Rooms To Go Leather furniture is falling apart bit by bit. Port Saint Lucie Florida

We bought 2 chairs barely 3 years ago. We are snow birds so just use them half a year. There are no small children or animals in the house. The air is left on when we are gone. The chairs started flacking and peeling after 3 months. When I checked the warranty it stated it was only for stains. Last year the flacking peeling increased. This year, it's now unusal for us to sweep up a half a cup of little particles. These particle look like bits of plastic.
