ChiliPad Cube Mattress Cooling Pad Review: Bye Bye, Hot Flashes

ChiliPad Cube Mattress Cooling Pad Review


The ChiliPad Cube Mattress Cooling Pad is the best bed-cooling solution for people suffering from night sweats and hot flashes.  This is because it relies on water-cooling, which provides much faster and longer-lasting cooling relief.

Great choice for: Anyone who experiences hot flashes or sweats.

Avoid if:  You want to cool the top of your body, too. This is a mattress pad, not a full-body cooling system like the BedJet.

If you get hot at night or suffer from hot flashes, then you may find the ChiliPad Cube a gift from God.

Like the Ooler and The Pod, the ChiliPad Cube cools your body by passing water through small tubes in a special mattress pad.

Water-based cooling is not just good for hot flashers but also for those who reside in locations with cold climate or whose feet tend to freeze at night.  Nothing cools or heats your body with more precision than water.

The temperature of the water in the Cube can be set anywhere between 55F and 110F to meet your particular comfort preferences.


  • Wide temperature range
  • Single and double zone options.
  • Remote control.
  • Heats / cools faster than a heating pad or a forced-air system.
  • Safer than a heating pad.
  • Saves energy — when you adjust the thermostat at night.


  • Warms the room when run on high.
  • You may feel the tubes in your back.
  • No adjustable timer or scheduler.

How ChiliPad Cube Cools and Heats

ChiliPad Mattress

Mattress pads warm the bed by using embedded wires.

Other cooling/heating systems like the BedJet use forced air to keep you comfortable.

In contrast, the ChiliPad Cube uses water to cool and heat your body via direct contact with a mattress pad full of water tubes. The Cube warms or cools the water then pumps it through silicon micro-tubes in the pad.

Using buttons on the block or the wireless remote control, you set your desired temperature anywhere between 55-110F – and forget it.

Surprisingly, the unit doesn't include an adjustable timer, which is a significant feature in most heating or cooling pads.

Best Features of ChiliPad Cube

Split Queen (Single) ChiliPad Cube - Single Zone - Heating and Cooling Pad - Fits Your Existing Mattress, Delivers Precise Temperature Control, and Creates the Perfect Sleep Environment

People who sleep hot understand how frustrating it is to find a cooling solution that is effective.

That’s where the ChiliPad Cube comes into the picture.

Customers who experience hot flashes claim it keeps them cool and has improved their sleep experience tremendously.

The water flowing through the tubes can also get up to a toasty 110F warming your body and the bed.

Keep in mind that there's no zoned temperature control, so. if your legs get cold, you cannot warm up the lower portion of the pad.

You can choose the dual zone option for King and Queen sized beds only.  The package comes with a cube for each side of the mattress. Each Cube can be controlled individually, letting you set your temperature differently from your partner.

Pad Comfort

In our testing the pad did not change how the bed felt for the most part.

The tubes are soft and small to make sure that you don’t feel them under the poly-cotton pad.

A couple of customers have said the tubes are noticeable on their backs – but it did not impact their sleep.  We never felt them.

ChiliPad recommends setting up a pad under a fitted sheet to keep it in place and to make it more comfortable.

There's also a strap that is used around the mattress to keep the pad from shifting while you sleep on it.

Pad and Cube Maintenance

pad comfort

The mattress firm recommends adding a 1/4 cup of hydrogen peroxide to your water to keep the machine clean.

This is a bit outdated, however, as other more modern units today like the Ooler use UV light to keep your water free from biologicals.

Check the user manual for specific cleaning procedures.

You also need to ensure that the exhaust and intake vents do not get clogged.

As for the mattress pad, you should wash it in a front loading machine only. Set a gentle cycle for washing and ‘No Heat’ setting for drying out the cube.


The Cube should be placed on the floor next to your bed. It must be on a flat firm surface.

Make sure there is a minimum of 24 inches of space around it to allow unrestricted air intake and exhaust. Do NOT place it under your bed.

Before turning on the Cube, you'll want to make sure you pour water into the reservoir and attach the hose to the Cube.

The company advises using distilled water. This is most likely to prevent biological and mineral buildup.

You will need to clean your Cube regularly if you are using tap water. The Cube can be damaged by too much buildup of mineral deposits which clog the tubes.

