SONU Sheet SetFREE$249 Value for King

The Patented SONU Comfort Channel

The only mattress that allows your arms and shoulders to fully immerse into the bed, made possible by the Comfort Channel.


The Support Pillows

Each SONU Sleep System comes with 4 Support Pillows that fill the Comfort Channel (2 for Twin XL). On top of these Support Pillows, at least one top pillow per sleeper is required. We recommend the SONU Top Pillow Deluxe as it is designed to work with the system.


Cooling Cover

Woven into the cover is a PCM, or phase change material, that ablates heat away from the sleeper, so it is cool to the touch and helps regulate temperatures throughout the night.

At 14 inches deep and constructed from 26 pieces of premium high-resilience CertiPUR-USยฎ certified environmentally friendly foams, the SONU is durable and built to provide ideal support in all the right places.


Sink-In Support System

Adjustable Head & Neck Layers

Change the resting height of your head to perfectly level your neck while side sleeping. Laterally malleable pillows allow consistent vertical support while accommodating relaxing space for shoulders and arms.


Channel Waterfall

Soft cover material flows seamlessly down into the Comfort Channel, ensuring all surfaces touched while sleeping are free of cover fabric joins to allow for an all encompassing smooth experience.

Every Side Sleeper's Dream

Prepare for comfort you never thought possible. The SONU Sleep System reduces pressures in a way that will rejuvenate you every night. No other mattress even comes close.

The Comfort Channel

The patented Comfort Channel of the SONU Sleep System allows for the full range of motion of the shoulder and arms within the mattress, not just on top. Side sleepers benefit from not needing to roll over to relieve pressure on arms and shoulders constantly, resulting in sound sleep throughout the night.

The Support Pillows

The patented Support Pillows of the SONU are the key to the unique immersive support system. Each SONU has a stack of two layers of Support Pillows, and within each are individual layers particularly engineered to allow the pillow to be laterally malleable while maintaining ideal vertical support.

Sink-In Support

The SONU is designed to align the spine while side sleeping, enabling reduced tensions, better breathing and sound sleep throughout the night. This feat is accomplished by allowing the shoulders to immerse into the Comfort Channel, leveling the vertebrae in the neck and upper back, while supporting the upper torso, allowing the hips to sink in, leveling the vertebrae in the lower back.

Upper Torso Relief

The gradating levels within the SONU have been engineered to support the upper torso, commonly the heaviest part of the human body, while allowing the shoulders and arms to immerse into the bed below, dramatically reducing the weight normally required by these areas to support the upper torso. The result is a truly unique level of comfort and an unforgettably relaxing sleeping experience.

โ€œi have suffered from shoulder pain while sleeping for several years, i had just about given up... then i saw this bed and decided one last try. i can't begin to explain what it feels like to sleep through an entire night... for the first time in 20 years the first weekend i had it. I'm so impressed with this bed... because what they are making is making a difference in people's lives.โ€

โ€œThis comfort channel they made is next level. I never imagined that I would be able to put my arm in the mattress. Takes all the pressure off my shoulder, which I so so need. YESโ€
Kim J.
Highly recommended!
โ€œIโ€™m a side sleeper and I used to wake up with a dead feeling arm from lying on it all night. Finally a mattress with a pocket for my arm. I tried all the pillows and even very expensive mattresses in the past, but nothing cured my circulation problems until I got the sonu sleep mattress. I love it!โ€
Nic D.

โ€œ...Sonu mattresses are in a league all by themselves. This is the most comfortable bed I have ever slept on. I have no more shoulder pain and numbness. I can now sleep through the night and not wake up in pain. If anyone is even thinking about getting a Sonu sleep system donโ€™t think anymore. Pull that trigger. I 100% gaurentee you will not be disappointed.โ€

The SONU Comfort Insert fills in one side of the Comfort Channel, making the SONU Sleep System more akin to a flat mattress, but still with give for your shoulders. This versatility can be helpful for many scenarios including couples who sleep differently from one another (e.g. a side sleeper and a back sleeper) and for those who simply prefer less space in the Comfort Channel.

