GI with clean house rearranged item of furniture (6,6)
I believe the answer is:
chaise longue
'item of furniture' is the definition.
(type of sofa)
'gi with clean house rearranged' is the wordplay.
'with' says to put letters next to each other.
'rearranged' is an anagram indicator.
'clean'+'house'='cleanhouse'
'gi' after 'cleanhouse' is 'cleanhousegi'.
'cleanhousegi' anagrammed gives 'CHAISE LONGUE'.
(Other definitions for chaise longue that I've seen before include "Reclining seat with back and armrest" , "Type of sofa" , "Partly backed couch with one arm" , "Sofa for reclining on" .)