Mattress Pad

The mattress pad goes under your fitted sheet and on top of your mattress. Use the included strap to secure it around the mattress and keep it from shifting when you turn while sleeping.

You'll need to make sure you keep sharp objects away from the pad, though, because the tubes are soft and can be easily punctured.

So while the ChiliPad is safe for pets, you'll need to be careful that the tubes don't get damaged by their claws.

We also recommend placing a waterproof mattress protector under your pad in case of leakage.

Remote Control

Split Queen (Single) ChiliPad Cube - Single Zone - Heating and Cooling Pad - Fits Your Existing Mattress, Delivers Precise Temperature Control, and Creates the Perfect Sleep Environment

You will get a wireless remote control included in the package. You have to sync it with the cube to use it.

After plugging in the cube, hold the ON button for 5 seconds until you hear a long beep and the little display reads 888.

Press the ON button, and it is going to pair with the cube automatically. Pairing is confirmed by a short beep.

The remote control contains three buttons: warm, cool and ON/OFF.

You can utilize the functions using the buttons on the remote; or, in case the remote control malfunctions or the battery dies, you can access the same functions using the buttons on the cube.

You can adjust the water temperature between 55F and 110F as mentioned above.

However, there isn't a timer function, which is a huge drawback. Some people prefer to warm the bed just for the first few hours to avoid waking up in a sweat in the middle of the night.

Others favor to turn off cooling as the night progresses and the temperature goes down.

The Cube is only going to turn off automatically after 10 hours.

Light and Sound

The cube generates a mild fan sound that sounds like white noise. You won't hear or sense it most of the time.

You'll get used to it in no time. This device really isn't noisy and won't cause most people any trouble in falling asleep.

In the next generation ChiliPad, the firm has removed the annoying lights that were never turned off in the original unit.

They do light up in the beginning, but after a few moments, indicator lights go off in this one.

Adjusting Temperature

chilipad review

The ChiliPad Cube works best in a room with a moderate temperature. So don't turn your thermostat off completely.  This unit isn't a replacement for whole-room climate control.

Usually, the Cube will achieve your desired temperature within a few minutes after you set it. Air temperature, humidity and Cube positioning may affect the actual temperature achieved on your body, however.

The Cube reaches the preferred temperature faster compared to a conventional heating pad. But if you would like it to be perfect once you get into bed, turn it on and set your desired temperature 30 minutes before you sleep.

For the best results, when you're heating the bed, cover yourself using the blanket or comforter. This will provide insulation by trapping warmth in the bed and heating you up more effectively.

Due to temperature differences between the surrounding and pad atmosphere, you may see the wetness on the pad because of condensation.

Either lower the thermostat or raise the Cube temperature to eliminate it.

Overall Rating

chilipad review

The first-generation ChiliPad Cube would have earned a lower score. However, the company has made many improvements in the latest Cube Pad.

It works faster, is far easier to use, produces less noise and does not include those annoying lights.

The dual zone management is a superb solution for couples that have distinct sleeping preferences.

We like the setup process also. You might have difficulty in finding a place that is suitable for setting up the cube though.

Remember, you can't set up the Cube under your bed.

Overall, the latest ChiliPad is a fantastic solution for the sleepers who get too hot or too cold while sleeping.

That said, the new Ooler (click to see our review) is a better device and offers smartphone control plus variable temperature scheduling throughout the night.


  • Effortless to install and use.
  • Quick temperature changes.
  • Safer than heating pads.
  • Can be machine-washed.
  • Low-water level indicator.



  • No adjustable timer.
  • Cube placement can be challenging in tight bedrooms.

Customer Feedback

Split Queen (Single) ChiliPad Cube - Single Zone - Heating and Cooling Pad - Fits Your Existing Mattress, Delivers Precise Temperature Control, and Creates the Perfect Sleep Environment

The latest-generation ChiliPad Cube has more positive client feedback than their first model.

With the previous version, clients complained about loud beeping sounds, the bright lights, and an unreliable temperature controller.

Buyers of the new ChiliPad say it works fantastically. It can get things as warm or as cold as you want them to be.

It's particularly beneficial for users suffering from night sweats and hot flashes. Those who reside in hot areas say their sleeping experience has improved with it.
