Quick Overview

Eight Sleep, a U.S.-based mattress brand, offers smart mattresses. Each bed comes with the polyester ‘Eight Smart Cover,’ which features a built-in sleep tracker that connects to a wireless app. The cover can track more than a dozen metrics, including time asleep and time awake, heart and respiration rates, and body temperature. The cover also provides a ‘smart alarm’ that wakes up sleepers during period of light sleep; this allows them to feel more rested upon waking. Both sides of the mattress can be individually heated, as well. The Eight Smart Cover can be integrated into the Amazon Echo and other home technology hubs.

Eight Sleep currently sells four individual mattress models equipped with the Eight Smart Cover:

  • The Saturn+ is a memory foam mattress. It features a memory foam comfort layer, polyfoam transitional layer, and 6″ high-density polyfoam support core. The Saturn+ measures 10″ thick and is considered ‘Medium Firm,’ or a 6.5 on the 1-10 firmness scale.
  • The Jupiter+, like the Saturn+, is a memory foam mattress. This model features two memory foam comfort layers, along with a polyfoam transitional layer and a 4″ high-density polyfoam support core. The Jupiter+ measures measures 11″ thick and offers a ‘Medium Firm’ (6.5) feel.
  • The Mars+ is a memory foam hybrid. It is constructed with a memory foam comfort layer, polyfoam transitional layer, 4″ pocketed coil support core, and 3″ high-density foam base. The Mars+, like the Jupiter+, measures 11″ thick and provides a ‘Medium Firm’ (6.5) feel.
  • The Venus+ is a latex hybrid. It is made with a latex comfort layer, polyfoam transitional layer, 4″ pocketed coil support core, and 2″ high-density foam base. The Venus+ measures 11″ thick and is considered ‘Medium Soft’ (4.5).

Please note: Previously, Eight Sleep sold versions of these mattresses that did not come with the Eight Smart Cover, allowing customers to upgrade if needed. However, the brand no longer offers this option; all mattresses include the built-in cover at no extra charge above the listed product price.

Smart sleep tracking is a key advantage of Eight Sleep mattresses, as most competing models do not offer this type of integrated technology. The beds are also constructed with thick comfort layers that isolate motion fairly well and cut down on nighttime noises. Other factors, such as temperature neutrality and edge support, vary by model. Our detailed analysis is below.

Eight Sleep mattresses are available at below-average price-points. Additionally, the brand offers a 10% discount to current students, military veterans, and first responders. The company offers free shipping to customers in the contiguous U.S., and all Eight Sleep models are backed by 100-night sleep trials and 10-year warranties.

Read on to learn more about how Eight Sleep mattresses are made and priced, and what customers, owners, and sleep testers have to say about the beds. We’ll also provide a detailed breakdown of Eight Sleep’s shipping, return, and warranty policies.

Sleep Rating

Durability
Good

Latex hybrids are typically among the most durable mattress types, and the Venus+ appears to be no exception; the expected lifespan is at least seven years.

Motion Isolation
Very Good

The Venus+ has a 4" comfort system with latex and foam layers that absorb and minimize motion transfer to a significant degree.

Conforming
Good

The Venus+ is considered 'Medium Soft' and offers deep, even body conforming that can be particularly beneficial for side sleepers.

Sex
Good

The Venus is fairly responsive, as is normal for hybrids, and should be sufficiently bouncy for most couples.

Temperature Neutrality
Very Good

A latex comfort layer and good airflow in the coil layer allow the Venus+ to sleep at a cool, comfortable temperature for most.

Off-gassing
Good

Off-gassing does not appear to be a major concern with the Venus+, but some light odors may be present when the mattress is unboxed.

Edge Support
Very Good

The Venus+ offers decent edge support, thanks in part to the thick coil layer, and minimal sinkage should occur around the perimeter.

Noise
Good

The Venus+ is not particularly noisy, but some squeaks and creaks may occur from time to time.

Though Eight Sleep offers four individual beds, three – the Saturn+, Jupiter+, and Mars+ – are all considered ‘Medium Firm’ (6.5). This firmness is optimal for sleepers who weigh at least 130 pounds, particularly back and stomach sleepers; it may be too firm for lighter people and side sleepers. The Venus+, with its ‘Medium Soft’ feel, is a better option for side sleepers and those weighing less than 130 pounds. This model conforms deeply to help align the spine and alleviate pressure points – but it may be too soft for people who weigh more than 230 pounds, as well as stomach sleepers.

