Possibly the bed's a place of healing (8)
I believe the answer is:
bethesda
'place of healing' is the definition.
(the biblical pool of Bethesda)
'possibly the bed's a' is the wordplay.
'possibly' indicates anagramming the letters.
'the'+'beds'='thebeds'
'thebeds' with letters rearranged gives 'bethesd'.
'bethesd'+'a'='BETHESDA'
(Other definitions for bethesda that I've seen before include "Healing pool (Jerusalem)" , "church" , "Chapel" .)
