Protective comfort for split California King beds

The Kingnex Waterproof Quilted Mattress Protector Pad combines a soft, breathable top with a reliable waterproof layer on the back. Crafted with hollow micro polyester fill and a brushed microfiber surface, it delivers a cushioned, cozy feel while helping your mattress stay cool and dry through the night. Designed for a split California King, this set includes two Twin XL pieces (36x84 each) that work together for flexible support on adjustable bases.

Whether you’re navigating a busy household, sleeping with little ones, or sharing a bed with pets, the protector offers practical protection without sacrificing comfort. The top remains soft to the touch while the bottom layer guards against spills, sweat, and stains, helping prolong mattress life and preserve a fresh look over time.
