A futon is not like any other type of mattress. A futon needs extra love and care due to its many possibilities. Your futon is depending on you. When down or 'worn out', please remember to reshape your futon by flipping it over to reshape the filling. You will immediately sense a change when doing that habitually.
Futons do not tolerate water. In case of an incident please clean your futon with a damp cloth with a small amount of clear dishwashing soap. Do not rub but clean your futon by dapping the area from dirt. Finish your cleaning by using a clean and non-dyed cloth to dry out the area.
