The Knee Defender is a device that airplane passengers can place on the struts that support their drop-down airplane seat tray table to limit the extent to which the seat directly in front of them can be reclined.[1] The device was invented by Ira Goldman, and it was first sold to the public in 2003.[2][3] While the legality of using these devices on commercial flights is unclear, some carriers such as United, Qantas, Virgin, Jetstar, and some other major airlines have banned the use of this or similar devices on their flights.[4][5][6] The manufacturer of the device advises purchasers of the device to: "Be courteous. Do not hog space. Listen to the flight crew."
