The Kettlelark™ 360° Smart Sensing Mattress Encasement

🛡️ Total Mattress Protection: Designed to protect expensive US mattress investments, this ultra-thin, crinkle-free encasement completely zips around your mattress. Crafted from a breathable Tencel™ membrane, it is 100% waterproof, hypoallergenic, and certified bed-bug-proof. 📊 Invisible Sleep Lab & Health Tracking: Unlike bulky wearable rings or smart watches that can be uncomfortable to wear at night, BioShield™ features micro-ballistocardiograph sensors seamlessly woven into the chest-level fabric. It passively tracks heart rate variability (HRV), respiratory rate, and sleep stages for two sleepers independently. 📱 Seamless Smart Home Integration: Syncs effortlessly with Apple Health, Google Fit, and smart thermostats. If the sensors detect elevated body temperatures or restless tossing, it can automatically signal your smart AC or ceiling fan to lower the room temperature.
