Off Gassing

The very first thing to do with your new Eight mattress is take it out of the box and get it set up. It should show up right at your door and in a fairly compact box, for a mattress anyway. Getting it to where it needs to go may take two sets of hands. It is about 75 lbs and a little awkward to maneuver if you’re on your own. Once you get it to where you’ll be sleeping it should only take a few minutes to get it out of the box and take it out of the plastic and come to life.

The unique thing about the Eight is that there is a separate box with just the smart cover. This will need to be put over the mattress once it is fully formed. To operate the cover all you need to do is download the Eight App and you will have full access to all your sleeping metrics.

During the unboxing process you will notice a bit of off gassing but it should be very minimal. With most boxed mattresses there will be a little bit of smell once it is allowed to unroll and take shape, but this one is made in the US which helps tremendously with cutting down on any noxious odors. It should be fine within a few hours but if you are more sensitive to certain smells letting it breath up to 12 hours would probably be a good idea.

When setting up your new mattress it will need a foundation that provides a flat, even surface that will support the weight of the mattress as well as the sleepers. It also will need to be the right height for you as well as be aesthetically appealing. The Eight mattress would work great on a box spring with or without a frame, an adjustable base, a platform bed or slatted bed. To find a foundation that would work for you check out our frames & bases reviews.

The Eight Jupiter  mattress uses a four foam layers to create an ideal feel. The top layer is a reactive foam that is suppose to have the bounce and response of latex. This is a comfort layer that also is meant to aide in keeping the mattress from getting too warm. Under the top layer is a layer of memory foam to create a more conforming layer to help contour to your body and allow for pressure relief and normalized sleep patterns.

This 10″ mattress should fall around a 6 on a firmness scale of 1 being the softest and 10 being the firmest. It will work well for back sleepers, allowing enough support and enough sink to alleviate pressure and make a sleep surface that cradles your lumbar and shoulders. The Bear mattress would work well for a side sleeper too, really allowing for your shoulder and hip and to sink into a nice combination of conforming and springy foam. This mattress should even be good for stomach sleepers, and provide the necessary support throughout the night. This mattress should be comfortable for the majority of people out there.

If you are sleeping on the mattress with the sleep tracker the feel of this mattress or any other will be slightly altered. This removable cover does add its own feel to the mattress and the sleep tracking technology may not appeal to all people. Unless tracking your sleep is very important to you the added “smart” layer may not be for you.


Motion Transfer

Between all the comfort foams as well as the dense base foam this mattress will absorb most vibrations and make for very minimal to no motion transfer to be felt. The Eight mattress is great for anyone who shares a bed because of this, there will be little disturbance when getting in and out of bed.


Sleeps Cool

The Eight mattresses may be less focused on staying cool than many other mattresses which may mean it may sleep warmer. This mattress doesn’t have any added gels or cooling properties added to the top layers to prevent over heating. It also has an option to warm the bed through its smart cover but not an option to cool it. The top layer is meant to feel more like a latex and by having a more responsive layer on top this may help with some heat dissipation. However, overall this mattress may not be ideal for someone who sleeps on the warmer side.


Edge Support

The edge support on the Eight mattress should feel fairly stable and create an edge to edge usable sleep surface. The transition and base foam provide the necessary support to give the entire mattress a solid foundation, including the edges as well. Sleeping on this mattress you should feel a consistent feel across the entire top of the bed. As far as sitting on the edge goes, there is a little less support, sitting on it may be less ideal and not feel very solid.



The Purple mattress comes in at $999 for a Queen size. With this price free shipping is also included. As well as a 100 night sleep sleep trial and 10 year warranty. This mattress is unlike many others out there and the price point is very competitive right under the $1000 mark. Even the King size mattress comes under the $2000 mark if you wanted to get something larger for your sleeping situation.

Next is a  2″ layer of Contouring Memory Foam which is great for pressure relief and weight distribution as well a great comfort layer.

The middle layer is 2″ of 1.8lb density Transition Foam that provides support as well as help create a tranasition between the top foams and the base foam.

The foundation is made of 4″ of 1.8lb density support base foam. This provides the support of the mattress and creates durability as well as stability for the foams on top.
