How Does Eight Sleep Work?
Eight Sleep’s Pod aims to provide intelligent cooling and heating for any bed. Whether you use the mattress or mattress cover, the Pod dynamically heats and cools throughout the night to help you achieve optimal sleep.
Using the Eight Sleep Pod, you can sleep at temperatures as cool as 55°F or as warm as 110°F.
You interact with your Eight Sleep Pod via the mobile App. You input basic information about yourself into the App. Then, the Pod personalizes your sleep preferences. You can also set your temperature, bedtime, and wake-up time via the App.
Some prefer to sleep on a warm mattress with cool blankets at night, for example. Others want a cool mattress with heavy blankets. Some live in warm climates, while others live in cool climates. Eight Sleep’s Pod adjusts to your perfect temperature every night, ensuring a comfortable sleep.
Eight Sleep’s Pod Dynamically Adjust Temperature Throughout the Night
There are other mattress heating and cooling solutions. However, Eight Sleep is one of the few that dynamically adjusts temperature throughout the night in response to sleep cycles.
Each Eight Sleep Pod uses automatic temperature adjustments to maximize your deep sleep. The Pod automatically adjusts temperature based on your preset temperature preferences, sleep history, ambient bedroom temperature, and real-time local weather.
Here is a breakdown of how the temperatures may vary while using your Eight Sleep Pod:
If your bedtime is set for 11:30, your Pod could start cooling your mattress or mattress cover one hour before bed, ensuring it’s ready for your arrival.
During the middle of the night, when you’re at your deepest level of sleep, the Pod could lower the temperature further, ensuring you remain in a deep sleep and at a comfortable temperature for as long as possible.
When you’re ready to wake up, your Pod could gradually raise temperatures, preparing your body for the day ahead.
These temperature adjustments change based on your preferences and local climate. During winter, your Pod can enhance the temperature to promote better deep sleep and reduce it in the morning to help you start your day.
The Eight Sleep App can automatically choose the ideal temperatures according to the time and your sleep phases. Or, you can customize these temperatures within the App. If you want to be cool during deep sleep and warmer during REM, for example, then you can customize that experience with the Eight Sleep App.
You can establish temperature and vibration alarms with the Eight Sleep App. The alarm gradually heats your side of the bed when you need to wake up, then vibrates around the chest area, helping you gently wake up without alerting your partner.
How the Sleep Fitness Score Works
After each night, Eight Sleep’s Pod delivers a Sleep Fitness Score. Understanding your sleep quality can be aided by your score.
Like other sleep tracking systems, the score varies from 0 to 100, with 100 being the best sleep possible.
Unlike other sleep-tracking systems, however, Eight Sleep doesn’t require you to wear a device at night to track your health. The Eight Sleep Pod monitors your sleep and health metrics, which encompass the following:
- Heart rate variance (a measurement of stress)
- Heart rate
- Time slept
- Respiratory rate
- Sleep stages
- Disturbances
After considering all this data, the Eight Sleep Pod calculates your Sleep Fitness Score. Your Sleep Fitness Score considers things like:
- The overall quality of your sleep, including your bedtime and wake-up time consistency, the time it took you to fall asleep, and the time it took to wake up. You receive a score out of 100 based on the overall quality of your sleep.
- Your sleep routine, including how consistently you go to bed and wake up on time and how likely you are to stick to your routine. Eight Sleep’s App gives you a score out of 100.
- The amount of time you slept, including a rating of how that time compares to your usual amount of sleep.
- Your sleep stages include time spent in REM, light, and deep sleep. You’ll receive a higher score if you spend a regular amount in all sleep stages and complete multiple sleep cycles.
If Eight Sleep notices significant health changes, you’ll receive an alert the next day. For example, if it took longer than usual for your heart rate to slow down at night, the App could warn you. You can spot changes to your health earlier.

How to Get Started with Eight Sleep
Transforming your sleep with Eight Sleep is a breeze. Here’s how to get started with the sleep tech system for the first time:
Step 1
Start with a premium mattress base, or bring your mattress. If you’re satisfied, you can purchase the Pod 3 Cover. Alternatively, you can replace it with the Pod 3 Mattress. Both options offer the same core Eight Sleep technology, which includes temperature regulation, sleep tracking, and temperature and vibration alarms.
Step 2
Attach the Active Grid to your bed. Eight Sleep’s Active Grid allows for the continuous absorption and removal of heat from your bed while allowing the mattress and cover to reach temperatures ranging from as cold as 55°F to as warm as 110°F. The Eight Sleep Active Grid lets you sleep comfortably while tracking your sleep patterns using sensors, enabling it to function effectively.
Step 3
Connect the Eight Sleep Hub near your bed to Wi-Fi. The Hub sends water to both sides of the Active Grid, enabling it to regulate the temperature. The Hub also connects to the Eight Sleep app, delivering sleep insights and registering feedback. Inside the Hub is a quad-core proprietary CPU explicitly designed for use in the Pod.
Step 4
You can customize your sleeping experience with the App. The Eight Sleep App enables you to monitor your health and sleep metrics, manage temperature, regulate your side of the Pod, and utilize smart sleep features.
With just four easy steps, you can transform your sleep using the latest advances in smart technology.

Although Eight Sleep may not work for everyone, and temperature control isn’t the right choice for all sleep issues, many like the 30 to 100-day return policy for Eight Sleep, giving you ample time to try the Pod 3 Cover (30 days) or Pod 3 Mattress (100 days).
Ultimately, the only negative reviews for Eight Sleep come from people concerned about the high cost of the Pod 3 Cover and Pod 3 Mattress ($2,000 to $3,000+) along with the subscription ($15 to $24 per month, billed annually). Many also dislike how the mattress’s smart features effectively stop working if you cancel your Eight Sleep subscription.
Industry review organization Sleep Foundation praised Eight Sleep for catering to hot, cold, and data-driven sleepers. However, the company warned pets could damage the material, and the Pod 3 and Pod 3 Max were exceptionally soft, making them less ideal for heavier people (anyone over 130lbs “may sink in too deep,” according to Sleep Foundation).
Eight Sleep has a 2.2-star rating on Trustpilot with 40+ reviews. Most customers have given the company a 1-star rating. Although some customers have praised Eight Sleep for improving their sleep, many customers were disappointed with the pricing model. Others had issues with sleep tracking accuracy or customer service.
