Sat right at the very back. Arm rest doesn't fold away so shoulder room restricted. I'm a large frame but my wife isn't and she also found this the most cramped uncomfortably seating we've ever experienced on any airline in many years of travel (I've been transatlantic a dozen times in the last 10 years). I'm just thankful the man in front of me didn't recline his seat. He'd have been balanced on my knees if he had! I hope more people complain so KLM might change things.

Old half-cargo 747 from JFK to AMS. Absolutely absurd seat pitch for long-haul international. I'm of average height and pretty skinny, and I couldn't for the life of me even get out of my row when someone ahead of me had their seat reclined. Getting into and out of the seats was a production! Even in the upright position, the space between rows is so cramped, one needs to cling to the row ahead of you to avoid toppling over backwards while trying to sidle into your seat. The cushions were rather uncomfortable and seemed worn out. Disappointing in the extreme.

KLM seems to squeeze as many passengers as possible in their planes by adding more seats. The legroom is insufficient. The armrest does not fold up completely which makes it difficult, if not impossible to get out of your seat especially if the row in front of you has their seat in reclining position.

The seats are hard and do not recline well. I had more space and felt more comfortable on their 737-800. If possible try and get Row 10 on the right and left hand side of the plane but avoid the middle row. Also note that KLM now charges 50 euros per trip for the seats with extra leg room unless your are an FB Eilte member.

Very uncomfortable for many reasons and not least the pitch - far too small. I felt I was squashed in and the seat in front far too close. The seat width was also not sufficient for a decent sleep. The flight was 10.5 hours long so this was not good at all. I am medium-athletic build and 1.85cms tall - so fairly average.
