Buy the best! Buy USA! Unlike almost all other companies that “produce” bedding, SheetWorld has always been and remains committed to producing all of our own products in our own US based factories. We only carry the highest grade 100% cotton fabrics that are soft, durable, natural, hypoallergenic, and comfortable. The silky feeling cotton will give you that cool and calm sleep you have been craving for years.
