well.. it's just ...something or someone who can use his body as a couch.

You sir are clearly mad

Couch Man
Couch Man is a action-adventure game about an ordinary couch with extraordinary powers. By day, he quitely sits around in a furniture shop being admired by all, but by night, he's a crime-fighting machine.
Couch Man must defeat the evil villain, La-Z-Boy Reclining Seat, by foiling his plans to get his minions into every house in the world. He'll do this by fighting other forms of seating. The gameplay twist is that Couch Man must also help out tired people who are in need of a seat. The more people he saves the more villain-fighting powers he gets.
Couch Man is being developed by Binary Zoo. It is set to be released in the Spring of 2006.
