Water-Based Cooling: The Next Step in Sleep Technology

ChiliSleep vs. Eight Sleep vs. BedJet

For centuries humans have strived for better sleep. The technological advancements brought on during the 21st century helped us make groundbreaking advancements in sleep science, with temperature-regulated sleep at the forefront. 

Sleep Deprivation in America

A recent study found that 35% of Americans get less than the recommended seven hours of sleep each night. [1]

Cooler sleep leads to better sleep, and better sleep can be transformative, affecting your overall quality of life. With so many temperature-regulated sleep systems; water-cooled beds, cooling mattresses, bed fans, and other options available to us, how do we choose which sleep system best suits our individual needs?

Hydro Cool Technology

Do you sleep hot? With our cooling sleep systems, you can stay cooler, sleep deeper, and tackle each day. Select your personalized sleep temperature, ranging from 55 - 115ºF.

We’ll look at the different heating and cooling bed systems available including the OOLER sleep system and Cube Sleep System against the highly recognized BedJet® and Eight Sleep bed system.

For those unfamiliar with thermal sleep systems, here’s a quick primer:

The OOLER®, Cube, and Eight Sleep™ are water-cooled mattress pads, which means water flows through channels in the polyester-fill pad and is heated or cooled to your settings. 

The BedJet® is an air-based cooling and warming sleep system. The system uses air to regulate the temperature under the covers. It’s well known that air holds less thermal conductivity than water, which makes a difference in this arena. 

All two-person sleep systems come equipped with “dual-zone” settings for each side of the bed, meaning you and your significant other have the ability to control the level of warmth or coolness you feel on your side of the bed throughout the night. 

Additionally, all bed systems are simple to set up, requiring no tools or complicated instructions to follow and all claim to save electricity, negating the need for extra heat or air conditioning to be used.

What is the Ideal Sleep Temperature?

One study found that bedroom temperature is one of the most critical factors in achieving quality sleep. The study suggests the optimal sleep temperature should be between 60 - 67ºF, resulting in a good night's sleep. [2]

All sleep systems come with control units, which is what effectively regulates the temperature of the bed. The OOLER®, Cube, and Eight Sleep™ units pump water through attached hoses into the pad channels from water reservoirs within the control units. 

The BedJet® delivers air from your room throughout your bed through a nozzle. Then, using smartphone apps (excluding the Cube), you have the ability to program sleep schedules, pre-cool/preheat your bed, and more.

Advantages of the OOLER & Cube Sleep Systems

With over a decade of clinical research under our belts, the team at ChiliSleep has worked tirelessly to deliver thermal sleep systems that truly make a difference in the lives of thousands of people with all different professional, athletic and health backgrounds.

To this end, we’ve developed sleep systems that fit the needs of all, with designs and functionality that work across the board to make the welcome addition to any sleep routine.

OOLER vs. Eight Sleep Pod Pro Cover vs. Bed Jet

Cost of the Sleep Systems

We will be comparing the price for Queen sized dual-zone sleep systems for each brand. Without factoring in any promo codes, the OOLER® sleep system costs $1,499, while the Cube costs $1099. The Eight Sleep™ Pod Pro Mattress (the most popular option) weighs in at $3,095 and the Pod Pro Cover is priced at $1,795. 

The OOLER® and Cube represent significant cost savings, especially for those who want to give temperature-regulated sleep a try.

Getting Started

When you first set up a thermal sleep system there is a priming phase that must first take place. The OOLER® and Cube require just a few minutes for the hydronic pad to fill with water before it can be turned on, compared to the over 90-minutes for the Eight Sleep™ Pod Pro sleep systems.

Bed Compatibility

Although its setup is easy, the design of the BedJet® leaves your bed with a big, noticeable lump where the blower portion of the system sits on the top of your mattress and under your top sheet. To effectively utilize the dual zones, you must buy the BedJet® air comforter to separate the air being pushed in through the air nozzles.

Buying an Eight Sleep™ Pod Pro means you’re basically buying an entirely new bed; their kit comes with a full mattress, plus the cooling pad and the control unit. Most people already have a bed they love out of a desire to get the best night’s sleep possible. 

If that’s the case, then the OOLER® and Cube fit seamlessly since their design allows you to strap the cooling mattress pad firmly to your existing mattress, no matter the size. The Eight Sleep™ Pod does not sell its pad separately. 

Control Unit Design

While the Eight Sleep™ system comes in one unit for two, its taller height makes it more difficult to tuck away in your bedroom. The OOLER®, however, is only six inches tall, allowing it to hide inconspicuously beneath your bed or bedside table while BedJet® will fit under most beds, depending on the model purchased.

The OOLER® system also offers manual controls for those who don’t want to fuss with the sleep app. The OOLER® control unit also comes equipped with a UV light for self-cleaning. 

If you want to have both people use the Eight Sleep™ (each person controls the side) the account sharing functionality is not intuitive. It also means one person effectively owns the unit and the other person is allowed to use it.

Let’s say you don’t want to use your phone to control your bed. With the OOLER® and Cube, you can control the temperature directly on the control unit. With both Eight Sleep™ and BedJet®, the system requires the use of a wireless remote or Bluetooth app to change temperatures.

Sleep Systems Temperature Adjustments

Do you sleep hot or cold? Do you need to quickly adjust your temperature? The OOLER® is equipped with “boost mode” so you can quickly turn the temperature of your bed up or down for those late nights you want to get to bed as soon as you walk in the door.

Temperature Ranges

Control your personalized bed temperature with the following systems.

  • ChiliSleep OOLER & Cube: 55 - 115ºF
  • Eight Sleep Pod Pro: 55 - 110ºF
  • BedJet 3: 66 - 104ºF

    White Noise Control

    Unlike the Eight Sleep™ Pod Pro and BedJet®, the OOLER® sleep system comes with three white noise settings for personalized noise control. Choose from silent, regular or boost mode depending on how much noise you like to sleep with.

    Key Takeaways

    Like most products, finding the best temperature-regulating sleep solution will depend on your personal circumstances and needs. Hopefully, this quick rundown of the ChiliSleep systems’ advantages will help you make a sound decision.

    If you’re cost-conscious, don’t want to part with your existing bed, want an effective heating and cooling mattress pad that works quickly and don’t mind a few extra bells and whistles on your control unit, we think a ChiliSleep system will get the job done (and well).

    In the end, what matters most to us is that you’re aware of how these are game-changing products for your overall health. By taking the leap into the latest sleep technology, you can ensure that you and your partner wake up each morning ready to seize the day after a truly refreshing night’s sleep.
