Description

Designed to simplify bedtime while keeping your mattress protected, the Coolflex® 2-in-1 Waterproof Mattress Protector & Fitted Sheet combines everyday comfort with reliable defence. Acting as both a fitted sheet and a mattress protector, it’s the only layer you need between you and your mattress for a smoother, more hygienic sleep.

Soft, breathable comfort night after night

The gentle cotton blend sleep surface feels soft and inviting, helping you settle into a comfortable night’s sleep without compromising breathability. Unlike traditional protectors, it’s designed to feel just like a fitted sheet, so comfort always comes first.

Waterproof protection with added hygiene

A discreet waterproof layer helps protect your mattress from spills, stains, and everyday accidents, extending its lifespan and keeping it cleaner for longer. Enhanced with AgCi anti-microbial treatment, the fabric actively helps defend against bacteria for a fresher sleeping environment.

Quiet, practical, and easy to care for

Crafted from rustle-free fabric, the Coolflex® protector stays quiet and unobtrusive as you move, so nothing disturbs your sleep. The deep 38cm skirt ensures a secure fit on deeper mattresses, while machine washability at 60°C makes maintaining freshness simple and convenient.
