I've seen pillar-bedding jobs where the action bears almost entirely on the pillars--with a little pedestal of glass (or Devcon) around them and most of the action suspended between the pillars. I've also seen pillar-bedding where the pillars are completely invisible from the top, with the entire action resting on a glass or Devcon bed. What is the approved way of pillar bedding (if there is consensus on this)?
