How dual zone cooling works
Each side of the bed gets its own control. BedJet says the two air nozzles of its Dual Zone system connect directly into separate air distribution zones in its Cloud Sheet, which lies on top of you, and that both sides can be controlled from a single remote. Sleepme lets you choose one temperature-controlled zone for one sleeper or two for two sleepers on its Chilipad, and says partners can each adjust temperatures, schedules and settings from their own app.
Controls go beyond a thermostat. Sleepme says its nightstand remote shows current temperature, target temperature, humidity and system alerts on a low-glow display, with optional in-bed detection to start a sleep schedule. BedJet says you can set a temperature wake-up trigger instead of a noisy alarm clock, and that its Bluetooth app is available but not required.

What each design is good at
- Air-based (BedJet). BedJet says its system works with your existing bed and bedding, does not change the feel of your mattress, and installs in minutes with no tools. It also lets you pre-program cooling and warming settings for every hour of the night.
- Water-based (Chilipad). Sleepme says its pad fits on top of most mattresses, even adjustable beds, with automatic sleep schedules and a gentle warming wake-up it calls Warm Awake.
- Both can warm as well as cool, which helps couples where one person runs cold.
BedJet claims cooling mattresses and water-based systems cannot pull sweat and heat out of the bed like its air technology. That is a maker claim, not an independent comparison, so focus on fit, maintenance and the temperature range you need.
Questions to ask before buying
- Bed size and split. BedJet offers a size guide for its Dual Zone bundles, including California King and Split King setups, and says BedJet 3 is adjustable bed approved. Chilipad is sold in half and twin sizes for each sleeper.
- Space under the bed. BedJet says it fits under beds with only 6" of clearance.
- Trial and returns. BedJet lists free returns for 60 days; Sleepme lists a 30-night sleep trial.
- Upkeep. Water systems need refilling; Sleepme says its Chilipad 2.0 dock needs fewer refills than before and lists care and maintenance steps.
Cheaper fixes to try first
The National Institute on Aging (NIA) says night sweats are hot flashes that happen at night. If they keep you up, it suggests lowering the temperature in your bedroom, drinking small amounts of cold water before bed, layering your bedding so it can be adjusted as needed, and turning on a fan.
Lower-cost bedding can help too: see our cooling sheets guide, cooling pillow guide and cooling gel mattress topper guide. For a heavier blanket that still breathes, see our cooling weighted blanket guide.
When night sweats need a doctor
NIA notes hot flashes are a common symptom of the menopausal transition and can last for many years. If they disrupt your sleep, talk with your doctor about treatment options; NIA says that before taking hormones for menopause symptoms you should discuss your medical and family history with your doctor, and that you should always talk with your doctor before taking any herb or supplement.
