I can make your seat fit to the rider .lower or higher to fit the taller riders and us shorter guys.
and I use a medical gel it's a half inch thick it's used for wheel chairs and orthopaedic hospital bed to prevent bed sores, also used for a lot of truckers for long driving, the individual squares move separate giving your comfort for a long time siting and I use a qulax foam one inch for that extra soft comfort.
I have been doing upholstery for well over 30 years, I discovered this gel when my grandma was in a wheel chair and complain her butt was sore all the time and seen how expensive these gel seats were so I made her one and she just loved it.
So now I just want to do small stuff because of my bad back, so decided to do motorcycle seats and thought of using this gel.
I did a couple for my own bike and love them, as you can see the Corbin one I did over I put a lower back support this way I don't sloutch and now my lower back does not get sore

I also use a very high quality leather or I can do vinyl for those who Prefers that
These are a few ideas that I could do .
And will stand behind 100% on my workmanship
