Can the Eight Sleep Pod 4 track your sleep?

Eight Sleep claims the Pod 4 and Pod 4 Ultra feature 'clinical-grade sleep and health tracking', including heart rate, sleep stages, and respiratory rate tracking. With sensors built into the mattress cover, the Eight Sleep can understand your rest from head to toe.

If you want to know more about your sleep but you've found fitness tracking wearables uncomfortable or inaccurate, the Eight Sleep is an excellent alternative (albeit, a pricey one). For more information, check out our comparison of smart beds vs sleep trackers.
