for 530TC Cotton Split Flex Top King White
The bottom sheet never did fit the split top sleep number bed properly (sleep number fits better). After washing and following directions it falls even shorter on sides and top to bottom than the Sleep Number sheets. I only used the Quahog sheets 4 times in a year, rather put up with the sheets I bought from Sleep Number! If you own a Sleep Number bed, Split Top Adjustable king, stay with Sleep number sheets, they are better while not perfect!!
