Thanks for your feedback. visco elastic is a type of foam. Similar to memory foam I guessGood question, and discussed on this forum before in length. I have replaced the OEM with Brandrup.... and I am not all that happy. Might go back to OEM again. Brandrup is a bit hard from my hips... a side sleeper. Individual preferences... and I usually like firm mattresses in general, so go figure. I do not know what a "4mm visco elastic foam" you are mentioning will do. ??
that might be possible.... I still have my OEM but I am located very close to NE Switzerland.@ddgp and @Flower Power, perhaps you should swop mattresses!

Same hereI have the Calibed folding mattress. Compared to the VW Comfort mattress pictured by the OP, it's night and day. And I'm a side sleeper too. The full body support is so superior with the Calibed Prestige, which isn't surprising as its 2-3 cm thicker. Sold the comfort and never looked back.
Agreed. We keep ours in the roof, deflated with a camping duvet, having removed the original mattress from there. Gives us lots more space.As said, various threads covering this, an example:

Bottom Bed Mattress
Looking at alternatives to the VW comfort mattress. I’ve narrowed it down to three options (open to others if they are winners), as folllow: Sea to Summit Deluxe self inflating (guess there’s a reason they sell out!) Calibed Prestige III (currently my front runner as most direct swap as it...vwcaliforniaclub.com
For us, it's the Sea to Summit. Bit more of a faff inflating and deflating each day, but hard/soft can be adjusted to suit. We have a little camping pump to inflate quicker![]()
