Sonu Sleep created a design around a patented "Comfort Channel" that gives arms and shoulders a negative-space pocket to sink into instead of compressing against a flat surface.

Founded by engineer Stason Strong after years of designing and testing, the SONU Sleep System is handcrafted from 26 custom components and manufactured in the USA, addressing the shoulder pain, arm numbness, and restless sleep that side sleepers have lived with on traditional mattresses. The brand has become known among physical therapists, chiropractors, and even pro athletes as a genuine solution for pressure relief during sleep.
