Campervan Beds: RIB Bed vs. RocknRoll Bed - Which is better?

[@timthompson7559]

Do you need a mattress on a rib bed?

I was just thinking the same thing

This bed design looks good, but the Rock n roll Ben mattress looks more comfortable

Wonder what the weight rating is when the bottom seat cushion is reversed. Looks like it could be easily damaged if your weight was on the edge.
