Do remember that the best type of material for bed sheets differs per person depending on a number of factors, including things like whether you sleep hot or cold if you're looking for an easy-to-clean material or a long-lasting material.

 To choose bedsheets that won't pill, you have to pay attention to the quality of the fabric as well as the construction of the sheet.  Look for bedsheets with a high thread count, as this indicates a tighter weave and helps prevent pilling.  Also consider the ply count of the fabric, which refers to the number of yarns that are twisted together to form a single thread.  Single-layer fabrics are generally smoother and less prone to pilling than multi-layer fabrics.
