Eight Sleep is an online smart mattress brand. The company specializes in products that incorporate smart technology and sleep-tracking functionality. This review will focus on Eight Sleep’s newest high-tech mattress model, the Eight Sleep Pod 3.

The Pod 3 is an all-foam mattress constructed with comfort layers of polyfoam, followed by support layers of denser polyfoam. The Eight Sleep Pod 3 offers a medium firm feel, which corresponds to a 6 on the 1-10 firmness scale. This ensures noticeable contouring for the body, but not too much sinkage and decent support for people who weigh up to 230 pounds.

The Pod 3 contains an Active Grid layer with rows of sensors that span the surface area of the mattress. These sensors track sleep patterns, breathing and heart rates, and other data from anyone who uses the mattress, and awards a nightly score based on sleep quality and duration. You can access data using the Eight Sleep smart app. The app also allows you to adjust the Pod’s temperature settings. An external water container called The Hub connects to small tubes built into the cover. Simply program the app for your desired temperature setting, then wait a few minutes for the Hub to heat or cool the water before sending it through the tubes. The Hub’s temperature range is 55 to 110 degrees Fahrenheit (12.8 to 43.3 degrees Celsius). Additionally, the app can be used as a white noise machine and an alarm.

Eight Sleep also offers an upgraded model known as the Eight Sleep Pod 3 Max. The Pod 3 Max is a slightly thicker mattress that shares much of the Pod 3’s construction as well as many of its smart features. The bed expands on the original Pod 3 with an additional layer of MaxChill foam, which contains silver, copper, and graphite that are meant to reduce heat retention.

This review will focus solely on the Eight Sleep Pod 3. Read on to learn more about the mattress in terms of construction, pricing, and performance, as well as Eight Sleep’s shipping, return, and warranty policies.

Eight Sleep Pod Pro Cover Video Review

If you’re drawn to the smart technology of an Eight Sleep Pod 3 but don’t want to invest in a new mattress, the Pod 3 Cover will fit right over your existing mattress. In the video below, we explore the Pod Pro Cover, which is a previous model of the Pod 3 Cover. The designs are similar but the Pod Pro 3 Cover features more advanced sensor technology to produce more accurate biometric data. Stay tuned for an updated video review of the Pod Pro 3 Cover.

Mattress Performance

Motion Isolation

The Pod 3 offers good motion isolation. The top polyfoam layer is somewhat responsive and you’ll feel a light bounce on the surface when getting on and off the bed, but the material also absorbs movement to a noticeable degree. You and your sleep partner will notice minimal transfer across the surface. The Pod 3 is also completely silent when bearing weight. If you tend to wake up when your co-sleeper moves around in bed, then the Pod 3 may help reduce nighttime disruptions.

Mattresses with memory foam comfort layers tend to provide the best motion isolation. Polyfoam models like the Pod 3 absorb motion to a slightly lesser extent, but these mattresses still eliminate motion transfer better than most latex, hybrid, and innerspring models.

Pressure Relief

Many people feel pressure in the shoulders, lower back, hips, and other areas. This may be due to sleeping on a mattress that does not provide enough support to these areas, which in turn can interfere with spinal alignment and cause pressure to build up. For this reason, how well (or poorly) a mattress alleviates pressure depends on how much support is needed for your body type.

The 12-inch Pod 3 has a medium firm feel, resulting in a strong, pressure-relieving balance of body-contouring and support. This makes the mattress suitable for many side and back sleepers who weigh up to 230 pounds. They’ll feel some noticeable body-contouring, but shouldn’t sink too much beneath the surface.

Temperature Control

The Pod 3 is one of the only mattress models on the market today that offers active heating and cooling. The external Hub connects to tubes embedded into the cover. Using the Eight Sleep app, you can program the mattress for a temperature anywhere between 55 and 110 degrees Fahrenheit (12.8 to 43.3 degrees Celsius).

The Pod 3’s top foam layers do absorb a bit of heat, as is often the case with all-foam models, but this should not affect the customized temperature settings unless you’re an exceptionally hot sleeper. Almost anyone should be able to find a comfortable setting for their Pod given its wide temperature range.

Edge Support

Edge support is a common issue for all-foam mattresses. Even with a high density, polyfoam cannot withstand compression as well as the coils or latex layers used in other mattress types. As a result, you’ll probably notice a fair amount of sinkage along the perimeter when getting on and off an all-foam bed, and you may not feel comfortable lying too close to the edges.

The Pod 3’s edge support is above average for an all-foam model. Featuring 8 inches of high-density polyfoam, the mattress feels fairly stable along the perimeter. You’ll feel some sinkage, but not enough to make getting in and out of bed too difficult, provided you weigh less than 230 pounds. If your weight exceeds 230 pounds, then you may not feel as comfortable on the Pod 3’s edges.

Ease of Movement

The Eight Sleep Pod 3 is fairly easy to move across, which can be attributed to its polyfoam design. Mattresses with only memory foam layers often sink deeply, making you feel as though you’re stuck in the surface when getting in and out of bed. The Pod 3 doesn’t sink nearly as much thanks to its semi-responsive top polyfoam layer.

