The invention belongs to the field of cushions, and relates to a modified hollow polymer microsphere, a polymer cushion and a preparation method of the polymer cushion. The modified hollow polymer microsphere comprises a hollow microsphere main body of which the surface is modified with a silane coupling agent, and a reinforcing layer and a fluorine-containing polymer layer which are sequentially coated on the surface of the hollow microsphere main body. The key point of the invention is that the hollow polymer microspheres are used for replacing a traditional air bag structure for the buffer cushion, and the hollow polymer microspheres are designed into a specific structure comprising a hollow microsphere main body, and a reinforcing layer and a fluorine-containing polymer layer which are sequentially coated on the surface of the hollow microsphere main body; meanwhile, the surface of the hollow microsphere main body is modified with the silane coupling agent, and the hollow microsphere main body has specifi
