AI-powered cooling and heating, precise to 1°F. Backed by 48 years of temperature engineering by Navien. No subscription.
Six features that work together to give you the best sleep of your life — every single night.
Cool in summer, warm in winter — one system handles year-round comfort. No seasonal swaps, no compromise. Quiet enough in all modes that most users never notice it’s running.
Your side, their side. Each independently set to the exact degree. No more compromising on temperature with your partner.
Set your ideal temperature and the system holds it precisely all night — no subscriptions, no manual adjustments, just consistent comfort from lights out to wake-up.
See the clinical resultsLeak detection, overheat protection, auto-stop timer, child lock, self-diagnosis, water level sensing, and more — engineered to the same rigorous standards behind Navien’s home heating systems trusted for 48 years.
Control from the Navien Sphere for Sleep app or the SleepHub's front panel display. Set schedules, adjust both zones, and monitor your sleep temperature from anywhere.
All removable covers — both the allergy-care and cooling options — are fully machine-washable. UV hygiene and auto-drain do the rest. No service calls, no fuss.
Your brain uses body temperature as its primary signal to move between sleep stages. Too hot, and deep sleep never fully arrives. Too cold, and you wake before you should. Most bedrooms get neither right — and a fixed thermostat can’t fix it.
While you sleep, the system maintains your precise set temperature all night — so you stay comfortable through every sleep stage without ever adjusting a thing.
One system for cooling in summer, warming in winter — always adapting to your body. Comes with a fitted cover that installs directly over your mattress. Built on 48 years of KD Navien temperature engineering.
Most sleep products give you a few weeks and a restocking fee. We give you a full month, free return shipping, and a complete refund if it doesn’t change how you sleep. Simple return process.
From our early access program — customers and event attendees who experienced the All Season Pro before public launch.
Early Access Event
“I tried the OptiSleep All Season Pro at a Sound Bath event and was blown away. I’ve struggled with sleeping hot for years, and the AI-powered cooling technology is exactly what I’ve been looking for. The tech is seriously cool — I can’t wait to get one at home and finally get a full night’s rest.”
Setup took about 20 minutes. The SleepHub is quieter than my HVAC — I can barely tell it’s on. Three weeks in and my Oura ring is showing better deep sleep scores than I’ve had in years. The AI sleep sensing is surprisingly good at figuring out what you need.
Verified Purchase
“I was skeptical — another sleep gadget, right? But Navien is literally a heating and cooling company. You can feel the engineering. It’s not a startup trying to figure out water circuits; these people have been doing it for decades. That confidence came through the moment I unboxed it.”
I’ve been a hot sleeper my whole life and always assumed I just had to deal with it. Two weeks in and I genuinely don’t recognize my sleep anymore. Wake up twice as rested. The 1°F precision isn’t a marketing claim — you really can feel the difference between 67 and 68.
Genuinely transforms winter sleep. I used to pile on blankets and still wake up cold at 3am — now I set it to 88°F, it’s warm within 10 minutes and holds perfectly all night. Took off one star only because I wish the app had a scheduling feature for weekdays vs. weekends. Minor.