That said, people who weigh more than 230 pounds will probably struggle a bit more with this mattress. If you are in this weight group, you may want to consider a mattress with a stronger support system (such as a hybrid or innerspring).


Preferences for sex certainly differ from couple to couple, but most would rather use a responsive mattress for amorous activities. Beds that respond slowly and sink deeply can make you and your partner feel like you are fighting the mattress, and this may restrict movement.

The Pod 3’s top polyfoam layer is fairly responsive, and most people don’t sink too deeply. The conforming layers also provide decent traction. You and your partner can remain in one part of the bed when needed and won’t slip across the surface, but you shouldn’t have trouble changing positions or moving to a different area of the mattress.

Additionally, the Pod 3’s above-average edge support ensures you can use most of the bed’s surface. However, if you and/or your partner weigh more than 230 pounds, you’ll probably feel more secure in the center of the mattress.


When new, mattresses with foam layers release tiny particles known as volatile organic compounds (VOCs). These particles are mostly harmless but they often carry an unpleasant chemical smell many liken to plastic. The Pod 3 is no exception when it comes to these off-gassing smells. After unboxing the mattress, you’ll likely detect some strong odor that will gradually dissipate over the days to come.

The Pod 3’s initial smells should dissipate within one week or less. You may be able to expedite this process by placing the mattress in a well-ventilated room for at least one day before sleeping on it.

Side Sleepers: Generally, side sleepers prefer mattresses with softer surface feels. This position requires extra cushioning for the shoulders and hips in order to align the spine properly, so firmer mattresses may not provide enough padding for side sleepers. The Pod 3 is very well suited to side sleepers who weigh up to 230 pounds. This model’s medium feel and close conforming ensures ample padding for the shoulders and hips.

If you’re a side sleeper who weighs more than 230 pounds, the bed still provides adequate support, but there’s a chance the Pod 3 will feel too soft and sink excessively beneath your shoulders and/or hips.

Back Sleepers: Back sleepers usually prefer firmer mattresses than side sleepers. This position promotes spinal alignment on its own, so enhanced support is needed to prevent the torso and waist from sinking too deeply beneath the surface.

We recommend the Pod 3 for most back sleepers, particularly those under 230 pounds. This model conforms to a noticeable extent, but it won’t sink too much for back sleepers and should keep their bodies on an even plane. However, the Pod 3’s medium firm feel may be a bit too soft for some back sleepers, who may want to opt for a firmer mattress instead.

Stomach Sleepers: Stomach sleepers – like back sleepers – typically prefer more supportive mattresses that offer some conforming but won’t sink too much. The stomach sleeping position is tricky because it is associated with more aches and pains than side or back sleeping. Most of us carry a disproportionate amount of weight in our stomach, so sleeping face-down can cause excessive sinkage unless the mattress has a strong support system.

The Pod 3’s polyfoam layers are fairly sturdy, providing some support for stomach sleepers. The bed’s all-foam construction and medium firm feel, however, will be too soft for some stomach sleepers over 130 pounds, leading to excess sink around the midsection.

Eight Sleep Pod 3 Mattress Review Breakdown

The Pod 3 is a foam smart mattress. The top 1-inch Active Grid layer contains foam and state-of-the-art biometric sensors. A 2-inch comfort layer is made of polyfoam, followed by another 1-inch comfort layer of polyfoam. The polyfoam is a little responsive, creating some bounce on the surface with light conforming. The Pod 3 has a 4-inch transitional layer of FlexSpring Technology polyfoam. Beneath is a support core containing 4 inches of high-density polyfoam.

The Pod 3’s defining features are associated with its sleep-tracking and temperature control functions. The Pod 3’s Active Grid is equipped with small sensors on both sides of the mattress. Along with nighttime movements and sleep positions, these sensors can track heart rate, breathing patterns, and how much time you spend awake and asleep. You can access your personal data using the Eight Sleep app, which is compatible with iOS and Android phones and smart devices. The app is free to download.

The Pod 3 also offers adjustable temperature controls. Water is stored in an external component known as The Hub, which connects to a network of small tubes that run throughout a lightweight water mat built into the cover. You can use the app to set your preferred temperature. The Hub will then heat or cool the water before distributing it throughout the mattress. You can program the mattress for temperature settings anywhere between 55 and 110 degrees Fahrenheit (12.8 to 43.3 degrees Celsius).

The Eight Sleep app has other functions, as well. These include scheduled temperature readings for each side of the bed, daily sleep and health reports, and a temperature-based smart alarm. These features are available to subscribers of 8+, Eight Sleep’s lifetime membership service that is included with every Pod purchase at no extra charge. Eight Sleep also offers an 8+ Pro membership for an additional monthly fee. This subscription includes Temperature Autopilot, a feature that uses biometric feedback to automatically optimize temperature settings during sleep. The subscription also provides sleep coaching and insights drawn from your sleep data, and access to a library of white noise and meditative sounds.
