How it stands out

The Story

It seems every other day a new bed-in-a-box launches. Eight didn't start out selling mattresses. Their first product, the sleep tracker, launched in 2014 as an Indiegogo campaign. Their CEO was having issues with Restless Leg Syndrome (RLS) and was having trouble falling asleep. He often forgot to wear his tracking wristband so his data was always spotty so he wanted something consistent and that's when the sleep tracker was born. The campaign raised over $1.2 million dollars.

One year later they launched their website. Customers kept requesting for a mattress, so after analyzing millions of hours of sleep and trying every bed in the market, they launched their first smart mattress.

Technology

  • Sleep Tracking [read more="(Click to expand)" less="Read less"]By just lying down, the smart sensors monitor your heart rate, breathing rate, tosses and turns, breaks, and other factors to determine whether you are awake, in light sleep, REM, or deep sleep. It can also detect the temperature of the room and the bed. Every morning you are given a sleep score and you can analyze the data from the night before through various charts and timelines. You can also view weekly and monthly data.[/read]
  • AI-Powered Sleep Coach [read more="(Click to expand)" less="Read less"]This feature was launched due to customers asking, "well, how does this bed make me sleep better?" The coach collects your data to make recommendations on how to improve your sleep. It will also point out patterns you might not have noticed yourself (for example, if you slept worse this Tuesday rather than the past 3 Tuesdays). It benchmarks you against your own data as well as others within your state, age group, gender, and more.[/read]
  • Bed Warming [read more="(Click to expand)" less="Read less"]Each side of the bed has its own setting from 1-10. You can turn it on yourself, set a timer (e.g. have it shut off after 2 hours), or schedule it for later. The bed warming will automatically shut off after 10 hours if the user does not take any action.[/read]
  • Smart Alarm [read more="(Click to expand)" less="Read less"]Wakes you up during your lightest sleep cycle. You can choose a time frame that is up to 15 or 30 minutes before your designated wake time. You can also choose which days of the week this alarm activates and which relaxing sounds you would like to hear.[/read]
  • Alexa Integration [read more="(Click to expand)" less="Read less"]Ask Alexa how you slept last night or warm either side of the bed to your preferred setting. You can also shut off bed warming with Alexa as well.[/read]
  • Smart Home Integrations [read more="(Click to expand)" less="Read less"]Through IFTTT, you can have various devices "talk" to your Eight. For example, you can have Philips Hue lights turn on with your smart alarm in the morning. Then, once you shut the alarm, you can have WeMo Mr. Coffee brew a pot of caffeine for you.[/read]

Construction

Eight has three different comfort models: the Saturn+, Jupiter+, and Mars+. Each smart model includes technology. You can compare the three mattresses on their site here.

All of the mattresses are CertiPUR-US certified, which means that their foams meet rigorous standards for minimizing off-gassing. The mattresses are made without harmful chemicals such as formaldahyde, ozone depleters, heavy metals & flame retardants.

The Saturn+ Mattress

This mattress is 10 inches tall and includes one tech layer and three foam layers.

This is the firmest Eight model and therefore most suitable for back sleepers.

[read more="Read more" less="Read less"]

Layer One: Includes piezo sensors that cannot be felt through a sheet-like material.

Layer Two: 2" Responsive Foam for firm back & hip support.

Layer Three: 2" Transition Foam to minimize movement transference.

Layer Four: 6" Supportive Foam for max durability.

The Jupiter+ Mattress

This bed is ideal for side or stomach sleepers.

[read more="Read more" less="Read less"]

Layer One: Includes piezo sensors that cannot be felt through a sheet-like material.

Layer Two: 2" Reactive Foam which hugs like foam and reacts like latex.

Layer Three: 2" Contouring Memory Foam which provides ideal support for hips and back.

Layer Four: 2" Supportive Transition Foam to minimize movement transference. This is especially helpful if you have a partner that tosses and turns a lot.

The Mars+ Mattress

This mattress is 11 inches tall and includes one tech layer and four foam layers. Side sleepers will enjoy this bed. Due to the added coil support system, sleepers that weigh up to 300 pounds should opt for this bed. It also has additional airflow which is beneficial for hot sleepers.

Firmness

Each mattress has its own level of firmness. We rated each firmness on a scale of 1-10 with 10 being the firmest. You can compare the three mattresses on their site here.

Saturn+ is the firmest mattress available on their site. It has a 7 rating on the firmness scale.

Jupiter+ is described as medium firm. It has a rating of 6 on the firmness scale.

Mars+ is described as medium-soft firmness due to its coils in between the layers giving it a little extra bounce. It has a rating of 5 on the firmness scale.

Motion Transfer

This factor is especially important to couples who may have a partner who tosses and turns a lot.

The best model for this would be the Jupiter+ mattress. The Mars+ mattress has the same motion isolation layer as the Jupiter+ model, but due to the coils in between the layers, there is slightly more bounce.

Trial Period

You can try the mattress free for 100 Nights. All of their products have free shipping and returns. If you do not love your mattress, you can return it for free and the support team can coordinate a pickup. Eight does not resell used mattresses but can suggest disposal services or potentially places to donate your bed depending on your location.

Warranty

If your bed is defective (for example, it sinks in), then Eight will replace for free during the 10 year warranty. For the smart layer, it has a 1 year electronic warranty.
