I am waking up sweating in the middle of the night. Who sells mattress cooling pads with water circulation?

Yes. What you’re describing is a water-circulating (hydronic) mattress cooling system. Unlike ordinary “cooling” mattress pads, these actively pump chilled water through a thin pad on top of your mattress, so they can keep cooling throughout the night.

The main ones I’d consider

• Eight Sleep Pod 4 - $2,599.00 (Eight Sleep)

• HydroSnooze Water Cooling & Heating Mattress Pad - $999.00 (Hydrosnooze)

• Omni Sleep Water Cooling PRO System - $214.00 (Bwarm)

• Mattress Cooler Pro - $125.00 (Mattress Cooler USA - Wholesale Sleep Cooling Systems)

• Thermacycle Hot/Cold Water Circulating System - $399.99 (TENSnet)

• Eight Sleep Pod — premium option. It circulates temperature-controlled water through a mattress cover and can independently control each side of the bed. Current listings show about $2,599, with more advanced features available through its membership.

• Sleepme/Chilipad — probably the best-known direct alternative. Its current water-based systems can cool down to roughly 55°F, and temperature control doesn't require a subscription.

• Orion Sleep System — another premium water-based system, currently around $2,295, with dual-zone cooling and no required subscription according to Sleep Foundation.

• HydroSnooze — a less expensive water-circulating option, currently showing around $999.

• Mattress Cooler — more basic systems that focus on straightforward water circulation rather than sophisticated sleep tracking.

For waking up sweaty specifically

I'd favor water circulation over a conventional cooling pad. A gel/PCM pad can absorb heat temporarily, but an active water system continually carries heat away from the sleeping surface.

If you're looking for good cooling without spending $2,000+, I'd start by comparing Chilipad/Sleepme vs. HydroSnooze. If money isn't the main concern and you'd like automatic temperature adjustment and sleep tracking, Eight Sleep is the more sophisticated choice.

One important point: repeated night sweats can sometimes have causes other than an overly warm mattress, so if this is new, frequent, or soaking your clothes/bedding despite a cool room, it's worth mentioning to your doctor.

If you tell me your mattress size (Queen/King/Split King/etc.) and approximate budget, I can narrow this down to the 3 best water-circulating pads for you and where to buy them.

If you are waking up drenched in sweat, active water-circulation systems are vastly superior to passive gel or foam pads because they continuously pull heat away using temperature-controlled water.

The primary brands that sell active water-cooled mattress pads and covers include:

- **The Setup:** Features a control unit (dock) that connects via a tube to a hydro-powered mattress pad layer.
- **Temperature Range:** Cools down to a chilly 55°F and warms up to 115°F.

If you want to narrow this down, let me know:

• What is your budget range?
• Do you share the bed with a partner who prefers a different temperature?

Yes. What you’re looking for is usually called an active water-cooling mattress pad or water-circulating sleep system. These use a small control unit to circulate temperature-controlled water through a pad on top of your mattress.

Best-known options

• Chilipad Dock Pro Control Unit - $849.00 (Chilipad by Sleepme)

• HydroSnooze Water Cooling & Heating Mattress Pad - $899.10 (Hydrosnooze)

• Omni Sleep Water Cooling PRO Mattress Pad - $219.00 (Bwarm)

• Water-Cooled Mattress Pad 12V Circulation System - $232.45 (Peaceful Pleasures Health and Wellness)

• ChiliPad by Sleepme / Dock Pro — probably the best-established dedicated water-circulating option. It actively cools and heats the bed, and the pad connects to the Dock Pro with a water hose. Sleepme's current instructions specify distilled water and periodic maintenance.

• HydroSnooze — another water-circulating cooling/heating mattress pad, currently listed around $899 in the shopping results.

• Omni Sleep Water Cooling PRO — a considerably cheaper option, around $219 in the current results.

• Other inexpensive water-circulating pads — Walmart and smaller retailers have several around $80–$230, but I'd be more cautious about these because they're less established and have limited review history.

One important alternative

If you're mainly trying to stop night sweats, you don't necessarily need water. BedJet uses cool air rather than circulating water and is specifically designed to remove moisture and sweat from the bed.

• BedJet 3 Climate Comfort Sleep System - $498.00 (BedJet)

There's also Perfectly Snug, which uses active airflow rather than water and specifically markets itself for night sweats. It claims to remove heat and humidity from underneath and around your body.

