Aller-Ease Zippered Mattress Protector King, White — Ultimate Allergy Barrier, Waterproof, Cotton-Top

From the best-selling AllerEase allergy bedding line, the Ultimate zippered protector combines a quiet cotton top with a waterproof backing and a fully enclosed zipper design to keep dust mites, spills, and allergens out of your mattress.

How does it prevent allergens and dust mites from reaching my mattress?

The Ultimate features a full zip enclosure and tightly constructed seams that create a continuous barrier around the mattress surface and sides. This design limits the migration of microscopic particles and pests into the mattress interior.

• zip-around closure seals the mattress completely
• specialized seams reduce entry points for allergens
• dense fabric layers provide an effective physical barrier

Will the waterproof layer change the feel or make noise during sleep?

The protector is finished with a soft cotton top that preserves the natural surface feel while hiding the quiet waterproof membrane beneath. AllerEase uses materials and construction that minimize crinkle and maintain the bed’s comfort so you still sleep on a familiar surface.

• quiet cotton outer layer for a natural touch
• waterproof backing protects from spills without stiffness
• temperature-balancing finish wicks moisture for dryer sleep

How do I care for the protector and will washing affect the fit?

This mattress cover is machine washable and designed to stay effective after repeated laundering when cared for according to the instructions. The elasticized corners and FlexFit design maintain a snug fit on mattresses of common depths even after washing and drying.

• machine wash hot; use non-chlorine bleach when needed
• tumble dry low and remove promptly to avoid damage
• fits mattresses up to 15" deep on queen and king, 12" on twin/full

What makes this protector a long-term value?

Built from premium materials with reinforced seams and a dependable zipper, the Ultimate is intended to protect the mattress from stains and wear that shorten mattress life. AllerEase backs the product with a lifetime warranty, reflecting confidence in its durability and offering ongoing value.
