SONU Sleep System Overview

The Sonu Sleep mattress is no ordinary 14-inch bed; it’s a groundbreaking sleep solution crafted just for people who sleep on their sides. What sets it apart is its one-of-a-kind Comfort Channel feature, which lets your arms and shoulders sink into the mattress instead of just resting on top. Plus, you’re not stuck with just one level of firmness.

The Sonu Sleep mattress offers two distinct firmness options to cater to sleepers of all sizes, whether you’re on the lighter side or a bit heavier.



About Sonu Sleep

Meet Stason Strong and Brad Hall, two buddies who are also business partners with a shared love for all things sleep. They founded Sonu Sleep after figuring out that the usual flat mattresses just weren’t cutting it for a good night’s rest.

So, what did they do? They rolled up their sleeves and got to work, researching and developing a mattress that lets you actually sink your arms into the bed. The result? The Sonu Sleep mattress with its patented Comfort Channel design that hugs your arms and shoulders, lessens pressure, and boosts blood flow for a sleep that’s both comfy and restorative.

In our Sonu Sleep mattress review, we’re going to dig deep into:

  • The good and the bad (Pros and Cons)
  • What it’s like to open the box (Unboxing Experience)
  • How it feels to lie on it (Feel and Comfort)
  • What it’s made of (Construction and Design)
  • How well it performs (Performance Test Results)
  • All the nitty-gritty details like warranty, company policies, and any FAQs you’re curious about.

Just a heads-up: Our review will mainly focus on the plush version of the Sonu Sleep mattress, as we think it’s the most flexible choice for most folks. But don’t worry, we’ll also talk about which model could be the perfect fit for you as we go along.


Sonu Sleep Pros and Cons

First, let’s take a look at some of the pros and cons of the Sonu Sleep System:


  • One-of-a-Kind Comfort Channel: The star of the show is the patented Comfort Channel design. It’s like a cozy nest for your arms and shoulders, lessening pressure and boosting blood flow. This is a game-changer for side sleepers who often feel pressure on their arms and shoulders.
  • Choose Your Firmness: With Sonu Sleep, you get to pick between plush and firm models. Light sleepers will love the plush, while those who need more support will find the firm model perfect.
  • Spine-Friendly: This mattress is a chiropractor’s dream! The Comfort Channel lets your shoulders dip in, aligning the bones in your neck and upper back. Your upper body gets support, and your hips sink just enough to straighten the lower back. This all adds up to less stress, easier breathing, and a peaceful night’s sleep.
  • Built to Last: High-quality materials make this mattress a long-term investment. Plus, a 10-year warranty backs up its durability.
  • Feels Like a Cloud: The mattress is made from top-notch foam and quilted with a breathable fabric that’s soft to the touch, making your sleep experience feel luxurious.


  • A Bit on the Pricey Side: While the Sonu Sleep mattress offers a lot, it also comes with a higher price tag compared to other mattresses. But remember, you’re paying for quality and innovation.
  • Sheet Situation: The unique Comfort Channel design means regular bedsheets won’t fit perfectly. But don’t worry! Sonu Sleep throws in a free set of special bedsheets designed to snugly fit into the Comfort Channel, giving your arms and shoulders the support they deserve.

A mattress isn’t a one size fits all solution. Here are who we think would benefit the most from a Sonu Sleep System:

Side Sleepers

If you’re a side sleeper, the Comfort Channel design is your new best friend. It’s specifically made to relieve those pesky pressure points on your arms and shoulders. Plus, you get to pick between two firmness levels to find your perfect match.

Heavy Sleepers

For those who are on the heavier side, the Sonu Sleep mattress has got you covered with its firm model. It gives you all the support you need without making you feel like you’re sinking into quicksand.


Couples, rejoice! The Sonu Sleep mattress is perfect for lovebirds who like to snuggle but don’t want to feel squished or deal with arm and shoulder discomfort. Thanks to the Sonu Support Pillows, both you and your partner will enjoy a comfy and supportive sleep.

Techies and Bookworms

Do you love scrolling through your phone or diving into a good book before hitting the hay? The Sonu Sleep mattress is a dream come true. Its Comfort Channel design offers ergonomic support that lets you rest your hand comfortably, taking the strain off your shoulder and hand.

Plus, the sides of the Comfort Channel double as handy wrist rests, reducing any wrist tension you might have.



Sonu Sleep System Unboxing

When you’re shelling out for a premium mattress like the Sonu Sleep, you’re not just buying a bed; you’re buying an experience. And let me tell you, Sonu Sleep delivers big time! Your mattress arrives neatly rolled and compressed in a box, making setup a breeze.

