A cushion assembly is the complete lower seat ready to bolt to the tracks, while an inner cushion or a cushion frame is a component used to rebuild one.
Cushions are replaced when the lower foam has flattened, when the frame has rusted through at the mounting points, or when a collision has distorted the pan. On vans and SUVs the rear cushion often includes the folding hinges, and those hinges wear out long before the upholstery does.
Order by position and by seat type. The driver and passenger cushions are usually mirror images with different part numbers, and a cushion for a power seat carries the motor mounting points that a manual cushion does not. Colour comes from the trim code, not from the name of the colour in the listing.
