That being said, in my experience, I have not noticed any increased noise in the F cabin and had a really good sleep in 1A on our overnight SIN-LHR flight. Don't think my spouse who sat in 1F had any complaints either. I think the fold-down bed in 77W F is broader and more comfortable than the bed in Suites, but others may differ. I don't remember a lip/bump in the bed and really enjoyed my flight as I rested well. Hope you will enjoy yours too! Cheers!