So, how do you go from box to bedtime? First, slice open the box. Inside, you’ll discover a welcome kit that’s got a handy guide, a special Sonu cutting tool, your complimentary bedsheets, and of course, the star of the show—the mattress itself, along with its comfort pillows.

Next, pull your rolled-up mattress out and lay it on a solid surface, like your bed frame or even the floor. Don’t worry; it’s heavy but doable to handle solo. Use the Sonu cutting tool to carefully slice through the plastic wrap. You’ll see the mattress begin to puff up right away.

The corners will fill out fast too, which is a good sign of excellent corner expansion. Give it a few minutes to fully inflate, but you can totally snooze on it the same day.

One more thing: you might catch a whiff of a new-mattress smell when you first open it up. Don’t stress; it’s not a chemical odor. All the materials are eco-friendly and free from harmful stuff. The scent should vanish in a few hours and is totally harmless.


Sonu Sleep System Comfort and Feel

In this section we’ll break the Sonu Sleep System down, and discuss what you can expect when it comes to comfort.


The moment you stretch out on the Sonu Sleep mattress, you’re welcomed by a cover that’s as soft as it looks and cool to the touch. This isn’t just any fabric; it’s specially designed to stretch, making room for your arms and shoulders as they sink into the mattress.

Then comes the Comfort Channel, perfectly positioned to hug your shoulders and neck like they’ve never been hugged before. And let’s not forget the adjustable comfort pillows—you can tweak them to get the mattress feeling just the way you like it.

As you settle in, the mattress’s all-foam build wraps around you like a gentle hug. The foam strikes a balance—it’s firm enough to hold you up but soft enough to cushion every inch of you. You’ll feel your muscles unwind, letting go of all the day’s stress.

The longer you lie there, the more you’ll realize that this mattress has nailed the sweet spot between cushioning and support. It’s like you’re floating on a cloud, yet you’re supported exactly where you need to be.


When it comes to mattresses, firmness isn’t a one-size-fits-all deal. Your body weight, how you sleep, and what feels comfy to you are all key factors in picking the perfect firmness level.

Lucky for you, the Sonu Sleep mattress offers choices to fit all kinds of sleepers. You’ve got two options: the plush model, which scores a 4 on our firmness meter, and the firm model, which hits an 8 on the same scale.

Still scratching your head about which one to go for? Here’s a simple table to guide you. And remember, if you’re still on the fence, Sonu Sleep has got your back with a 100-night sleep trial to help you make up your mind.

The Sonu Sleep mattress is a dream come true for side sleepers, designed from the ground up to offer unparalleled comfort. But what if you’re not a side sleeper? No worries! This mattress is versatile enough to cater to all sleeping styles.

You see, the Comfort Channel isn’t a one-way street. You can choose to use it or not, depending on your preference. Want a more traditional, flat mattress feel? Just pop in the Sonu Comfort Insert into the channel, and voila! You’ve got yourself a flat sleeping surface.

This adaptability is a lifesaver for couples with different sleeping styles or for folks who like to switch things up and want less room in the Comfort Channel.

To really put the mattress to the test, we had our team of reviewers—each with their own unique sleeping style and body weight—try out the plush model.


Sonu Sleep System Construction


Now, let’s take a look at how the Sonu mattress is constructed, and the materials it uses.


The Sonu Sleep mattress isn’t just comfy; it’s also made with top-notch, eco-friendly materials. We’re talking about 26 pieces of high-resilience, CertiPUR-US®-certified flexible polyurethane viscoelastic foam that stack up to a full 14 inches of thickness. Translation? It’s green and safe for your home.

By this point, you’ve probably got a pretty good grasp of what sets this mattress apart. From the Comfort Channel to the Support Pillows, it’s engineered for the ultimate sleep experience. And let’s not overlook its style—the dark gray color scheme adds a touch of luxury and sophistication to your bedroom.


Forget what you know about traditional flat mattresses and their layer-upon-layer design. The Sonu Sleep mattress is a whole different ball game, featuring unique components that work together to give you the best sleep ever. Here’s what’s inside:

