‘Smart mattress’ is a loose term referring to any mattress model with sensor technology designed to monitor the sleep patterns and routines of its owner(s). Today’s smart mattresses can track how long a person sleeps and the duration of their REM cycles, as well as physiological factors like body temperature, heart rate, and breathing. Other functions of a smart mattress may include alarms, adjustable climate control, and internet connectivity. Additionally, some smart airbeds enable owners to adjust the firmness settings of their sleep surface using remote controls.
In today’s market, many smart mattresses utilize app technology that allows owners to adjust controls using their phone, tablet, or other compatible devices. Smart mattresses are somewhat rare, and tend to be much more expensive than the average mattress model. Although some smart mattresses are priced below $1,000, the majority cost more than $2,500 in the standard Queen size. In addition to mattresses, some removable mattress toppers are also equipped with smart technology.
Read on to learn more about how smart mattresses are constructed and how they function, as well as some of the most popular models available today.
What Can Smart Mattresses Do?
Smart mattresses offer some — if not all — of the following functions:
Sleep Tracking: Smart mattresses feature sensors that connect to hubs via wireless technology or electrical outlets; they do not require sleepers to attach equipment to their bodies. Using sensors placed throughout the cover, smart mattresses are designed to monitor the following data points:
- The time you physically get into bed.
- The time you fall asleep.
- The amount of time required to fall asleep (i.e., 15 minutes after getting into bed).
- The time you wake up.
- The time you physically get out of bed.
- The ratio of deep sleep to light sleep you experience during the night. For example, the monitor might read ‘45% deep sleep/55% light sleep’.
- Number of sleep breaks of interruptions when you are awake for a significant amount of time after initially falling asleep.
- Your sleep position(s) during the night.
- The number of times you toss and turn throughout the night.
Body and Environmental Monitoring: Using the same sensors for sleep tracking, smart mattresses can monitor these factors:
- Your heart rate.
- Your breathing cycle.
- Your body temperature.
- The temperature of the bed surface.
- The room temperature.
- The amount of light in the bedroom.
Sleep Scoring: Using the sleep tracking data listed above, and taking body and environmental factors into account, some smart mattresses create ‘sleep scores’ for users based on the quality and duration of their sleep. Some programs feature functions that allow sleepers to set goals based on their previous sleep scores.
Mattress Adjustment: More advanced smart models — including airbeds — allow sleepers to customize certain mattress settings, such as:
- Firmness: Adjustable controls in smart airbeds allow sleepers to increase or decrease the amount of air in each individual chamber, resulting in surfaces that are less or more firm than before.
- Temperature Control: Customizable climate control is often included, and in some cases allows owners to set different temperatures for each side of the bed to accommodate sleep partners with different preferences. In some cases, up to 30 minutes may be needed for temperature changes to take effect.
- Bed Position: The smart technology may connect to the bed base, allowing owners to adjust the head, foot, and midsections of the bed. Elevating the head of the bed while keeping the rest of the surface flat can be beneficial for those who snore. Elevating the legs and/or midsection can also aid people with lower back pain or leg cramps.
- Environmental Settings: A common term associated with smart technology is the Internet of Things, or IoT. This refers to systems that link various appliances throughout the house — such as lighting fixtures, thermostats, coffee makers, and televisions — using Wi-Fi connections. Some smart mattresses offer IoT connectivity, and may also be programmed to intelligent personal assistance programs like Amazon Alexa. This allows owners to adjust various settings in their bedroom, such as lighting and temperature, and also adjust mattress qualities like firmness and bed temperature using intelligent personal assistance programs.
Other Functions: In addition to those listed above, smart mattress technology often features the following applications:
- Alarms with customizable ringtones.
- Playable music, as well as white noise.
- Guided meditation programs designed to help you sleep better.
- Connectivity to fitness trackers and other devices that monitor your activities throughout the day. Some smart mattress apps include energy input tracking that monitors activities that may affect your sleep, such as exercising or consuming caffeinated beverages.
Which Smart Mattresses Are Currently Available?
Now that we have discussed smart mattress functionality and some common features of these products, let’s look at smart models from three leading mattress brands and how they compare with one another.
Eight Sleep: Eight Sleep offers three smart mattresses as part of its ‘Smart Collection.’ The mattresses come with a removable Sleep Tracker cover made of polyester with a built-in tracker that connects to a smart app.
- The Saturn+ features a comfort system with a top layer of memory foam and a bottom layer of polyfoam. The support core is constructed from high-density polyfoam.
- The Jupiter+ has a comfort system with three primary components: a top layer of ‘reactive’ memory foam, a middle layer of ‘contouring’ memory foam, and a bottom layer of polyfoam. The support core is made of high-density polyfoam.
- The Mars+, unlike the other two, is a hybrid mattress. The comfort layer features two layers of memory foam, followed by a bottom layer of polyfoam. The support core is constructed with pocketed coils and a base layer of high-density polyfoam.
Pros of the Eight Sleep Smart Collection include the following:
- The three mattresses in Eight Sleep’s Smart Collection are relatively low-priced compared to other smart models.
- Eight Sleep’s 100-night sleep trial does not include a mandatory break-in period, allowing customers to return the mattress at any time before 100 nights have elapsed. Additionally, Eight Sleep covers shipping and handling costs for mattress returns.
Some cons associated with these mattresses include the following:
- All three mattresses come in one, non-adjustable firmness setting: 6.5, or Medium Firm. Sleepers who prefer mattresses that are more or less firm may not feel comfortable on these models.
- Eight Sleep has been in business for less than four years (as of December 2017), and the long-term performance of the Smart Collection mattresses has not yet been evaluated.
The table below breaks down each Smart Collection mattress in terms of height, firmness, layer components, and other specifications.

