SIDE SLEEPING TECH

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.

1
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.

What Sets SONU Apart

Never before has a mattress enabled sleepers to fully immerse, eliminating pressure that has been unavoidable until now.

Perfect Firmness
On a scale of 1 to 10 the SONU Firm mattress is an 8 in firmness, enabling relief while bolstering support where needed, for a brilliantly strong yet balanced sleeping experience. For a softer and more cushioning experience, please view the SONU Plush mattress, or for a more supportive experience with bounce, please view the SONU Hybrid mattress.

All Foam vs. Hybrid
ALL FOAM CONSTRUCTION
The SONU Plush and Firm models are constructed entirely from premium quality foam parts, engineered for maximum motion isolation, so if your partner moves during the night, you are less likely to be disturbed.
HYBRID CONSTRUCTION
The SONU Hybrid model is constructed from the same premium foam parts as the Plush and Firm, but with a layer of individually pocketed coil springs to add bounce and increase airflow, in place of the main body foam layer.

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 β€œfalls asleep”, 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 System’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 - here’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 – 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 world’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 hasn’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 either our California or Connecticut factory locations, 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 – everything about SONU is entirely unique and of the highest quality – and you feel these incredible advantages every night when you immerse into comfort. You will discover that no other mattress even comes close.

We’ve partnered with the financing companies, Affirm and Koalafi, to be able to offer attractive monthly payment options. If this is something you’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 – then you will see the monthly payment price decrease. Once everything looks good, proceed by checking out and selecting β€˜Affirm’ when you get to the payment section. Koalafi also offers payments over time with their lease-to-own program, which can be beneficial to customers who are still building credit. For details please visit the Financing page.

We just know you’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

Back to top...
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 they’re not sitting in a warehouse collecting dust. The mattress, once compressed, will ship directly to your door. You will be emailed a tracking number as soon as your order ships.
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.
Every SONU’s height is 14 inches, while the width and length dimensions are the same as standard U.S. mattress sizes. The Comfort Channel dimensions describe the negative space in the mattress, while the Support Pillow dimensions describe a single pillow, of the 2 for Twin XL and 4 for Queen, King and Cali King, that are stacked in the Channel.

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.
