The wool layer that makes this Classic Natural Wool Mattress unique offers softness with a supportive feel. Wool improves your sleep quality all year round, keeping you warm in winter and cool in summer. Individually encased in hard-wearing fabric pockets, 2200 springs are nested into the heart of the mattress and move independently from one another to respond to your natural contours and movements during the night. Beautifully tailored in a luxurious Belgian damask fabric, the sumptuous fillings are held together by three rows of side stitching and traditional hand-tufting. This protects against wear and offers maximum durability. The addition of a hypo-allergenic layer works to protect your mattress from dust mites, creating a healthy sleeping environment.
