On the ground, which equals close to 50% of the time on several of the routes I fly regularly, the sUA seats are horrific. The headrest, whose lowered position is usually rigourously enforced by the matrons is situated exactly where the average human's shoulder blades are; as a result you have to hunch forward to avoid them.

Once in the air the situation in that department is improved, but is replaced with the somewhat disgusting spectacle of having the dandruff-ridden hair of the person sitting in front of you brushing against your laptop / iPad / food on its way from your plate to your mouth.

Did UA get a good deal by purchasing seats with seat-backs that are significantly shorter than the industry norm? Is it so people in Y can easily determine the load in F and report shenanigans if the aircraft goes out with empty seats? Why didn't they just make the seat-back taller, and put the headrest there like everyone else does? So many questions
