The EightSleep Story
EightSleep was founded in 2014 by Matteo Franceschetti and Alexandra Zatarain. The company is based in San Francisco, CA. Smart mattress covers with active temperature control for better sleep.
Why EightSleep?
I used to be the person who kept the thermostat at 68 degrees year-round and still woke up sweaty in summer. My partner, meanwhile, was always cold and piled on blankets. Enter EightSleep's Pod 4 — a smart mattress cover that replaces your existing mattress topper and pumps temperature-controlled water through micro-tubes to heat or cool each side of the bed independently. The first night I set my side to 65 degrees and my partner set theirs to 78, and we both slept through the night without touching the thermostat. The Pod 4 also tracks your sleep, heart rate, HRV, and respiratory rate, and uses AI to auto-adjust your temperature based on your sleep stage. It is expensive — around $2,000 — but for couples with mismatched temperature needs, it solves a problem no other product addresses.
Hero Product: EightSleep Pod 4 Cover
The Pod 4 is EightSleep's latest and most advanced smart mattress cover. It sits on top of your existing mattress like a fitted sheet and connects to a bedside Hub that circulates water through an intricate grid of micro-tubes embedded in the cover. Key features include: independent dual-zone temperature control (a 55-degree range per side), Autopilot AI that learns your sleep patterns and adjusts temperature proactively, biometric tracking (heart rate, HRV, respiratory rate, movement, and sleep stages), gentle Smart Alarm that wakes you at the optimal sleep stage by warming your bed two degrees, and a quiet vibration alarm. The Pod 4 is 40% quieter than the Pod 3, uses a new Hydro-Engine pump for faster temperature changes, and has an improved fabric feel. It works with any mattress up to 15 inches thick.
Real User Reviews
On Reddit's r/EightSleep, the consensus is that the product delivers on its promise for couples with different temperature preferences. One user posted: 'I have the Pod 4. My wife keeps her side at 74, I keep mine at 64. We both sleep great. No more thermostat wars. Simple as that.' On Trustpilot, EightSleep averages 3.8 stars from 900+ reviews. Criticisms include the Autopilot subscription ($19.99/month after a one-year free trial) and occasional reliability concerns (some users report water pump noise after 6-12 months). The company has improved warranty coverage and customer support responsiveness in the Pod 4 generation. A common tip: keep the Hub on a hard surface (not carpet) for quieter operation and better water flow.