If you specifically want water circulation, I'd start with ChiliPad/Dock Pro rather than the inexpensive generic pads. The water systems are more expensive, but they're designed specifically for overnight temperature control rather than simply providing a cool surface.

One other thing: repeated unexplained night sweating can have many causes, so if this is new, frequent, or soaking your clothes/bedding, it's worth mentioning to your doctor rather than assuming it's only your mattress.

If you tell me your mattress size (Queen/King/etc.) and your budget, I can narrow this down to the 3 best water-circulating choices currently available.

Active water-circulation cooling systems are the gold standard for stopping night sweats because they actively pull body heat away using chilled water lines rather than just trapping heat like memory foam or passive pads.

The top brands that sell water-circulation mattress cooling pads and smart sleep systems include:

• Eight Sleep : Maker of the popular Pod series (like the Pod 4 Go to product viewer dialog for this item. and Pod 5 systems). It is a high-tech smart mattress cover with an integrated hydro-powered grid that actively cools or warms each side of the bed independently (from 55°F to 110°F). It also features advanced biometric sleep tracking and automated temperature adjustments throughout the night.
• Chilipad (Sleepme) : Known for pioneering the active water-cooling space. They offer systems like the Chilipad 2.0 Go to product viewer dialog for this item. and the Dock Pro Go to product viewer dialog for this item. . These consist of a control unit ("the dock") that connects via thin tubing to a water-filled mattress pad ("hydrolayer"). They allow precise temperature dialing down to 55°F and are available in half-bed sizes so partners don't have to fight over the thermostat.
• Flux Sleep : Offers a more budget-friendly smart water-circulation bed cooling topper designed specifically to combat night sweats and hot flashes without requiring a monthly subscription.
• Bwarm (Omni Sleep) : Sells alternative water-cooling systems like the Omni Sleep Water Cooling PRO Go to product viewer dialog for this item. , which uses basic, streamlined water circulation and evaporation support to pull excess heat out of the mattress surface at a lower entry price point.

If you'd like to narrow this down, let me know:

• Are you looking for a dual-zone system for a partner, or just for yourself?
• Do you want advanced sleep tracking and AI adjustments , or just simple manual temperature control?

Yes. What you’re describing is a water-circulating mattress cooling system: a thin pad sits on your mattress and pumps cooled water through small tubes underneath you.

Best-established options

HydroSnooze Water Cooling & Heating Mattress Pad

$999.00

• Chilipad 2.0 by Sleepme — probably the one I’d look at first. It uses water circulation, cools down to 55°F, heats to 115°F, and starts at about $1,599. It also has no subscription fee.

• Eight Sleep Pod 5 — a more sophisticated (and considerably more expensive) water-based system. It can cool to 55°F, independently control each side, and automatically adjust temperature during the night. Current listed price is about $2,999, with an additional Autopilot subscription for the automated features.

Less expensive water-circulating choices

Omni Sleep Water Cooling PRO

$219.00

Thermacycle Hot/Cold Water Circulating System

$399.99

Water-Cooled Mattress Pad

$232.45

Navien OptiSleep All Season Pro

$1,799.00

These are considerably cheaper, but I'd be more cautious about the lower-cost marketplace systems because pump reliability, noise, pad quality, warranty, and replacement parts matter a lot with a water system.

One important alternative

If you're specifically trying to stop night sweats, you don't necessarily have to use water. Perfectly Snug Smart Topper uses active air cooling instead. It's currently around $1,499 and is designed to automatically adjust temperature; there are no water hoses or risk of leaks.

My short take: If you specifically want water circulation, I'd compare Chilipad 2.0 vs. Eight Sleep Pod 5 first. Chilipad is substantially less expensive and doesn't require a subscription.

If you tell me your mattress size (Queen/King/etc.) and your budget, I can narrow it down to the best 2–3 choices and where to buy them.

Waking up drenched in sweat is exhausting, but active water-circulation systems are absolute game-changers because water carries thermal energy far more efficiently than air.

