Abstract
Disclosed is a vehicle seat that is capable of changing a property of S springs with a simple configuration and therefore improves a seating property by changing the property of the S spring in response to a physique of a passenger. In regard to a vehicle seatin which S springsare stretched in a seat cushion frame that supports a seat cushion on which the passenger sits, a restriction memberthat is detachably attached to each of the S springsand partially restricts an extensional deformation of the S springsis provided.
