Premium Waterproof Protection: Block oil, water-based, and silicone-based massage products from soaking through to your mattress. The bonded TPU top layer locks out spills, sweat, and stains so the bed underneath stays dry, clean, and odor free. Tailored King Fit: Sized to fit a King mattress (72'' x 80'') with a 14'' deep pocket. The breathable elastic black skirt grips firmly with no bunching, sliding, or tangled corners during use. (Note: this is the AU/UK King size, not the US standard 76'' King.) Quiet, Soft, Hassle-Free: No crinkly plastic feel, no rustling noise. Hypoallergenic and stain-resistant, this waterproof bed sheet is fully machine washable and dryer safe, so cleanup after a massage or spa session takes minutes, not hours. Built To Last: 95% polyester and 5% spandex bonded with an advanced TPU waterproof membrane, tested to a 4.0 color fastness rating to keep its deep black finish through repeated washes. Wash separately before first use to minimize color bleed. Standard vs Extreme: This Standard sheet has breathable elastic black sides (non-waterproof) for a snug, regular-fitted-sheet feel with full waterproof protection on top. Want fully waterproof skirting and complete mattress coverage? See our Extreme range. Built for couples who want serious mattress protection without the plastic-bag feel of a typical waterproof mattress protector, this King waterproof fitted sheet shields your bed from oil, water-based, and silicone-based massage products with a sleek black design that looks and lays like a regular fitted sheet. The bonded TPU waterproof layer locks out spills, sweat, and stains across the entire top surface, while breathable elastic black sides keep the sheet snug on King mattresses up to 14 inches deep, with no bunching, sliding, or rustling. Whether you're reaching for it as a nuru massage sheet, a stain-proof bed sheet for an at-home spa session, or simply a waterproof intimacy sheet for everyday use, this oil-resistant bed sheet stays put session after session. Crafted from a durable blend of 95% polyester and 5% spandex with advanced TPU waterproof technology, our King waterproof mattress protector is hypoallergenic, machine washable, dryer safe, and tested to a 4.0 color fastness rating, so the deep black finish holds through repeated washes. Wash separately before first use to minimize any color bleed into other linens. A practical alternative to a basic king size mattress protector or king mattress pad, this 14'' deep pocket fitted sheet grips firmly on standard, hybrid, and pillow-top mattresses (designed for 72'' x 80'' King). Use it as a stand-alone black mattress protector for sensitive sleepers, or pair it with our massage powders, oils, and gels for a complete setup. Looking for full-coverage waterproof protection on the sides too? Our Extreme range uses the same construction with fully waterproof skirting for complete mattress coverage.
