Bill,
Thanks for the how-to on looking for the better quality foam. However, I am unclear as to the determination on the 4#/ sq. ft. I would expect density to be #/cu. ft. If it is per sq. ft. what thickness should the foam be?

Duke,

Per cubic foot...sorry for my sq foot mistake...I was working on a sq foot calculation on sail area at the same time I posted the info...brain cells crisscrossed!

We just purchased foam for the berth and will be using the rest for cabin cushions. Ordered a king size to be able to use in multiple areas. Bought from Walmart.

We just had one made for our Morgan OI 41.5 and it was very expensive. And I do NOT like it very much. the corners are the size of a king size bed. We had 4 inch firm memory foam over 6 inches and had a cover made from sunbrella. Its OK but not what I thought It would be. So my husband took the topper we bought from Walmart and put it on my side and its better than what it was. When he is done fixing the steering in the aft cabin I will have a new one made by another mattress shop that I have talked to. I would like this one to be made like a Tempur-Pedic mattress that will come in pieces because of the small hallway it has to go down and will be put together in the back when its ready. This is a great topic.

I aireus01,
You should consider an air mattress, (see my post above). Everyone talks about this or that foam and you don’t hear much about air beds. Perhaps everyone thinks in terms of Coleman camping beds, but the professional beds are a totally different animal. My wife and I both love ours, which can be individually inflated to exactly the desired pressure, which never changes. A big advantage on a boat is either side of the bed can be quickly deflated to nothing, so you are not lugging great sheets of foam about when you need to get underneath.
The only thing you need is a 120 volt source, but this can be achieved using a small inverter, because you aren’t changing the pressure very often.

Jolly,

The problem with an air mattress is that it is rectangular. My bunk does not have any angle that is 90 degrees. A mattress for this bunk needs to curve along the hull and thin at the foot of the bunk. Otherwise, I think air mattress is a really good idea.

Well yes, that can be a problem, and nobody makes custom air mattresses that I could find. I overcame this in my aft cabin with foam infills which work just fine. See http://www.schooner-britannia.com/aft_cabin.html The mattress is 72” x 24” and it is possible to squeeze it in a bit at one end because the compressor stops automatically at the pressure you choose, but I agree, you wouldn’t want it popping out half way up the cabin side.
