Night sweats can make quality sleep feel impossible, and I know firsthand how heat can affect sleep. As a Spencer Institute-certified sleep science coach and veteran mattress tester, I've tried my share of cooling sleep products, and most only help at the surface level. Some sleepers need more advanced tools, like smart mattress toppers and sleep systems, that are designed for all-night temperature regulation. The catch is that these systems can feel less comfortable than a regular mattress topper while costing as much as an actual cooling mattress.
The North Carolina-based company Chilipad by Sleepme also knows a thing or two about heat, and not just humid Southern summers. Sleepme's new Chilipad 2.0 cooling mattress topper launched May 19, and its first two waves of limited-release orders sold out within 48 hours. I spent a week testing it to see whether the system is worth its premium price, especially compared with smart sleep systems like Eight Sleep and Orion Sleep that include sleep tracking.
Now, I understand the appeal: The Chilipad focuses less on sleep metrics and more on comfort, active temperature control, bedside remotes, offline sleep schedules, and a design that felt less intrusive to me than the tube-based systems I've tried.
I think the Chilipad 2.0 is best for people who need serious temperature control, not just casual cooling. Its high price, frequent distilled-water refills, and lack of sleep tracking are real drawbacks, but its comfort and cooling performance make it a strong option for hot sleepers who care more about staying cool through the night than collecting another set of sleep scores.
The Chilipad 2.0 is a water-powered mattress topper that actively heats or cools your bed through app controls, bedside remotes, and scheduled temperature settings, making it useful for hot sleepers and couples with different temperature preferences.

What is the ChiliPad 2.0?
The Chilipad 2.0 is an active temperature-control mattress topper designed to heat or cool your bed using water circulated through a removable Hydrolayer. Unlike passive cooling toppers and mattresses, which rely on breathable foams or cool-to-the-touch covers, the Chilipad actively maintains a set temperature between 55 and 110 degrees throughout the night. It also doesn't rely on tubes, just ultra-thin channels that are less detectable in feel.
The system has two main parts: the Dock and the topper. The Dock acts as the engine, pumping water through the Hydrolayer beneath the cooling cover. The topper fits like a deep-pocketed mattress pad for beds between 10 and 16 inches thick, with padding on top, mesh sides, and elasticized bands to help keep it secure. The Hydrolayer also functions as a waterproof mattress protector, and the cool-to-the-touch cover is washable — a useful care feature that competitors do not typically offer.
It is also different from smart sleep systems like Eight Sleep and Orion Sleep. Those competitors include sleep tracking, heart-rate data, and automatic temperature adjustments based on your body's changes overnight. The Chilipad 2.0 does not track sleep or recovery metrics. Its pitch is simpler: active temperature control with fewer smart-tech distractions. You can adjust the temperature through the Chilipad app or with new bedside touchscreen remotes, and its sleep schedules can run offline.
The Chilipad 2.0 starts at $1,599 and goes up to $3,198, depending on mattress size and whether you choose the solo or dual-sleeper version. The solo option includes one Hydrolayer that covers half of a full, queen, king, or split king mattress; the only solo version that covers the entire mattress is twin XL.
The system is HSA/FSA eligible with medical necessity, which may help offset the cost for people dealing with overheating or night sweats. It comes with a 30-night sleep trial and a two-year limited manufacturer's warranty, with an optional three-year accidental damage plan available for $398 that covers accidental damage caused by pets, mishandling, or defective parts.
Setup and first impressions
At first glance, the delivery and overall "topper" design of the Chilipad 2.0 isn't atypical of what I've seen with industry giant Eight Sleep or fellow newcomer, Orion Sleep. All three sit atop your mattress and use a separate control unit filled with water.
The Chilipad 2.0 comes in one large box (two if you opt for the dual-sided version) that includes the control dock and a fabric bag. I found the step-by-step written instructions very straightforward, but there's also a QR code you can scan that leads to a YouTube tutorial.
It took a good hour from start to finish to fully establish every component of the Chilipad 2.0 from unzipping each side, unfurling the Hydrozone layers, setting up the app and personalized sleep schedules, and filling the Docks with water to get it up and running. Each Chilipad 2.0 comes with 12 packets of cleaning solution for monthly use—one of which you add to the water tank from the get-go. This was a new feature I hadn't seen in other sleep systems, and it provides peace of mind that the internal system isn't building up problematic gunk or mold. The Chilipad 2.0 only takes distilled water, and make sure you have plenty on hand, as you will need to refill often during its first week of use.
