In this line, the speaker "wheeled a cushioned seat in front of bird, and bust, and door" in order to consider the bird.  The bird conducts himself like a lord or lady and speaks the word "'Nevermore,'" distracting the speaker from his grief over the lost Lenore.  This "beguile[s]" the speaker and prompts him to try to imagine the bird's history.  Further, he recognizes that the bird is "ominous," and he describes him using words with very negative connotations in this stanza -- words like grim and ghastly -- and this arrests his attention, too.  He wants to figure this bird out.  So, his action of pulling up a chair shows that he is both imaginative and pensive.  It also suggests that perhaps he does need a distraction from mourning his dead lover, something he says himself two stanzas later.  He is anxious for anything to take his mind off of his grief, and this bird -- who could be a devil, a prophet, a messenger from the beyond -- is an available subject.
