The vehicle set is designed to provide the driver and the passenger with as much comfort as possible, while ensuring that it will keep them upright and awake. The purpose of the car seat is to be comfortable enough to sit on for a few hours, but not too comfortable to make you fall asleep. The seat is made using various kinds of foam, and is them covered using a seat cover. The seat cover is made from different materials, some are covered with normal fabric, while others are covered with leather. The front part of any vehicle carries two seats, these are the drivers seat, and the passenger seat. These seats are not connected, and are divided by an armrest, in most vehicles. These seats are separate to ensure that the driver is not disturbed. There are a few older models which feature a full length front seat, but that soon changed and now majority vehicles feature two single front vehicle seats.
