Reaks King-size waterproof mattress protector fits mattresses up to 18" deep, uses 30% bamboo-derived rayon for cooling, and blocks liquids quietly without crinkling.

Designed to keep your mattress dry and comfortable, this fitted protector combines a breathable bamboo-rayon surface with a waterproof membrane that prevents spills from reaching the mattress. It slips on like a fitted sheet and stays secure with a stretch skirt, while remaining quiet and machine washable for easy care. Ideal for households that want protection without sacrificing temperature regulation or sleep quality.

How does the protector help keep my mattress dry?

The protector includes an upgraded waterproof membrane that creates a reliable barrier against liquids, protecting the mattress from spills, sweat, and accidents. The membrane is backed by a tightly woven surface to block seepage while maintaining a smooth feel under bedding.

• Waterproof membrane seals out liquids effectively.
• Layered construction prevents leaks without bulk.
• Machine-washable barrier remains functional after cleaning.

Will this protector make noise like plastic covers?

No — the Reaks design avoids stiff plastic layers that produce crinkling sounds. The materials are engineered to be quiet and flexible so you can move freely without disruptive rustling noises.

• Soft, flexible membrane reduces nighttime noise.
• Smooth bamboo-derived top layer improves quietness and comfort.
• Suitable for light sleepers who are disturbed by crinkling covers.

Does the bamboo-derived rayon actually help with cooling?

The protector's cover contains 30% rayon derived from bamboo and uses a channel-weave construction that encourages airflow. That structure helps dissipate body heat more efficiently than traditional synthetic covers, contributing to a cooler sleeping surface.

• 30% bamboo-derived rayon top layer for breathability.
• Channel-weave enhances ventilation across the sleep surface.
• Lightweight feel that supports temperature regulation without added warmth.

How do I care for and fit this 18" deep king protector?

The protector is a fitted style with a stretchy skirt that accommodates mattresses up to 18 inches deep, making it easy to put on and keep in place. It’s fully machine washable; use a gentle cycle and tumble dry at low temperature (up to 40°C) to preserve the materials and waterproof membrane.

• Fitted skirt stretches to fit up to 18" deep mattresses.
• Machine wash gentle cycle; tumble dry low (max 40°C).
• Durable construction designed to tolerate repeated washing.
