First off Welcome to IRV2
Neither one of my Tiffin coaches had anything that touched the floor when the seat was adjusted. Did you just notice this or has it always done this? I don't believe anything in the Breeze seat is unique to the Breeze. Since you are under warranty, you should give your dealer a call and get the coach in. You can also give Tiffin Service a call tomorrow and see if there is anything you can do in the meantime.
There is also another Tiffin forum - tiffinrvnetwork.com that is all Tiffin owners that you can also contact. Lots of Breeze owners over there that can help.
