In today's fast-paced world, sleep is more than just rest—it's a data-driven science. The Sleep Number i8 bed steps into this arena as a high-tech adjustable airbed designed for modern sleepers who crave customization. With dual air chambers, this 14-inch profile mattress lets each partner dial in their ideal firmness level independently, from extra plush to ultra-firm, using a remote or app. What sets it apart is the integrated SleepIQ technology, which tracks over a dozen sleep metrics like heart rate variability, breathing rate, and movement patterns to deliver weekly insights for better rest.
Priced in the premium segment (typically $3,000–$5,000 for a queen, depending on retailer promotions), the i8 promises not just comfort but actionable health data. We've tested it alongside everyday use cases, scoring it across key categories to see if it lives up to the hype. Whether you're a couple with mismatched preferences or a tech enthusiast optimizing sleep, read on for our in-depth analysis.
The core of the i8 is its dual-adjustable air chambers, supporting up to 400 lbs per side. Adjust firmness in seconds via the Sleep Number app or remote—no tools needed. This responsiveness shines for side sleepers needing contouring or back sleepers wanting lumbar support.
SleepIQ goes beyond basic step counters. It monitors sleep efficiency (aim for 85%+), duration, and quality stages (REM, deep, light). App dashboards show trends, like how a 60 firmness setting improved your deep sleep by 20%. Pair it with compatible wearables for fuller insights.
At 14 inches tall, it features:
This setup excels in motion isolation (65/100), minimizing disturbances for light sleepers.
