The present disclosure provides cover systems for covering components of a cabin interior of a vehicle, such as an automobile, a train car, a bus, a boat, or an aircraft, among others. For instance, the cover systems may cover one or more of a seat and a floor, among others, of the cabin interior. The fabric cover systems may absorb or partially absorb one or more of low-frequency sounds, such as low-frequency noise emitted by an engine, and high-frequency sounds, among others. The fabric cover systems may absorb or partially absorb odor molecules. The fabric covering systems may include multiple layers. For instance, one of the layers may include activated carbon fibers. The activated carbon fibers may absorb or partially absorb one or more of sounds, liquids, and odors, among others.
