Put your body in all the places you were. If you were laying in
  bed, lay in bed. Move your arms around. "If I was an iPad and I
  wanted to disappear, where would I hide?"

  If you were sitting in a chair, sit in that chair. Move your
  arms around.

  My phone often ends up stuck in a crack between my bed and the
  wall.

  I think we unconsciously make very slow free throw baskets with
  stuff because they always end up in awkward cracks and things.

  Favorite hiding place for the remote is under the chair, JUST
  BEHIND the front leg where it's entirely invisible, and when you
  scoop your hand under it quickly to search, your hand doesn't go
  there.

  So yeah. Good luck. It's findable.
