Aller-Ease Zippered Mattress Protector Full — Ultimate Allergy & Waterproof, Breathable Comfort

Aller-Ease Ultimate Zippered Mattress Protector (Full) is a fully encasing, breathable, waterproof barrier that keeps dust, pollen, pet dander, and spills out of your mattress while maintaining temperature comfort.

From the top-selling allergy bedding brand, this full-size zippered protector combines a soft cotton-like sleeping surface with a tight, engineered barrier layer to block common household allergens and liquids. Designed with reinforced seams, a full perimeter zipper, and a temperature-regulating finish, it protects the mattress interior without creating the crinkly noise or stiffness of older covers. Machine washable and backed by a lifetime limited warranty, it’s intended to extend mattress life and improve sleep hygiene.

How does this protector block allergens and tiny particles?

The Aller-Ease Ultimate uses a densely woven, purpose-built fabric that acts as a physical barrier, preventing up to 99.9% of dust, pollen, and pet dander from entering the mattress. Expert construction—sewn seams and a full zipper—creates a continuous protective layer that is difficult for particles to penetrate.

• Tightly woven fabric engineered to stop microscopic particles
• Full encasement with a zipper for edge-to-edge protection
• Specialized seams that minimize gaps or weak points
• Recommended by allergists for reducing mattress pollutant buildup

Will it keep liquids and stains from reaching my mattress?

This protector features a waterproof inner layer that prevents spills and accidents from soaking into the mattress core. The waterproofing is combined with a soft outer surface so protection doesn’t come at the expense of comfort.

• Waterproof barrier blocks liquids, helping prevent stains and odors
• Durable construction suited for kids, pets, and nightly use
• Machine washable for easy cleanup and stain control

Does it affect how warm or cool I sleep?

Aller-Ease integrates a temperature-balancing finish similar to materials used in performance apparel so it holds heat when you’re cold and releases it when you’re warm. The result is a more consistent sleep surface temperature without the clammy feel of some waterproof protectors.

• Temperature-balancing fabric for adaptive comfort night to night
• Breathable layers that help moisture evaporation
• Soft, cotton-like top for a pleasant sleep touch

How will it fit and care for my mattress?

The protector employs Aller-Ease’s FlexFit technology to stretch smoothly over mattress corners and stay quietly in place. It’s designed for simple maintenance—machine washable and dryer-safe—so you can keep a clean sleep surface with minimal effort.

• FlexFit elastic design for a snug, quiet fit on full-size mattresses
• Machine washable and durable for frequent laundering
• Lifetime limited warranty for long-term peace of mind