  • Support Pillows: These aren’t your average pillows. They’re made from a special foam that’s flexible sideways but super supportive vertically. This means they can cradle your upper body while taking the pressure off your arms and legs.
  • Comfort Channel: This is the patented magic that lets you sink right into the mattress. Imagine a 10-inch-deep space perfectly shaped to hold your body and keep your spine aligned. That’s the Comfort Channel for you.
  • Air Tech Layers: Made from Serene® foam, this layer lets air flow freely, so you stay comfy even if you’re a hot sleeper. It’s designed to offer different levels of support in one seamless layer—firm for your upper body and softer for your hips.
  • Channel Support: Picture three walls that shape the Comfort Channel into the perfect space for your arms and legs to sink into. These walls also double as hand rests when you’re holding a book or device.
  • Upper Torso Relief Layer: This layer is all about giving your upper body the support it needs while letting your arms and shoulders sink in. It’s like a weight off your shoulders—literally.
  • Sink Support: Designed for side sleepers, this layer helps align your spine, which means less tension, easier breathing, and a peaceful night’s sleep.
  • Cooling Cover: Made from a phase change material (PCM), this cover pulls heat away from you, keeping you cool all night. Plus, it’s stretchy enough to make room for your arms and shoulders as they sink into the mattress.


Sonu Sleep Performance

So, how good does the Sonu Sleep System perform? Let’s take a closer look:


If you’re someone who tends to get hot at night, or if you’re part of a couple that’s always fighting over the thermostat, the Sonu Sleep mattress has got you covered—literally. The cooling cover is crafted from a phase change material (PCM) that soaks up heat and lets it out slowly, keeping your body temperature nice and steady all night long.

But that’s not all. The Air Tech Layers are made from a foam that breathes easy, letting air circulate so you don’t get too warm. Plus, the Comfort Channel and Support Pillows make sure your body weight is spread out evenly, which also helps keep you cool.

To put it to the test, we did a cooling performance experiment. We laid on the Sonu Sleep mattress for 20 minutes and kept an eye on how well it held onto heat. Right off the bat, the cool, soft fabric of the cover felt amazing against our skin. As time passed, the mattress molded to our bodies, but we didn’t start sweating or feel too hot.

For a mattress made entirely of foam, it did an excellent job at staying cool. We were so impressed that we gave it a 4.6 out of 5 for its cooling performance.


The Sonu Sleep mattress is engineered to minimize motion transfer, so it might not be the springiest mattress you’ve ever tried. But don’t let that fool you—our tests show it’s still pretty responsive.

To gauge how quickly the mattress bounces back, we placed a 20-pound ball on it and waited a few moments for it to settle in. Then, we lifted the ball off and timed how fast the mattress returned to its original shape. The result? A full recovery in just about 1.3 seconds, earning it a solid score for responsiveness.

Even though it’s an all-foam mattress, the Sonu Sleep system performed admirably in our responsiveness test. You won’t feel like you’re sinking into quicksand; it’s got enough bounce to keep you comfortable. That’s why we rated it a 4.2 out of 5 for responsiveness.

If you’re on the hunt for something with a bit more spring, you might want to consider the firm model of this mattress.

Motion Isolation

If you’re sharing a bed, the last thing you want is to be jolted awake every time your partner moves. That’s where the Sonu Sleep mattress shines. Its viscoelastic foam is a lot like memory foam, molding to your body and cutting down on motion transfer.

To see just how good it is at keeping things steady, we ran a couple of tests. First, we set a glass of water on one side of the mattress and dropped a 20-pound ball on the other side. Guess what? The water didn’t even ripple.

For our second test, one person lay still on one side of the mattress while another person tossed and turned on the other side. The result? The person lying still didn’t feel a thing.

Both tests prove that the Sonu Sleep mattress is a champ at isolating motion.

Edge Support

Edge support might not be the first thing you think of when mattress shopping, but it’s crucial if you like to sleep or sit near the edge. Even though the Sonu Sleep mattress doesn’t have springs, it still offers impressive edge support thanks to its specialized foam layers designed for stability.

To put it to the test, we applied some serious pressure to the mattress edges and checked for any pushback. The mattress did a great job, offering enough counterpressure to make us feel secure. When we let go, the edges bounced back nicely, although they were a bit softer near the Comfort Channel.

Sitting on the edge, we noticed a slight dip as our weight settled in, but it didn’t feel like we were about to slide off or anything.


If you’re sharing your bed, the last thing you want is a noisy mattress that broadcasts every move you make. Good news: the Sonu Sleep mattress is designed to be as quiet as a mouse, thanks to its all-foam construction.

To see if it lives up to the hype, we conducted a noise test. We dropped a 20-pound ball onto the mattress and used ultra-sensitive microphones to pick up any sounds. Guess what? It was virtually silent. The only noise we heard was the soft thud you’d expect from dropping something onto any surface.

That’s the beauty of an all-foam mattress—there are no springs or other noisy materials to disturb your peaceful slumber.

So, when it comes to noise isolation, the Sonu Sleep mattress is a real winner.


When it comes to the bedroom, you want a mattress that’s got the right mix of bounce, cooling, and support. The Sonu Sleep mattress checks all those boxes. Its slightly springy surface makes it easy to move, while the viscoelastic foam keeps you from sliding around.

