Single Ply Sheet Sets: The Grand 1500 Thread count Egyptian Cotton sheet sets. The highest thread count of Single Ply Sateen weave fabrics is one of the best high thread count sheets in today’s market. Comfort, quality and opulence set our luxury bedding in a class above the rest! These luxury sheets were made with quality in mind. We use the thinnest possible Egyptian cotton yarn woven in the most advanced weaving looms to create a true maser piece in bedding. The higher the thread count makes the challenge greater to still maintain softness and durability in such thick fabric, but we deployed the best resources to keep this as superior as possible.
