I don’t need one of these devices. The person in front of me cannot recline because my knees are pressed into the back of the seat in front of me. That is what happens when you are 6-7. I’ve had someone page the flight attendant when they couldn’t recline and complain that their seat was broken. She looked back at me and told the person “No, it isn’t.”
Same here at 6’3”. I try and be considerate for those sitting around me - and keep my body parts within the width of my seat.
Had my knees banged more than once by folks in front hitting the recline button and then slamming the seat back.
On the second slam I usually say “Excuse me, but that’s my knees you’re hitting”.
When that happens there is not much room for that little serving tray, the back of the seat and my knees.
I have been in that exact position. I’m 6’4” and have had the person in front of me try to recline the seat into my knees which were already against the seat back. She also flagged down the flight attendant who asked me if they could recline their seat into my space. I asked the flight attendant for some oil so that I could feel more like a sardine in a can. She walked away without saying a word.
Ever try bulkheads?
This, of course, has nothing to do with airlines and reclining seats but all to do with the lack of civility in modern society. People throwing water at each other, refusing to let other recline the seats, it’s plain disgusting.
