Water Resistant Mattress Encasement King Size 15-18ft Deep Pocket

Our review of this king size mattress encasement concludes it is best for shoppers who want full, practical protection without a plasticky feel. The six-sided, fully enclosing design and heavy-duty zipper with a Velcro flap are the standouts, providing reliable bed bug and dust mite protection while the terry cotton exterior feels soft and quiet. The fused TPU membrane keeps liquids away from the mattress yet breathes enough to avoid trapping heat, so it fits households seeking waterproofing plus a natural-feeling cover.

Key Features

• Six-sided enclosure: Fully encases the mattress to block bed bugs and dust mites from every angle for comprehensive protection.
• Premium zipper: Advanced micro-zipper and patented 3X zipper flap lock the closure to prevent accidental openings and limit particle entry.
• Water-resistant TPU membrane: Fused waterproof layer stops spills and accidents from reaching the mattress while remaining breathable.
• Terry cotton surface: Soft, stretchable fabric gives a noiseless, comfortable sleeping surface without vinyl or PVC.
• 3M Scotchgard stain release: Added stain-resistant finish helps spills clean up more easily and reduces normal wear on the mattress.

Who It's For

This encasement is well suited for people who need full mattress protection against bed bugs, dust mites, and spills but prefer a soft, cotton-feel cover rather than a vinyl or PVC shell. It is a practical choice for families with children, those with allergies who want a sealed barrier, and anyone looking to extend mattress life with a breathable waterproof layer.

Shoppers seeking a lightweight, cool-feeling top layer only or those who need an ultra-thin, fitted mattress protector rather than a full encasement should look elsewhere; this product is designed for complete enclosure and protection, not just a mattress topper.
