Bedsheets, quilt covers and pillowcases are all AB designs, and fluffy bedding sets are added.

The AB version of the four-piece suit means that the bed sheet, quilt cover and pillowcase are all AB version designs. This design is to design the front of the bed sheet, quilt cover and pillowcase in one style and the back in another style. Adding fluff can increase the warmth and comfort of bedding, especially in cold seasons.
