Eight Sleep Smart Bed Review: Overview

The big sell with most online beds is convenience and value. With Eight, it’s more about the smart features than anything. Although this is not technically a smart mattress, Eight does have an interesting concept as far as their overall value proposition is concerned.

As with many of our reviews, we simply cannot fit everything into a concise video. As such, we’ve written a full post below with even more details.

Eight Sleep Policies

After purchasing your Eight Sleep Smart Bed, it will ship completely free, straight to your doorstep. It will be compressed in a plastic wrapping and stuffed inside a cardboard box that’s around four feet tall. You’ll need to bring the box inside. We recommend you unwrap the box in the room you intend on using the mattress in. Remember to give the mattress time to inflate and off-gas after unwrapping it (about 24-48 hours).

From the day of delivery, you’ll have 100 nights to test it out. If within this 100-night trial period you decide this isn’t the best bed for you, then just contact the company for a full refund. They do ask you to sleep on the bed for at least 30 nights before asking for a return because that is about how long it takes on average for the body to adjust to a new bed. If you make a return, they’ll send someone to come remove the mattress for you, all free of charge.

If you keep your Eight Sleep mattress, it will be covered under a 10-year warranty, much like other mainstream bed-in-a-box companies like Casper or Purple.

How Much Does The Smart Bed Cost?

With the Eight Sleep mattress being pretty much a basic all-foam bed, what you’re really paying for is the smart sleep tracking cover. We’d still put it in the average category, price-wise. It’s priced similarly with Brooklyn Bedding Signature or Leesa. Here’s a pricing breakdown per size:

King / Cal King$1,295

The Smart Bed Has A Simple Foam Design

The Eight Sleep Jupiter is a 10” all-foam bed with a slight memory foam feel. Let’s really break it down into its construction, though.

The Eight Sleep Jupiter has four layers of foam to it. The base layer is 4” supportive polyurethane foam, then 2” of transitional poly foam, followed by 2” of memory foam, and then finally topped off with 2” of synthetic latex foam, which contours like poly foam, but is responsive like regular latex foam. To be clear, Eight Sleep is not a latex mattress—it just has a layer that acts somewhat like latex.

What’s inside the Eight Sleep Jupiter mattress

All of the foams used in Eight Sleep mattresses are CertiPUR-US certified, meaning they meet the standards for content, emissions, and durability, and are analyzed by independent, accredited testing laboratories. Basically, they’re very safe for you to sleep on.

We think the cover is the best part about this bed. Besides its polyester cover, which encases the foam, every Eight Sleep mattress comes with a sleep tracking cover. Its features include tracking your sleep and breathing patterns, warming up the bed, and communicating with other smart technologies in the home.

To learn more about the smart cover, go to Because this cover is an electronic device, you cannot wash it. Just so you know, that smart cover will work on basically any 10″ mattress. They sell it separately on their website, but it’s pretty pricey.

Firmness Ratings For The Smart Bed

When we received our Jupiter mattress, Eight Sleep offered a feature that let you split the bed down the middle to have two different firmness levels—one per side. Say you are a side sleeper, but your partner is a stomach sleeper, you could customize the mattress so that you had a softer side and they had a firmer side. Unfortunately, Eight Sleep does not offer the split firmness option anymore. Not a huge deal. Clearly, it wasn’t popular or they would have continued the program.

After some research, our educated guess is that the current Jupiter model has a medium to medium-firm firmness level.

Because the Eight Sleep Jupiter uses both memory foam and responsive foams in their top layers, it has a slight memory foam feel that’s comparable to that of Lull. When you lay down on the Jupiter, you’ll sink into the bed a bit and feel it contouring to your body, but because of the responsive top layer, you’ll most likely never feel “stuck in the mud.”

Latex is known for being very responsive, while memory foam is usually slow to respond after pressure is removed, and the effect is a more neutral feeling bed.

Which Sleeping Positions Can The Smart Bed Handle?

Back and stomach sleepers want to keep their spines in neutral alignment in order to avoid back strain and pain. To do this, they’ll need a firm mattress that will support their hips and shoulders instead of letting them sink into the bed too much, which causes the spine to arch.

