The J. New York Regency overstuffed mattress topper adds an additional layer of cloud-like comfort to your mattress for an incredible sleep experience. The plush 300-thread-count cotton top mattress topper features Comfordry™ technology which helps keep your sleep surface cool and dry by wicking away moisture for a more comfortable night’s sleep. Also featuring NuAir™, an allergen-barrier fabric to prevent dust mites, pet dander, pollen and other allergens from penetrating the bedding. The topper is filled with down-like hypoallergenic fiberfill which provides superior support and a silky-smooth surface. The mattress topper is box quilted to prevent fiber shifting and the comforter is crafted with a two-inch gusset on all sides for added loft, support, and breathability. The four-way deep pocket stretch skirt can fit a mattress up to 21 inches.
