This rectangular mattress protector is designed specifically for indoor use within the bedroom environment. It serves as a cover for bedding to shield it from liquid spills and everyday wear. The product features synthetic thermoplastic polyurethane (TPU) material as its cover component. This synthetic TPU layer provides water-resistant properties, which helps prevent liquids, spills, and moisture from passing through to the bed underneath, keeping the sleeping surface dry. For structural reinforcement in its construction, the cover is manufactured using overlock technology. This overlock stitching method secures the fabric edges, which prevents fraying along the seams and supports the cover during regular handling. Additionally, the mattress protector is designed with a 75 GSM knitted skirt that extends along all four sides. This four-side knitted skirt wraps around the mattress edges to help secure the cover in place, preventing shifting or sliding during sleep. The 75 GSM weight of the skirt provides a steady hold on the mattress corners, helping the cover remain flat and smooth across the entire bed surface. Regarding safety and material standards, the textile is OEKO-TEX Standard 100 certified, carrying the certificate number SH025 226280. This certification signifies that the fabric has been thoroughly tested for harmful substances, making it suitable for direct contact in indoor sleeping spaces. Appropriate for residential bedrooms, guest accommodations, and other indoor environments, this rectangular TPU cover fits over the bedding to serve as a functional barrier against moisture while maintaining a stable position on the bed.
