Is Thread Count That Important?

Yes and no. Thread count is often used as a barometer of the bed sheets’ smoothness and durability. However, this measurement—which should refer to the number of threads woven into a square inch of fabric—isn’t always reliable. High thread count is a factor, but the type of cotton can be more significant.

What’s The Best-Quality Cotton?

Cotton is the best material for bed sheets. Top of the line is 100 percent Egyptian cotton. Second best is 100 percent pima cotton, also known by the trademarked name Supima. If a label says simply, “100 percent cotton,” assume it’s American upland cotton, a rougher, less expensive variety. Egyptian cotton’s long fibers produce sheets that are thin and sumptuous, yet extremely strong and long-lasting. The shorter fibers of upland cotton, by contrast, can poke out of the weave, leading to a coarser, weaker fabric. Pima cotton is also soft and less likely to pill than upland cotton. You can find a good queen set made of pima for less than $200. If you want the best, invest about $500 in an Egyptian-cotton set in percale or sateen—both clean, classic weaves.

What’s Better: Percale or Sateen?

Neither. It’s a matter of taste. Percale is a plain, matte weave that has a crisp, cool feel, so it may be sensible for people who tend to overheat when they sleep. Sateen is slightly heavier and very soft, with a lustrous, smooth finish that’s almost satiny. If you’re not sure which you prefer, look for fabric swatches on display for a touch test.

Cheaper Option For Kids or a Spare Set

A cotton-polyester blend, often marketed as “easy care,” is a smart choice for children since it withstands frequent washings well. A little poly is all you need—a 90/10 blend is durable, looks crisp right out of the dryer, and is still soft and cozy. Don’t go above 30 percent synthetic: The sheets won’t feel great and could generate heat.
