I’m always happy to test smart beds like the ReST as the fillable air chambers and programmable smartphone app give me quite a lot to dive into. With that in mind, let’s have some fun with the ReST Smart Bed.
So just how smart do you have to be to review a smart bed? I may have struggled with high school physics, but I can definitely put the ReST to the test. By the end of this text, you should know all about this smart bed’s construction and customization features.
You can read my full review of the ReST bed below. If you only have time for a quick run-through, you can click here to head to the summary!
ReST Smart Bed Brand Snapshot
The ReST bed makes no bones about its preferred audience: This is a bed created for athletes and people with medical concerns who need a customizable sleep experience. The “smart” customizable remote control system lets you control the bed’s air chamber flow, which creates some exciting sleep opportunities.
The ReST brand only sells one product — the adjustable mattress and the flat foundation. The mattress is generally compatible with all adjustable bases. The company also states on its website that its foundation is industry standard size. Because it has no sister products in the product line, we will compare it to its rivals the Sleep Number i10 and Saatva Solaire to give you a better perspective of its performance. We’ll start with a description of the materials in the ReST and move on to its performance after that.
What Exactly are You ReSTing on?
The mechanics of a smart bed work best when paired with quality materials, Let’s take a look at what’s inside the ReST before we get into how it works.
Cover – The thin, breathable cover is made of a stretchy performance cooling fabric that emulates athletic clothing. It doesn’t really get in the way of the feel of the mattress, and it is fully removable and machine washable.
Comfort – The comfort layer is comprised of a 3″ layer of gel-infused memory foam, which allows for plenty of sinkage and deep body-contouring. Memory foam is known to absorb and trap heat, so the gel infusion works to keep the layer cool.
Transition – Up next, you’ll land on a transitional layer of 1” of poly foam with a quick response to pressure. This keeps the sleeper from sinking too far into the support layer. because the air chambers in the support layer are what give the ReST its customizable firmness settings.
Support – The air chambers in this layer are what inflate or deflate according to the firmness parameters the sleeper sets. The ReST mattress has two sets of these air chambers, one on either side of the bed. This means partners can set their own levels from soft to firm with the ReST smartphone app. The support layer also has its own pressure map for each side of the bed, providing a readout of pressure points to the ReST app in real time.
Edge Support / Base – A thick layer of high density poly foam surrounds the air chambers in the support layer. The firm boundary helps the ReST keep its edge support even if the air chambers are set to a soft firmness level. This poly foam also serves as the base of the mattress, providing shape and durability.
Thoughts: Back, side, and combo sleepers should be able to find a comfortable firmness level, and partners can independently customize. The soft top layer may be a bit too soft for strict stomach sleepers. Partners can use the entire mattress thanks to the great edge support.
How Firm is the ReST?
Now that we know what the ReST is made of, let’s see how those materials contribute to the feel of the mattress.
The exact feel of the mattress depends on the individual. Body shape, size, and weight all make a difference. With this in mind, I tested the ReST alongside coworkers with different body types. We averaged our experiences together to land on the score you see below.
We rate firmness on a scale of 1 to 10 with 10 being the firmest and 6.5 representing the industry standard for medium firm. The ReST bed can adjust its firmness level independently in five different zones on the bed — the legs, hips, lumbar, shoulders, and head. Sleepers can create a customized set with Manual Mode, lock it in, and call it back instantly using the ReST app or tablet. The app also has a Position Mode that allows you to create more than one set of preferences. When you switch positions, you can also instantly switch the bed’s firmness in each region.
While on my back, I selected a pretty even and firm group of settings. I loosened up in the shoulder region when switching to my side for pressure relief in the shoulders. On my stomach, however, my hips still sank into the mattress no matter how firm I set it. The three inches of memory foam in the ReST’s top layer don’t get firmer or softer, so strict stomach sleepers may need a firmer build than the ReST can provide.
I was impressed that the sound of the air pump that changes firmness levels was never disruptive. This may be an advantage for combo sleepers who switch positions often — you won’t feel like you’re sleeping beside the train tracks every time you want to roll over to your side.
When I dialed down the ReST as low as it could go on the app, I felt a firmness ranking of about 4. Filling the air chambers as full as I could produced an 8 based on our 1 to 10 scale. 4 is soft enough for most sleepers to feel sunk into the mattress, while 8 should put most sleepers firmly on top of it.
Testing Out the ReST
I have a few tests that provide a more objective look at how the ReST performs. These tests usually include Pressure Relief, Bounce, and Motion Transfer. Because the ReST has its own built-in pressure map, we decided testing pressure relief here would be redundant. With this in mind, let’s move straight into the Bounce test.
The test for bounciness is simple. I drop a 10 lb. steel ball onto the mattress and make a visual assessment of the mattress performance. The ReST mattress has very little bounceback to it and the top layer of memory foam is the culprit. 3” of memory foam certainly provides comfort, but it tends to have a slow response to pressure.
A lack of bounce means that the average sleeper may feel a bit of tension when trying to change positions in bed. This is especially true if you have set the ReST to its softer settings. As you do so, you lose mobility, which is not one of this bed’s strong points to begin with.
After the bounce test, I use the same 10” ball for Motion Transfer tests. These tests are important to consider if you sleep with a partner. The more motion isolation you get in the ReST mattress, the less you feel it when your partner moves around at night.
I drop the 10 lb. steel ball from heights of 4 inches, 8 inches and 12 inches. Motion transfer is measured with a seismometer stationed where a partner would sleep across the bed. The lack of bounce I saw during the Bounce test translated into an impressive motion isolation test from all heights. If you have a restless partner, it is unlikely that you should feel disturbed even if that person is jumping in and out of bed all night.
Weighing the performance of the ReST against its competitors may be the best way to judge its potential, so here we go!
Sleep Number i10
- The i10 has a similar construction to the ReST — foam layers over air chamber support.
- Sleepers can change the i10’s parameters manually via remote control or use the automatic function included in the app. The Sleep IQ function allows sleepers to start customization from a template.
- Responsive Air Technology is the same as the automatic ReST function, but it only comes in the “Smart Series.”
- The i10 price range ranges from $5,099 (queen) to $5,799 (California king)

- The Solaire only offers manually adjusted firmness with a single parameter — a firmness range of 1 to 50.
- There is only one air mattress in the Solaire as opposed to five for the ReST. You are adjusting the entire bed when adjusting the firmness, not just a “body zone.”
- The build is similar to the ReST — memory foam over air chamber.
- In terms of cost, the Solaire is much less expensive than the ReST, with a range between $1,995 to $3,195.
