Eight Sleep Mars + Mattress Technology Details

The Mars+ is an 11” thick mattress, combining the following layers:

The top-most layer of Mars+ is a 2” Reactive Foam. This surface adds subtle bounce and a quick response feel, preventing the “sink-in” issue particular to foam. The Reactive Foam layer further allows freedom of movement, especially helpful if you frequently change your positions while sleeping. The small holes in this structure keep the surface cool, aiding in temperature regulation.

The 2” thick Comfort Transition grants smooth transition from the upper foamy surface to the lower coiled layer. This Transition layer construction offers exceptional weight distribution, properly cradling your body curves.

The 4” Sleeved Coils layer of Mars+ is surrounded by Polyurethane Foam. This combination together delivers adequate bounce and support to decrease motion transfer, making Mars+ ideal for couples or people with pets. The spaces available between the coils assist in airflow and restrict heat retention while you are asleep.

The base is a 3” Support Foam. This high-density layer serves as a strong foundational support, adding to the durability and making Mars+ a long-lasting mattress.

Smart Technology Details:

If you are looking for a wholesome and luxurious sleep experience, the smart cover layer may be a valuable addition. Easily integrated with your smart home system, the Eight Sleep app offers a wide range of features to improve your sleep. It is effortless and you need no wearable gadgets to avail the smart technology.

The exceptional sensing capabilities of the sensor ensure the temperature of your mattress is appropriately regulated so you can sleep cool while you slumber. The sensor detects your rest hours and movements at night, providing you a detailed report with tips on how to sleep better. If you sleep with a partner, Eight Sleep offers two sensors on each side. The specialized alarm system wakes you up at the best time, per your sleep schedule, ensuring you get the rest you need. Thus, with Eight Sleep smart technology, you can enjoy a better deep sleep and become more aware of your lifestyle practices.

This is a universal comfort of 5 on the firmness scale for perfect medium soft. The pocket coil and poly foam support system provides a comfortable support, while keeping movement transfer to a minimum. This means no waking up your partner! Leave sleepare and read full review

Real Mattress Review - Ross Paumen

March 19, 2018
Eight Hybrid Mattress is a great medium option for those of you who sleep in multiple positions. The mattress slept cool and with the direct to consumer pricing they also are a good value. I like the floating on top feeling this provides vs a sinking/stuck feeling. Its a solid option and the tracker is awesome! Leave sleepare and read full review

The Sleep Sherpa - Ben Trapskin

February 21, 2018
a great way to get some objective data on how you sleep. Once it is setup, it is effortless. While the mattress itself should appeal to most sleepers, there isnt a one size fits all mattress. You can certainly find softer and firmer mattresses but if you are looking to upgrade to a memory foam mattress and are enticed by the idea of sleep tracking, this is an excellent choice.

feel of the mattress and think the technology is really awesome. My only caveat is that the sleep tracker itself changes the feel of the mattress and makes it a little bit less comfortable than it would be without the tracker. Leave sleepare and read full review

Good Bed - Michael Magnuson

Sleep Tracker topper adds a technology layer that tracks personal sleep patterns and bedroom environment data. The tracker connects to the Eight app which provides feedback to users on each night of sleep, and allows for effortless integration with other smart products to regulate bed temperature, lights, door locks, and more, in real time.
