PlushDeluxe Mattress Encasement — King 100% Waterproof Cotton Terry, All-Side Seal & Hypoallergenic

PlushDeluxe King Mattress Encasement is a 100% waterproof, soft cotton terry cover that fully seals all six sides of a mattress for liquid protection and allergen defense without changing mattress feel.

This mattress encasement combines a breathable waterproof membrane with a soft cotton terry surface so you keep your mattress dry, hygienic, and comfortable. The design uses a concealed zipper with a Velcro-secured flap for a snug, full-envelope fit that repels liquids, blocks dust mites and allergens, and machine-washes easily. It’s free from vinyl, PVC, and phthalates, ensuring a quiet, non-plastic sleep surface.

How does this encasement protect against spills and stains?

The PlushDeluxe encasement features a fully sealed, waterproof membrane that prevents liquids from passing through to the mattress core. Because it covers all six sides, fluid cannot seep into seams or edges—ideal for bedwetting, accidental spills, or perspiration.

• 100% waterproof barrier across the entire mattress surface and edges
• Sealed, fine invisible zipper plus Velcro flap prevents leakage
• Machine-washable for repeated protection after cleaning

Will the cover change how my mattress feels at night?

No—this encasement is crafted with a soft cotton terry outer layer that preserves the mattress’s original comfort and breathability. The waterproof membrane is engineered to be quiet and flexible so it doesn’t create a crinkly or rigid sleeping layer.

• Soft cotton terry surface maintains mattress texture and temperature
• Membrane designed to allow air circulation while repelling liquids
• Free from vinyl, PVC, and phthalates to avoid plastic sensations

How does it help with allergies and hygiene?

The encasement provides a physical barrier against dust mites, pet dander, and common allergens that collect in mattresses. Its hypoallergenic materials limit bacterial growth and make it easier to keep your sleep surface clean via regular washing.

• Hypoallergenic construction prevents allergen and mite penetration
• Breathable membrane discourages bacterial accumulation
• Machine-safe cleaning simplifies hygiene maintenance

Is the encasement secure and durable for everyday use?

The full-envelope design uses a fine, concealed zipper and a reinforced Velcro flap to hold the cover firmly in place over time. Built for frequent washing and daily wear, the materials are chosen for long-term durability without degrading the barrier performance.

• Invisible zipper with Velcro flap ensures a tight, full coverage seal
• Durable stitching withstands regular laundering cycles
• Designed to cover and protect all six mattress sides evenly
