Mattresses and Pricing

As mentioned, Eight Sleep produce three different mattresses, the Venus+, Jupiter+ and Mars+.

The Venus + is a latex hybrid mattress with four layers. There is a 2-inch premium latex layer that provides bounce and contouring. Next is a 2-inch comfort transition foam layer providing additional comfort and consistent weight distribution to support all body types. The third layer is 4 inches of sleeved coils surrounded by a poly foam layer; this provides extended support, durability and bounce. Finally, there is 3 inches of high-density support foam to provide a durable foundation.

The Jupiter+ is a medium firmness mattress. 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 Mars+ is a medium-soft hybrid mattress of sleeved coils and foam. There is a 2-inch layer of reactive foam that hugs and reacts like latex. Next is a 2-inch comfort transition layer of foam to relieve pressure on the hips and back. It has 4 inches of sleeved coils that are surrounded by poly foam. Finally, there is 3 inches of high-density support foam to provide the best possible foundation.

All of them will have a slight smell once unpacked, but the odor dissipates 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.

All 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 these features work together to improve the quality of your sleep and ensure that you wake up feeling better rested.

Comfort Guarantee

All Eight Sleep mattresses come with a 100-night sleep trial. This means that you can return the mattress at any point in the first 100 days of ownership and 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 one-year warranty. The mattress warranty has a number of conditions, such as that the mattress must be supported by a “firm, flat, solid-surface, non-spring foundation (whether 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.


Eight Sleep provides a high-quality smart bed at a very reasonable price. The smart cover is an excellent innovation that provides users with genuinely helpful functions and information. The range of mattresses ensures that most sleepers are catered for, but those looking for very soft or very hard mattresses may have to look elsewhere. However, thanks to the 100-night risk-free trial, the mattresses are very much worth trying.
