And many old people like this kind of sureness because quilts are getting heavier and heavier. However, it is bulky and airtight, and cotton needs to be "bounced" frequently, so it is easy to get wet in hot and humid areas in the south. If it is not well preserved, it will smell musty when it is taken out the next winter. Not suitable for people: people with chronic respiratory diseases, hypertension, heart disease and poor blood circulation.
