Avoid leaving the futon damp for long periods, and do not keep it pressed in the same spot for days on end — this prevents localized sagging and protects the support layer. Regular airing, turning, and a weekly-washed cover are the key habits that extend its service life.
If you are comparing Japanese futon care with a conventional mattress, focus on airflow, dryness, regular turning, and the right cover; these habits help the shikibuton keep its shape and comfort.
