Eight Sleep vs. Chilipad: How do these smart mattress toppers compare?

Getting high-quality sleep is one of the most important factors for your overall well-being. It influences everything from your energy levels to long-term health. 

Consistently missing out on restorative sleep can have serious consequences on your cognitive function, immune system, and mood and lead to chronic conditions like diabetes and heart disease.

Innovative products like Eight Sleep and Chilipad are designed to improve sleep quality by regulating body temperature and creating an ideal sleeping environment. 

In our Eight Sleep vs. Chilipad review, we’ll compare their key features, benefits, and drawbacks to help you decide which solution best fits your needs.

Eight Sleep overview: Premium, AI-powered mattress topper

Source: eightsleep.com

Eight Sleep is a San Francisco-based company that uses advanced technology to transform how people sleep. Their main product is the Eight Sleep Pod — a premium smart mattress topper that circulates water through a series of tubes and uses sensors and artificial intelligence to regulate your body temperature throughout the night. It’s designed to help you fall asleep faster, stay asleep longer, and get more restorative sleep. 

The system also tracks your sleep data without wearables, allowing it to adjust your sleep setup in real time. 

Eight Sleep’s product range includes:

1. Pod 3: Uses older-generation technology and includes a bed cover and a temperature-control hub

2. Pod 4: Includes a bed cover and a temperature-control hub but uses newer technology

3. Pod 4 Ultra: Includes a bed cover and a temperature-control hub, as well as an elevation adjustable base for snoring alleviation

The Eight Sleep Pod is not just a bed cover for temperature control — it uses an AI-powered Autopilot feature that learns about your sleep patterns and makes automatic sleep and posture adjustments throughout the night.

Eight Sleep is one of the most popular sleep solutions on the market. It is endorsed by well-known biohackers and health specialists like Dr. Andrew Huberman, Dr. Peter Attia, Dr. Matthew Walker, and Joe Rogan. It has also helped Bryan Johnson, a millionaire biohacker, achieve a perfect sleep score and maintain his strict sleep routine, as outlined in his blueprint protocol.

Chilipad overview: Quality sleep accessible to everyone

Source: sleep.me

Chilipad is another smart sleep pad and a more affordable Eight Sleep alternative made by Sleepme, formerly known as Chilisleep. It offers a water-operated mattress topper for bedtime temperature control and a sleep tracker that measures sleep performance to make real-time adjustments.

Sleepme’s product line consists of:

1. Chilipad Cube: A mattress topper for temperature control operated with a remote

2. Chilipad Dock Pro: A more comprehensive option with scheduled temperature adjustments via Sleepme app and sleep tracker compatibility

3. Chilipad Dock Pro Bundle: Chilipad mattress topper and sleep tracker for real-time temperature control based on sleep data

Chilipad works with your current mattress, just like Eight Sleep, and it’s designed for one or two people who can adjust their perfect temperature. It also uses artificial intelligence to learn about your sleep habits and patterns and the ideal temperature to prolong and deepen your sleep.

While not as popular as Eight Sleep, Chilipad is also endorsed by many high-profile biohackers and athletes, such as Dan Campbell, Dr. Mark Hyman, Dr. Kelly Starrett, and Tony Robbins.

If you’re looking to get most of Eight Sleep's features at a lower cost, Chilipad may be the right choice. However, the final decision depends on additional factors and features, which we will discuss in more detail below.

Eight Sleep vs. Chilipad: Features and value compared

While Eight Sleep and Chilipad offer similar products and benefits, their features and prices vary greatly. The table below provides a quick overview of the most important aspects you should compare:

| Criteria                   | Eight Sleep                                            | Chilipad                                                      |

In the section below, we’ll compare Chilipad vs. Eight Sleep in more detail, focusing on five key criteria:

1. Technology and main features

2. Sleep tracking and AI-powered temperature control

3. Snoring reduction

4. Pricing

5. User reviews

1. Technology and main features

Source: eightsleep.com

Eight Sleep and Chilipad use similar technology to keep you cool or warm at night but differ slightly in terms of accessories and overall features.

Both the Eight Sleep Pod and Chilipad Dock Pro use a high-tech layer that wraps around your mattress like a fitted sheet and contains tubes for water flow. The fitted sheet is attached to the hub unit, which holds the water for cooling and heating and connects to the app. 

The toppers allow you to control the temperatures individually for each side of the bed, so you and your partner can set the temperature to your liking. Maintaining optimal temperature at night is key to restorative sleep, as temperatures too low or high can wake you up or disrupt your sleep cycles.

Besides the mattress topper, the two companies offer additional features to support your sleep. You can compare them in the table below:

| Eight Sleep features                 | Chilipad features                      |
| ------------------------------------ | -------------------------------------- |
| Automatic temperature with Autopilot | Automatic temperature with Sleepme app |
| Vibration and thermal alarm          | Thermal alarm                          |
| Sleep and health reports             | Schedulable sleep programs             |
| Compatible with any bed              | Airplane mode to limit EMFs            |
| Snoring detection                    | Bedside controls                       |
| Controllable without a phone         | Split bed compatible

2. Sleep tracking and AI-powered temperature control

Both Eight Sleep and Chilipad track your sleep metrics through special sensors embedded in the mattress cover. The tracking happens without any wearables, so there’s nothing to distract you while you sleep.

