Will PM the listing.
Sofa is by Mario Bellini for B&B Italia ("Camaleonda," 1970). Had to put part of it in storage since all of the pieces would not fit in our current apartment.
I wouldn't venture to say if it is cool or not. I used to be cool, then they changed what cool is and now I mostly spend my days yelling at parking meters.
I tend to respond to spaces on a visceral level, so to my eye this is a very inviting destination and an exceptional use of the sofa is a beautifully tight room. It looks like a great place to have Ann Margaret hump the sofa covered in beans and chocolate.
As to the sofa itself, well, though lately I tend to prefer a little more gloss and glitter, for a lumpy blob it is ethereal. It floats. And I want to sit in it.
