Ever since the Clarisonic, my obsession with wellness tech has littered our home with pelvic-floor trainers, vibrating eye masks, and more red lights than central Amsterdam. Nearly all were about as useful as Siri.
When the Eight Sleep’s coffin-size boxes darkened our door on a dreary autumn day in 2024, my formerly unflappable husband wailed, “This is my limit!” But soon he, too, was enamored. This mattress pad, covered in capillaries and attached to a water tank that tracks the body’s sleep stages and heats and cools to optimize them, turned my sweetie into someone who shares a passion with Bryan Johnson, as he sinks into the pre-heated bed, blissfully sailing from deep sleep to REM and back again without even stirring.
