Product Description

Comfort meets technology in the most innovative mattress

Looking for a better night's sleep? Get the Eight Smart Mattress and have the full smart sleep experience: a highly comfortable mattress plus the technology layer to help you track and improve your sleep. There’s nothing else like it. True innovation for better Zzz’s.

The data-driven Eight Smart Mattress is designed to allow users to sleep smarter. Integrated with sensors and a corresponding app, the Smart Mattress tracks room temperature, tosses and turns, sleep patterns, deep and light sleep, and more. Features like the in-app sleep meditation feature hosted by Simple Habit gives users the option to fall asleep or wake up via meditation and cultivate mindfulness.

Eight uses innovative technology, detailed design, and proven science with real time data collected from their users to personalize and improve your sleep bringing their direct to consumer model to the forefront from its competitors.

Highest comfort and support for every sleeper

Four layers of total bliss + one layer of technology. Forms to you, but bounces back. Supportive with no pressure. Cozy, but not too warm or cool.

Composition from top to bottom:

  • Technology layer: Proprietary technology to track sleep, warm up the bed,and connect with other smart home devices.
  • 2” Reactive foam: A unique foam that bounces like latex but feels like foam. Designed to be comfortable and stay cool.
  • 2” Contouring memory foam: All the benefits of memory foam: contours to your body while providing pressure relief.
  • 2” Supportive transition foam: Additional comfort and consistent weight distribution to support all body types.
  • 4” High density support foam: A durable foundation that is highly breathable and adds just the right firmness.

The Eight Smart Mattress offers dynamic support and contouring comfort without sacrificing breathability or resilience.

It features a unique cell structure that bounces back to its original shape every time, while delivering buoyant, responsive comfort with excellent pressure point relief.

What makes it different from all other mattresses?

Born out of co-founder and CEO Matteo Franceschetti's own battle with sleeplessness and insomnia, the Eight Smart Mattress is designed so users can learn from their sleep and gain insight about how to get their best night's sleep.

Eight’s team designed the smart mattress by studying over 1.8 million hours of sleep data that have been tracked through the company’s first product — the Eight Sleep Tracker— which by the end of 2016 was already tracking mroe than 12,000 people across 67 countries.

The Eight Smart Mattress includes features that improve the sleep experience, like automatic temperature control for each side of the bed, and connectivity with other smart home devices like thermostats, lights and coffee machines. The mattress contains multiple sensors to track sleep times, deep and light sleep, breathing rate, and measure toss and turns, bed temperature, and room temperature. Over time, the Eight Smart Mattress uses machine learning to build patterns on sleep behaviors, and displays suggestions for sleep improvement in its mobile app. It can also share this data with health tracking apps like Apple’s Health and Google’s Fit.
