The term "back seats" typically refers to the space located in the rear part of a vehicle cabin, which is mainly used for seating. The antonyms for the phrase "back seats" would be "front seats" or "driver seats," denoting the area in the front part of the vehicle designed for the driver and front passenger to sit. The front seats generally have more visibility, comfort, and ease of access. These seats usually provide better safety features such as airbags, seatbelts, and other modern technology that ensures comfort and safety while driving. Thus, while the back seats provide extra seating or storage space, the front seats remain an essential part of every vehicle.
