I need to source some foam for a metal seat pan, been recommended I use closed cell foam to avoid t going mouldy but beyond that I’ve no ideas
I’ve heard of people using yoga mats but that seams a bit too cheapskate and can’t inagine it would be much good. Does anyone know where I can get some proper stuff from?

Google coach trimming suppliers near to you, they should have what you need. You'll need at least medium density foam or if making a custom seat a thin layer of hard density foam with an top layer of medium foam. You could always use medium foam with a gel pad on top (and under the seat cover) if you are getting a seat custom made.
All foam is light sensitive and eventually turns to dust (or goes rock hard if made from Dunlopillo). Trick is to avoid getting direct sunlight onto the foam. Closed cell is normally molded foam to a specific shape and has an outer skin such as OE seat foam. You can get other types of closed cell foam, the coach trimming suppliers can guide you.
If none of the above suit, buy a 400/4 seat and discover what real pain feels like after 100 miles :-\!

Laverda explained this very well, you need the combination of firm and comfortable. You will also need to drill breather holes in the seat pan. P&K get there seat form from Bob, not very comfortable foam ;)

Are the breather holes to let air out when he foam is compressed? How many we talking and what diameter?
I plan on riveting the covering straight to the pan, presumably these will be far too airtight to suffice?

A few at about one inch dia. I would not try to rivet the cover on, it will rip after time. I rivet these to a seat pan and it is easy to firmly hold a cover >>> https://www.upholsteryshop.co.uk/shop/upholstery-sundries/ply-grip/tack-strip-tacktite-30-1-strip/

Does anyone know where you buy red Dunlopillo material.

I have never seen red Dunlopillo Ash, all the Dunlopillo material I have ever used and seen has been either cream or white in colour. Have you tried contacting Dunlopillo, info@dunlopillo.co.uk they may be able to guide you.
I've seen red polyurethane cushion material but it's nothing like Dunlopillo, it certainly wouldn't last as long.
The big advantage of Dunlopillo is its ability to hold its shape as it's normally moulded. We used to use it on Routemaster bus seats but only on the side of the cushion and squab where the leather anti wear panel was stitched to the main moquette. The remainder of the filling was normal foam, Dunlopillo was much to expensive to use for the whole cushion. As Dunlopillo and most other foams were not fire compliant in the 70's & 80's we used to make the Underground seats in layers with springs, chor matting, canvas, horse hair, calico and finally the cut moquette cover. It used to take 5 hours to make an underground seat from scratch, every layer of material was hand stitched using 12 inch double ended bayonet pointed needles. Because we were on piece work and bonus pay we used to go as fast as we could with the result of a few unintentional 'stabbings' with the needles! We used magnetic hammers to pull the tacks out from our mouth, we'd put 30 tacks in our mouth at once and turn them over to face the right way with our tongue ready to pull out from our mouth with the mag hammer!

Just got in touch with a lad I used to know at uni who weirdly ended up setting an upholstery business up. He reckons lire grade high density over reconditioned and is pointing me towards a supplier. I’ll share on here if it works well :)
