Re: Questions about using a Memory Foam Mattress on your Boat Please...
Going on our 12th season with a 2 inch thick Walmart memory foam topper over the standard Hunter bedding and it is extremely comfortable. We sleep as good or better on the boat as we do at home. Our bed is Standard queen size, so didn't need any trimming. We use fitted sheets for the lower sheet and the corners fit over the topper and the bottom cushions (4"). I think we have flipped it a few times just to refresh it. No mildew or mold, but when we are on the boat we use HVAC (heat pump) full time when at dock or out sailing/cruising so humidity buildup is not an issue throughout the boat.

If the thing only cycles on every couple of months or so, I would think an inverter would work just fine.

Re: Questions about using a Memory Foam Mattress on your Boat Please...
Proper Memory Foam is closed cell so body moisture does not migrate through.
We lifted our existing mattress and used a dehumidifier to ensure it was really dry before we put the MF topper on. Had no mildew issues in nearly 2 years living aboard.
We live in a moist but temperate climate. Might not be the same in the tropics.

Re: Questions about using a Memory Foam Mattress on your Boat Please...
We have a faily dense standard foam V berth with Wally mart 3 " topper that works well.
I was concerned when I jumped up the first time and it remarked "Who is the new guy"! LOL

Re: Questions about using a Memory Foam Mattress on your Boat Please...
For something you'll be sleeping on regularly, you need the best quality foam you can get. For foam, heavier means better.
I started with 5" thick of the super HD foam from The Foam Factory. This is too hard, but you can make a mattress softer easily - you can't make it harder. I fine-tuned it by adding a 2" layer of soft foam. Now I have excellent support AND a soft top to the mattress. You could use a topper of memory foam too, indeed I think my mattress would be perfect with a 1" memory foam topper on top of what I have.
In both cases I bought king-size mattresses, and cut them to shape with an electric carving knife.
Start with a top-quality base.

Re: Questions about using a Memory Foam Mattress on your Boat Please...
Geez, gotta add foam chemistry to our seamanship skills too, I guess.
A lot of this just seems silly to me. Princess and the Pea stuff. Granted, I am a minimalist but all these layers?? My V berth has 36" of air draft. How much can ya afford to lose to appease rampant consumerism?
I suspect 2 or 3" of firmish, closed-cell foam would be adequate for most and healthier to boot. Here's some mattress porn to enjoy.

Re: Questions about using a Memory Foam Mattress on your Boat Please...
i have had a 2 inch memory foam topper now for over 5 years. as the cushions in this boat were 6 inch thick when i bought it, this made a lovely bed on top.
there is no problem with heat..i place padding on top of this so there is no contact between me and the foam.... most comfy. sometimes i place a thermarest pad under my cushions for extra comfort...

Full disclosure: The pic I just posted is of a young Zeehag at home in San Diego. That's all I can say (and continue to live).

Re: Questions about using a memory foam mattress on your boat please...
Now I know who to talk to if I need advice on foam...thank you!
I haven't decided yet whether to go with the cheap 6" Spa Sensations Full mattress at Walmart for only $141 or spend over double that and make my own. Does anyone know of a cheaper place to buy memory foam and high density polyurethane foam than foamfactory.com?

The best way to measure quality is to weigh the memory foam. It should NOT weigh less than 4 pounds per cubic foot...you'll need to do the geometry.
The Lux foam you mentioned is polyurethane foam and probably 3.2 pounds per cubic foot. Polyurethane foam should NOT be used at weights less than about 2.5 pounds per cubic foot.
A 2" layer of high quality (4 pounds and up) memory foam glued to 4-6 inches of high quality polyurethane foam is the construction process that Tempur-Pedic uses. A simple zippered denim cover is all you need, except that you may want a quilted fiber topper in the summer for more breathe-ability. You can make a Tempur-Pedic-type mattress for about 15% of the retail price...this is NOT rocket science.
I was in furniture manufacturing for years and have intimate knowledge of foams and their uses.
Do not buy cheap foam that does not meet the minimum weights (above) in terms of pounds per cubic foot.

Re: Questions about using a Memory Foam Mattress on your Boat Please...
I considered getting one of those memory foam sofa bed mattresses because they are only 4" thick until I noticed that they are only 6' long. My current mattress is only 6'-3" and I have to sleep semi-diagonal on it so my feet don't hang over the end. Hmmm, I wonder if I could glue a few more inches of foam to the end so it would be longer?

Re: Questions about using a Memory Foam Mattress on your Boat Please...
Thats interesting because both of the Walmart memory foam mattresses that I've had weren't hot at all.

I read somewhere that the first generation MF had a thermal property that later formulations eliminated.
