When you're ready to make the bed up, unroll the topper, throw a sheet over it, and you have an extra-thick sleeping mattress. With a little planning, you can even arrange things so that the seams in the bottom (seat) cushions are "hidden" by the topper (I hate trying to sleep on such seams).

Never forget them. Do something to prevent it from happening again.

Lightbulb Re: Upholstery foam..

Foam density is measured in # per CF, IIRC. I might be misremembering that.
When we had new foam put into all of our cushions in 1995, the upholsterer advised going with a "heavier" 2.6 density.

He said the original factory foam was ordinarily 1.8, and would go flat in any normal useage in a few years. I believed him because ours were flat when sitting on them or trying to sleep. Our boat was constructed in 1988.

The higher-density foam that he used then still "sits" without "bottoming" (pun alert) out right now and we both sleep without having hip bones against the hard bunktops underneath.

So spend a bit more and you will sit and sleep much better! For Many years... !

The Foam Factorys best two grades are 2.8 PCF, that's what I've been using.

Re: Upholstery foam..

my cushions are 6 inch thick, my bed is topped with 2 inches memory foam.

when i change things, i need to go to non-latex foam, or a custom mattress, a lot more pricey than regular latex foam...be aware of allergens in latex--can be fatal or very disabling to those allergic to it, which includes 75 percent of world's population, at this point.

happy sails....

Re: Upholstery foam..

I think you are confused... ordinary foam is urethane. Latex is a premium product that is much more expensive. I would have thought that urethane is more likely to promote allergies than latex.

We use latex gloves at work, and I know one person out of 100 who is allergic to them. A long way from 75%.

Re: Upholstery foam..

When I bought mine it was measured by a "durometer" density (resistance to compression) rather than by the pound. And I got mucky, it has stayed "foam" for many years after cheaper stuff crumbled. It IS possible to buy foam too dense to sleep comfortably, so if you can, lay on a slab and try it out.

A lot of foam places will suggest that they make a sandwich for you, high density foam on the bottom for support, medium density or a "topper" on top to conform to the body, and that's probably the best way to go for a mattress. If it is done right, four inches is all you need, no superthick nonsense.

The problem is that all foam looks pretty much alike and you can't tell if you are getting CocaCola or HoJo Cola. Most of it is made like pancake batter, from chemicals fizzing in the foam to make the bubbles and make it rise. The cheap stuff eventually burns the foam and makes it crumble, so the big trick is to find a reputable supplier that has been around for a while--not the cheapest one.

And there are some places like bedinabox.com that sell foam matresses over the web. Some of their foam is made specifically by BASF, and I trust BASF to make good product.

llatex is the cheap stuff. ask any upholsterer, as i went out and did.

believe it or not---most boats have latex foam for cushions and other itms needing foam as it is so damnably cheap. rodlmao--same with rubber gloves---latex is the cheap stuff.

to buy non latx foam for my boat, i had to wait 4 - 6 weeks for a special order and pay 3000 usd more..lol.. so i didnt buy those.
i went to other upholstery places, including outlets, as i am HIGHLY allergic to latex, and found only availability was latex. the non latex was more than 1000 usd more. at the outlet for the material and foams.

any changes with manufacturers of boats made must have been within the last 4 yrs.....as before then all were latex foam.

Re: Upholstery foam..

zeehag, in the US "ordinary" upholstery foam is indeed polyurethane, and for years the fire rescue squads have been warning people that it creates highly toxic smoke when burned. It is a universal problem for them--so they say--because "all" of the upholstery foam is urethane here.

Maybe Mexico supports a home latex industry, or we need to have the forum members check out their mattress tags to see if the fire squads are all stalking shadows.

Re: Upholstery foam..

When I went shopping for a new mattress for our guest cottage natural foam (a.k.a., genuine latex) was ALWAYS more expensive than polyurethane (a.k.a., synthetic latex).
