Three-piece set: bed sheet, pillowcase, four-piece set, one extra bedspread, five-piece set and one more quilt cover. A six-piece suit or a seven-piece suit will have one or two cushions. There will be more pillows and double pillowcases in the 89-piece set, which will be distributed by the manufacturer. Please consult the sales staff to buy according to their own needs.
I suggest the following. If it's for your own use, three sets will be enough. If you are very particular, you can add a bedspread, and the rest is unnecessary.
