Thread count refers to the number of threads (both horizontal and vertical) in one square inch of material. Generally speaking, the greater the number, the smoother, more durable the sheet. At one point thread count played a large part in what type of sheets sleepers bought, but it’s becoming more important to focus on the overall quality instead.

Knowing what types of bed sheets fit your needs can help you sleep better and prevent you from having to buy replacements every few months. When choosing your sheets, keep in mind what type of sleeper you are. Hot sleepers are better off with breathable, cooling sheets like cotton or linen, while cold sleepers should opt for something warmer like flannel. Also, consider how much they will be used and what type of people (or animals) will use them the most.
