Heat and UV will harden the leather, hence why you see old cars with cracked and ripped leather upholstery, and there is little you can do about it other than condition the leather on a regular basis.
If you do want to condition the leather, don't waste your money on expensive leather re-conditioners or creams as one of the best things to use is plain old Mr Sheen in a spray can.
Just spray a very light mist on the leather and rub in.
Don't spray too much, and rub it in well with a soft cloth, and the seats will not only get cleaned, but remain soft and supple too.
If you spray on too much, or don't rub it in well, it can leave a shiny, slippery surface however.
You'll probbly find it is the foam under the upholstery that has also gone hard, and this can be replaced with a softer foam for not a lot of $$$.
I must admit that in the NC's I've dríven, I have always found the seats to be very hard in comparison to Na's and NB's.
