It sits like a fitted sheet with an elastic skirt, not a thick foam topper. What is Woolmark certification?Woolmark is the world's leading wool textile certification, guaranteeing the product contains 100% pure new wool that meets strict quality and performance standards. It's the gold standard for wool bedding authenticity. Does wool sleep hot?No — this is one of the most common misconceptions about wool. Wool is a natural thermoregulator: it wicks moisture away from your body and allows airflow, keeping you cool in summer and warm in winter. It outperforms most synthetic fills for temperature regulation. What's the difference between organic wool and regular wool?Organic wool comes from sheep raised without synthetic pesticides, hormones, or antibiotics, on land managed without synthetic fertilizers. It's better for the environment, the animals, and for people with chemical sensitivities. Can I machine wash it?Yes — it's fully machine washable on a gentle/wool cycle. Use a large-capacity or commercial washer for Queen and King sizes. Avoid bleach and fabric softener. Tumble dry low. Will it fit my deep mattress?The elastic skirt fits mattresses up to 15" deep on Queen and King sizes, and up to 13" on Twin, Double, and Twin-XL. If you have a mattress topper already on your bed, measure the combined height before ordering. Is wool hypoallergenic?Yes. Wool naturally resists dust mites, mildew, and mold without chemical treatments — making it one of the best choices for allergy and asthma sufferers. It's also naturally fire resistant. How does this compare to a synthetic mattress pad?Synthetic pads (polyester, microfibre) trap heat and moisture. Wool regulates temperature, wicks moisture, and is biodegradable. For anyone who sleeps hot or has sensitivities, wool is a significant upgrade over synthetic fills.
