Navien OptiSleep
All Season Pro Sleep System
The temperature of perfect sleep.
All Season Pro Sleep System
Six features that make
the difference
All Season Control.
Whisper Quiet.
Water circulates through the pad to heat or cool your sleep surface across the full range — 64°F to 113°F — in a single system, year-round. COOL+ mode for summer. WARM mode for winter. Switch by season, set once, sleep every night at the temperature that’s right for you. Quiet enough in all modes that most users never notice it’s running.
Dual-Zone
1°F Precision
Queen and King sizes run two completely independent water circuits — one per side. Each sleeper sets their own temperature in 1°F increments. You at 68°F, your partner at 76°F. No averaging, no negotiating, no waking up too hot or too cold. The Single is single-zone, optimized for one.
AI Sleep Sensing
& Auto Control
Set your preferred temperature and the system holds it precisely through the night. Monitor your sleep and control settings from the Navien Sphere for Sleep app — schedules, timers, and real-time adjustments, all from your phone.
15 Built-in
Safety Features
Leak detection, overheat and overcool protection, water level sensing, auto-stop timer, child lock, self-diagnosis, freeze protection, safety fuse, leveling sensor, and more — engineered to the same rigorous standards behind Navien’s home heating systems trusted for 48 years. Every safeguard runs in the background, every night, without any input from you.
Smart Device
Control
The Navien Sphere for Sleep app puts the whole system in your pocket. Schedule your sleep temperature by day of the week. Build custom profiles — temperature, duration, each side independently. Get notified when water is low. Trigger UV sanitizing on demand. Check in from anywhere, adjust on the fly, wake up to exactly what you set. The SleepHub’s front panel is always there when you want to go hands-free.
Easy
Maintenance
Every purchase includes two removable covers — COOL and WARM — each matched to its season. Both unzip and machine-wash in cold water — no tumble dry, no dry cleaning, air dry flat. UV sanitizing runs automatically at regular intervals inside the SleepHub and pad whenever it’s plugged in, with manual top-up available from the Navien Sphere for Sleep app. Bedding Dry Mode removes moisture from the pad between uses. The water circuit is designed to run long-term; we recommend a monthly water refresh to keep it clean. That’s it.

Reviews from our early access program — customers and event attendees who experienced the All Season Pro before public launch.
“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.”
“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.”
The All Season Pro (model EMF502) is an AI-powered sleep temperature system that sits over your existing mattress. A compact SleepHub circulates temperature-controlled water through the pad to cool or warm your sleep surface in precise 1°F increments — year-round, both sides independently.
64°F to 113°F (18–45°C) across two modes: COOL+ for cooling (64–95°F) and WARM for heating (82–113°F). Temperature is set in 1°F increments — a precise degree, not a range or level. Switch freely between modes by season.
Works with most mattresses — innerspring, hybrid, and adjustable bases. Not suitable for latex, memory foam, or sponge-type mattresses. Heat retention in these materials can cause deformation or overheating. Contact us if you have questions about your specific mattress.
Queen and King sizes include two independent water circuits — one per side. Each sleeper sets their own temperature via the app or front panel, completely independently. You might set 68°F while your partner prefers 78°F. The Single is single-zone.
Contactless (non-wearable) sensors detect your sleep stage in real time — light, deep, REM, and wake. The system automatically adjusts temperature throughout the night to optimize conditions for each stage. You can override to manual control at any time.
In WARM mode, the unit operates quietly from the water circulation pump. In COOL+ mode, a fan also runs — similar to a small desk fan. Initial startup runs a brief high-speed pump cycle for 2–3 minutes, then settles. Low-noise operation is a design priority.
No subscription required — not now, not for any feature. One purchase covers the mattress pad, full app access, and all firmware updates. No monthly fees, no premium tiers.
