Can I use the four-piece set of 1.8 bed?
Sure, it's just that the sheets may be a little short, but it's not a big problem. The quilt cover depends on the size of your quilt core. My bed is 1.8. There are quilts of 1.5 and 1.8 at home, and the four-piece suit was bought accordingly. I bought two sets of four-piece suits in Heju.com last week, one for 1.5m and one for 1.8m, and I like their four-piece suits very much. It's of good quality and comfortable to cover. Compared with the quality, the price is not expensive at all.
