This soft, quiet mattress protector is made from quiet, ultra-thin material that is breathable and maintains a comfortable sleeping temperature. The LUCID mattress protector has a cozy Terry fabric top surface that does not change the feel or sound of the mattress while providing excellent top-of-mattress protection against liquids, dust mites and allergens. A thin, quiet polyurethane membrane repels liquids and fluids to protect your mattress and your mattress warranty from stains. Made of safe materials, this protector is safe for children and pets. This liquid-proof barrier has tiny pores that allow air to pass for breathability and a comfortable sleep temperature. Every night your body sheds millions of skin flakes and loses up to one liter of body fluid through your pores and mouth. Because they survive on dead skin cells and bodily fluids, up to 2 million dust mites can live in your unprotected mattress. Exposure to dust mites has been linked to the development of asthma in young children. Additionally, dust mites have been shown to be a leading cause of allergies and eczema. LUCID mattress protectors cut off the food supply to dust mites, making it impossible for them to survive. Fitted sheet-style mattress protector has a fully-elasticized skirt and deep pockets that keeps the protector tightly in place on mattresses depths up to 22 inches. Easy to put on and take off for laundering, this protector works great on extra-thick memory foam and pillow top mattresses. Machine washable keep your mattress clean and fresh by washing your sleep surface. Machine wash hot water. Tumble dry low. Do not bleach, iron or dry clean. 100% Waterproof Repels All Liquids Including Bodily Fluids Perspiration Urine And Accidental Spills Machine Washable Protection Noiseless And Comfortable Hypoallergenic Cotton Terry Surface And Polyurethane Backing Inhibits Allergy Causing Dust Mites And Bacteria From Living In Your Mattress Safe For Children And Pets Fully Elasticized Fitted Sheet Style With Deep Pockets Designed To Fit Mattresses Up To 22 Inches Deep Ultra Thin Design Is Breathable Quiet And Sleeps Cool Without Changing The Feel Of Your Mattress Twin Size Protector Measures 39x 75 15 Year Warranty Features: Breathable, Allergen Barrier, Waterproof, Washable, Hypoallergenic, Dust Mite Barrier, Bed Bug Blocker, Antimicrobial Bed Size: California King Measurements: 75 Length/Inches, 39 Width/Inches Mattress Depth: Up To 22 In Deep Base Material: 100% Polyurethane Filling Content: 100% Nofilling Care: Machine Wash, Tumble Dry Protection Level: Moderate Mattress Securing: Skirt Mattress Pads & Toppers Type: Mattress Protectors Country of Origin: Imported
