Here is a new invention that many air travelers have longed for. The Knee Defender is a piece of plastic that attaches to the tray table of the seat in front of you, and once attached limits the degree to which the person in front of you can recline their seat. Some people feel quite strongly about this; in response to this travel column, one person said:
Personally, I’m 6’2", so I feel the pain of those who have had their knees bashed. I’d rather talk to the person in front of me and politely ask that they not fully recline, but as a backup plan for when that doesn’t work I think I’ll be buying one of these. How say the Teeming Millions?
