Welcome from Mississippi. Multitude of options for dual seats; Corbin, Rusell Daylong, and triumph comfort tour are the most popular. Never heard of a Sundowner on one, but you could send them the seat pan and let em work on it
Sundowner is a specific model of seat in the H.D. accessories catalog for Harley Davidson motorcycles only. They really are comfortable too.
 
Welcome from another newbie to the forum, but like yourself not new to motorcycles.
 
Hi and welcome from New Zealand.

There are places around that will reupholster your seat, its usually expensive but worth it, I got my front and rear seat re-padded and recovered, they also raised the seat height by an inch or so to suit my lanky frame.
Too far to send it to NZ but you get the idea

Motorcycle seats Tauranga reupholstery seat Bay of Plenty Hamilto

They've done three bikes for me now, there should be a similar place in the UK.
 
Welcome
 
Thanks for all your welcoming replies so far!
Looks like I've missed the brackets, on account of early bed Sunday nights!
Yes, The Sundowner is a HD only seat, but, as Charles Whipkey says, is extremely comfortable, something equivalent would be good. Maybe have to look at the custom route.
