There's a big gap in your health routine. It's 8 hours long.
A third of your life, unused. Not because you're doing anything wrong – because until now, nothing existed for those hours. KleinMed works through the whole night while you do exactly what you were going to do anyway – sleep.
A mat in your bed. You sleep on it. That's it.
It lies under your sheet and works whenever you're on it. No current, no session, nothing to set. What it does during those hours is the rest of this page.
Why the night decides how you age.
Repair, clean-up, cell renewal – almost everything your body rebuilds, it does while you sleep. Growth hormone peaks. Damaged cells are cleared out. Tissue is restored.
The day sets the stimulus. The night does the work.
Illustrative sleep-stage pattern, one night – not measured data
You don't feel your cells. You feel your days.
Waking up genuinely restored. Energy that still holds at four in the afternoon. Focus when you need it, strength and patience when the day tests you.
That isn't character. That's capacity – and capacity is built overnight.
The first 5,000 people are already sleeping on this technology.
In Europe. Time to help the rest of the world, too.
"When I'm traveling and have to stay in hotels, I always bring my mattress topper with me. It promotes optimal blood circulation and supports the body's natural cell energy."
"These Magnetic Fields are life-changing. And not just for athletic performance. I use the seat cover and the mattress topper – every single day."
"Magnetic fields are part of my personal longevity stack. Not only do I sleep on a KleinMed sleep mat, but I also use the seat cushion to maximize the benefits of the magnetic fields throughout the day. KleinMed also had a custom-sized sleep mat made for me at their factory."
Everything around your recovery got better. The recovery itself got nothing.
What you do by day
Nothing you do by day is the repair. It's the request. Training, red light, sauna, cold – each sets a short, sharp stimulus. The adaptation you're actually paying for happens hours later, in the dark.
What surrounds your night
The whole industry improved the surroundings. Nobody went inside. Better mattresses, cooling, blackout, trackers – all of it improves the conditions around your sleep. None of it supports the work being done inside it.
The surroundings got smarter.
The repair stayed exactly the same.
Let your body do the work itself.
So the best help is the kind that doesn't interfere – with any of the intelligent, controlled processes your body has already decided to run. Because only your body knows what your cells need at night. Our job is to provide the biological foundation.
"Everything humanity has learned about recovery and longevity over the past twenty years is what ultimately led us here."
Learn about our approach →Your mitochondria determine your health.
Almost every cell in your body is powered by mitochondria – its own power plants. They produce over 90% of the energy you run on. Repair, renewal, immune response, thought, movement: everything draws on their work.
How many you have
More power plants means more capacity – and each one working at a lower load.
How well they run
Output matters as much as number. Both can change.
What happens with age
Mitochondrial density declines over the years. It's one of the twelve recognised hallmarks of ageing.
"In our laboratory analyses, this technology showed a clear positive influence on mitochondrial parameters."
See all studies →Broad-spectrum field technology
A static magnetic field with one unusual feature: its internal structure. Polarities, pole shapes, sizes, spacings and strengths vary across the entire surface – and none of that variation is accidental.
A repeating pattern gives the body one thing to respond to. This gives it a calibrated range.
Working out how the parameters relate to one another took us over a decade. We didn't expect it to be that complex. It took far longer than we thought. We got there anyway.
How does it work?
The key was never intensity. It was duration.
Cells are fragile. Overwhelm them and they defend instead of cooperating. So this was built the other way round: a subtle stimulus, present for hours – enough to register, never enough to push.
Nothing that lasts comes from a single strong hit. Only what's repeated – again and again, for years.
It's easy. You do nothing – and still do a lot.
Real talk
You know which routines are good for you. Everyone does. But be honest: do you do them every day? Almost nobody does.
It isn't only discipline
It's exhausting. Every routine needs a slot in your day. Your constant attention. Space in your head. And the willpower to keep it up. You have a finite amount of all four. That's not a flaw – that's having a life.
So they fail
Good protocols fail at the same point: you. Not because they don't work. Because they ask for something. Every day. Forever.
This one doesn't
Your mat asks for nothing. No session, no settings, no reminder. It's already in your bed, and it starts the moment you lie down.
It works on your worst days too.
The honest answers, before you ask.

Why there's no trial period
A strict hygiene law we have to obey. As a registered medical device used in your bed, it falls under strict hygiene regulations – the same rules that protect you from germs and pathogens left by a previous user. Once the seal is broken, we're not permitted to pass it on to anyone. You can lie on it through the sealed wrap to test the feel, and return it within 14 days if unopened.
+
A few situations where we'd say: not yet
Magnetic fields are gentle, but a few situations call for caution first. We recommend waiting in the first 12 months after an organ transplant, during acute internal bleeding, after a concussion, or with epilepsy combined with metal implants. With a pacemaker, the mat can still be used – just keep it at least 1.5 cm away. When in doubt, a quick call to your doctor is the honest first step.

Does it work for everyone?
A law of nature that applies to everyone. Blood carries an electrical charge – and charge responds to alternating magnetic poles. This happens in every human body, regardless of age or health condition. The natural magnetic fields can't be overdosed and cause no side effects – they're safe for everyone. (For exact restrictions, please see the product description in our shop.)

A good fit if
- You already invest in your health and want the hours you're not using.
- You're past the age – or the naive belief – where recovery takes care of itself.
- You've tried protocols that didn't survive a busy month.
- You'd rather have something that works quietly than something you have to manage.
Probably not for you if
- You want something you can feel right away, guaranteed. It's built for your cells – silent and below conscious perception. Many people do notice something. It isn't the point.
- You're looking for a treatment for a specific medical condition. That isn't what this is, however welcome any improvement may be.
A Swiss company. German developers. One shared obsession: better wellbeing now, and healthier ageing for as long as possible.

Wake up like your body actually got the job done.
Nothing changes about your night. Everything changes in it. For a lifetime your body had to do this alone. Tonight, finally, it doesn't have to. We built this because we wanted it ourselves.