Our testing process found Eight Sleep mattresses should also be great for you if…

  • You’re looking for a mattress with built-in sleep-tracking technology
  • You prefer beds with average thickness profiles
  • You and/or your sleep partner awaken easily due to movement or noise
  • You want to buy a mattress sold at a below-average price-point

Trial Period and Guarantee

Eight Sleep offers a 100-night sleep trial for all current mattresses.

  1. This sleep trial does not require a break-in period. Customers may return their mattress for a full refund at any point during the 100-night trial.
  2. In the event of a return, full refunds will be issued; Eight Sleep will cover all associated shipping and transportation costs and coordinate free mattress pickup from the customer’s residence.
  3. All returned mattresses are either recycled or donated to charity, depending on where the customer lives.
  4. The full 100-night sleep trial is extended to those who purchase the mattress directly from Eight Sleep on Amazon.com.

Warranty

Eight Sleep offers a 10-year warranty for all mattresses. Additionally, the Eight Smart Cover (technology layer) is backed by a separate one-year warranty:

  1. The 10-year mattress warranty is entirely nonprorated.
  2. Warranty coverage is contingent on proper foundational support. Per Eight Sleep: “The Products are covered by warranty only if they are used on 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, from the date of delivery onward to the date of the warranty claim without interruption; otherwise the warranty is void. Other placement (whether long or short term) of the Product, including but not limited to foundations of other description, a storage facility in any orientation, or use of a non-sufficient frame beneath the foundation, voids this warranty…A sufficient frame on which the foundation rests must provide sturdy support for both the Product and foundation and in the case of a queen or larger must have 5 or more legs including a center support.”
  3. If mattress repairs or replacements are warranted, owners must cover all associated shipping, transportation, and inspection costs.
  4. The technology layer warranty is also entirely nonprorated. It covers the technology layer for a period of up to one year if purchased in the U.S., or two years if purchased in Europe.
  5. Additionally, the fabric cover (not the technology layer) is covered against defects for up to two years.
  6. The warranty will cover the following defects:
    • Visible sagging or indentations in the sleep surface measuring one inch (1″) or deeper.
    • Physical flaws in the mattress that cause damage to foams and other materials despite proper use and handling.
    • Manufacturing flaws associated with aspects of the mattress cover, including seams and zippers.
  7. The warranty will not cover the following:
    • Sagging or indentations in the sleep surface that do not measure one inch (1″) or deeper, or normal increases in mattress softness that do not compromise the bed’s pressure-relieving abilities. These issues are considered standard wear and tear.
    • Repair or replacement requests that occur due to changes in the owner’s comfort preferences.
    • Burns, cuts, tears, stains, and other types of physical damage that occur due to physical abuse or neglect.
  8. This warranty is non-transferable. It is exclusively available to original owners who purchase their mattress from Eight Sleep or an authorized retailer. Those who buy or acquire their mattress from the original owner or a non-authorized retailer do not qualify for warranty coverage.

How Do Eight Sleep Mattresses Compare to Other Beds?

As any consumer does with a product they’re considering, our mattress assessments naturally involve comparing them with other similar products. Be it composition, firmness, or price, we think it’s important to see how Eight Sleep mattresses stack up to other beds.

Eight Sleep’s biggest advantage is the built-in sleep tracker; very few competing brands offer smart mattresses with integrated technology of this caliber. Beyond that, the all-foam Eight Sleep Beds (Saturn+ and Jupiter+) provide very good motion isolation and produce no noise when bearing weight; they also offer moderate conforming and a ‘Medium Firm’ feel that is most suitable for sleepers who weigh at least 130 pounds. Eight Sleep’s hybrid models (Mars+ and Venus+) also isolate motion fairly well, but not to the same extent. Advantages of these hybrids include great temperature neutrality and strong edge support. The Mars+, like the brand’s all-foam beds, is ‘Medium Firm’ and best for sleepers who weigh at least 130 pounds. The Venus+ is ‘Medium Soft’ and provides deep conforming that is most suitable for lighter individuals, as well as side sleepers.
