When the document was delivered, I once got a fright because she was delivered rolled up and has thus always arched when lying down. I have, however, pressed for some time under a wooden board, and now it is smooth as ice :-). Especially Praktis is also the transparent film, under which one can place Stundenplaene or Aehnlichs. I would recommend the pad definitely. The 3 stars only because of the rolled delivery.
