Remi uses it as a safe place to stay out of the wrestling match taking place in the center of the room.
Please ignore the fact that the cushion is sliding off the frame. This happens when a 160lb dog jumps on it unevenly.
Noelle uses it (after chasing Remi off) as a launching pad to jump down onto unsuspecting dogs who are wrestling below her.
Duke uses it as a wrestling mat in an attempt to take down Noelle.
And Ziggy? Well I'm not quite sure what Ziggy is using it for back there...
But whatever it is, he's awfully darn cute doing it!
