Okay, on mine you grab the top back of the sofa and pull it forward. As you're pulling it towards you you'll need to watch that the seat back cushions don't get hung up. Continue until the seat back has completely flipped and is now part of the bed, so to speak. There's legs to unfold as well. At this point you have the base of the bed.
The air mattress has the air pump built in. There's a cord for 110V operation. You will see a round knob on the face of the unit, twist one way it inflates, and the other way deflates. I hope this helped, as I'm not at home to post pics..
