The Sleep & Beyond certified organic wool pillow is firm yet supportive and delivers a dry, comfortable place to sleep. We did notice the wool aroma but it dissipates when aired out and you do become use to it. We would highly recommend this wool pillow for someone allergic to polyester fiber, down feathers or dust mites, or for those who have multiple chemical sensitivities. It is a safe and healthy choice for you and your family. Plus, you can rest assured no chemicals or harmful substances were used to make it and no animals were harmed in the process either.
