It depends which tt it is for - some beds are only 2m long and some are 2.2 m. The foam is usually 3 inches think but you should be able to fold 4 inches (10cms) in.
Our market has a fabric stall that supplies foam and you can buy it from Abakhan (google it) so you should be able to get some - it's not cheap though.
They do also ocassionally come up for sale on ebay so it might be worth looking there.
can i be rude here and say why would you want to sleep on those horrible hard boards with thin foam that does nothing, whynot just throw an air bed in and be comforatble, just a thought we have been using them for a while now much better
You can be rude, but 3 inches of reflex foam is v comfortable, and being rude back, it doesn't deflate in the middle of the night and you don't freeze on it. Each to their own, if I was going to use anything but foam it would be a SI Mat, can't stand air beds, comfort or reliability.
I refilled my mattresses and cushions last year with high density foam from the foam shop Somerset and am very pleased with the result
Just google the foam shop

Scandalous prices around for the foam, though it's always better than airbeds. Picked up two Conway mattresses off ebay last year, under 20 quid for the two my wife covered them and they are like new. it's definitely worth waiting for as they come up pretty often. Best of luck.
It isn't cheap but it does last if you get either memory or regular high density foam. problem with buying second hand is not the cleaning *steam clean or similar is fine) but the fact that foam does lose is shape eventually so you can't be sure how good they will be
Depending how much room you have I would have thought an investment in a proper sprung mattress would be best witha foam topper if you have room to carry. Plenty on ebay who make to size
There are some good buys on Amazon for memory foam toppers. I have been buying them for boat beds, just cut to shape & cover with some polycotton sheeting.
Quote: why would you want to sleep on those horrible hard boards with thin foam?
Well, seeing as how you asked:
#) So I don't need an air compressor to make my bed
#) So my bed doesn't get punctured during setup/take down
#) So I don't need a 3season bag in summer because I am hemoraging heat through the mattress
#) So I have a comfort setting between 'hard as rock' & 'Butt on floorboards'
#) So I can set up a double bed & sleep in it solo. One person on a double airbed just doesn't work.
Just because a certain setup works for someone, doesn't mean it will work for everyone else. Everyone has a different set of needs & objectives.
------------- My opinion is worth exactly what you paid for it.
Remember if you're going to make new foam mattresses for the TT and not using the original mattress covers you're going to have to think about what you make the underlayer with. If you just use a breathable fabric like cotton then your sweat will condense straight onto the bed board ply and within weeks you'll be growing a lovely crop of mildew. Use a tarp or something similarly waterproof for the bottom of the cover, or just put a tarp over the bed board and slip your mattress into a duvet cover.
Remember too that TT mattresses need aired underneath every day to avoid the dreaded condensation. Simple enough job...prop them up on a few tins of beans or similar when you go out for the day and leave the upper trailer door open to allow air to circulate.
I did try an airbed on the TT bed once btw, when I first developed back problems. A Coleman Double Comfort. My OH, who sleeps on the inside edge of the bed on the side away from the lockers rolled over on his side, the airbed did that dip on the edge that airbeds do and he rolled off into the cabin inner, ripped several fixing points off the inner and ended up wedged in the gap between the bed board and outer canvas. At 3am. Much consternation and fuss followed and we ended up sleeping in the awning on the airbed for the rest of the trip. The inner tent required much repair. We've taken the foam mattresses since.
