4 high back Next dining chairs (AL4)

Purchased from Next, Structurally good condition, hardly used. Wooden legs unmarked. Smoke free home. Comfortable . All have fire safety label under seat.
Currently they have matching stretch covers - colour Teal (the covers are new and clean -they have been washed). I got covers so that when I changed colour of room I could match the chairs to decor.
BUT using covers on the chairs over the years has rubbed the faux leather off, (see photo's) so chairs can't be used without the stretch covers.