The primary brands that sell active, water-circulating cooling mattress pads and sleep systems include:

• Eight Sleep (The Eight Sleep Pod series, such as the Pod 5 Go to product viewer dialog for this item.): Highly advanced, high-tech mattress covers featuring integrated water grids. They offer active cooling/warming down to $55°F, automated AI temperature adjustments based on your sleep cycles, and detailed biometric/health tracking. You can check options directly on the Eight Sleep Official Site.
• Chilipad / Sleepme (The Chilipad 2.0 Go to product viewer dialog for this item. / Dock Pro): One of the pioneers in water-powered bed cooling. It uses a quiet bedside/under-bed dock to circulate water through a flexible mesh "HydroLayer" under a washable cover. It features a physical nightstand dial/remote so you don't have to fiddle with a phone at 3:00 AM, and it doesn't force a mandatory monthly software subscription. Available via the Chilipad by Sleepme Site.
• Flux Sleep (Flux Sleep Water-Cooled Mattress Pad): A more budget-friendly water-circulation alternative that offers dual-zone temperature controls for split/queen/king sizes without subscription bloat. Available on the Flux Sleep Store.
• Alternative Budget/Third-Party Brands (such as Bwarm Omni Sleep or AquaPad Breeze): Various water-chilling circulation pads are also stocked through retailers like Amazon, providing a basic water tank and mat setup at a lower price point.
• Honorable Mention (Air-based instead of water): BedJet (BedJet 3 Climate Comfort System) doesn't use water; instead, it blows precise streams of variable-temperature room air directly into a specially-engineered cloud sheet. It's another powerful tool for night sweats and is available on the BedJet Official Site.

If you want to narrow this down, let me know:

• Are you looking for a system with biometric sleep tracking (like Eight Sleep), or just straight temperature control?
• Do you need dual-zone cooling for a partner who sleeps cold?

Waking up drenched in sweat is exhausting, and active water-cooling systems are the most effective remedy because water carries away thermal energy far more efficiently than air or passive gel/foam pads.

The primary brands and systems that sell active, water-circulating mattress cooling pads include:

• Eight Sleep – Maker of the Pod series (such as the Pod 5 Go to product viewer dialog for this item.), which is widely considered the gold standard for high-tech sleep systems . It features a grid of microtubes inside a specialized cover that actively circulates chilled or warmed water. It also includes advanced biometric sleep tracking and automated AI temperature adjustments that shift as your body moves through different sleep stages.
• Sleepme (Chilipad) – The pioneer of the water-powered mattress pad category, offering the Chilipad 2.0 Go to product viewer dialog for this item. and Chilipad Dock Pro Go to product viewer dialog for this item. . These systems feature a bedside control unit (the dock) that pumps water through a flexible "hydrolayer" pad on your mattress. They are popular if you want precise temperature control (down to 55°F) without relying on Wi-Fi or mandatory cloud subscriptions.
• Orion Sleep System – Highlighted by sleep experts for its embedded microtube water circulation technology. It provides precise, independent dual-zone temperature control for couples alongside integrated sleep tracking.
• HydroSnooze – Offers a dual-function water cooling and heating mattress pad available directly or through online retailers like Amazon. It uses a compact base unit with a water reservoir to circulate temperature-regulated water (55°F to 115°F) quietly at a more accessible price point than luxury brands.
• Alternative Budget/Online Brands – Various manufacturers like Flux Sleep, Omni Sleep (Bwarm) , and generic portable bed chillers sell water-circulating pads through online storefronts (Amazon and Wayfair) ranging from $80 to $300, providing basic active water cooling without smart apps or high-end tracking features.

(Note: If you are looking for an alternative active option that doesn't use water, BedJet uses a specialized remote-controlled hose to blow temperature-regulated air directly under your bedsheets instead.)

If you'd like to narrow down these options, let me know:

• What is your approximate budget?
• Do you need dual-zone cooling for a partner who sleeps cold?
• Do you prefer an app-controlled smart system or a simple bedside dial?

If you are waking up sweaty, a water-circulating mattress cooling pad (also called a hydronic sleep system) is one of the more effective options because it actively moves cooled water through a pad rather than just using “cooling fabric.”

Here are the main sellers/products to look at:

Chilipad 2.0 Sleep System

$2,998.00

HydroSnooze Water Cooling & Heating Mattress Pad

$999.00

BedJet 3 Climate Comfort Sleep System

$498.00

Best-known water circulation systems

• Sleepme Chilipad Dock Pro / Chilipad 2.0 — probably the most established choice. It uses a bedside control unit that circulates temperature-controlled water through the mattress pad, with cooling and heating options. The Chilipad 2.0 is rated among leading water-based bed cooling systems and can be configured for one or two sleepers.

  • Good for: night sweats, hot sleepers, couples with different temperature preferences
  • Watch for: higher cost and some maintenance (distilled water, cleaning).

