Endless trouble accommodating 100 beds (6)
I believe the answer is:
futons
'endless trouble accommodating 100 beds' is the definition.
I can't judge whether this definition defines the answer.
'endless trouble accommodating 100 beds' is the wordplay.
'endless' means to remove the last letter.
'trouble' becomes 'fuss' (both can mean commotion).
'accommodating' indicates putting letters inside.
't00 beds' becomes 'ton' (I can't justify this - if you can you should believe this answer much more).
'fuss' with its last letter taken away is 'fus'.
'fus' going around 'ton' is 'FUTONS'.
Can you help me to learn more?
(Other definitions for futons that I've seen before include "Japanese padded quilts" , "Mattresses for the floor in Japan" , "Japanese mattresses on the floor" .)
