GRT California King Waterproof Mattress Protector — Quilted Breathable TPU Backing, OEKO-TEX

GRT California King Waterproof Mattress Protector is a quilted, breathable mattress pad with a TPU waterproof backing and OEKO-TEX certification that shields your Cal King mattress from spills, sweat, and stains while keeping sleep comfortable.

This fitted California King mattress pad combines a soft, quilted top with a vinyl-free waterproof membrane to protect your mattress without sacrificing comfort. The protector is OEKO-TEX Standard 100 certified, machine-washable, and designed to stay breathable and fluffy so you don’t feel hot or stiff while sleeping. It fits securely around Cal King mattresses with a deep, elasticized skirt that keeps the pad in place night after night.

How does this protector keep my mattress safe from spills?

The protector uses a premium TPU membrane lining that blocks liquids such as water, urine, and accidental spills from reaching the mattress core. Because the membrane is bonded beneath a quilted surface, it prevents leaks while remaining soft to the touch.

• TPU waterproof backing repels fluids without a noisy vinyl feel
• Quilted top layers absorb surface moisture and distribute it evenly
• Elastic fitted skirt seals around mattress edges to prevent seepage

Will the mattress pad feel hot or change the mattress comfort?

GRT designed the quilted cover to stay breathable and plush, preserving the original feel of your mattress. The protector adds a light, cushioned layer without the stiffness often associated with cheaper waterproof pads.

• Quilted fabric provides a soft, padded sleeping surface
• Breathable construction helps dissipate body heat for cooler nights
• Lightweight fill keeps cushioning but won’t significantly alter mattress firmness

Is the protector safe for family members with sensitive skin?

This mattress protector is OEKO-TEX Standard 100 certified, meaning it has been tested for harmful substances and meets recognized safety criteria. The vinyl-free TPU membrane is a suitable alternative for households that prefer non-vinyl waterproofing options.

• OEKO-TEX certification confirms textile safety for skin contact
• Vinyl-free membrane reduces exposure to PVC-based materials
• Gentle quilted surface is comfortable for children and older adults

How do I clean and care for the mattress protector?

The protector is machine-washable for easy maintenance; follow gentle cycle washing and tumble-dry on low or line-dry for best results. Regular washing removes sweat and allergens and preserves the membrane’s protective performance.

• Machine wash on gentle cycle with mild detergent
• Tumble-dry low or air-dry to protect the waterproof membrane
• Avoid bleach or high heat to maintain fabric and membrane integrity

It’s ideal for shoppers who prioritize certified textile safety, simple care, and a breathable, quiet waterproof barrier for a Cal King mattress.
