1, there is nothing to say, just buy one and buy another. It's just that in some places, buying a pair of pillows is a good sign. If you are single, there is also a saying, that is, buy pillows and even numbers, and prepare a pillow for your other half, so that you can find the other half quickly.

2. If you get married and buy a four-piece suit, then you need to choose an even number of pillows. After all, two people share the same bed, so we must prepare two pillows, which means that they will never be separated. Only by choosing two pillows can we meet the daily use needs. In addition, it is best to choose a big red pillow for marriage, which is better with mattresses and sheets, and the overall aesthetic effect will be better.

3. If you prepare a pillow for your child, you only need to buy one, regardless of other issues. At this time, generally speaking, according to children's preferences, cartoon pillows are more popular with children, thus falling in love with sleep.

In daily life, it is more troublesome to clean the pillow. At this time, you can choose to put a pillowcase on the pillow. In the later use process, just remove the pillowcase and clean it. In addition, if you are tired of looking at pillowcases, you can also choose a new pillowcase, which is very cheap.
