varying sizes, shapes, spacings and orientations. This creates a multiform, flat magnetic field with varying field gradients and a low, gently acting field strength.
It is precisely this combination of complex field structure, low intensity and complete freedom from electricity that makes the Kleinsche Fields Technology unique.
Three effects that many users report
Note: individual experiences may vary.
1. A new place of regeneration
Many users describe their sleep environment with the BioRelax Mattress topper as calmer, more harmonious and more soothing.
2. Calmer nights and deeper, uninterrupted sleep
Users frequently report improved sleep quality, less waking during the night and an overall calmer sleep experience.
3. More energy and vitality during the day
More restful nights are often noticeable in the morning – through more freshness, clarity and energy in everyday life.
"Our goal is to make sleep once again what it should be: a source of calm, regeneration and new energy."

Natural support during sleep - how the BioRelax mattress topper works
We are convinced that permanently active magnetic fields can have a regulating effect on cellular regeneration processes.
Our cells work electrically and chemically at the same time. The mitochondria too – the cell's "power stations" – work in this way and can respond to their environment. Current research findings indicate that permanently active, static magnetic fields could influence this environment and support processes connected with cell metabolism and the energy balance - and thus with our capacity for regeneration.
We too are engaged with this question and have carried out initial investigations in order to better understand the effect of permanently active magnetic fields.
Initial indications from our investigations to date suggest that the permanently active Kleinsche Fields can have a positive influence on the health and function of the mitochondria as well as on energy provision.

Can I use the BioRelax mattress topper in an adjustable or electric bed?
Yes. The topper works on all surfaces and in adjustable or electrically operated beds.
How do I care for the mattress topper?
The surface can be wiped down with water and mild soap. For more thorough cleaning, an approved surface disinfectant can be used. Washing machines and tumble dryers are not suitable.
How durable is the BioRelax mattress topper?
The mattress topper is designed for daily, long-term use and is suitable for permanent use.
Can I combine the mattress topper with other products?
Yes. It can be used without any problem together with additional toppers, such as heated blankets or other textile sleep aids – also in combination with other BioRelax products such as seat covers or Pads for everyday use.
Can you feel the effect of the BioRelax mattress topper – and if so, when?
Perception is very individual. Some people describe a changed sense of their body or a calmer sleep atmosphere, others notice no direct change.
As the technology works gently and passively, the focus is not on an acute "sensation" but on the long-term support of natural processes.
How do Kleinsche Fields differ from other systems such as PEMF?
Other systems such as PEMF work with active impulses, frequencies and programmed signal patterns that are generated and controlled by electricity and electronics.
The Kleinsche Fields Technology, by contrast, consists of permanently active, static magnetic fields that work without electricity, without electronics and without frequency control.
Are there scientific studies or investigations on the Kleinsche Fields Technology?
The effect of static magnetic fields has been studied scientifically for years. We too are intensively engaged with this question and carry out our own investigations into the Kleinsche Fields Technology.
Initial results from smaller studies and internal investigations provide promising indications that we are currently exploring further – among other things in collaboration with the mitochondria expert Dr. Brigitte König. Our goal is to understand the underlying cellular processes even better.
Do Kleinsche Fields have side effects?
No, Kleinsche Fields are free of harmful side effects. Kleinsche Fields can even be used by many patients who are categorically excluded as users of other forms of therapy or devices on account of health risks.
