Difference between Japanese Futon Mattress and Western Futon Mattress

Understanding the difference between Japanese futon mattresses and western futon mattresses may be hard for people who have never used futon mattresses. Simply put, the major difference between these two types of futon mattresses lies in the thickness and flexibility.

Western mattresses have a thickness of about six inches or more, whereas japans mattresses have a thickness of two to four inches.
