Re: Latex vs Foam mattresses ?

We just bought a "Purple" mattress. It has two layers of different density foams topped by a layer of some new-fangled polymer, not memory foam, that is waffle-like to promote cooling (and purple in color). We like it. Heavy.

Re: Latex vs Foam mattresses ?

I have slept on Latex mattresses in houses all my life. Good quality latex is nothing like foam as it does not break down much with time: As in over 40 years. It requires air ventilation to be provided beneath it. the preferred method being narrow cedar slats 1.5 X.75 inches with a 1/2" air gap between them, and covered with a wool blanked to stop chaffing. This could be slightly difficult to provide on a boat.?

Through inquires I have made for replacement to fit into the Vee-berth I have been told that quality latex as made in past decades is almost impossible to come by. It is by most standards considered expensive. As for the weight a queen sized mattress is heavier than one person can pick up an carry @ approximately 120 Lbs.

I suppose that is for 10"-12" thicknesses, and fewer or smaller vertical vent holes, or none at all. My 5" latex mattress might weigh in at 40lbs or so, but has more holes than I would like. It is very unwieldy for moving in and out of the boat, but that is seldom necessary. The latex I have seen at the Seattle Boat Show has fewer and smaller holes than the Dunlop I bought in Turkey. Clearly there are differences between suppliers.

I believe it can be had in different durometers (sp ?) But the mattress shop won't have clue. If someone knows how to fined a supplier of 4" real latex foam, it would be worth knowing..

Do not do latex unless you keep others away from your bed, always. Someone with latex allergies could go into shock, even die if they laid down in a latex mattress. Also stay away from peanut butter mattresses. Guy made a beanbag out of peanuts. End result was a kid in ER due to her peanut allergies being triggered from sitting in the bean bag.

/QUOTE], I wonder if you could site me a source for this, please? I do question it, because I think that if styrofoam "peanuts", would not trigger allergic reaction, of course, and if real peanut shells, could certainly, but it just seems unlikely.

Fwiw, I think the whole post was a bit alarmist. I would buy a latex mattress for my boat in a flash. Good quality foam latex lasts a very long time. Latex allergy builds up over time, it seems highly unlikely that some child would lie atop the covers and suffer an allergic reaction, and adults could be warned when you find out they have an allergy. Really, it's the job of the person with the allergy to avoid the substance that triggers the reaction.

Re: Latex vs Foam mattresses ?

We have lived aboard for almost 3 years on a "real " latex mattress . It's been comfortable but I would read the lable on the cover before you buy . Most are covered with thick polyester covers which is way too hot here in Cairns .

There are two types of latex but they are both natural. The difference is in how the latex rubber is processed into foam. The traditional process is called Dunlop. It tends to be slightly firmer on its bottom side due to the process. The other process is called Talalay. It has a more consistent cell structure. Both types come in a various degrees of firmness. Latex actually tends to sleep a little cooler than memory foam. I've been sleeping on one for several years and wouldn't trade it for anything. For a good independent view; www.sleeplikethedead.com

I am intrigued .......... how much more (I realize this will be an estimate, aka a thumb suck) but how much more will it weigh over foam mattress - as a multiple- for a queen size mattress? That is, say three times the weight?

Are there only two choices to make ....... foam or latex?

I have seen many different qualities of "foam" mattresses on yachts

Thanks
To be honest, I don't know. Our mattress is a full queen size, about a foot thick. I've never weighed it, but lifting one end of it to access the storage underneath is incredibly difficult. It almost feels unnatural, like it's fighting back with greater force than gravity.

It was delivered by two big Maori guys, and they were struggling.

Much heavier than the foam mattress it replaced, I dunno, maybe 5 times as heavy( ?) but it's also about twice as thick.

Re: Latex vs Foam mattresses ?

Latex has long been preferable to std foam. Will you like it? hard to say. A latex topper might work for you over your existing foam.

The peanut bag was actually shelled peanuts. One of my first patients when interning at Mass General a billion years ago. Took us quite some time to figure out what was going. Alarmist you say? Well most folks are clueless and lucky when it comes to the health hazards around them.
As far as the latex issue, boats are confined spaces. Latex does chafe and release fine dust to the air. In a big house not much of a problem, especially if the mattress is isolated by pads and sheets. In a confined space where pads are probably not used and sheets themselves may not be used sometimes, then it is a potential hazard to some. Ignorance really is not bliss in this case Ann.

Well of course some people are allergic to Latex, but many are not. ditto for many substances....

Agreed. I have a tree nut allergy. I don't expect others to accommodate my allergy. Of course, if you invite me to dinner I will tell you I have a nut allergy. If you serve nuts in everthing I probably won't accept an invitation again.
As for minor children, they will also be conscious of anything they need to avoid, with the exception of the very young and their parents will be responsible. Its not harsh, its life and we take it very seriously.

Re: Latex vs Foam mattresses ?

To Clarify,....I was quoting the weight for a 6" thick Latex mattress. I have used two of them in over sixty years. (But I am about ready for the next one.)They were both covered in other materials so the allergy issue is no doubt being over-blown here as there is no direct contact. Yes they are very awkward to try to roll up and move. Squeezing one of them through a standard sliding sailing yacht hatch could be very challenging. Providing air circulation to the under side is the most obvious difficulty.
I intend to check out the work of Essentia with a follow up visit. Anyone with prior knowledge of their work please contact me.
