William and his wife had talked out loud about whether they would both sleep better in separate beds. She is a light sleeper, he wakes up stiff. Before they divided the bedroom, they tried one more thing.
“My wife and I both use it every night. She sleeps better, I have less back pain. The best thing we have bought.”William N., Ireland
What separate beds solve, and what they do not
Separate beds can stop you waking each other up. What they do not do: they help neither body to really recover at night. Anyone who wakes up stiff or unrested alone wakes up stiff or unrested apart as well. The problem is usually not the person next to you, but that neither of your bodies switches back and recovers the way it should.
The actual problem
Two people, two different bodies, two different kinds of tension, on one surface that helps neither of them let go.
With one of you the back stays tense, with the other the head does not come to rest.
Neither is the other one’s fault, and neither is solved by more distance.
That is why a second bedroom rarely delivers what couples hope for: it separates you, but it changes nothing about the night itself.
Does this sound familiar?
These are the situations that come back most often with couples who are thinking about sleeping apart.
- One of you is a light sleeper and wakes from movement or turning over
- The other gets up stiff and needs the morning to loosen up
- You have already talked about a second bedroom or a second bed
- A new mattress or a different pillow did not make the difference you hoped for
- You want to keep sleeping together, but both get up better rested
Recognise yourselves in three or more of these? Then you are in the group the Duo is meant for.
What ANDUFIT does differently
ANDUFIT is a gentle andullation module that goes under your existing mattress. The Duo is two modules, one per side, each side with its own programme and its own intensity. So one side can run a back programme while the other is set to wind down. The same bed, two very different uses. You keep sleeping together, you simply both recover better.

That is what makes the Duo different from a new mattress or a second bedroom: it does not separate you, it works on both of you at once.
What couples say
William’s experience is not a one-off. Across more than 120 verified reviews the same points come back: better sleep, less back pain, a more relaxed morning together.
“Años sin dormir bien y ahora duermo profundo y me levanto descansada. Todavía me cuesta creerlo.”
“La pulsera marca mucho más sueño profundo. De 40 minutos a casi hora y media, asombroso.”
“Mi mujer y yo lo usamos cada noche. Ella duerme mejor, yo tengo menos dolor de espalda. Nuestra mejor compra.”
“Me levantaba con dolor cada mañana. Ahora me levanto sin quejarme. Mi marido no se lo creía.”
What changes measurably

What studies on andullation show
The andullation technology itself has been studied scientifically as well. A study published on PubMed looked at, among other things, the effects on the experience of pain and on physical well-being.
Less pain, a better feeling and lower blood pressure after andullation therapy
Parras-Moltó A, Ribas-Serna J. Dose-Response, 2019;17(2)
-52.3% experience of pain
+45.1% well-being
+34.5% pain threshold lower back
-6.4 / -4.7 mmHg blood pressure
Study with 50 people without a control group, published on PubMed. The pain threshold was measured with a pressure gauge: more pressure was needed before it hurt. ANDUFIT is not a medical device and promises no cure. With persistent complaints, consult your doctor.
What you may still be wondering
Can two people use one device?
The Duo is two modules, one per side, each side with its own programme and its own intensity. So you do not have to agree on anything.
Will I feel my partner’s side?
No, each side works on its own. One side can be running while the other is off.
Does this work through our mattress?
Yes, through mattresses up to 45 cm. With seven intensity levels each side sets how strong it feels.
Is it not simpler to sleep apart?
Separate beds stop you disturbing each other. With recovery they do not help. ANDUFIT works on both: you keep your bed and still both recover better.
What a second bedroom costs
Sleeping apart means a second bed, a second mattress and more space.
And still: night after night the same mediocre recovery, wherever you lie.
The ANDUFIT Duo: one bed, two sides, both rested. Bought once.

14 nights to try
Test ANDUFIT for 14 nights in your own bed and use it the way you would use it in the longer term. If you do not notice a difference, you send it back and get your money back.
What it could do for you
- Two sides, two settings. Each side has its own programme and its own intensity, so you do not have to agree on anything.
- Deep back relaxation. The vibrations travel along your spine and release the tension of the day, right where it builds up.
- Longer REM sleep. A relaxed body reaches deep and REM sleep more easily and stays there longer, so you wake up restored.
- You keep your own bed. The modules go under your existing mattress, up to 45 cm thick. Nothing else changes.
