The “four-piece” usually refers to the four piece bedding set in people’s daily life. As the name suggests, it is a bedding made up of four kits. The necessary elements are a pair of pillowcases, a quilt cover, a bed sheet (sheets) . or a bed skirt (bed skirt).
There are the following types of bedding:
1. Four sets of bed mattresses (1 mattress, 1 quilt cover, 2 short pillowcases);
2, four sets of sheets (1 bed sheet, 1 quilt cover, 2 short pillowcases);
3, four sets of bedspreads (1 bed cover, 1 quilt cover, 2 short pillowcases);
4, four sets of bed skirts (the same as the four sets of bedspreads, just replace the bed cover with a bed skirt, and five sets of one more long pillowcase).
The four-piece set that people often say is: two single pillowcases + one quilt cover + one bed sheet. The frequency used is also relatively high.
