About this item

• FOR 2-4" THIN MATTRESSES ONLY:This cover is designed for thin floor mattresses up to 4" thick – shikibuton, tatami, camping pads, and folding guest beds. If your mattress is thicker than 4", please do NOT order.
• SIZE GUIDE – Match Your Mattress: Cut slightly larger than standard floor sizes for easy zipper. Choose by mattress: Cover 43"x83" (Twin) fits 39"x80" (Twin); 57"x83" (Full) fits 54"x80" (Full); 63"x83" (Queen) fits 60"x80" (Queen).
• Why We Cut Extra 3-4": Cotton naturally shrinks after the first wash. That's why we cut covers 3-4" larger – to compensate, ensure easy zipper, and prevent seam strain. After washing, it fits perfectly. Best: cold wash & line dry.
• 40s Cotton – Softer Over Time: Premium 40s combed cotton feels crisp & cool at first – normal. It softens with each wash, no pilling or shape loss. Unlike cheap synthetics, our cotton breathes, wicks moisture, and gets gentler over time.
• Lightweight & Washable – For Home, Camping & Travel: Easy to fold, machine washable, and quick-drying. Breathable cotton keeps you comfortable year-round and protects against dust and spills. Machine wash COLD only, line dry.
