Your pillow is as important to good sleep as your mattress, so don't settle for weak, unsupportive pillows. The Natura Cloud Contour Pillow features Natura Smart Wool fill which resists the shifting and clumping that occurs in synthetic and down pillows. Natura Smart Wool also resists mold, mildew and bacterial buildup while repelling dust mites, making the Cloud Contour the ideal pillow for allergy sufferers. Smart Wool also works to control temperature and humidity throughout the night by wicking away moisture for a dry, healthy sleep. The Cloud Contour also features a cervical roll for optimum neck support.
