Frequently asked questions
What pocket depth is considered 'extra thick' for a fitted sheet?
Extra thick fitted sheets typically have pockets of 15 inches or deeper. For very thick mattresses (18-24 inches), look for sheets with at least 18-inch pockets.
How do I measure my mattress depth to find the right sheet?
Measure from the top of the mattress down to the bottom, including any topper or pillow top. Add the depth of your mattress foundation if the sheet will cover it. Choose a sheet with a pocket depth at least 2 inches deeper than your measurement.
What type of material is best for thick mattress fitted sheets?
Cotton (especially percale or sateen) offers breathability and softness. Microfiber is budget-friendly and stretchy, ideal for deep pockets. For cooling, percale or Tencel is best.
Do fitted sheets with all-around elastic bands stay on better than those with only corner straps?
Yes, owners report that sheets with elastic that goes all around the fitted sheet stay in place better, especially on extra thick mattresses. Corner straps can slip off if the mattress is deep.
How often should I replace my fitted sheet?
Quality fitted sheets can last 2-3 years with proper care. If the elastic wears out or the sheet pills or thins, it's time to replace. Washing in cold water and low-heat drying extends life.
