Accurate descriptions. These sheets were 15 inches deep instead of 13 inches deep as stated on the website. My mattress is not thick and the sheets bunch up if they don't fit properly. (It does not make for a good sleeping experience!) I have had a great deal of trouble trying to find sheets for a 12 in deep mattress. The elastic was not very wide and did not seem very strong either, so my guess is this would be stretched out rather quickly. Extremely disappointed!!!
