The invention discloses a method for preparing a seat cushion based on soft melamine foam. The method comprises the following steps: (1) selecting the soft melamine foam with F/M of 1.5-2.5:1 for hotpressing, softening and baking to obtain the pretreated soft melamine foam; and (2) preparing the seat cushion by using the pretreated soft melamine foam. The pretreatment method enables the soft melamine foam which is not suitable for manufacturing the seat cushion or has poor performance to have good comfort, support, fatigue resistance and fireproof performance, so that the soft melamine foam is used for manufacturing seat cushions of office seats, public seats, automobiles, ships, rail vehicles and the like, and is particularly suitable for manufacturing aircraft seat cushions requiring light weight; and the method can meet the requirement of industrial production, and is beneficial to large-scale manufacturing.
