A method for producing a mattress, the mattress including

• a tactile layer that is positioned on an upper side in use, and
• a cushion layer that is positioned on a lower side in use,
• the tactile layer and the cushion layer containing a first elastic body and a second elastic body, respectively, the first elastic body and the second elastic body include a filament three-dimensional assembly,
• the first elastic body having a thickness of 8 mm or more and 30 mm or less,
• the second elastic body having a thickness of 50 mm or more and 250 mm or less,
• wherein when a circular plate with a diameter of 150 mm is placed on an upper surface of the first elastic body, and a load required to move the circular plate downward by 7.5 mm is defined as a resiliency of the first elastic body,
• the first elastic body has a resiliency of 10 N or more and 80 N or less,
• the second elastic body has a resiliency of 100 N or more and 200 N or less, the method comprising:
• selecting, as the first elastic body, an elastic body that provides a difference in sinking displacement between a shoulder and a buttocks of 0 mm or more and 5 mm or less when a user lies in a spine position on the first elastic body.
