The image shows the backrest of an airplane seat with a blue seat cushion. The seat is upholstered in a dark blue fabric and has a small tray attached to it with a handle on the right side. The tray has a red button on it, which is likely used to adjust the height of the seat. The backrest is also blue and appears to be made of a similar fabric material. There is a small armrest on the left side of the image, and the seat is facing towards the right. The background shows the interior of the airplane, with other seats visible in the background.
