Bedding FAQ

Why cotton instead of waterproof protection?

Waterproof protectors use synthetic barriers (typically polyurethane) that completely block liquid penetration but also severely restrict breathability. For natural fibre mattresses filled with wool, cotton, cashmere, or horsehair, this trapped moisture and reduced air circulation undermines the very properties you’ve paid for. Cotton protection defends against the primary threats to mattress longevity (body oils, perspiration, skin cells, dust mites) whilst maintaining breathability. For most households without young children or specific medical needs, cotton offers superior daily protection without compromising sleep quality. If waterproofing is essential, we can recommend alternatives, but understand the trade-offs involved.

Will this fit my John Ryan mattress?

The 38cm skirt accommodates mattresses between 25-35cm deep, which covers our Origins and Artisan ranges when the protector stretches over the depth.  The full elastication helps secure the protector in place through the night.

Does quilted cotton change how my mattress feels?

The cotton fill adds subtle, barely perceptible cushioning. You’re not adding a thick mattress topper; rather, there’s gentle softness that many customers find enhances comfort without masking the support characteristics you’ve carefully selected. The quilting distributes fill evenly, preventing bunching or lumpiness. Most sleepers adapt within one or two nights and quickly forget the protector is even there.

How does anti-allergy treatment work?

The anti-allergy coating creates an environment hostile to dust mites and allergens without using harsh chemicals. It’s particularly beneficial for allergy sufferers or asthma patients who need cleaner sleep environments. Combined with regular washing (we recommend monthly for allergy-conscious households), this treatment significantly reduces allergen accumulation compared to unprotected mattresses.

How often should I wash this protector?

Monthly washing is ideal for maintaining hygiene and freshness. The cotton construction withstands regular laundering far better than some synthetic protectors that degrade quickly. Machine wash at 40°C, tumble dry on low heat or line dry, and refit whilst slightly damp for easiest application. Regular washing removes accumulated body oils and dust mites, keeping your sleep environment genuinely clean.

Will this protector make me sleep hot?

No. Pure cotton is one of the most breathable natural fibres available, permitting excellent air circulation and moisture wicking. Unlike waterproof protectors with synthetic barriers that trap heat noticeably, cotton maintains your mattress’s natural temperature regulation. Many customers report no perceptible temperature difference compared to sleeping without protection, which is precisely the point.

Can I use this with a mattress topper?

Yes, though measure your combined mattress and topper height to ensure it falls within the 25-35cm range the 38cm skirt accommodates. The protector goes directly on your mattress, with the topper placed on top of the protector. This arrangement protects both your mattress and the underside of your topper from contamination.

How does this compare to cheaper mattress protectors?

Budget protectors typically use thin synthetic fabrics with minimal or no fill, providing basic barrier protection without comfort enhancement. They often fit poorly on deep mattresses, shifting during the night and creating frustrating wrinkles. Our hotel-quality cotton construction offers genuine protection with added comfort, proper depth for handmade mattresses, and durability that justifies the modest additional cost. When protecting a mattress you’ve invested hundreds or thousands in, economising on protection makes little sense.

Is this noisy or crinkly?

Not at all. Pure cotton protectors are silent, unlike some waterproof protectors with plastic-feeling materials that rustle with every movement. You’ll hear nothing but your mattress’s natural quiet, which matters more than many people realise for undisturbed sleep.
