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.
A bottom sheet, or fitted sheet, is the sheet with the elastic edge that fits over your mattress—hence the name bottom or fitted sheet. As today's mattresses have grown much thicker, it's important to check the measurements before buying a fitted sheet to make sure it will stretch all the way over your mattress.
While bed linen and bed sheets are often used interchangeably, they are actually two distinct types of bedding that serve different purposes. Bed sheets are the primary layer that goes directly on top of the mattress, while bed linen encompasses a range of additional bedding items such as duvet covers, pillowcases, and decorative blankets. Whether you prefer the crisp coolness of freshly laundered sheets or the luxurious feel of high-quality linen, there are plenty of options to help you create the perfect bed for a good night's sleep.
