There are so many types of bedsheets available that it is often overwhelming to choose the right ones for your needs. To decide what type of sheets to purchase, think about your temperature needs. If you live in a climate that is cold most of the year, flannel or jersey "t-shirt" sheets are soft and hold warmth well. In warmer areas, choosing high-thread count, 100 percent cotton sheets is a good idea for temperature control. If you want the best and it is within your budget, pure silk sheets are the gold standard for tensile strength and softness. It pays to research your choices before buying bedsheets.
