“Sonu is by far the best possible solution for shoulder issues. So good, in fact, there isn't anything even close.”

Curt B.

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.
