Abstract: An assembly is provided with a first layer connected to a second layer to form a bladder, with the first layer defining a first aperture therethrough, and one of the first or second layers defining a second aperture therethough. The third layer is connected to the first layer and positioned between the first and second layers within the bladder. The third layer is movable between a first position covering the first aperture, and a second position spaced apart from the first aperture. A seat assembly is also provided.

Abstract: This disclosure relates to systems including massage subassemblies for a seat, such as a seat of an automobile. The massage subassemblies are configured to provide a relatively intense massage. In an example, a system includes a first source of fluid, and a first bladder fluidly coupled to the first source of fluid and configured to be selectively inflated with the first source of fluid. The example system further includes a second source of fluid and a second bladder fluidly coupled to the second source of fluid and configured to be selectively inflated with the second source of fluid. Further, in the example, the second bladder projects from a surface of the first bladder, and the second bladder is fluidly isolated from the first bladder.
