CONVEYANCE SEAT

Provided is a conveyance seat capable of appropriately controlling the behavior of the pelvis (lumbar) of a seated occupant when an impact occurs, and thereby suppressing the generation of a compressive load on the spine of the seated occupant. This conveyance seat is provided with a seat cushion. The seat cushion has: a seat cushion frame; a cushion pad placed on the seat cushion frame; and a high-hardness portion provided below the cushion pad and higher in hardness than the material of the cushion pad. The high-hardness portion is disposed such that at least a part of the high-hardness portion overlaps a sinking suppression member in the vertical direction of the conveyance seat. The sinking suppression member is provided in the seat cushion frame or a vehicle body so that sinking of a seated occupant is suppressed. The sinking suppression member is disposed below the high-hardness portion.
