Available only from Hammacher Schlemmer, this is the pillow filled with carefully hand-selected wool from the British Isles, renowned for naturally hypoallergenic properties that make it resistant to odor-causing bacteria. The pillow’s 100% polyester ball fiber tube core is surrounded by a lavender sheath, which is encased in 5" of 100% vacuum system ball wool. A 100% organic cotton case covers the entire pillow. Lightweight and breathable, the wool also regulates temperature and humidity to promote a good night's sleep by preventing overheating, and its structure provides loft without the flattening common to synthetic materials. 27 1/2" L x 20" W x 7 3/4" D.
