Meet the Qimora Sleep Core.
Active water-based thermoregulation.
Engineered for comfort. Designed to disappear.
Cooling and Heating, Redefined.
Perfect sleep starts with the right temperature.
The Qimora Sleep Core uses a discreet water-based system to regulate your mattress surface temperature throughout the night.
The Unit heats or cools water and circulates it through the Pad placed beneath your sheets, creating a stable, personalized sleep environment.
Your mattress and bedding remain exactly the same. Only the temperature changes, helping your body fall asleep faster, sleep deeper and wake up more rested.
The Best Sleep You’ve Ever Had
Two Sleepers.
Two Temperatures.
Enjoy a dedicated 8 °C temperature swing between sides for a zero-compromise sleep,
with the flexibility to power each zone individually for truly personalized comfort
How It Works.
Three components.
One ritual.
Zero complexity.
The Qimora Sleep Core is built around a simple idea: a ritual, not a gadget. Warm or cool your bed. Lie down. Sleep.
The Unit
The Unit heats or cools water to your chosen temperature and circulates it quietly through the system. Set your temperature, and it does the rest.
The Pad
The thermal pad lies directly on your mattress surface, beneath your sheets. Internal tubing circulates water to actively cool or warm your body. No electricity passes through the pad, ever.
Your Sheet
Place your usual sheet on top. Nothing about your bedding setup changes. Qimora fits in; it doesn't take over.
Loved by many.
Made for all.
Pay Once, Use Forever.
Full Experience
Qimora costs once. You own it outright. There are no monthly fees, no premium tiers, no features locked behind a paywall. The full Sleep Core experience is yours from day one, forever.
Physical Interface
You don't need a smartphone to sleep well. Qimora operates with a simple physical interface: no onboarding, no account creation, no notifications. Just you and your bed temperature.
Offline by Design
Qimora contains no Wi-Fi, no Bluetooth, and no wireless modules of any kind. It is engineered to stay out of your digital life: because the bedroom should be a place to disconnect, not connect.
I can have my cold side, and my wife can have its warm side: we don't have to negotiate every night.
As an athlete and personal trainer, I prioritize rest and recovery to optimize my performance.
Qimora became part of my training recovery routine. Better sleep means better performance the next day.
Before Qimora, I waked up so many times at night. A good night sleep is truly invaluable!

Frequently Asked Questions
Is it certified?
Yes. The Qimora Sleep Core is CE and UKCA certified.
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.
What is the power consumption?
The Sleep Core uses a maximum of 210W while cooling and 300W while heating.
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.
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.
Does it replace air conditioning?
It can complement your A/C by helping you stay comfortable at a higher room temperature setpoint, which may reduce how often your A/C runs. The Sleep Core uses a maximum of 210W while cooling, compared to 500–1,500W for a typical room A/C unit. We don't recommend it as a full replacement for A/C on very warm nights.
Is there electricity in the Pad?
No. Temperature is adjusted exclusively via water flow. The Pad contains no electrical components of any kind.
Does it need an app or Wi-Fi?
No. Qimora is fully offline. No app, no account, no wireless connection 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.
Is there a subscription?
No. Never. Qimora is a one-time purchase with no ongoing costs.
