Meet the Qimora Sleep Core.
Active water-based thermoregulation.
Engineered for comfort. Designed to disappear.
Cooling and Heating, Redefined.
One of the most powerful catalysts for improving sleep quality is temperature.
Your body does not sleep at one fixed temperature. During the night, it naturally cools down, stabilizes, and slowly warms again before waking.
Qimora was designed around this biological rhythm: active bed temperature control, made simple.
Not another sleep tracker.
Not another monthly subscription.
Just a better sleep environment.
Why Qimora.
Why Your
Bed Temperature
Matters
A bedroom can feel comfortable
while your bed is not.
Modern mattresses, toppers, and heavy bedding can trap heat. Some sleepers wake up too warm. Others struggle with cold feet, seasonal temperature changes, or different temperature preferences from their partner.
When your bed is too hot or too cold, your body has to work harder to stay comfortable. Qimora helps create a stable, personalized sleep environment directly where you sleep.
The Science of
Sleep Temperature.
As you prepare to fall asleep, your body begins to release heat. Core body temperature gradually decreases, while changes in skin temperature help the body transition into sleep. This natural process is called thermoregulation, and it plays an important role in sleep onset, sleep depth, and overnight comfort.
Most people focus on room temperature. But the temperature your body actually feels is shaped by your bed: your mattress, sheets, duvet, and the heat trapped around your skin.
That is why Qimora Sleep Core focuses on the bed surface itself.
Hear From Those Who Tried Qimora
I can have my cold side, and my wife can have her warm side: we don't have to negotiate every night.
As an athlete and personal trainer, I prioritise rest and recovery to optimise my performance.
Qimora became part of my training recovery routine. Better sleep means better performance the next day.
You just set it and focus on resting: my nighttime routine has become incredibly simple now.

Active Water-Based Thermoregulation
Pure comfort, zero distractions.
The Qimora Sleep Core heats or cools water and circulates it through a discreet Pad placed beneath your sheets.
The result is precise temperature control directly on the mattress surface, managed entirely by the bedside Unit, without changing your mattress or cooling the entire room.
No electrical circuits or sensors in the Pad.
No Wi-Fi or Bluetooth EMFs.
No mandatory app.
No unnecessary data tracking.
No monthly subscriptions.
Only the temperature changes. Your mattress stays the same. Your sleep environment gets smarter.
Qimora Auto Sleep Function.
Most sleep devices ask you to track more.
Qimora helps you adjust what matters.
Rather than maintaining a static temperature throughout the night, Qimora utilizes pre-set Sleep Maps that mirror your body's biological rhythm. Over an eight-hour window, the system subtly modifies the surface temperature of the bed to align with various sleep stages.
Fall Asleep & Deep Sleep Support
During the first part of the night (within 1.5h that the map is activated), Qimora lowers the bed temperature, supporting the body’s natural cooling process. This helps reduce overheating and creates a more comfortable environment during the phases when the body naturally seeks deeper rest.
REM Stability & Wake-up
After that phase and towards the morning (8th hour), the temperature slowly rises. This creates a more natural and comfortable wake-up experience, helping your body transition from sleep to wakefulness without abrupt temperature discomfort.
00:00 · Lights out
It all starts at 20°
Baseline. The light goes off, blood moves out to the skin, and the body begins to shed heat. Every line on this chart leaves from the same edge.
00:00–02:00 · Deep sleep
The steep descent
Core temperature falls fast — 1 to 4°C under baseline inside the first two hours. It is the sharpest bend of the night, and the deepest sleep sits in it.
02:00–04:00 · The trough
The coldest stretch
The curve flattens at its lowest point and holds. Stay inside the envelope here and the body has nothing to correct for. Drift outside it and you surface.
05:00–08:00 · REM sleep
The climb back to waking
Temperature rises again, gently, for the rest of the night. REM sleep rides that climb — and the final degree is what actually wakes you.
Everything you want to know.
Frequently Asked Questions
Does it replace air conditioning?
The short answer is no, but it serves a very different purpose. An air conditioner pumps heat entirely out of your house. The Sleep Core is a water-based thermoregulating system that actively pulls heat away from your body and exhausts it into your bedroom.
While it will significantly lower your bed surface temperature compared to a regular mattress, no system on the market can act as a 100% replacement for AC during intense summer heatwaves. Because the Unit releases heat into the room, it performs optimally when your bedroom ambient temperature is 24°C or below.
It is a powerful tool for targeted body cooling, but you may still need AC to manage the room itself on the hottest days of the year.
Is there a subscription?
No. Never. Qimora is a one-time purchase with no ongoing costs.
Does it need an app or Wi-Fi?
No. Qimora is fully offline. No app, no account, no wireless connection of any kind.
How loud is it?
The unit produces low-level white noise of approximately 35 dB, measured at 1 metre. Most users describe it as similar to a quiet fan in the background.
How often does it need maintenance?
Very little. Replace the distilled water every 4 months or earlier if the Unit requires it. Occasionally wipe the unit to remove dust. That's it.
Is it certified?
Yes. The Qimora Sleep Core is CE and UKCA certified.
What is the power consumption?
The Sleep Core uses up to 210W while cooling. Heating draws up to 300W for the single zone, or 400W for the dual zone.
Does it change how my mattress feels?
Minimally. The thermal pad makes a negligible difference. Most users describe the surface as around 5% firmer, and 99% report they cannot feel the tubing once they lie down.
Is there electricity in the Pad?
No. Temperature is adjusted exclusively via water flow. The Pad contains no electrical components of any kind.
Is it a medical device?
No. Qimora is not a medical device and makes no clinical claims.
What if the Pad gets stained?
The Pad cover is waterproof. If it becomes stained, replacement covers are available at a fraction of the full product price.
