Eight Sleep
Mattress cover that actively heats and cools each side of the bed
Cool for sleep onset, cooler in the middle of the night, warmer before waking: a water-circulating mattress cover changes temperature through the night and tracks sleep along the way. It targets the one sleep variable most people cannot fix with a thermostat, especially couples who disagree about temperature. Genuinely expensive, involves a subscription, and a frequent podcast sponsor.
