I have had to sit on those seats for about a dozen flights. I really dislike them. The controls are too complicated (when all the buttons work) and it takes way too long to adjust them, and when the adjustments are optimized, they are still very uncomfortable - I keep sliding out of the seat too, and its way too flat for my body. Torture devices is what they are.
Bring back the old seats. At least they were comfortable and it wasn't too much trouble to put the legrest down so the guy next to you can get out to go to the john.
Don't get me started on the new entertainment system....