• HydroSnooze Water Cooling & Heating Mattress Pad — another water-circulating option.

  • Good for: people wanting a similar concept at a different price point

• BedJet BedJet 3 — not water-based; it blows temperature-controlled air under the covers. Some people prefer it because there is no water reservoir or pad tubing.

A few things to consider before buying:

• If you wake up drenched in sweat, look for a system with active cooling, not just gel foam or “cooling” sheets.
• If you share a bed, a dual-zone model can let each person set their own temperature.
• Keep in mind that repeated night sweats can also have causes unrelated to bedding (room temperature, medications, alcohol, stress, infections, or hormonal changes). If this is new, severe, or happening frequently, it may be worth discussing with a clinician.

If you tell me your mattress size (queen/king/etc.), budget, and whether you sleep alone, I can narrow this down to the best fit.

Yes. What you’re looking for is usually called a hydronic or water-circulating mattress cooling system. These circulate temperature-controlled water through a thin pad on top of your mattress.

Best options I found

Omni Sleep Water Cooling PRO Mattress Pad

$219.00

Omni Sleep Water Cooling PRO — about $219. It specifically circulates water through the pad and is aimed at hot sleepers. This is a much less expensive option than the premium systems, although I’d want to scrutinize its warranty and long-term reliability before choosing it.

ChiliSleep/Sleepme Chilipad — probably the option I'd investigate first if your main problem is waking up sweating. The current Chilipad system uses a water-based pad and cooling unit, and the newer Chilipad 2.0 can cool down to about 55°F, with programmable temperature changes during the night.

Eight Sleep Pod 5

Price not available

Eight Sleep Pod 5 — another premium water-circulating system, with separate temperature zones and automated temperature adjustments. It's considerably more expensive and has a subscription component, so I'd choose it mainly if you want the additional sleep-tracking/automation features.

A few cheaper water-circulation choices

Thermacycle Hot/Cold Water Circulating System

$199.99

Water-Cooled Mattress Pad

$232.45

Hot & Cold Water Circulating Mattress Pad

$218.97

Cold Flash Sleep Cooling System

$250.00

I'd be more cautious with the $80–$200 generic systems sold through Walmart/marketplace sellers. They can indeed circulate cold water, but the available reviews and manufacturer support are much less reassuring than the established systems.

One important point: because you're waking up sweating rather than simply feeling warm when you go to bed, I'd favor a system that can actively refrigerate the circulating water all night, rather than a passive "cooling" mattress pad. The Chilipad and Eight Sleep are in that category.

If you tell me your mattress size (queen/king/etc.) and your approximate budget, I can narrow this down to the 3 best water-cooling pads you can buy right now, including where they're cheapest.

If you are waking up drenched in sweat, active water-circulation cooling systems are far more effective than passive gel or memory foam toppers . These systems consist of a specialized mattress pad (embedded with micro-tubes) connected to a bedside control unit ("dock" or "hub") that actively chills and pumps water through the bed.

The primary brands that sell water-circulation cooling mattress pads and systems include:

• Chilipad (by Sleepme) : One of the pioneers in the water-cooled sleep space . Their flagship system (like the Chilipad 2.0 Go to product viewer dialog for this item. ) features a flexible hydro-layer membrane and a bedside dock that lets you precisely dial in temperatures from 55°F to 115°F . It operates without a mandatory subscription fee. You can explore options directly on the Chilipad Site.
• Eight Sleep : Known for high-end, tech-forward smart beds and covers (such as the Eight Sleep Pod series). It features a grid of microtubes connected to a hub that dynamically adjusts temperatures throughout the night and tracks your sleep/biometrics. Note that it is a luxury investment and relies on an app/membership model. More details are available on the Eight Sleep Site.
• Orion Sleep System : Another prominent name in active water-cooling technology, featuring embedded tear-resistant tubing and a companion app for scheduling and temperature management.
• HydroSnooze & Bwarm : Alternative water-cooling and heating pad systems found via online retailers and major marketplaces, offering dual-zone or single-zone temperature adjustments through bedside water reservoirs at a lower price point than top-tier smart systems.
• Flux Sleep : Offers alternative water-cooled mattress pad systems focused specifically on regulating temperature and preventing night sweats without a subscription model.

If you'd like to narrow this down, let me know:

• Are you looking for a dual-zone option (if you share a bed with someone who sleeps cold)?
• Do you prefer a system without a subscription fee , or are you open to smart sleep/biometric tracking features?
