Part meditation coach and part teddy bear, this kidney-shaped “robot” is a cuddle-buddy that soothes you to sleep with its mechanical breathing. Somnox snuggles comfortably into your arms at bedtime without straining your neck or shoulders, while its body pulses rhythmically with deep inhalations and smooth exhales. Accelerometers and CO2 sensors help it automatically match your respiration rate, then gradually slow down to coax you into a similar speed—and a state of relaxation. The accompanying app also has settings for waking-anxiety reduction and sweet, sweet naps.
