New comfort item

[Loren Beach]

Down the road we plan to redo the V-berth cushions, but will likely do two or three inches of firm with two or three inches of medium on top.

Nice!
Decades ago, a journeyman in the biz told me that the most comfortable cushions had the firm layer on the bottom with the medium or light glued to the top with spray adhesive. I could not afford the extra labor when we had the factory covers reused with new foam, so went with 2.6 (fairly high) density foam.
Repeating something else because I believe it's important-- To avoid wrinkles all the foam pieces were wrapped with a thin fluffy layer of "dacron" (his description) before insertion. They still sit and sleep great, decades later. He put all new button tufting in the settee cushions and backs as well.
(IMHO, It's a shame that the "starry night" pattern left the market in the late 90's. EY used oodles of yards of it. )

As a recent and involuntary purchaser of home mattresses, allow me to report that the overwhelming most frequent reason for mattress returns is the complaint that the mattress was too hard. This from the salesman of a mattress at the former price point of a new car.

On a boat, when resting on one's side, if any suggestion of the plywood underneath makes itself known, then i think something is awful wrong, comfort-wise. Of course it is personal, and i am very delicate and sensitive.

But when in doubt, it is probably true to go softer. Which may keep you from drilling holes in your foam, as i did when the Previous Owner chose density over sleep.
