Ooler Sleep System Review

Ooler is a water-based bed temperature control system. It can act as a cooling or heating pad for your bed, depending on the temperature you select between 55F and 115F.

The Ooler sleep system is pricey, but it guarantees you sleep at your most comfortable temperature.

If you struggle with insomnia, hot flushes, night sweats, or cold feet, Ooler will help you sleep better.

Ooler is also an excellent choice for folks who live in cold or hot climates.

Instead of spending a lot of energy on the AC or a space heater, Ooler is much more effective and uses less power.

Read on for our full review of the Ooler sleep system.

If this is not what you were looking for, see our reviews of the best bed air conditioners for other options, including BedJet and Chilipad. We also compare Ooler and these two alternatives further below.

Pros

  • Wide temperature range.
  • Quiet.
  • Easy control via Smartphone.
  • Warm awake silent alarm.
  • UV self-cleaning.
  • Custom scheduling. 

Cons

  • Expensive.
  • Some reports of leaking pads.
  • Cooling ability is limited by ambient temperature.

Unique Features

ooler sleep system

1. Water-Based System With Wide Temperature Range

There are two types of bed temperature control systems: air-based systems like BedJet and water-based systems like Ooler.

The Ooler sleep system consists of a pad with thin tubes inside it. These tubes carry chilled or warmed water from the main unit located either at the foot of your bed or under it.

Ooler’s water-based system cools you better, is quieter, and uses less energy compared to an air temperature control system.

It also allows a broader temperature range. With the Ooler sleep system, you can adjust sleep temperature between 55 and 115 degrees Fahrenheit.

Keep in mind, though, that how cool the pad gets depends on ambient temperature.

2. Half or Full-Size Options

Ooler is available in half bed and full bed options.

If you sleep alone or your partner doesn't need help sleeping warmer or cooler, you can get a half Queen, half King or half Cal King.

If both you and your partner want temperature control, get the full Queen, King or Cal King option depending on the size of your bed.

The full-size options come with two control units, allowing each person to set a different temperature on their side of the bed.

3. Smartphone Remote Control via Bluetooth

Chilisleep, the makers of Ooler, has ditched a physical remote control for app control via Bluetooth.

Normally, we are not big fans of a smartphone controller where a typical remote controller could have sufficed.

Too many companies create buggy apps that are difficult to use and require added efforts to operate the device.

However, Chilisleep has done a great job with the Ooler app. It still has some problems. Sometimes, it takes several tries for Bluetooth to connect.

But it usually works flawlessly. Once you link your phone to the control unit and fire up the app, you can set automatic sleep schedules (with hour-by-hour temperature variations), adjust fan speed and temperature, and set a warm awake silent alarm.

The silent alarm works using science. Your body naturally warms up towards morning. The Ooler sleep system does the same thing - gently increase the temperature to wake you up silently.

If you don't want to use the app, the control unit also has buttons but only for on/off and temperature increase/decrease.

4. Quiet

One of the most significant improvements of the Ooler sleep system over Chilipad is noise level. The Ooler control unit is much quieter, producing as little as 45 decibels of noise.   

It gets a bit noisier when you increase fan speed, but you only set the high fan speeds before you get in bed (to cool or warm the bed quickly), then turn it down to the lowest setting for the rest of the night.

5. Comfortable and Works With Any Mattress

The hydronic pad containing the tubes works with any type of bed and mattress, including adjustable beds.

It includes straps to secure it to the back of your mattress.

And don't worry about the tubes bothering you. The surface of the pad is soft polyester, and there’s also a polyester fiber padding over the tubes so that you won’t feel them.


Issues & Limitations

Expensive

One downside of active bed cooling systems (compared to passive systems like a bamboo cooling topper), is that they are expensive.

The Ooler sleep system is no exception. It costs just as much as a premium memory foam mattress.

If you are looking to sleep cool or warm on a budget, Ooler may not be the best option for you. Try a mattress pad or topper instead.

Limited Performance

While the Ooler sleep system has an impressive temperature range, it usually won’t achieve the max or min temperatures stated.

That’s because its performance is affected by ambient temperature, humidity, and other factors.

Even the manufacturer says that the Ooler sleep system may not be a sufficient replacement for an AC in some cases.

Reports of Leaks

They are not common, but we’ve seen several customers say their pad leaked.

That’s one problem with water-based systems. A small puncture can cause leakage, making the whole system unusable. It can even damage a mattress or the floor.

Check for any leaks when you set up Ooler, and return it if you notice any. Also, be careful to keep sharp objects away from the pad.


Care and Maintenance

The Ooler sleep system comes with a UV self-cleaning feature. This reduces mold formation and bacteria in the control unit and tubes, a common problem with the Chilipad system.

For best performance, Chilisleep recommends adding distilled water to the control unit.

The pad itself is machine washable. Follow the instructions in the manual on how to disconnect and wash it safely.  


Ooler vs. Chilipad

Both Ooler and Chilipad are made by Chilisleep. They are both water-based systems with a similar temperature range.

However, the Ooler sleep system is quieter, making it better for sleep. It’s also more efficient, with a power rating of 140W compared to Chilipad’s 170W.

The control unit of the Ooler system is sleeker and better looking. Most importantly, it’s 1.5 inches shorter than the Chilipad Cube, so that it can easily fit under most beds.

As for features, Ooler comes with Bluetooth connectivity, remote app control, auto-scheduling and a warm awake silent alarm.

Chilipad has none of these features. Instead, it comes with a simple remote control with on/off and temperature buttons.

Price-wise, Chilipad is the cheaper option though not by much.

Which one between Ooler and Chilipad should you get? Go with the Ooler sleep system. It’s only slightly more expensive, but it’s quieter, uses less power, and has more features.


Ooler vs. BedJet V3

Ooler and BedJet are two very different systems. Ooler is water-based, while BedJet is air-based. BedJet cools or warms you by blowing warm or cool air under the sheets.

One notable difference between the two systems is that BedJet delivers faster temperature changes. Ooler takes some time to achieve the selected temperature. 

Another big difference is that BedJet is much cheaper than Ooler.

However, BedJet is pricier to run if you want to keep the bed warm. BedJet can use up to 1500W of power in heat mode while Ooler runs at a steady 140W.

Because water cooling/heating is more efficient, you’ll likely use slightly less electricity running Ooler compared to Bedjet.

That said, both sleep systems actually save you money since you don't have to rely on central AC.

As for noise levels, BedJet is surprisingly quiet when on low and medium settings. Both systems are quiet enough for comfortable sleeping.

In terms of features, both systems share several great features, including hour-by-hour temperature scheduling and a silent temperature alarm.

While Ooler uses a smartphone app to control all the features, BedJet V3 comes with a sleek-looking remote control complete with a screen.

It’s more convenient and easier to use compared to a smartphone app, especially if you don't like bringing your phone to bed.

Which system between BedJet and Ooler should you get?

Go with BedJet V3 if you are on a budget or don't want to use a smartphone app.

BedJet is also the best choice if you don't want to change the feel of your mattress in any way since it doesn't use a pad.

Go with Ooler if you need more cooling or heating; it has a broader temperature range than BedJet (55F to 115F vs. 66F to 104F).

Ooler’s water system is affected less by ambient temperature, making it the best choice if you want to sleep really cool or warm.
