<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">barracks bed</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for cot that I've seen before include "Function" , "Crib" , "Small bed with high sides" , "Infant's bed" , "Small child's bed" .)
