Our Full Eight Sleep Saturn+ Review 2018

The latest thing in bed-in-a-box mattresses is having a smart mattress. Eight Sleep is one of the leaders in smart mattress technology as they are on a mission to get everyone sleeping at their best. To do this, mattresses like the Saturn come with a sleep tracker cover that monitors over 15 factors during your sleep that can unravel your sleeping habits so you can improve them. Some of the things tracked include your heart and respiratory rate, temperature, and how long you were in deep sleep. This information is available daily on your smart phone.

You can also use your phone to do things like change the temperature of the bed using your phone and smart app. If you have other smart home features like Alexa, Philips Hue, or Nest you can connect with those as well. This would allow you to have your lights shut off when you start to fall asleep or get your coffee brewing on its own right before you wake up! It really doesn’t get any better than that! For this Eight Sleep Saturn+ review, I tried to take a look at how the budget differences of the Saturn made it different than the others. I didn’t come up with much. The mattress is still comfortable and the smart tracking is next level. If you’re interested in tracking all of the details of how you sleep, this mattress offers what you need.


Eight Sleep Saturn Cost and Mattress Models

The Eight Sleep Saturn cost provides a smart mattress at an amazing price.

It’s highly unlikely that you’d find a better price on a smart mattress than the Saturn+ offered by Eight Sleep. Beds range from Full all the way to California King with no option over $900. In fact, you can get the California King for under $800. As for the Full, those start around $550. It’s also worth mentioning that you can actually purchase the Saturn and the other smart mattresses without the smart cover. This obviously would make them just like any other foam mattress and wouldn’t track your sleep, but it would lower the price some. I cannot personally speak to how the bed feels without the smart cover since for this Eight Sleep Saturn review we used the cover and the smart features.

That said, even if you need to save money, the Saturn presents you with a great opportunity to get a smart mattress at an amazing deal.

Size Dimensions Price
Full 54” x 75” x 10” $549
Queen 60” x 80” x 10” $649
King 76” x 80” x 10” $799
California King 72” x 84” x 10” $799

It’s hard to imagine anyone finding a better deal for a smart mattress than you’ll find with the Saturn+.

Remember, you can try this mattress risk-free for 100 nights.


Composition: How it’s Made

Three layers and a smart cover provide the keys to excellent sleep.

The main difference between the Saturn+ and the other two smart mattresses that Eight Sleep makes is that the better price means you lose a layer. Still, this 10” mattress offers three layers of high density, comfortable foam along with a smart tracking cover that can do everything from set your bed temperature to connect with other smart features throughout your home.

When it comes to the mattress itself your three layers start with 2” of responsive foam. This is the top layer of all of the Eight Sleep smart mattresses. It provides the feel and bounce of latex even though its standard foam. This also means that it will be both cool and comfortable, making it a nice choice for those looking for the best cooling mattresses. Next up is 2” of transition foam. This works as the buffer between the foundation base and the top layer of foam. One of the main functions is to provide additional comfort. Finally, the bottom 6” are made up of the support base foam. This layer is needed to create a foundation for the mattress.

How Comfortable is an Eight Sleep Saturn+ Mattress?

The Saturn offers comfort, support, and the right amount of breathability to remain cool.

When doing our Eight Sleep Saturn+ review, we look at a lot of things to determine how comfortable the mattress is. As there are less layers, it was important to ensure that comfort would not be sacrificed. I’m pleased to report that it’s not. It’s equally as comfortable as other models. It sleeps cool and provides a stable, supportive place to lay your head. Whether you sleep on your back, stomach, or side, the Saturn should be able to provide the rest you need. If it doesn’t the daily sleep tracker supports should help you pinpoint the issue blocking your sleep so it can be rectified and you can get the rest you need!

  • Firmness: The Saturn is about a six on the firmness scale. This means you’ll have a mattress that will support you firmly, but will be soft enough to be comfortable. Many beds shoot for this level of firmness because it will appeal to more people. It also means that the Saturn is going to be suitable for people of most sleep positions.
  • Sinkage: There wasn’t much sinkage to report during the Eight Sleep Saturn+ review period. Naturally, like most foam beds, the edge support is a little less consistent, but the rest of the bed allows you to be nestled comfortably without actually sinking to the point where movement is hindered.
  • Motion Transfer: Three thick layers of foam are here to absorb most of the vibrations that occur with movement. This means that if you get up in the middle of the night, it’s unlikely that your partner will feel it. This allows for you to sleep easier not feeling every toss and turn of the person next to you. All in all, it’s a good mattress for couples.

“Mattress Magic”: Is the Eight Sleep Saturn+ a Good Bed for Sex?

You’ll get plenty of bounce thanks to the responsive foam top layer.

Remember earlier when I mentioned the top layer of the Saturn was responsive foam? Well, these two inches are going to add a remarkable amount of bounce to your mattress. In turn, this will make the mattress easier to move on, which will make having sex easier and more enjoyable. Sure, this isn’t the most important factor when it comes to picking out your new mattress, but knowing that you can experience intimacy in a comfortable setting doesn’t hurt. So, we’d definitely say this is a good mattress for sex.
