Smart mattresses go beyond comfort — they track your sleep, adjust firmness automatically, regulate temperature, and integrate with your health ecosystem. The best smart mattresses make sleep data actionable and genuinely improve your rest over time.
What Makes a Mattress “Smart”?
Smart mattress features vary by model and brand. Core capabilities include: sleep tracking (heart rate, breathing, movement), automatic firmness adjustment, temperature regulation, smart alarm (wake at lightest sleep phase), and app integration with Apple Health, Fitbit, and other platforms.
Best Overall Smart Mattress: Eight Sleep Pod 4
Eight Sleep’s Pod 4 is the most advanced smart mattress technology available. The Active Grid system heats and cools each side of the bed independently between 55°F and 110°F — transformative for couples with different temperature preferences. Sleep tracking via embedded sensors provides heart rate, HRV, and respiratory rate data. Smart alarm wakes you at the optimal moment in your sleep cycle.
Best Smart Air Mattress: Sleep Number 360 i8
Sleep Number’s smart tier combines their adjustable air technology with biometric sleep tracking. The SleepIQ system learns your preferences and automatically adjusts firmness through the night. Best for those who want data-driven firmness optimization rather than active temperature control.
Best Budget Smart Option: Withings Sleep Analyzer (Pad)
Not technically a mattress, but worth mentioning: the Withings Sleep Analyzer is a sensor pad placed under any mattress that provides clinical-grade sleep tracking at a fraction of smart mattress prices. It detects sleep apnea risk, tracks sleep cycles, and integrates with Apple Health. An affordable way to add smart tracking to any mattress.
Eight Sleep vs Sleep Number: Key Difference
Eight Sleep focuses on temperature regulation — the Pod 4’s active cooling and heating is its defining feature. Sleep Number focuses on firmness customization via adjustable air. Both offer sleep tracking. Choose Eight Sleep if temperature control matters most; choose Sleep Number if firmness adjustability is the priority.
Smart Mattress Subscription Costs
Many smart mattress features require ongoing subscriptions. Eight Sleep Pod 4 requires an Eight Sleep membership (~$17/month) for full smart features. Sleep Number’s basic features work without subscription but premium insights require SleepIQ+. Factor ongoing costs into your total ownership calculation.
