Overview

Introducing the GRT Waterproof California King Mattress Protector, a thoughtfully engineered layer designed to balance comfort and protection. Built with 40% natural rayon from bamboo, this cover emphasizes breathability and a soft, skin-friendly feel that enhances your nightly rest without adding bulk.

Breathable comfort with bamboo rayon

  • 40% bamboo rayon delivers a gentle, silky touch that stays breathable against skin.
  • 3D air fabric features channels that encourage airflow, helping you stay cooler through the night.
  • Designed to be quiet and smooth, avoiding the crinkle noise common with some covers.
  • Skin-friendly materials aim to reduce irritation and promote everyday comfort.

Reliable waterproof protection

  • 100% waterproof performance backed by a dual-membrane construction to guard against liquids and perspiration.
  • Double membrane design helps preserve mattress integrity while preserving a comfortable sleeping surface.
  • The protector stays soft and cushioned under you, so there’s no harsh plastic feel at night.

Fit for every bed

  • Deep pocket design with a stretchy skirt fits mattresses from 8" up to 26" deep.
  • Perfect for households with kids, pets, allergies, or incontinence needs, providing versatility and peace of mind.

Durability and easy care

  • Machine washable and safe for low-temperature tumble dry, making maintenance simple.
  • Manufactured through a controlled process to maintain waterproof capability after repeated washes (even after many cycles).
  • Durable construction designed to hold up to daily use without sacrificing comfort.

Real-life use cases
