Definitely fit my super, extra deep mattress (22") with some room to spare. Almost every other "extra deep" pockets that claim they will fit have not and end up popping off during the middle of the night. These are super soft and washed well - after reading the other reviews, I decided not to dry them with high heat in case of shrinkage - worked well on low for a bit longer - but since these were pricey - it was worth the caution. The extra set of pillowcases was great as we use 4 pillows on our King sized bed and would like to get another set.