What it's like to sleep on the ChiliPad 2.0
I've appreciated smart cooling systems and toppers as a concept, but not usually in practice. These products rely on internal tubing that pumps water from an under-bed or beside control unit, which allows the topper to actually increase or decrease its surface temperature. While the temperature change is detectable, usually, so is the feeling of these tubes.
My husband argued that the plastic feel of the Hydrolayer was too noticeable, and thus, disruptive for him. Bedsheets didn't stifle the tarp-like feel, and I didn't use a mattress protector since the Hydrolayer is meant to act like one (though during setup, the instructions say you can if you'd like to). While I agree to a certain extent, I still found it far more comfortable than traditional inner tubes poking at me and causing an uneven surface to lie on.
You may still hear some shifting of the plastic if it's not secured tightly enough, and the water hoses may also sputter during the first night of use as they work out any air bubbles. However, this only happened twice when I initially turned it on. When the Dock is running, it creates a low hum that I'd put on par with a white noise machine.
The app helps you control the temperature and indicates when it's time to refill the Dock. You can also control temperature with the touchscreen bedside remotes. These plug separately into the wall, and not the Dock itself. I preferred using it at night over my phone, rolling over to make a quick change and going back to sleep. You can also link with Google Assistant for voice control, but integrations don't look to be available through other popular smart assistants like Amazon or Apple.
When it's time for bed, it takes about two minutes to reach my preferred temperature of 71 degrees Fahrenheit, and I've programmed it to incrementally warm up at certain intervals to match my body temperature's fluctuations. As part of my daily scheduled programming, the system starts warming up 15 minutes before my 6:15 am wakeup call, gently starting my day rather than a blaring alarm clock.
The best thing about the ChiliPad 2.0
Comfort is the Chilipad 2.0's strongest suit, from providing an even surface to lie on to temperature control. Night sweats can prolong the amount of time it takes to fall asleep or cause you to wake up from overheating. In my case, the Chilipad allowed me to maintain deeper rest. Consulting my sleep tracker, I noticed higher sleep scores, as well as increased REM, core, and deep sleep stages that I'd attribute back to fewer sleep disruptions from not overheating.
Aside from hot sleepers and those who deal with regular night sweats, the Chilipad 2.0 can appeal to couples who prefer different temperatures and want to set each side. Or if only one of you needs temperature control, you can choose the half-bed size.
What I didn't like
My biggest gripe from testing is that it flies through a tank of water every night for the first few nights for each dock you have, so refills become a daily practice. You can't use standard tap water either, as the system specifically takes distilled water. It's an additional cost that can stack up, along with storage space. While refills should not become as frequent over time, it ultimately depends on your temperature settings and how much water the system uses to achieve your preferences.
Additionally, Chilipad 2.0's price range is on par with a cooling mattress. The company has established manufacturing in North Carolina, which drives up the cost. For the performance and features, I'm fine with this. But something to be mindful of, especially when compared to competitor products, is that it doesn't offer sleep tracking. I've found that sleep trackers built into smart systems and mattresses can have skewed data, especially if pets, kids, or co-sleepers are crashing your space. However, the elevated price puts it on par with competitor products that do offer this feature.
What are your alternatives?
There are good alternatives to look at if the Chilipad 2.0 doesn't seem quite right, but the first step is understanding what kind of temperature fluctuations you deal with. General hot sleepers may find that cooling products that help with passive cooling, or the initial feeling of cooling, gets the job done for them. This can take the form of breathable, cooling sheets, cooling toppers, or comforters.
For more advanced cases due to medical conditions, treatments, or general physicality, active temperature control is key. This creates an environment where a consistent temperature is maintained, and where sleep systems like the Chilipad 2.0, Orion Sleep, and Eight Sleep are programmed to help. I was more comfortable sleeping on the Chilipad than with the detectable tubes of its competitors, and I could check my sleep tracker for data if needed. I noticed my sleep data from the Orion or Eight Sleep systems scored lower because the toppers' sensors picked up my dogs jumping into bed with me. I also think the Orion and Eight Sleep's command centers are more obtrusive, and if you want to get the most out of each device, both require a subscription to access all smart data.
All three products require learning curves to get used to the feel of tubing or specialty cooling layers. Another system, BedJet, will require you to get used to the sound of fans blowing onto the surface of your bed, which often causes the top sheet to poof upward. Yet, it can be helpful to turn to when you're tired of night sweats.

The bottom line
As someone who deals with year-round overheating due to medical issues, I usually loathe it when the forecast calls for searing heat. If you're like me, I genuinely feel that the ChiliPad 2.0 is an effective tool for temperature regulation and promoting better sleep. It's become a handy accomplice to my sleep schedule, and I recommend it for people who have exhausted every option and are looking for an effective cooling solution.