ReST: Short for Responsive Sleep Technology, LLC, ReST offers the ReST Bed, a smart airbed.
- The comfort layer of the mattress is made with two layers of gel memory foam.
- The support core features a top layer of high-resilience polyfoam, followed by foam-encased air chambers that target five specific areas of the body: head, shoulders, lower back, hips, and legs. Using the ReST smart app, the mattress can be programmed to three different settings:
- Automatic: The mattress continually adjusts to the sleeper’s firmness preferences throughout the night.
- Auto Position: The sleeper customizes firmness settings for different sleep positions — such as back, side, and stomach — and the mattress will respond to position changes during the night.
- Manual: Sleepers can adjust firmness settings for each of the five target areas of the body at any time.
- The cover is made of 100% Lycra® spandex, and features a built-in sleep tracker with sensors that monitor more than 2,000 different pressure-point areas. The sensors do not affect the feel of the cover to any significant degree. Sleep data is accessible via the ReST Bed app.
- The Twin XL size is a one-sided model with one air hose. All other sizes are two-sided, and come with two air hoses for dual adjustment.
Pros of ReST and the ReST Bed include:
- Targeted firmness settings can alleviate pressure, aches, and pains in different areas of the body, making this bed a good choice for physically active people or those with chronic pain isolated to specific bodily regions.
- Compared to other smart mattresses, ReST Beds are widely available; in addition to purchasing them online, shoppers can find models at more than 40 brick-and-mortar stores across the country.
Some cons associated with ReST and the ReST Bed include:
- The ReST Bed is fairly expensive. Prices range from $2,799 for a Twin XL to $4,599 for a King or California King. Split King and California King mattress models cost nearly $5,600. Furthermore, all mattress deliveries — which include in-home setup — incur an additional charge of $199.
- ReST was founded in 2013, and performance data for the ReST Bed does not extend beyond four years; long-term durability may be questionable.

Sleep Number: Sleep Number offers three smart mattresses sold under the ‘360 Smart Beds’ collection. These models come equipped with two adjustable air chambers in the support core and SleepIQ sleep-tracking app technology.
- The p6 has a polyfoam comfort layer and a cover made of polyester and rayon.
- The i7 has a gel memory foam comfort layer and a cover made of polyester and polypropylene.
- The i10 is a reversible model with a memory foam comfort layer on one side and a polyfoam comfort layer on the other. The cover is made of polyester and polypropylene.
These mattresses may be purchased alone or with an adjustable FlexFit base. There are three options for the Flexfit, all of which carry a different price-point:
- The FlexFit 1 allows sleepers to adjust the angle of the head only. It also features a light beneath the base for better visibility at night. This base costs $1,199 on top of the mattress price.
- The FlexFit 2 allows sleepers to adjust the angles of both the head and foot of the mattress, and also features a light beneath the bed. This base costs $1,799 on top of the mattress price.
- The FlexFit 3 features head and foot angle adjustment, as well as the light beneath the bed and a foot-warming function. This base costs $2,499 on top of the mattress price.
In addition to the three ‘360 Smart Bed’ mattress models, four of the brand’s five other mattresses come equipped with SleepIQ technology; the fifth can be customized with SleepIQ for an additional $149. They can also order a FlexFit base with their mattress. Please note that, for these models, the FlexFit 2 costs $1,599 and the FlexFit 3 costs $2,199; the FlexFit 1 has the same price-point. Like the models mentioned above, the following airbeds are all designed with two adjustable air chambers.
- The c2 does not have a comfort layer; its cover is made of rayon and polypropylene. This is the only current Sleep Number model that does not come equipped with SleepIQ technology.
- The c4 has a polyfoam comfort layer and a cover made of polyester and polypropylene.
- The p5 has a polyfoam comfort layer and a cover made of polyester and rayon.
- The i8 has a polyfoam comfort layer and a cover made of polyester and polypropylene.

Pros of Sleep Number mattresses include the following:
- Sleep Number mattresses can be easily repaired at home, resulting in low maintenance costs and above-average longevity compared to other airbeds.
- Sleep Number mattresses are widely available. In addition to the brand’s website, customers can choose from more than 550 brick-and-mortar stores nationwide.
Cons of Sleep Number mattresses include the following:
- Sleep Number mattresses have price-points that are well above-average, even compared to other airbeds (which are typically quite expensive). Customers should expect to spend at least $2,200 for an airbed with SleepIQ smart technology and the adjustable FlexFit base.
- Sleep Number offers a 25-year warranty, but only two years of the warranty are nonprorated. The remaining 23 years are prorated, and costs increase with each year of ownership, making repairs or replacements fairly expensive for owners who have used their mattress for more than two years.

Sleep Trials and Warranties
Because smart mattresses represent such a significant financial investment for most shoppers, it may be beneficial to take advantage of sleep trials offered by brands that manufacture these beds.
Here’s how sleep trials work: mattress brands allow purchasers to test out their new model for a fixed number of nights. If the customer is not satisfied before the sleep trial ends, then he or she can return and/or exchange the mattress for a full or partial refund. Some sleep trials require customers to test out their mattress for a certain length of the sleep trial before they will be eligible to return or exchange it. Additionally, the customer may be responsible for some extra charges associated with returns or exchanges.
Warranties can provide extra product security for a smart mattress. However, the sleep-tracking technology components of a smart mattress may or may not be covered under the product warranty.
The sleep trial and warranty policies of Eight Sleep, ReST, and Sleep Number are outlined below.
|Brand||Eight Sleep||ReST||Sleep Number|
|Sleep Trial Length||100 nights||90 nights||100 nights|
|Required Break-in Period||None||None||30 nights|
|Extra Fees for Returns?||None||None||Yes|
