If guests are allergic to feather and down, Hilton ® Hotels offer them a couple of alternatives. One of them is the Envirosleep ® Dream Surrender pillow. This pillow is filled with 100% hypoallergenic polyester cluster puffs. These clusters allow the pillow to stay lofty and help it maintain its support level throughout the night.
