It is chrome and leather vintage 1980's Wave sofa designed by Giovanni Offredi ( thanks to the thread identification ) This does not have Saporiti logo but manufacturer "Bress Designs-England" . Has anyone come across "Bress Designs"? Were they licensed to produce Offredi's designs? Your help is greatly appreciated.

Never knew there was a fake...
Never knew there was a fake Wave Sofa.
The genuine has the little legs holding the cushions that are square and are only attached by threaded rod screws at both ends.
Your Bess looks welded.
Vintage as in 80s which I had was steel with a special coating that gives a dark silver grey steel look.
All cushions are numbered with little tags about 10mm square.
Not sure if they still do special coating but a 90s one i have is brushed solid stainless steel and the sofas are very heavy.
Quality is exceptional in every detail.
Stamped in fabric base under left end cushion towards front but mine hard to see with black stamp on black fabric..
Thank You Starline for the Detail Feedback
By fake I meant that the manufacturer did not have the licence from the designer to fabricate the product. You are correct the studs are round welded to the frame. Very heavy chrome plated frame. ALL in All it looks great. Thanks again for the info and the education.
