These felt way too light to be a Queen sheet set in the package but they fit. The fitted sheet is actually about 2" deeper than our mattress (mattress is 14") so we were able to tuck them down around the sides which is nice, but also gives the sheets a lossness which might get frustrating as we both toss and turn a lot.They seem kind of thin, but they washed up great out of the package and warm up quickly when you get in bed during a Midwest winter. Time will tell how they do in summer. My partner is a hot sleeper so hopefully they keep him cool like our other microfiber sheet set.I love the pattern, not childlike or astrological, so good for science-minded household.
