In the video, a man is seen sitting in the back seat of a car. He is wearing a white shirt and has his hand on the armrest of the car seat. The man then opens the armrest, revealing a storage compartment. He proceeds to demonstrate how the armrest can be folded down to create more space. The car seat is gray, and the interior of the car is visible in the background. The man's actions are deliberate and clear, making it easy to understand how the armrest works.
