Expensive but look for a Corbin.
Short passenger section, though.

 

That may not work then as my wife will be joining me on my touring but thank you for replying

 

Very easy to add more foam/padding to raise the height of the seat. You could do this yourself if you have basic tool skills. I have the opposite problem. I used an electric carving knife and removed almost two inches of foam and recovered the seat in ultrasuede. I bet there are some tutorials on Youtube that will give you guidance.

 

if you don't want to spend a fortune, have you considered a seat pad?

 

That's a good shout

 

I’ve got a stock seat, the Triumph gel and a Corbin. My wife likes the factory gel, it’s fine for me but gets soft after a few hours (I’m fat) but the Corbin is best for me. My wife, however dislikes the Corbin because as @Steve Ford said they take 2” away from the passenger seat. The stock seat was ok but the foam was breaking down so it got super soft.

If it were me, starting over, I’d get my standard seat redone by a professional upholstery shop with foam that will keep it shape longer. I like the position but it crushes after a while and a few years of use.

 

Some great advice there thankyou. This is my seat. Any ideas if it's stock or some other style/upgrade?

 

“Upgraded” OEM gel. If you put it in the sun they get stupid hot, lol!!! I’m not in the UK but I believe that gel was part of the SE package.
