A 35-year-old Caucasian female host: "Do you long for a dry and peaceful night's sleep every night, but are troubled by accidental spills, pet paw prints, or little accidents from your children? Don't worry! Today, I'm bringing an 'invisible guardian' to all American families who pursue high-quality sleep – our professional-grade waterproof mattress protector!" (Camera zooms in, showing the fabric details of the mattress protector) "It's not just 'waterproof,' but also a guarantee of 'peace of mind.' It achieves 100% complete waterproofing – liquids behave like raindrops on a lotus leaf, naturally sliding off without penetrating! At the same time, it boasts excellent breathability, ensuring that while protecting your mattress, you won't feel stuffy or have a plastic-like feel. Its comfort is comparable to high-end pure cotton mattress protectors." (Camera switches: Demonstration scene – pouring water onto the surface of the mattress protector, showing the water droplets beading up without penetrating; or wiping with a tissue to demonstrate its dryness) (End screen: Product close-up + brand slogan) Subtitles/Voiceover: "[MEELUS] Waterproof Mattress Protector – We protect your peaceful sleep with care."
