I am very picky when it comes to sheets and these are think and very soft but still cool enough. Not a think cheap material, but made with a very good quality.  I've washed them a few times and they hold the shape and softness. They are not pilly but perhaps because I use Tide pods unscented and a fabric softner.  I try to take them out of the dryer fast enough so I don't have to iron it, which wouldn't bother most people but I still do because I like my top sheet folded back with no wrinkles and to look like a catalog!
