Add a layer of plush and full waterproof protection in one piece with the Cariloha Quilted Mattress Protector. The top is 100% viscose from bamboo in a quilted jacquard stripe over 100% down alternative batting, so it softens the mattress surface slightly while a TPU polyurethane layer blocks spills, sweat, and accidents on five sides, the top and all four sides. The stretch side panels are 85% viscose from bamboo and 15% spandex, with Corner Active Bands and a Perfect Bed Border elastic edge for a fitted-sheet style grip that stays in place. Cariloha describes the bamboo top as thermal regulating, breathable, and naturally resistant to dust mites, mold, and mildew, and the build is quiet with no crinkle. Machine wash cold, tumble dry low. Sized Twin XL at 38 by 80 inches, Queen at 60 by 80, and King at 76 by 80, it fits new mattresses and adjustable base setups alike.
