What kind of quilt is suitable for weather around 20 degrees?

I think it is better to cover ordinary cups with a thicker quilt in summer. In this case, it is warm and cool. Sleep soundly. I prefer this one. It's usually like summer. Turn on the cold air conditioner and cover with a thick quilt, haha. It feels so good.
