Hanherry Cooling Waterproof Mattress Protector King Size — Deep Pocket 8"–21", Breathable 3D Air Fabric

Hanherry Cooling Waterproof Mattress Protector is a king-size mattress cover that combines cooling yarn, 3D air fabric and a noiseless waterproof TPU backing to protect mattresses up to 21 inches deep while keeping sleep breathable and comfortable.

Keep your mattress clean, cool and comfortable with a protector designed for modern beds. This Hanherry mattress pad uses cooling yarn to help move heat away from the body, a soft 3D air fabric surface for added comfort, and a breathable TPU backing that blocks liquids without trapping moisture. Built with deep elastic pockets, it secures over mattress heights commonly used in toppers, pillow-top designs and hybrid constructions.

How does this protector help me sleep cooler?

The surface is woven with cooling yarn that helps dissipate body heat and encourages airflow across the sleep surface. That cooling effect is combined with the 3D air fabric structure to reduce hot spots without sacrificing softness.

• Cooling yarn moves heat away from skin for a cooler feel.
• 3D air fabric increases breathability and adds plushness.
• Open-knit construction helps air circulate under covers.

Will it actually stop spills and accidents without sounding crinkly?

The protector’s backing is made from 100% TPU, which forms a waterproof barrier that repels liquids while remaining flexible and quiet. Unlike older vinyl or PVC layers, TPU is engineered to allow air exchange and minimize noise during movement.

• 100% waterproof TPU backing blocks liquids and stains.
• TPU is breathable and noiseless compared with vinyl options.
• Seam construction reduces leakage points for better protection.

Will it fit my mattress and stay in place all night?

The protector includes an extra-deep pocket and strong elastic edging to fit mattresses from 8 inches up to 21 inches deep, securing the cover to oversized and pillow-top mattresses. The stretch design prevents shifting and bunching so your sheets remain smooth.

• Deep pockets accommodate mattresses up to 21 inches tall.
• Elastic skirt grips edges to reduce movement and slipping.
• Flat seams and tailored fit maintain a neat bed profile.

How do I care for the protector and keep it performing?

Maintenance is simple: machine wash on a gentle cycle and tumble dry low or air dry to preserve the cooling yarn and TPU backing. Avoid bleach or high heat, which can shorten material life; follow included care tags for best results.

• Machine wash gentle; tumble dry low or air dry recommended.
• Avoid bleach and high-heat drying to protect TPU and fibers.
• Inspect seams after washing; resecuring elastic if needed maintains fit.
