I agree that the positioning is pretty awkward. I’m 6’2” (and shrinking, LOL), and I felt like a pretzel. I also thought the bed was hard.. still and all, I managed 8 hours of sleep on the flight. This was SFO-HKG andreturn, so it was on a 77W. But we were on a 359 from SIN-HKG and the s3at seemed similar.
