The Sleep System
The SONU Sleep System is the world's first mattress engineered specifically for side sleepers, featuring a patented Comfort Channel — a 10-inch-deep negative space that lets arms and shoulders sink in rather than getting pinned underneath the body.
Layered Support Pillows inside the channel stay laterally malleable while maintaining vertical support for the head, neck, and upper torso, helping align the spine and reduce the tension that typically causes side sleepers to wake up and roll over. It's hand-built in the USA from 26 custom, CertiPUR-US certified components, with a cooling cover to help regulate temperature through the night.

"I tried many remedies but none solved my problem until I discovered the Sonu mattress with the cut out arm channels. This has become a game changer. No more shoulder pain, no more dead arms, and the most comfortable sleep I have had in years."
