After Alvin the Treacherous was said to be the king, Hiccup's things that belonged to a king got stolen by him, which also included the throne.
When Hiccup arrived to the Island of Tomorrow, he was revealed to be the real king instead of Alvin. When Hiccup will be crowned, he said that he will sit on a rock instead of the throne.
