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.

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.

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.
