The Regency premium down-alternative pillow features an ultra-soft 300-thread-count cotton fabric. It’s specially engineered with Comfordry™, which keeps the pillow cool and dry by wicking away moisture for a more comfortable night’s sleep. NuAir™ fabrication, a tightly woven breathable allergen-barrier fabric, prevents dust mites, pet dander, pollen and other allergens from inhabiting the pillow. These luxurious pillows are filled with Duoloft™ down-alternative hypoallergenic fiberfill, which provides a silky-smooth sleep surface, all-seasons warmth, and serene down-like softness for a luxurious night’s sleep. The comforter is crafted and conditioned to feel like down for a silky-smooth surface. A two-inch gusset on all sides provides added loft, superior support and pliable softness that contours to your head and neck for proper alignment and comfort.