Frequently Asked Questions
Contrary to what some might believe, the Comfort Channel is not conducive to numbness or tingling in your arm. When a body part โ€œfalls asleepโ€, as the saying goes, it is due to lack of circulation, or not enough blood reaching the body part. When your arm starts to tingle or loses feeling it is caused by a position you are in that is cutting off this necessary circulation that supplies oxygen to the nerves that run between your neck and your arm. Nerves have their own blood supply, so pressure on a nerve cuts off that blood supply and the nerve becomes starved for oxygen and shuts down. This happens often on traditional flat mattresses as you are forced to overextend your shoulders and arms into positions in which they are not meant to rest, which can cut off this circulation. While side sleeping on a flat mattress you are forced to apply unavoidable pressure on these body parts which results in the discomfort and lack of circulation that can cause this numbness. The SONU Sleep Systemโ€™s patented Comfort Channel design helps to greatly relieve these pressures on your arms, and with this relief comes improved circulation and reduced chances of numbness.

Some may look at the SONU design and believe that because your arms are below the rest of your body, you may have an increased risk of circulation issues or numbness. This is a common misconception, but is not the case - hereโ€™s why. Your arms are naturally below your heart when you are upright, walking or sitting, throughout the day. Your arms never tingle in this position because they are receiving the correct amount of circulation. The Comfort Channel enables your arms to also rest below your heart, as if you were upright, resulting in your arms receiving the correct amount of circulation โ€“ which actually reduces the chances of circulation issues or numbness, compared to flat mattresses. We have designed the Comfort Channel system with all of this in mind. You will be impressed at the elevated level of comfort and truly deep sleep you will enjoy on your SONU, enabled in part by the improvement in circulation your body will experience.

When we set out on this journey to create the worldโ€™s first mattress for side sleepers that incorporates groundbreaking innovations unlike anything else on the market, we had to fight against the grain in an industry that hasnโ€™t changed much in decades - all while battling dramatically increased cost of goods, shortage of labor and supply chain delays caused in large part by the pandemic. Other companies selling traditional flat mattresses that consist of only a few parts, buy low quality goods in bulk and manufacturer their products overseas, while incorporating corner-cutting processes into their production. By vast contrast, we create each SONU Sleep System by hand, as our design requires 26 custom components, top quality materials and the highest level of detail at which we hold ourselves as a brand. Every SONU is assembled by our skilled technicians in our factory in California, then thoroughly inspected before we package with care and FedEx to your door. This is why our products have a higher price than some others on the market โ€“ everything about SONU is entirely unique and of the highest quality โ€“ and you feel these incredible advantages every night when you immerse into comfort. You will discover that no other mattress even comes close.

Weโ€™ve partnered with the financing company, Affirm, to be able to offer attractive monthly payment options. If this is something youโ€™re interested in, it is good to note that Affirm extends your timeline and drops your monthly payment amount when your total is above $3,000. For example, if you select a queen size SONU and want to get our advertised $84 per month, then add an accessory to your cart (a Top Pillow Deluxe or our Mattress Removal option perhaps) so your total is just above $3,000 โ€“ then you will see the monthly payment price decrease. Once everything looks good, proceed by checking out and selecting โ€˜Affirmโ€™ when you get to the payment section.

We just know youโ€™ll be amazed with how our invention will transform your quality of sleep and rejuvenate you every night. We truly hope you join us and embark on a new chapter of comfort in your life.

Thank you so very much and sweet dreams,
The SONU Sleep Team

We are currently shipping mattresses within 3 to 5 days! SONUs are made-to-order, so on occasion it may take a little more time to get to you, as theyโ€™re not sitting in a warehouse collecting dust.

FedEx will deliver your SONU to your door, no signature required.
You can pair the SONU with any platform, box spring, bed frame or simply the floor, as long as the headboard area of the mattress is flush against a solid surface for support. We also highly recommend using an adjustable foundation.
