Dunno if you remember or not, but when SQ bought their first 747
back in the early 70s, they configured the upper deck with 7 bunk
beds, each within separate, fully-enclosed partitions, for use by
First Class passengers. I believe SQ called them 'Slumberettes.' I
remember sleeping in them on trips to Europe, when my dad was still
with the airline.
Those were removed not long thereafter and replaced with regular
seats, though.
