If you wake up sweaty or fight over the thermostat with a partner, the best bed cooling system can change your nights more than a new mattress. Active systems push cooled air or water under your covers, and many of them also heat, so they earn their keep in winter too. We compared specs, expert testing and owner reviews to pick eight options, from dual-zone climate systems to simple fans and cooling pads.

1. BedJet 3 Climate Comfort System: Best Overall
BedJet 3 is the bed cooling system most experts start with because it is simple: a low-profile unit beside or under the bed blows cooled or heated air through a hose and nozzle under your covers. There is no water to manage, it fits any bed size including adjustable bases, and the maker lists a 66-109°F range. Heat mode warms a cold bed in minutes, which makes it a true four-season system. Cooling works best in rooms below about 79°F, since it moves room air rather than refrigerating it.
Key specs
- Type: air-based, cools and heats
- Temperature range: 66-109°F (maker figure)
- Controls: backlit remote plus free Bluetooth app
- Noise: about 38-43 dB in Sleep Foundation testing
- Fits: any bed size; needs about 6 in of under-bed clearance
- Warranty: 2 years; 60-night trial
👍 Pros

👎 Cons

What owners say: Owners love how fast it warms the bed and how much it cuts night sweats, plus the handy remote. Some say they need a high fan speed in hot climates and occasionally override the automatic modes.
2. BedJet 3 Dual Zone Climate Comfort System: Best for Couples
When one partner runs hot and the other runs cold, a dual-zone setup ends the blanket wars. BedJet’s Dual Zone kit pairs two compact units with a Dual Zone Cloud Sheet that keeps a separate air chamber on each side, so one person can cool while the other warms. It comes in Queen, King and Adjustable Split King versions, and one remote can control both sides.
Key specs
- Type: air-based, two independent zones
- Temperature range: 66-109°F
- Sizes: Queen, King, Adjustable Split King
- Units: about 12.75 x 8.5 x 5 in each; 5 in clearance
- Warranty: 2 years; 60-night trial
👍 Pros

