Sleep tech bed now estimates your biological aging as you snooze
Eight Sleep’s Pod mattress now includes a Biological Age feature that passively tracks aging pace and biological age while you sleep, using sensors in the mattress cover (and optional data from a wearable) to measure heart rate, HRV, respiration, sleep stages and duration, with validation against clinical standards; developed with biohacker Bryan Johnson, it aims to make longevity data actionable in daily life, and the latest Pod costs $2,999 with a five‑year warranty and a 30‑night trial.
