Why Wool? Wool is one of nature's most effective temperature regulators. Each fiber can absorb up to 30% of its weight in moisture without feeling damp, pulling sweat away from your body and releasing it as vapor. The result: you stay dry and comfortable whether it's July or January. Wool is also naturally hypoallergenic and resistant to dust mites, mold, and mildew - no chemical treatments needed. Materials & Certifications Fill: 100% GOTS certified organic wool (no synthetic blending) Shell: 500-thread-count GOTS certified organic cotton sateen Certifications: GOTS (Global Organic Textile Standard) Free from: polyester, synthetic fibers, flame retardants, formaldehyde, chemical treatments Standard vs Deluxe: Which One Is Right for You? Standard Organic Wool Mattress Topper Best for sleepers who want a light layer of softness without significantly changing the feel of their current mattress. The Standard adds gentle cushioning and temperature regulation with less filling. Choose this if your mattress is already comfortable but needs fine-tuning - a touch more softness, better moisture wicking, or a cooler sleep surface. Deluxe Organic Wool Mattress Topper Best for sleepers who want a noticeable upgrade in plushness. The Deluxe uses a heavier wool fill for a deeper sense of surface comfort. Choose this if you want your mattress to feel generously luxurious and fluffy on top. Both variants share the same 500TC organic cotton sateen shell and GOTS certified organic wool fill - the difference is the amount of wool and the resulting thickness and level of plushness. How It Works on Your Bed Place the topper directly on your mattress, then put your fitted sheet over it as usual. The quilted construction keeps the wool evenly distributed and prevents shifting or bunching. The organic cotton sateen shell is smooth against your sheets preventing any friction or noise. Care Instructions Spot clean as needed. For a deeper clean, air out in direct sunlight - UV light naturally refreshes and sanitizes wool. Professional dry cleaning is recommended for full washing. Do not machine wash or tumble dry, as this can cause the wool fill to felt and clump. With proper care, organic wool maintains its loft and performance for years. Pair your wool topper with our matching organic comforter for a complete natural sleep system that regulates temperature from top to bottom.
