Cool sleep,
deep recovery.
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.
Personalised
Learns and tunes to your body.
Dual-zone
Each side, its own climate.
Pressure relief
A supportive, spinal-friendly feel.
Breathable
Engineered airflow, never clammy.
Premium materials
Soft, durable textiles for nightly use.
Built to last
Sealed, reliable, made for years.
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.
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.
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.
It learns your night and adjusts on its own.
No screens to check, no app to open before bed. Somnia adapts to your body through the night automatically — the same calm, cool climate, every single night.
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.
