"But Chara arrived after the migration to New Home, because although Asriel found her in the Ruins, nobody ever made a bed for her there. Instead, they made a bed for her in New Home, which had already been established as the new capital by the time Chara arrived. It was a couple hours walk at the worst"

Yeah but the Dreemurrs still have an additional room in the ruins,thus it was really likely made for Chara before the move where they grew closer to Asriel and thus decided to share the same room with him.