Each morning, both products will wake you up to a detailed report that includes:

• Time spent in bed

• Time spent sleeping

• Time spent in each sleep stage

• Heart rate

• Heart rate variability

Eight Sleep’s Autopilot AI then uses this information and analyzes it in the context of your age, biological sex, local weather, temperature preferences, bedroom temperature, etc., to craft the ideal environment for your sleep. This feature is included with all Pod models.

Chilipad’s sleep tracker offers the same functionality, and it also tracks your movements throughout the night, as well as your respiration rate. That said, the feature is part of the Dock Pro Bundle, but you can also buy it separately with Dock Pro.

To use Eight Sleep’s Autopilot and Chilipad’s AI system, you’ll need to pay a monthly subscription billed annually. Eight Sleep charges $17/month ($25/month to get a 5-year warranty), while Chilipad charges $5.99/month (the first month is free). Both companies support two accounts per membership, with all reports available in dedicated apps.

3. Eight Sleep vs. Chilipad: Snoring reduction

Source: eightsleep.com

Besides the high-tech mattress cover, Eight Sleep Pod 4 Pro also has an adjustable base designed to reduce snoring. This is one of the most significant differences between Eight Sleep and Chilipad, as the latter does not offer this functionality.

By connecting the base to the sleep tracker app, special sensors analyze vibrations you produce while snoring, and the base elevates your head. According to the company’s studies, this system reduces snoring by up to 45%. The only downside to this feature is that the base lifts the entire bed, which may not suit your partner’s preferred sleeping position. 

Chilipad’s sleep tracker only detects sleep metrics without measuring snoring, so Eight Sleep is a better choice for those with sleep apnea.

4. Chilipad vs. Eight Sleep: Pricing compared

Eight Sleep and Chilipad fall into two completely different price categories. Eight Sleep is a premium product designed for those with a high budget, whereas Chilipad is a more affordable option. You can see the price difference in the table below:

| Product                  | Price                                      |
| ------------------------ | ------------------------------------------ |
| Eight Sleep Pod 3        | $2,295                                     |
| Eight Sleep Pod 4        | $2,649                                     |
| Eight Sleep Pod 4 Ultra  | $4,699                                     |
| Chilipad Cube            | • ME: $649–$749<br>• WE: $1,249–$1,449     |
| Chilipad Dock Pro        | • ME: $1,149–$1,399<br>• WE: $1,899–$2,099 |
| Chilipad Dock Pro Bundle | • ME: $1,593–$1,873<br>• WE: $2,738–$2,958

Chilipad’s most expensive product costs slightly more than Eight Sleep’s most affordable model. Another big difference is that Chilipad sells mattress covers made for one (ME) or two (WE) people. This allows you to purchase the product for much less if you sleep alone. In contrast, Eight Sleep sells two-person covers only, so their offer is not as customizable.

Overall, if you’re a cost-aware buyer and want to get 90% of the functionality of Eight Sleep at a much lower price, Chilipad is the way to go. But if money is not a problem and you want to get the best sleep technology, you can consider Eight Sleep.

5. User reviews and customer satisfaction

Despite their online popularity and strong marketing, both Eight Sleep and Chilipad have many negative online reviews from dissatisfied customers. 

Eight Sleep has a 2.8-star rating on Trustpilot (from 250+ reviews), 48% of which are 1-star reviews. The two main issues users share are leaks and a shorter-than-expected lifespan. Most reviewers state that the product works for 2–3 years, which is less than expected considering the price tag.

Similarly, Chilipad has a 2-star rating based on 15+ reviews, which is not highly representative. Users are typically dissatisfied with poor customer service, leaks, and lost shipments.

On Reddit, most users prefer Eight Sleep over Chilipad, stating that it’s a more premium product overall. Still, those looking to get more value for money typically favor Chilipad. Here’s what one user said:

Takeaway: Can Eight Sleep and Chilipad alone fix your sleep?

Poor body temperature regulation and night sweats are a nagging problem for many people, keeping them awake at night and impacting their overall quality of life. Using Eight Sleep or Chilipad can be a step in the right direction toward solving these issues. Judging by user reviews, they may not be perfect, but they will help you stay cool while sleeping and prevent excessive sweating and soggy sheets.

Still, sleep is a complex process, and your sleep quality is impacted by much more than your bed temperature. Temperature-controlled mattress covers are costly solutions that target symptoms but don’t solve the underlying health issues that lead to excessive sweating and poor body temperature regulation.

Your genes, however, play an essential role in your sleep quality, so understanding your genome is the first step toward taking proactive, personalized steps toward achieving long-term, high-quality sleep.

At-home DNA testing platforms like Nucleus offer a much more affordable solution to understanding your genetic predispositions related to sleep. Nucleus helps you understand the cause of your poor sleep by decoding how your genes interact with your lifestyle and environmental factors. It also guides you in the right direction toward addressing these issues with personalized recommendations.
