Amazon Basics Zippered Waterproof Mattress Encasement — King

Overview

Meet the Amazon Basics Zippered Waterproof Mattress Encasement for King beds—an everyday layer that blends protection, comfort, and easy care. Engineered to fit standard king mattresses, it fully envelops the surface with a secure zipper, delivering a clean, barrier-style sleeping environment without adding bulk.

360‑Degree Encasement for Comprehensive Coverage

The complete encasement uses a 360-degree zipper to seal the mattress from all sides. This design creates a dependable shield against common household irritants and allows you to rest with a sense of containment and cleanliness.

Key benefits:

• All-around protection against allergens like dust mites and bed bugs.
• Flexible, durable fit with reinforced seams for long‑lasting use.

Waterproof Protection You Can Rely On

The 100% waterproof barrier guards the surface from spills, accidents, and liquid damage. While it may help limit moisture exposure, it is not a stain‑removal solution. It can make cleanup quicker and help keep the mattress surface looking fresh.

Why this matters:

• Ideal for households with kids, pets, or high‑traffic sleeping spaces.
• Helps maintain a cleaner surface by preventing liquids from seeping into the core.

Comfort, Breathability & Quietness

Made from flexible polyester fabric with a polyurethane backing, the encasement offers breathable, low‑noise performance. It adds a protective layer without changing the texture or feel of your mattress.

Care, Durability & Easy Maintenance

Designed for busy homes, this encasement is machine washable and dryer‑friendly. It holds up well to repeated washes while preserving its protective properties.

• Machine washable for straightforward upkeep.
• Maintains shape and protective performance over time.

Size Fit & Durability

With a size‑specific fit and a 12‑inch pocket depth, plus reinforced seams, the product is built for longevity. A snug, secure fit helps reduce shifting and maintains full coverage night after night.

Sustainability

Crafted with 71% Global Recycled Standard (GRS) certified recycled post‑consumer polyester, this encasement reflects a commitment to recycled materials in everyday essentials.

Use Scenarios

Think guest rooms, family movie nights, or seasonal spaces where a tidy, low‑maintenance sleep area is helpful. This encasement offers a practical, protective layer that complements a clean mattress surface.
