"Dicky-seat" is an outdated term for a small folding seat in the rear end of a carriage. Today, this seat is commonly referred to as a jump seat or a flip seat. The term "rumble seat" is also used for the same type of seat. This term originates from the sound made by the rattling of the seat while riding on bumpy roads. Another less common synonym for "dicky-seat" is the "mother-in-law seat," named for its placement behind the driver, reminiscent of an annoying relative often relegated to the backseat. Overall, while the term "dicky-seat" may be a thing of the past, there are several other descriptive and commonly used terms that refer to the same type of seat.
