Hi folks, I'm a majority CX flyer but (at least pre-Covid) used to get 7-8 SQ flights in a year in J or F. Back then I'd occasionally sneak over here to ask your advice. Hear hear to frequent flying feeling normal again!

I have an upcoming flight in F (77W) in a few weeks, both 1A and 1K open. Advice on seats, especially noise related? I've flown these seats a bunch of times before, but can't recall if any difference between 1A and 1K, namely noise issues at night? I also don't think I've ever flown these seats regionally overnight, I hate redeyes but my schedule requires it. I wear earplugs but am sensitive to a lot of talking. Maybe I'm overthinking it on SQ, but 1A on CX F (also 77W) can sometimes get noisy due to crew congregating at Door L1 and getting loud with their conversation.The crew rest stairs by door L1 also kinda being a magnet for chitchat on CX. (I generally avoid 1A and 1D on CX). I don't mind asking them to quiet down but I presume the damage will be done if this is a 5+ hour overnight to Japan. Curious if anything like that exists on SQ.

As a side question, I seem to recall in bed mode the SQ F seats kinda have this lip/bump in them around mid-back -does anyone know what I'm talking about and any way to smooth it out?
