Fitted sheet does not have enough elasticity to stay on mattress. My husband will have this thing off by morning on his side. The pillow cases do not fit king pillows after being washed. The ends of my pillows are hanging out the end. 
The feel of the sheets are really nice though, so I am bummed these are not a match. Was hoping these would serve as a primary sheet set but they are now deemed as a back-up in the case my kids have an accident. And the pillow cases, for a king bed, are more for a queen or twin. Other rooms will adopt these as the fabric is comfortable.
