Cashier, say, rearranged furniture (4,6)
I believe the answer is:
easy chairs
'furniture' is the definition.
(I've seen this before)
'cashier say rearranged' is the wordplay.
'rearranged' indicates anagramming the letters.
'cashier'+'say'='cashiersay'
'cashiersay' is an anagram of 'EASY CHAIRS'.
(Other definitions for easy chairs that I've seen before include "welcomed by professors?" , "Items of furniture" .)
