Arm rests? (6)
I believe the answer is:
slings
'arm rests?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for slings that I've seen before include "Looped bandages for limb support or missile throwers" , "'''... to suffer the ... and arrows of outrageous fortune'' (Hamlet) (6)'" , "Catapults or arm supports" , "Supporters" , "Arm bandages; drinks" .)