Edge support is also solid, allowing you to utilize the entire mattress. However, some couples might find that the softer model causes them to sink a bit, which could restrict movement. If that’s a concern, the firm model is a good alternative.

Pressure Relief

Pressure relief is a big deal for anyone who values quality sleep, whether you’re an athlete or just someone who wants to wake up feeling refreshed. The Sonu Sleep mattress is engineered to be a pressure-relieving superstar, especially for side sleepers. It’s even got the thumbs-up from chiropractors!

To see how well it performs, we conducted our standard pressure relief test. This involved lying on the mattress for 20 minutes and then measuring the pressure across different areas of the body. The results? Pretty impressive, as shown by our pressure map.

For side sleepers, the map was a sea of blue, thanks to the Comfort Channel and the special layer designed to relieve pressure on the upper torso. That means zero pressure points, which is crucial for side sleepers who often feel the squeeze on their shoulders and hips.

As for stomach and back sleepers, the map showed just a hint of green, which is pretty standard for most mattresses. This is especially noteworthy given that the Sonu Sleep mattress is on the plush side.

Company Policies

How does Sonu Sleep stack up when it comes to things such as warranties, returns and sleep trial? Let’s have a look:


When you invest in a Sonu Sleep mattress, you’re also getting the reassurance of a 10-year limited warranty. This warranty has got you covered for any defects in the materials or craftsmanship of the mattress. However, it’s important to note that the warranty won’t apply if the mattress is damaged due to incorrect handling, like lifting it by the Comfort Channel.

Also, keep in mind that this warranty is only valid for mattresses that are purchased directly from Sonu Sleep and are used within the United States.

Sleep Trial

Worried about committing to a new mattress? Don’t be. Sonu Sleep offers a 100-night risk-free trial that lets you test out the mattress right in the comfort of your own home. If it turns out the mattress isn’t the dreamy fit you hoped for, you can return it within those 100 nights and get a full refund.


So, you’re within your 100-night trial and thinking about a return? Sonu Sleep allows for full refunds, but there’s a catch—you have to wait at least 60 days after delivery. This gives your body time to adjust to the new mattress.

To initiate a return, you’ll need to reach out to Sonu Sleep and provide all the necessary details. Keep in mind, you’ll be on the hook for the return shipping costs, which will be subtracted from your refund. And if you’re in Alaska or Hawaii, extra shipping charges may apply.

Got an unopened mattress? You can return it, but only within 30 days of delivery. If it’s still sealed after 30 days, it’s considered misused and won’t be eligible for a return or warranty claim.


Good news for folks in the contiguous United States: Sonu Sleep offers free shipping on all their products, including the Sonu Sleep System. But, if you’re in Alaska or Hawaii, there’s a little extra to consider. Shipping to these areas comes with an additional charge.


Frequently Asked Questions

Here are some of the most frequently asked questions pertaining to the Sonu Sleep System:

Will my arm fall asleep or become numb in the sleep channel?

No, it will not. Your arm falling asleep is all about circulation—or the lack of it. This happens when you’re on a traditional flat mattress, and your arm ends up in an awkward position that cuts off circulation.

Enter the Comfort Channel in the SONU Sleep System. This ingenious feature isn’t just about comfort—it’s about keeping that blood flowing. By providing a cozy space for your arms to rest below heart level, the Comfort Channel works its magic.

It’s all about maintaining the natural position your arms would be in while you’re awake, which means no more awkwardly positioned limbs and no more circulation cut-offs. Say goodbye to the tingly “asleep” feeling and hello to restful sleep with the SONU Sleep System.

What kind of bed frame or platform should I use?

The Sonu Sleep Mattress is compatible with platform bases, box foundations, and adjustable bed frames, provided they are strong and stable. If you often prefer sitting up, we recommend an adjustable foundation.

When using foundations with cross slats, make sure slats are spaced 1″ apart under the Comfort Channel and 3″ or less apart for optimal support elsewhere on the mattress. To prevent sagging, it’s best to avoid using spring-based foundations Finally, position the head of the mattress (where the Comfort Channel is) against a solid vertical surface like a wall or headboard.

Can I clean the mattress cover of the SONU Sleep System?

Absolutely, you’re in luck! The SONU mattress cover can be spot cleaned using a gentle, mild detergent or hand soap. Keep in mind that our mattress covers aren’t meant to be removed.

Can I finance my SONU purchase?

Certainly! For our valued customers in the U.S., we offer the convenience of financing through our partner, Affirm. To learn more about the financing options available, please visit the Financing page on our website.
