Peeling Leather issues

I also paid $1900 for 3 seater adn 2 seater which made 3 years this month and the 3 seater is peeling on the arm, head rest and seat. We it first started peeling I figured it was a defect and would be covered under the warranty. But of cause the upholstery was only covered for 1yr. It is day light robbery.  They should be made accountable.  It obvious that its a common defect.