It will work for back sleepers (and stomach sleepers)

If you try the Eight Sleep and find that your back is curving because you’re sinking into the bed too much while sleeping on your back or stomach, this isn’t the best bed for you. Remember that they do offer a trial period with free returns. Don’t be afraid to take advantage of that.

Side sleepers should be good as well

Side sleepers typically need a softer mattress that will accomodate for the curve of their hips and shoulders when they’re on their side, instead of a firm surface that will push against them. If your Eight Sleep mattress has you waking up in the middle of the night with a dead arm, it’s not the best mattress for you.

Is Eight Sleep Good For Heavy Individuals?

No. Heavier individuals typically need a coil or spring mattress to support their weight properly. They might also wear out an all-foam mattress sooner than they’d like, as they’re usually not durable enough to carry more weight every night in the long run.

What About Other Body Types?

This bed will be fine for super petite individuals, but it might feel a little bit firmer. The lighter people are, the less pressure they exert on a mattress’s surface, so they lay more on top of the bed instead of sinking down in the bed. Because of this, beds tend to be firmer feeling for them, so petite people should stick to sleeping on their backs and stomachs on the Eight Sleep.

Just fine for individuals weighing under 225 lb

As for kids and teens, this bed is also fine for them, but you might want to steal the sleep tracking cover for yourself, especially since you can connect it so that your coffee will start brewing when your alarm goes off.

Does The Smart Bed Sleep Hot?

Only if you want it to! The smart cover has warming technology that you can set per side. It’s on a scale of one to 10, and it gets pretty warm. There’s also a timer you can set, so you can have your bed warm up all on its own before you even crawl into it. Say you normally go to bed around 11 pm every night, set your sleep cover to warm up around 10:45 pm. We think this is pretty cool.

What the Eight Sleep does not have is any cooling technology. If that’s something you’re interested in, check out our Best Beds for Hot Sleepers list.

Eight Sleep Mattress Review: Last Words

Our thoughts are that you would mostly purchase this mattress for its smart cover, as the mattress itself is pretty basic. It’s a 10”, all-foam mattress, much like Tuft & Needle or Morphiis. We mostly think this mattress will appeal to those who are interested in tracking their sleep, warming their bed, and are excited about pairing it with other smart technologies in their home.

What Makes Eight Sleep Different?

On the mattress side, not much. The bed has a fairly standard foam construction. It’s comfortable, but it’s not out-of-this-world unique, which is clearly what they were going for since they want to appeal to as many people as possible. Eight Sleep is more about the technology in their special cover. We think it’s neat that you have the heating feature, alarm, and sleeping tracking, but we simply don’t know how many consumers are willing to pay for this stuff.

How did we get this bed?

They sent it to us to try out. But as always, we are in no way obligated to give good or bad reviews about it. We here at the Slumber Yard always do our own research on every product we test to come up with our own opinions. We are also looking into testing their new Jupiter model, as the one we have is no longer available.

I thought this was a smart mattress, not a smart cover?

You thought wrong. We thought wrong initially as well. This is a normal mattress with a smart cover.

Does Eight work with IFTTT?

Yes. And through IFTTT, Eight then ends up working with dozens of other apps and companies.

Does the cover work with Alexa?

Yes. It can pair with Alexa to trigger several different smart commands. Not sure how practical this is, but you can ask Alexa how you slept the night prior.

Can I find Eight Sleep beds at any stores?

So far, it looks like Eight Sleep is sticking to the online-only model. We've seen other brands including Purple, Tuft & Needle, Casper, and others start to sell in-store, but still, the vast majority of brands stick to selling online only.

What is the Eight Sleep Pod?

It's a new mattress concept from the company that dynamically heats/cools your bed to (hopefully) keep it at the perfect temperature for you during the night. It looks like a combination of their existing mattress and a BedJet, which is a heating/cooling system that was featured on the show Shark Tank.

What other sleep products does Eight Sleep sell?

They have blue light blocking glasses (for scrolling through Instagram before bed), a mattress foundation, pillows, and a mattress protector. No adjustable base yet or proprietary sheets.

Did they change the name of this bed?

Sort of. It looks like Eight Sleep shook up their mattress lineup in early 2019. They used to offer a number of mattress models, including one with dual firmness levels. Now, however, they've just gone with two mattresses: The Smart Bed and The Pod. Probably a smart move, considering their entire brand is built around the "smart mattress" concept.
