Frequently asked questions
What makes a wool mattress protector better than synthetic ones?
Wool offers natural breathability, moisture wicking, and temperature regulation, which helps prevent overheating. It's also hypoallergenic and biodegradable, making it more eco-friendly than polyester or vinyl protectors.
Are wool mattress protectors truly waterproof?
Yes, most use a waterproof membrane (often polyurethane or TPU) laminated to the wool fabric. This blocks liquids while allowing vapor to pass through, but effectiveness can vary by brand.
How do I clean a wool mattress protector with waterproof backing?
Most are machine washable on a gentle cycle with mild detergent. Avoid bleach and high heat. Always check the care label; some may require air drying to preserve the waterproof layer.
Will a wool protector make my mattress feel hotter?
Wool is naturally breathable and helps regulate temperature. Owners commonly report that wool protects sleep cooler than synthetic alternatives, though some may still trap heat if the waterproof layer is less permeable.
What certifications should I look for in a wool mattress protector?
Look for GOTS or Oeko-Tex Standard 100 for organic and chemical-free wool. For waterproofing, ensure the membrane is free from PVC and phthalates. Some also have additional CertiPUR-US certification for foam components.
