Heavy, sturdy sofa/futon bed

This is a 93" wide sofa with a futon bed. It is heavy and sturdy, with a solid wood frame. To move it out it'll have to go through a doorframe into a hallway, around a corner at the end of the hallway, then out the front door and four steps. Please only take it if you can bring at least one helper and some experience when it comes to moving items like this. Thanks.
