I like the current seats, probably due to their relatively reclined position and the fact they are slimline. I am 190 and still can stretch my legs under the seat in front of me, that is crucial for me. I don't like upright seats like of AirAsia (which, admittedly, also have lower pitch). Since also the new 737-800s will have 186 seats like the current ones, I wonder why KLM has chosen seats that have the drawbacks reported (apart from the advantage of the better headrests and USB ports).
