GOOD GEAR RATING — 8/10 STARS

Summary: For anyone who struggles with sleep or thermoregulation, as I do (hello, hormones!), a cooling mattress topper like Sleepme’s Chilipad will be a game-changer. It did take time to set up and wasn’t without issues — but once it worked correctly, my husband and I enjoyed some of the most restful and improved sleep we’ve had in months. It’s safe to say that it’ll be hard to ever go back.

PROS 

  • Thermoregulation: This mattress pad quickly reaches (and stays at!) your preferred temperature, ranging from 55F to 115F.
  • Nightly ease of use: The Sleepme app comes with recurring preset schedules you can use to adjust your temp overnight, including a feature to heat the bed as you wake.
  • Modular and customizable: If you prefer to regulate the temperature on just one side of the bed, you can purchase the “Me” Chilipad, or the “We” for both partners. If you start with a “Me”, you can also easily upgrade to a “We” later.
  • Helpful customer service: Given how complicated the setup can be, their customer service was easy to work with and offered prompt exchanges with overnight shipments.
  • No need to buy a whole new bed: The Chilipad mattress pad goes over your existing mattress up to 18”, and sheets easily fit on afterward.

THINGS TO CONSIDER

  • Setup is timely and requires some engineering prowess.
  • Though there’s a payment plan available, it’s costly, and additional sleep-tracking tools require an extra monthly subscription.
  • The dock size is slightly bulky at 6.5” tall, making it hard to stow under your bed or in a nightstand. It may be worth taking the measurements into consideration before you buy if you’re low on space.

Avid readers may remember that my husband and I run hot when we sleep. Since first posting about this back in 2021, my sweaty tendencies have only increased. And sometimes during hormonal spurts, my feet will heat up uncontrollably. To cope, we had set up a complicated contraption with two fans that ran simultaneously overnight. 

“Avid readers may remember: My husband and I run hot when we sleep.”

It turns out, we’re not alone — a Gallup poll found that “the majority of US adults (57%) report at least occasionally being too hot while sleeping.” And neurologists say resting in a cool, dark room helps prepare your body for sleep, with optimal temperatures between 60–67 degrees. Since I only wanted to fall asleep in a cold bed and didn’t want to wake up freezing, sleeping with multiple fans has been an imperfect solution.

My colleague Katie has long espoused the benefits of a cooling mattress (aka a mattress that uses water to help sleep at your ideal temp). She actually swears by her Eight Sleep pod, but we weren’t necessarily in the market for an entirely new mattress. So when I got the chance to try Sleepme’s Chilipad system that goes with our existing bed, I leaped at the chance. In fact, my husband and I both did — and we chose the “We” Chilipad Dock Pro Bed Cooling System, made for two. 

About Sleepme

Sleepme is on a mission to change the way the world sleeps. Tara Youngblood is the company’s co-founder and Chief Scientific Advisor, and she’s also a trained scientist, physicist, and published author, drawing on her extensive background to improve sleep health in a drug-free, health-forward way. Because both of my parents have sleeping issues and rely on different kinds of sleep medications, I was inspired and impressed by Sleepme’s focus on using sleep tech and hygiene rather than turning immediately to melatonin or Ambien.

Sleepme primarily offers two cooling systems: the Chilipad Cube and the Chilipad Dock Pro (which replaced the Chilipad OOLER model). If you’re not sure which is the best fit for you, you can try their quiz or compare the features here. It seemed the Dock Pro system was quieter, more powerful, and offered more tech features, so we opted for it.

To place an order, you’ll begin by choosing a “Me” or “We” option — for yourself or if you sleep with a partner — along with your bed size ranging from Queen to Cal King. You can add a protection plan for extra coverage, but the system comes with a one-year limited warranty and 30-night sleep trial to begin with. Shipping is free, and orders ship within 1 to 3 business days.

When the cooling mattress pad arrives, you’ll put it over your existing mattress up to 18” tall (more on how the setup went momentarily). Then you can set the bed to temperatures ranging from 55F to 115F. Best of all, it’s WiFi- and Bluetooth-controlled, so you can simply use the app to turn the dock on or off or adjust the temperature. If you need to ever wash it (life happens!), the mattress pad is 100% machine washable and dryable. My favorite feature? Each of us can set up recurring sleep programs within the app — more on that to come, too.

Set up & first impressions

If you order the “We” Dock Pro system, it will arrive in a large, somewhat heavy box (~30 lbs). My husband carried it up to the third floor, but if you can, I recommend putting it on a dolly or cart and wheeling it into your space. When you open the package, you’ll find two smaller boxes — one for each dock. (If you only order the “Me” system, the size and weight will be far more manageable since it’s only one dock to unpack.)

The “We” Dock Pro system comes in a very heavy box, with two docks for each side of the bed.

I hate to break it to you, but the setup is, in fact, the hardest part. You’ll almost definitely want at least two people and an hour or so to set up. You’ll also need to purchase distilled water ahead of time — I recommend two gallons in case you run into trouble, as we did — and identify one outlet per dock you can plug into. 

“You’ll almost definitely want at least two people and an hour or so set aside for setup.”

Once you’ve got your water, outlets, mattress topper, and unpacked docks ready, you’ll take everything off your existing bed and put the cooling pad on the mattress. There will be long tubes extending from parts of the padding to connect to the dock, so you’ll also want to make sure those are securely fastened. Once you’ve connected them, you can put your regular sheets and bedding back on and turn your attention to the dock itself. A note here: These docks are quite big, so they didn’t fit easily under our bed, though they may fit under yours or a bedside table.

