Eight Sleep Mattresses


Eight Sleep has a range comprising two smart mattresses that provide users with a great deal of control over their sleep environment as well as extremely helpful data.

By Editorial Team | 16th January 2019

Eight Sleep produces a range of memory foam and hybrid smart mattresses. The company produces two mattresses; the Smart Bed and the Pod. Both of these mattresses can be customized to the individual, and they can also create two different firmness levels within a single mattress. Both of Eight Sleep’s mattresses come with Eight Smart Cover; this monitors sleep patterns, adjusts the temperature, programs alarms, and more. Smart Cover can also provide detailed information to the user about their sleep, something that may be extremely valuable to those with sleep conditions.

Overview and Pricing

As mentioned, Eight Sleep produces two different mattresses:

  • The Pod (newest mattress)
  • The Smart Bed (formerly known as the Jupiter)

The Pod is a mattress with medium firmness. It is constructed with polyfoam and memory foam comfort layers, a polyfoam transitional layer, and a high-density polyfoam support core. The Active Grid layer (located above the comfort system) is linked to the Hub, which is located next to the mattress base and control settings. Each side of the bed can have its temperature manipulated; the estimated range is 55° to 115° Fahrenheit (12° to 46° Celsius). The prices for a Pod mattress ranges from $1,925 up to $2,435, depending on the customer’s chosen mattress size.

The Smart Bed is another mattress with medium firmness. It has a 2-inch reactive foam layer, a 2-inch layer of contouring memory foam that is ideal for hip and back support, a 2-inch transition foam layer to minimize movement transference, and a 4-inch high-density support foam foundation for maximum durability. The prices for a Smart Bed mattress range from $895 up to $1,195, depending on the mattress size the customer wants.

Both mattresses have a slight smell once unpacked, but the odor dissipates fairly quickly. The mattresses are made of premium materials that are certified by Certipur-US, and this guarantees that there are no toxic chemicals in the foams. Uniquely, customers can also track their sleeping patterns and data through the Eight Sleep app, using the Active Grid’s built-in sensors.

These are the sizes available to choose from with Eight Sleep: Full (54″ x 75″ x 11″), Queen (60″ x 80″ x 11″), King (76″ x 80″ x 11″), and King Cal (72″ x 84″ x 11″).

Health Factors

Both of the Eight Sleep mattresses are made using materials designed to offer maximum comfort and support, no matter what position you sleep in. The foam mattresses will shape themselves to your body, while the hybrid mattresses have coils that add an extra layer of comfort and support. However, what truly sets the Eight Sleep mattresses apart is the smart cover.

The smart cover will track your sleep habits and provide you with data that will help you improve your sleep. It tells you how much sleep is ideal for you and manages other aspects of the bed. For example, the smart cover can warm the bed, and they can connect to your other smart devices, such as lighting, thermostats and coffee makers. The cover can also sense what stage of sleep you are in and wake you when you are in your lightest stage within a half-hour of your alarm. All of these features work together to improve the quality of your sleep and ensure that you wake up feeling well-rested.

Comfort Guarantee

Both Eight Sleep mattresses come with a 100-night sleep trial. This means that you can return the mattress at any point within the first 100 days of ownership to receive a full refund. Furthermore, Eight Sleep will cover all transportation and handling fees associated with the return. Thanks to this, you can essentially try the mattress risk-free. Returned mattresses are then donated to charities or recycled.


Eight Sleep provides a 10-year limited warranty for its mattresses. At their sole discretion, the company will repair or replace all mattresses that are thought to be defective. However, the smart tracker cover does not come under the mattress warranty and has its own two-year warranty. The mattress warranty has a number of conditions; for example, the website states that the mattress must be supported by a “firm, flat, solid-surface, non-spring foundation (whether the non-moving type or adjustable type) sufficiently strong to remain flat and firm under the weight of the product and its users.”


The Eight Sleep mattresses have not been on the market long enough yet to judge their lifespans. However, they are made of high-quality materials and should have an average lifespan of at least several years. In order to make the mattresses last as long as possible, it is a good idea to use a mattress pad to keep them clean. They can be cleaned with water and a mild detergent, and the smart cover can be removed and washed in a washing machine.

Key Features
  • Lots of lift in the top foam layers, providing a great level of bounce which keeps the sleeper on top of the mattress
  • Good for back and stomach sleepers due to being a firm bed – ideal for those who need this kind of support during the night
  • Plenty of tech for those wanting to learn about sleep technology and improve their rest time
Eight Sleep Mattress Complaints
  • Doesn’t suit those who want a soft mattress, as it provides medium levels of firmness
  • Not for those who dislike foam mattresses – if you want a spring mattress and prefer coils, it may be smarter to look elsewhere
  • May be uncomfortable for those of a certain weight – Those over 300lbs may benefit from a mattress which is more than 10 inches thick

Eight Sleep App: In-Depth

When you purchase an Eight Sleep mattress, you will be able to make use of a free app which collects data on your sleep each night. This will work either for individuals or couples if your partner wants to share their information in the settings.

Upon opening the app, you’ll see an analysis of how you slept the night before. This will be broken down into a timeline spanning across the entire night, so you’ll be able to examine the time you went to bed, how much time you spent asleep, what the temperature of the room was, how hot or cold the bed was, whether you tossed and turned during the night, information on your heart and respiratory rate and much more. You can also switch between day and night mode within the app, and this will unlock setups which are compatible with smart home devices. For example, if you set the Eight to Night mode, this can also turn off your Philips Hue lights, turn down your Nest thermostat and activate the security system if it’s connected. Upon switching back to Day mode, these actions can either be reversed or switched to a set of new ones. 

The app also features a smart alarm, which will sense when you’re in light sleep and wake you at the right moment for the most refreshing night of sleep. The alarm will sound on your device and can also trigger functions such as firing up your smart coffee maker.

Over time, the app will use its ongoing data collection to learn about your sleep. This will allow it to make suggestions about changes you can make to your sleeping conditions to improve your night of sleep. If you need help falling asleep, the app can also be used to play white noise tracks or sleep meditations. Finally, there is a sleep experiment you can carry out with the app to find out how many hours of sleep will suit you the best.


Eight Sleep provides two different types of high-quality smart beds at very reasonable prices and with a 100-night risk-free trial. The smart cover is an excellent innovation that provides users with genuinely helpful functions and information. Furthermore, Eight Sleep’s latest bed, The Pod, has been described as one of the industry’s best mattresses, courtesy of its proprietary technology which optimizes the temperature to keep sleepers thermoneutral and comfortable.

  • 100-night risk-free trial period with no obligatory break-in timeframe
