Hanging bed (7)
I believe the answer is:
hammock
'hanging bed' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for hammock that I've seen before include "Bed (for swingers?)" , "Resting place slung under tree etc" , "A suspended canvas or rope bed" , "String bed" , "Bed tied between trees?B" .)
