EarthPulse's On Command ($500) turns your bed into a "magnetic cocoon." Placed under your mattress, the device transmits mild electromagnetic waves lulling your body to sleep. Claims like "enhanced cellular energy" and "the most significant longevity and performance-enhancement discovery ever made" make me question On Command's scientific credibility, but for the sleep-challenged, any alternative to tossing and turning is probably worth trying. A 90-day money-back guarantee should provide some comfort for skeptics. — Trevor Noren
