Smart Water Channel Heating & Cooling System
Designed to restore your night's sleep and renew your days
Introducing Somnia
Turn any mattress into a recovery system.
A cooler bed is one of the strongest drivers of deep, restorative sleep. Somnia senses how you sleep and fine-tunes your microclimate through the night — everything below, in one quiet system.
Cooling
A cool, even surface, held all night.
Heating
Gentle warmth before you climb in.
Dual-zone
Each side, its own climate.
Breathable
Engineered airflow, never clammy.
Premium materials
Soft, durable textiles for nightly use.
Built to last
Sealed, reliable, made for years.
Cooling
Cools up to 12°C below room temperature.
When your body needs to shed heat, Somnia draws it away — steadily and silently. No fans, no noise, just a cool, even surface that holds through the night so you fall asleep faster and stay asleep.
Heating
Warms gently to 43°C on cold nights.
The same water that cools you can warm you. Somnia brings the bed up to a comfortable temperature before you climb in, and eases off as you drift — so you never wake up too hot or too cold.
Dual-zone
Two sleepers. Two climates.
One mattress.
He runs hot, she runs cold — and Somnia lets each side of the bed set its own temperature, independently. Comfort was never one-size-fits-all.
16°C Cool
30°C Warm
THE POD · SLEEP SCIENCE
Active recovery, while you sleep
The Pod doesn't just cool the bed — it adjusts temperature to your sleep stage in real time to deepen recovery, night after night.
Active recovery, while you sleep
The Pod doesn't just cool the bed — it adjusts temperature to your sleep stage in real time to deepen recovery, night after night.
Deeper, more restorative sleep
Dynamically adjusting bed temperature by sleep stage increases deep sleep and reduces time spent awake after falling asleep, especially for below-average sleepers.
Measurable cardiovascular recovery
In a 262-member study, sleeping heart rate dropped ~2% (-1 bpm) and heart rate variability improved ~10% (+3 ms) after two weeks on the Pod.
Precision thermal regulation
The Pod automatically adjusts each side of the bed as low as 55°F and as high as 110°F based on your sleep stage and biometrics.
Active recovery, while you sleep
Temperature is everything for sleep.
Adjust it for your bed, not your room — and let your body do the rest. Somnia tunes your surface to your sleep stage in real time to deepen recovery, night after night.
Deeper, more restorative sleep
Matching temperature to your sleep stage helps increase deep sleep and reduce time awake after falling asleep.
Better overnight recovery
A stable, cooler sleep surface supports your body's natural cardiovascular recovery through the night.
Improved sleep comfort
Faster muscle recovery
Prolonged deep sleep
Deep fatigue relief
Suitable for all sleepers

Water-based precision
A microclimate, engineered to the degree.
Water carries heat far more effectively than air — which is how Somnia stays silent, steady and precise where fan-based covers can't.
- Constant cooling up to 12°C below room temperature
- Rapid heat & cool via semiconductor and PTC technology
- Independent left and right zone control
- Sealed, non-leak closed water circulation
- Adjustable 12°C–43°C surface range
- Energy-efficient DC inverter design
The Intelligent Core
The quiet engine beside your bed.
The Somnia Hub heats, cools and circulates water silently — and installs on any mattress, just like a cover.
- Precision cooling and heating in one system
- Cools to 12°C or warms to 43°C, each side independent
- Whisper-quiet — wake naturally, with no sound
- Refilled just every two to three months
- Free shipping, fully set up in minutes
How it works
Two parts. One quiet system.
01 The Hub
Heats, cools and circulates water silently — the quiet engine that sits beside your bed and refills just every two to three months.
02 The Mattress Cover
Closed-loop water channels deliver precise climate edge-to-edge, on either side. It fits your existing mattress, just like a cover.

Questions, answered.
How is this different from a cooling mattress?
Most "cooling" products are passive — a gel layer or breathable foam that feels cool when you lie down, then warms up and stays warm because your body has nowhere to send the heat. Somnia is active: water circulating through the cover continuously carries heat away (or adds it), holding a set temperature all night instead of fading after the first hour. Fan-based covers move air, which is louder, less precise, and far less effective at shifting heat than water — water transfers heat roughly 25 times more efficiently than air.
Will it actually fit my mattress and my bed setup?
