Mars extremo hard floor camper

A 100mm foam mattress would be pretty ordinary as you've found out, Di. I put a 150mm one in our slide-on camper, and even it can compress quite a bit if you sleep in one position for some hours. Upgrade to a thicker one might be the only alternative, unless you could add some padding, like another 50-75mm of foam, available from Clark Rubber?

There's a mob in Clontarf(Qld) that make inner springs for 'vans, campers etc, of any size.

We use this one on our bed - Comfort Overlays - there are more on this page.

G'day Mate.

I had the same problem with my Trayon camper. I put a Froli under matters spring system in under the existing matters and it was the best thing I ever did. Not cheep but was worth every cent.

We spent $160 on a memory foam fitted overlay... Makes a big difference, cooler in summer, and warmer in winter.. Nice n cosy.. Odog

I'm going to try the egg crate mattress first, we simply can't afford to have one custom made for it.

Di, I simply put 4 of those "jigsaw" interlocking mats (cheap, from boating/camping stores) under the mattress, (hip-to-shoulder - the legs don't need it). A vast improvement - and I am 120kilos.
