We have enjoyed these sheets for a couple of washings now and they are still nice and thick. It is true that the first time you wash them their texture will change, but I think that is the "brushed" feel that they advertise. We've had a couple of sets of flannel sheets and these are just as good and thicker. They are a good quality for sheets that compare to slightly more expensive sheets that you might find at various retailers. The colors and design is fun too!
These sheets are very poor quality and are not worth the price. They have started pilling in less than a week of use. Now, anytime we sleep in them, we have little bits of the fabric all over us, including in our hair and on our faces. Not pleasant. It's a shame, because they are otherwise quite comfortable, but they are very poor quality and I don't expect they would last long given how fast they have started having problems.
