Where is the button to adjust the seat on a bus?

[McKai]

Button is located on the left or right side of the seat cushion inside the bus, or next to the armrest. Here is relevant information: 1. Adjustment angle: The principle of seat adjustment ultimately depends on the comfortable sitting angle for the human body. Each person's height and weight are different, so the most important aspects during actual adjustment are the angles of the back, elbow joint, and knee joint. 2. Aisle adjustment: For bus seats next to the aisle, the left and right buttons on the armrest adjust the seat's lateral movement, allowing the seat next to the aisle to be adjusted towards the aisle, increasing the width between seats.
