The quality of bed sheets is often conveyed by the thread count—the number of threads per square inch of material. In general, the higher the thread count, the softer the sheet, but the weave and type of thread may affect the hand of the material so that a sheet with a lower thread count may actually be softer than one with a higher count. Yarn quality also plays a part in the look and feel of sheets, as finer yarns tend to create a finer sheet fabric. The ply also plays a role in how heavy the sheet feels. Ply represents how many fibers are twisted together as the sheet is being created. A 2 ply 300 thread count sheet will feel heavier than a single ply 600 thread count sheet.

Duvet covers often have buttons, ties, an envelope flap, or zipper as a closure to keep the insert enclosed. It should be noted that a Duvet is the insert that goes inside the Duvet Cover; usually comprised of down or a down alternative. When the insert and duvet cover are together, sometimes it is referred to as a Comforter. It is common for Duvet Covers to have finishing details like flanges or embroidery along the side and bottom edges only.

 Thread count is another important factor to consider when choosing  high-quality bedding.  300-count bedding is considered the highest quality, offering a balance of comfort and durability.  However, it's important to note that higher thread counts don't always guarantee better quality.  In addition to thread count, the type of fabric and weave must also be considered to ensure that the  high-quality bedding is to your liking.

In 1689, English diplomat, Paul Rycaut visited Hamburg in Germany where he first experienced sleeping under a duvet. He sent his friends back in England some bags of eiderdown with instructions on how to make their own duvets and he also tried to sell the duvets himself. Unfortunately for him, the British people were not keen to embrace this new concept. It was prohibitively expensive, so instead, they opted to carry on using the more affordable sheets and blankets.
