SOLUTION: A method for producing the fiber cushioning material comprises the following process: a web is prepared by blending inelastic crimped staple fibers with thermoadhesive staple fibers whose surfaces are provided with a thermofusible component consisting of a low-melting polymer lower in melting point than a polymer constituting the inelastic crimped staple fibers by 25°C or greater so as to be (90:10) to (30:70) in the weight ratio of the inelastic crimped staple fibers to the thermoadhesive staple fibers, provided that the inelastic crimped staple fibers are arranged in the web in such a way as to meet the relationship: T/H≥1.5 (wherein, T is the total count of the inelastic crimped staple fibers arranged in parallel to the thickness direction of the fiber cushioning material, and H is the total count of the inelastic crimped staple fibers arranged perpendicularly to the thickness direction of the fiber cushioning material). Thereafter, the mutual intersection points of the thermoadhesive staple fibers and/or the intersection points of the thermoadhesive staple fibers with the inelastic crimped staple fibers are thermofused to obtain a fiber cushioning material, which is then subjected to compressive treatment in the thickness direction at least once with a compression percentage of 25-95%, in the following or a separate step.
