Unlike PVC or vinyl-backed protectors, this TPU membrane is micro-porous - it blocks liquid while allowing moisture vapour to pass through, reducing heat build-up. TPU is also free from plasticizers and phthalates, requires less energy to produce than PVC, and can be disposed of at standard waste treatment facilities.𝗚𝗢𝗧𝗦 𝗖𝗲𝗿𝘁𝗶𝗳𝗶𝗲𝗱 𝗢𝗿𝗴𝗮𝗻𝗶𝗰 𝗖𝗼𝘁𝘁𝗼𝗻 𝗦𝘂𝗿𝗳𝗮𝗰𝗲 - 𝗪𝗵𝗮𝘁 𝗧𝗼𝘂𝗰𝗵𝗲𝘀 𝗬𝗼𝘂 𝗜𝘀 𝗢𝗿𝗴𝗮𝗻𝗶𝗰: The surface you sleep on is GOTS certified long-staple organic cotton - grown without synthetic pesticides, processed without harmful chemicals, verified at every stage from field to finished fabric. The organic cotton layer is what directly contacts your skin every night. The TPU waterproofing layer is laminated beneath the cotton and never contacts your skin. GOTS certification applies to the cotton fabric; the complete finished product carries OEKO-TEX Standard 100 certification - every component tested against 100+ harmful substances, including the TPU membrane.𝗡𝗼𝗶𝘀𝗲𝗹𝗲𝘀𝘀 - 𝗡𝗼 𝗖𝗿𝗶𝗻𝗸𝗹𝗲, 𝗡𝗼 𝗥𝘂𝘀𝘁𝗹𝗲, 𝗡𝗼 𝗣𝗹𝗮𝘀𝘁𝗶𝗰 𝗙𝗲𝗲𝗹: The micro-porous TPU membrane is specifically engineered to be noiseless - no crinkle, no rustling when you move, no plastic-sheet feel. Unlike thicker PVC-backed protectors that make audible sounds with every movement, the thin TPU lamination flexes silently with the cotton surface. After the first wash, the cotton surface becomes noticeably softer and the protector conforms more naturally to the mattress. If any initial stiffness is noticed out of the package, one wash cycle resolves it entirely.𝟭𝟵" 𝗗𝗲𝗲𝗽 𝗣𝗼𝗰𝗸𝗲𝘁 - 𝗔𝗹𝗹-𝗔𝗿𝗼𝘂𝗻𝗱 𝗘𝗹𝗮𝘀𝘁𝗶𝗰, 𝗦𝘁𝗮𝘆𝘀 𝗦𝗲𝗰𝘂𝗿𝗲 𝗼𝗻 𝗔𝗻𝘆 𝗠𝗮𝘁𝘁𝗿𝗲𝘀𝘀: An all-around elastic skirt with 19-inch deep pockets accommodates mattresses from standard depth (8–10") through pillow-top and extra-deep (up to 19"). The organic cotton skirt stretches to grip the mattress firmly on all four sides and corners. For full waterproof protection, all four corners must be fully seated against the mattress - check that no gaps exist at the corners before use. If your mattress is at or near the 19" maximum, confirm the protector is fully anchored before sleeping on it. Measure your mattress depth before ordering.𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗪𝗮𝘀𝗵𝗮𝗯𝗹𝗲 - 𝗖𝗮𝗿𝗲 𝗚𝘂𝗶𝗱𝗲 𝗳𝗼𝗿 𝗟𝗼𝗻𝗴-𝗧𝗲𝗿𝗺 𝗧𝗣𝗨 𝗣𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻: Machine washable on gentle or delicate cycle with warm water and a mild non-phosphate detergent. Tumble dry on low heat only - the TPU membrane is permanently damaged by high heat, which degrades the waterproof lamination over time. Do not use hot water wash cycles. Do not bleach or iron. For longevity: wash monthly or after any spill event, always tumble dry low, and store flat or loosely rolled - never compressed. The organic cotton surface softens with each wash. No vinyl, no PVC, no phthalates, no latex - confirmed safe for children, babies, & chemically sensitive sleepers.