👎 Cons

What owners say: Couples with different temperature needs say it delivers on its promise. Price and the visible hardware around the bed are the main drawbacks mentioned.
3. Chilipad Dock Pro with Cool Mesh: Best Temperature Range
The Dock Pro (now sold by Sleepme as Chilipad 1.0) circulates temperature-controlled water through a thin mesh topper, which gives it the widest range here at 55-115°F. Water systems feel more like a cool or warm surface than a breeze, and many hot sleepers prefer that. For couples, you buy a second half-bed pad and dock. The trade-offs are upkeep, since it needs distilled water and regular cleaning, and Wi-Fi dependence for scheduling.
Key specs
- Type: water-based, cools and heats
- Temperature range: 55-115°F
- Controls: app (Wi-Fi) with on-unit fallback; works with Google Home
- Upkeep: distilled water only; drain and clean about monthly
- Subscription: none
- Warranty: 1 year limited, extendable to 2
👍 Pros
|
👎 Cons
|
What owners say: Testers like the range and how easy it is to set a temperature. Noise, reliance on Wi-Fi, maintenance and cost come up most as downsides.
4. Chilipad Cube: Best Budget Water System
The Cube is Sleepme’s simpler water-based system: no app, no Wi-Fi and no account, just on-unit buttons and a remote. It runs from 60-115°F, has a machine-washable pad with no wires inside, and comes in half-bed sizes so each partner can have their own. It costs less than the Dock Pro but has an audible hum and needs the same distilled-water care.
Key specs
- Type: water-based, cools and heats
- Temperature range: 60-115°F
- Controls: on-unit buttons and remote; no app
- Sizes: half Queen, half King, half Cal King
- Warranty: 1 year limited, extendable to 2
👍 Pros
|
👎 Cons
|
What owners say: Reviewers like the temperature range and washable pad. Noise and the cleaning routine are the common complaints.
5. BedJet 3 with Cloud Sheet Bundle: Best for Maximum Air Effect
BedJet’s Cloud Sheet is a cotton sheet with built-in air channels that spreads the airflow across the bed instead of pooling it near the nozzle. Sleepopolis’s tester felt a stronger temperature change with the sheet than with the hose under a regular comforter. The bundle gets you both in one purchase, with the same specs, remote and app as the standard BedJet 3.
Key specs
- Type: air-based, cools and heats
- Temperature range: 66-109°F
- Includes: BedJet 3 unit plus cotton Cloud Sheet (size varies by listing)
- Warranty: 2 years
👍 Pros
|
👎 Cons
|
What owners say: Owners who add the Cloud Sheet often say it makes the BedJet feel noticeably more effective. The added cost is the main complaint.
6. Certified Refurbished BedJet 3 Dual Zone: Best Value for Couples
If the new Dual Zone kit is out of budget, BedJet sells certified refurbished systems, including a Dual Zone King with Cloud Sheet on Amazon. You get the same independent heating and cooling on each side. Before you buy, read the listing’s warranty and return terms closely, because refurbished BedJet sales on the brand’s own site are final.
Key specs
- Type: air-based, two independent zones
- Temperature range: 66-109°F
- Includes: two units and a Dual Zone Cloud Sheet (King)
👍 Pros
|
👎 Cons
|
What owners say: Buyers choose it to save money on the same hardware. Check the warranty details, since terms differ from new units.
7. Bedfan Version 1.5: Best Cheap Active Airflow
Bedfan is a Texas-made fan that sits at the foot of the bed and blows room air between your sheets, with variable speed from off to high. It does not chill the air or heat at all, but for people who mainly feel trapped heat under the covers it is a big upgrade for very little money. Pick the version that matches your bed height: 1.5-B for beds 19-29 inches tall or 1.5-A for 27-37 inches.
Key specs
- Type: fan only, cooling by airflow
- Speed: variable, off to high
- Sizes: 1.5-B for 19-29 in beds, 1.5-A for 27-37 in beds
👍 Pros
|
👎 Cons
|
What owners say: Fans of the design like its simplicity and how quickly it clears heat from under the covers. It will not help much if the bedroom itself is hot.
8. Slumber Cloud Performance Mattress Pad: Best Passive Option
Not ready for a machine by your bed? Slumber Cloud’s Performance Mattress Pad uses Outlast phase-change material to absorb and release body heat, with a TENCEL lyocell top. It is silent, needs no power and fits mattresses up to 20 inches deep. The effect is gentler than an active system and it does not heat, but it is an easy first step for mild overheating.
Key specs
- Type: passive phase-change pad, no power
- Materials: TENCEL lyocell top, polyester fill; OEKO-TEX certified
- Sizes: Twin through Cal King and Split King; fits up to 20 in deep
- Care: machine wash cold, tumble dry low
- Trial: 30 nights
👍 Pros
|
👎 Cons
|
What owners say: Buyers like that it takes the edge off heat without any setup. Very hot sleepers usually find it is not enough on its own.
How to choose the best bed cooling system
- Air vs water: Air systems like BedJet need no water and heat quickly, but you hear the fan and they cool less in a hot room. Water systems like Chilipad reach a wider range through a thin pad but need ongoing care.
- Maintenance: Chilipad units take distilled water only and should be drained and cleaned about monthly. BedJet has a washable filter. Passive pads just go in the wash.
- Noise: Every powered system makes some sound. If you are a light sleeper, compare published noise figures and expect a fan or hum.
- Dual zone for couples: Look for a true dual-zone kit, or plan on two half-bed units, so each person sets their own temperature.
- Heating for winter: BedJet warms to 109°F and Chilipad models to 115°F. Fans and phase-change pads only cool.
- Subscriptions and connectivity: BedJet and Sleepme need no subscription. Some smart covers require a yearly plan, so check before you buy.
- Bed compatibility: Check under-bed clearance for air units, mattress depth for pads, and keep tubes and hoses away from pets that chew.
FAQ
Does BedJet use water?
No. BedJet is air-based. It blows cooled or heated air under your covers or into its Cloud Sheet, so there is no tank to fill or clean.
What kind of water goes in a Chilipad?
Distilled water only. Sleepme and Sleep Foundation note that tap water can leave mineral deposits that clog the system, and regular cleaning is recommended.
Can a bed cooling system also heat the bed?
Many can. BedJet heats up to about 109°F and Chilipad models up to 115°F, which makes them useful all year. Under-sheet fans and phase-change pads only cool. Follow the manufacturer’s guidance on heat settings.
Is a bed cooling system worth it compared with a cooling mattress?
A cooling mattress only slows heat buildup, while an active system actually sets the temperature in your bed and can heat in winter. If you already like your mattress, an active system is often the bigger upgrade. If you are shopping for a new bed anyway, see our cooling mattress guide below.
