It there anything i can do to save this saddle? Or am I better off tossing it? I was thinking of soaking the seat in something then tigetening it to see if i could pull it back into shape, but I have no experience in this sort of thing so your input is appreciated.

It might be possible, but it would be like closing the barn door after the horses got out! The bottom side shows that the leather has been neglected and dried out. Real leather seats need to be rubbed down with a leather preservative regularly so they don't dry out and crack. Just like what one does with a favorite pair of good boots. That keeps them pliable and able to conform to your body.
If you're a fan of leather seats, Brooks of England still makes them, and they are reported as being very comfortable. But your wallet will probably not like it.

It looks pretty well knackered. Lather it up in your favorite proofide type ointment and lets see if there's any life left in it. It looks misshapen. I've reshaped old brooks by mummy wrapping them in discarded innertubes. It's in need of a tensioning too, but I would do that last.

I like the look of well worn leather saddles better than the new ones. They have an old faded bluejean appeal to them.

SInce it is unridable I would do the following (lots of people will probably advise against this).

1. Soak it in water till thoroughly saturated.
2. Stuff something under it to push the shape back like a plastic bag full of sand or something like that.
-let dry
3. Treat with proofide several times
4. punch holes in sides and lace flaps
5. ride and tension as necessary

Keep in mind that the integrity of leather is probably compromised and even after all that it might just go right back to the old shape and/or tear at the rivits.

It is VERY important to always keep you leather saddle dry. always stuff a plastic bag under the seat. Some people let them get wet but if you want it to last for decades you will keep it dry ALWAYS. Some people wet them to break them in faster but this only shortens their lifespan.

There is a leather product called Cellugel, that is used in conservation.
it is a Consolidator, it penetrates the substrate of rotted leather and stops the deterioration but it does nothing to reverse it.

You could try it, but the leather would be no stronger or safer, it just wouldn't keep flaking off on your backside.

what's wrong with riding it as is?

I'd take it to an upholstry shop and have them steam the sides and tape it up into shape until it dries. Then ride it until it dies! I love the 'real' patina of it.
If you decide to toss it, I'd be happy to find it a new home and I'll pay for postage!
