Linenspa Waterproof Mattress Protector King - 5-Sided Fitted, Breathable & Quiet

Linenspa’s 5-sided waterproof mattress protector is a fitted-sheet-style cover that shields the top and all four sides of a king mattress up to 14" with a soft, breathable, fully waterproof surface.

Keep your mattress looking and feeling new with a protector engineered for everyday life. This Linenspa protector uses AquaTight technology to block liquids and stains while preserving airflow and the original feel of your mattress. The brushed polyester surface is quiet and gentle against sheets, and elasticized corners hold the cover securely on mattresses up to 14 inches deep. When it needs freshening, it’s machine washable and dryer safe on low heat for easy care.

How does this protector keep liquids from reaching my mattress?

The protector combines a waterproof backing with fully wrapped sides to form an impermeable barrier that stops spills, sweat, and accidental moisture. The fitted design creates continuous coverage from top to edge so liquids cannot seep into seams or the mattress core.

• 100% waterproof backing using AquaTight technology
• Seam construction that covers the mattress top and all four sides
• Fitted-sheet style with elastic corners to prevent gaps
• Protects against stains, spills, and moisture penetration

Will it change the look, feel, or temperature of my bed?

This protector is designed to be low-profile and quiet so it won’t alter the comfort or sound of your mattress. The brushed polyester face feels smooth beneath sheets, and the breathable construction helps maintain airflow so you won’t notice added heat.

• Soft brushed polyester finish that stays quiet

How easy is it to put on, remove, and clean?
