SONU Sleep targets side sleepers who experience discomfort, poor circulation or restless nights on conventional flat mattresses. The brand occupies the premium segment of the mattress market, justifying higher price points through patented engineering, American manufacturing and a material cost structure that differs from mainstream mattress brands. The core product philosophy is built around negative space: a recessed Comfort Channel built into the mattress allows arms and shoulders to rest below the sleep surface rather than being compressed against it. SONU offers three firmness variants (Plush, Hybrid and Firm), a 100-night trial period, free shipping and financing options starting at 0% APR, making the premium price more accessible for a range of budgets.

Will my arm go numb when sleeping in the Comfort Channel?
According to SONU Sleep, the Comfort Channel is designed to reduce pressure on arms and shoulders rather than increase it, which should improve circulation compared to sleeping on a flat mattress. The channel positions the arm below the heart, similar to how arms rest during the day when standing or sitting, which is a natural position that typically does not cause numbness.
