Keith - I can't help but agree with the majority of what RMD has stated. Most plain Clark foam is pretty useless for sleeping on.
Years ago, we used to rebuild our 'dozer and loader seats regularly, and had a hard time trying to get the right density foam, the right amount of compression and shock absorption.
Then we started using an old "gun" upholsterer, who knew every trick in the book, and every product that was available.
He came up with a "crumbed" foam which provided a good base of about 2/3rds of the height of the
seat cushion - overlaid with a moderately firm foam rubber, that made up the top third of the cushion.
That arrangement provided more comfortable seating, than even any of the original manufacturers seating - and we used those materials and that formula for years, with excellent comfort results.
The crumbed foam I have not seen for a long time, and I can't find it online - but it's probably still available somewhere.
I'm sure it was made from recycled foam chunks glued together, because it was made from different-coloured chunks, and it was reasonably firm when you tried to compress it.
I'd be finding an old upholsterer and getting some ideas from him, and see what is available by way of products today.
One things for sure, a good mattress is not made just from one type of foam all the way through, the best mattress is a mix of varying levels of foam firmness, with the softer layer on top.
Cheers, Ron.
