These sheets are wonderful!! They are definitely high quality! 
The fitted sheet actually is made to stay on. No low quality elastic, the pockets are deep & thick. My sheets always come up because I move my feet around at night, but these don’t budge. I am so pleased with them!
They are so soft also, a wonderful sleeping experience! 
The top sheet is also very nice. It appears to be two layers & not just one cheap layer like most. Very nice in warm weather! I highly recommend these to anyone that has trouble keeping their sheets on the bed & want luxurious comfort!
