With the dropper post you have to make sure it is at its max height before sitting down, as if it hasn't quite got up to the top rachet it will drop down to the next one.
Also make sure the cable isn't too tight, you can slacken it off at the adjustment nut by the lever.
Mine was too tight with caused the post to drop on occasion, since adjustment it's been fine.