After plugging the dock in, before you do anything else, you’ll want to use the Chilisleep System Cleaner included in the packaging to ensure it’s ready to use. You’ll pour the formula in, add distilled water, then run the program per the directions. Afterward, sporadic maintenance is required to keep things in order, but the manual includes directions for that, too.

When ready, you’ll add any remaining distilled water to the reservoir (there’s a line marking where to fill up to), cover it again, and make sure the reservoir is secured. This is key. Because we had issues with our reservoir and a leaky valve in the back, the first few times we used the cooling mattress, it leaked everywhere.

At the time, though, we didn’t know this would happen, so instead we turned the dock on and used the information on the back to register our docks within the SleepMe app and set them up wirelessly. As we started setting different temps, we could feel the cold water filling the mattress pad, and there was an immediate difference. 

“When we turned the docks off, the water wouldn’t go back into the reservoir correctly — so it leaked all over our floor.”

Unfortunately, as we would later learn, when we turned the docks off, the water wouldn’t return to the reservoir properly, so it leaked all over our floor. Because it was a weekend evening, we tried to reach Sleepme’s support, but they weren’t readily available, so we checked Reddit for solutions. A few users mentioned elevating their docks to prevent backflow, so we put ours on chairs and kept towels underneath to minimize the mess. But needless to say, this experience was frustrating.

We eventually got in touch with the Sleepme team, and they were helpful and responsive. We hopped on a real-time call to walk through the issues we were seeing. Eventually, it became clear that the leak was not something we could fix ourselves, so they offered to overnight two new docks to us, and we could return the others. (We later found out the models we were sent were refurbished, so it may be that the problem wasn’t fixed in the first place — something to note if you seem to have troubles, too. But either way, the Sleepme warranty should have you covered should you run into issues.)

The good news is that once we received the new docks, they worked correctly right away. We were able to quickly reconnect them to our apps, run the cleaner, and begin using nightly. To avoid future leaks, we ended up placing the docks in trays, and luckily, we haven’t had any problems since.

And — because we’re in the middle of a Hotlanta summer — this has been a welcome reprieve.

The Sleepme experience

We’ve now been testing the “We” Chilipad Dock System for close to a month, and I can confidently say: It’s greatly improved our sleep quality. 

My husband and I each have our own automated routine that we’ve built within the app. For me, my side of the bed will begin cooling down to about 70–72 degrees around 10 p.m. (I tried going down to 65 and found myself freezing by the middle of the night — a testament to the fact that it does stay cool!) By the time I try to fall asleep around 11 p.m., it gets a few degrees hotter, then rises to about 80 degrees in the middle of the night as I enter REM sleep. Some nights, I’ll leave it at that temperature until the morning, but other nights, it’ll shut off early so I can wake up at my natural temp.

My husband’s side of the bed begins cooling down to 68 degrees around 10 p.m., peaking at 78 degrees right before his alarm goes off.

You can schedule distinct temperatures and schedules on the “We” models, so each person can enjoy exactly the temperature they want without interference.

In total, it takes about 5–10 minutes to cool to our preferred temperatures, though if your home is warmer, it might take a little longer. We’ve both found that the mattress pad stays cool all night long, and the coolness doesn’t transfer either — I don’t feel my husband’s colder side, and he doesn’t feel my warmer side. And for curious minds: The cooling mattress feels slightly less comfortable than our old topper, but it’s easy to adjust to within minutes.

“We both have found that the mattress pad stays cool all night long, and the coolness doesn’t transfer either — I don’t feel my husband’s colder mattress and he doesn’t feel my warmer side.”

There is a separately sold Sleep Tracker you can purchase to adjust the temperature based on your real-time sleep metrics (like deep sleep, REM cycles, etc.), but I find that I can use my Oura ring data to set this manually. (And a pro-tip: There’s also a Warm Awake feature that warms up the bed to about 115F as you rise for the day, but it feels a little too warm for us personally, so we don’t use it — but if you’re a cold sleeper or like the feeling of a sauna, you might want to try it! We might try it again in the winter.)

And a note for those who choose not to use the recurring sleep programs: You’ll need to manually turn off the Chilipad each morning, otherwise it’ll stay on all day. I learned this the hard way, and am now living in fear of my electric bill. 

Is the Chilipad worth it?

Overall, despite the setup issues and the slightly bulky, less-than-ideal size, I find that the Chilipad system has been a worthwhile investment for our sleep. As I’ve tracked my sleep health, I’ve seen a noticeable difference in my sleep score and even more consistent sleep patterns. Plus, my husband and I both wake up feeling more comfortable (and less sweaty), and we no longer need any fans.

Depending on whether you’re buying one or two docks and the size of your bed, the price ranges from $1,049 to $2,099, though they seem to have frequent sales for several hundred dollars off. And while there are payment plans available, this ain’t cheap — so if you can easily sleep eight hours a night under any temperature, it’s probably not worth looking into. However, if you give it a try and aren’t thrilled with the experience, Sleepme offers a 30-night Sleep Trial Guarantee for a full refund. They also seem to have an accessible customer support service as we learned from our experience — shout out to Dawn R. for walking us through the exchange process and making it easy.

If you want a more affordable alternative to an Eight Sleep pod, prefer tracking wearables, are open to paying the $6/mo subscription for real-time adjustments/or have sleep issues and prioritize sleep hygiene/quality, then it’s worth it. After all, you do spend a third of your life resting — and that’s always worth investing in.
