Why AC Coach Seats Have an Extra Layer: Here’s the Surprising Reason

Train travel in India comes with many small details that often go unnoticed. One curious feature that sparks questions among passengers is the extra layer found on AC coach seats . Have you ever wondered why your seat has a flap of material stitched halfway? Let’s uncover its purpose.

Social Media Sparks Passenger Curiosity

Recently, a train traveler posted a photo on Reddit’s r/indianrailways forum highlighting this extra flap. The user asked, “I’m travelling by train after a long time and wondering why this extra layer is given on the seat. Usually, such things have a purpose, but often people don’t know about them.”



The image showed a flap of rexine attached to the main seat fabric, stitched only halfway, leaving just enough space for passengers to slip their fingers underneath. This simple feature prompted a flood of curious responses online.

The Practical Purpose of the Extra Layer

The extra flap on AC coach seats is not decorative - it’s highly functional. Its primary purpose is to secure the bed sheets provided to passengers.

AC coaches typically provide two sheets and a blanket per passenger. One sheet is spread on the seat, and the corners can be tucked neatly under this flap. This prevents the sheet from slipping while passengers turn, sit, or lie down, ensuring a comfortable and tidy sleeping space.

What Travelers Had to Say

Many passengers admitted they had never understood the flap’s function. Some shared stories of sheets constantly sliding off during journeys, unaware that tucking them into the flap would solve the problem. Others found the revelation amusing, joking about all the times their sheets refused to stay in place.

This small but clever design feature shows how even tiny details in train travel have a practical purpose, making journeys more convenient and comfortable for passengers.
