I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">took a load off</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for sat that I've seen before include "Relaxed" , "Took a chair" , "Used a chair" , "Was couch potato" , "Took (an exam)" .)
