Which is the best leather treatment for sport seats

[John 535is (Sydney)]

The black leather on the 535 sport recaro seats is starting to get a get worn. I am concerned about which treatment to use because the leather on the sport seats is very tight, not like the standard seats. Any suggestions?

one of the first things i did when i got my cat was to clean the leater with "saddle soap".I always keep the leather clean,just with a damp cloth and dry the leather immediatley.I also always use a windscreen shade and keep the sunroof tilted to keep the interior temperature as low as possible
I trat the leather with the bmw stuff(my wife bought it for a xmas present)I have only used it once cos the leather looks fine!
the leather looks better now than it did in this pre purchase photo
