What is the structure under the rear seats of a car?

[CarolineFitz]

Usually, it's the fuel tank and fuel pump. Below is relevant information about car seats: 1. Lifespan: If no particularly unexpected situations occur, car fabric seat covers should be removed and cleaned every six months, while genuine leather seat covers require frequent wiping. When cleaning, be sure not to use acidic liquids, as genuine leather seat covers undergo chemical treatment, and acidic cleaners may affect the seat's lifespan. 2. Seat Types: Car seats can be categorized by shape into split seats and bench seats; by function into fixed, removable, and adjustable seats; by passenger capacity into single, double, and multi-person seats. Based on usage performance, seats have evolved from the earliest fixed types to multi-functional power-adjustable seats, including air-cushion seats, electric seats, stereo sound seats, mental recovery seats, and even electronically adjustable seats. By material, they are divided into genuine leather seats and fabric seats. There are also seats designed for special uses, such as child seats and racing seats.
