I always have 4 pillows on my bed, and my guest beds.  It's a pain trying to find a matching set of pillowcases.  Being able to get all 4 pillowcases with the set is a big plus to me!  This are very deep pockets that fit my Cal King pillowtop mattress so well that I don't have to re-tuck the corners every time I make the bed.  These sheets are soft and comfortable.  I good value for sure.
