Material used to ventilate under mattress/cushions?

And they aren't prone to parting with them, so it must be good. They also said they liked the service they received.

Under all the bunks Ive had over the years, I have used 1x1/4 lathe lengthwise on the berth surface, then across that leaving 1 in gaps between the top lathes. I t allows cerculation under the mattress and is pretty inexpensive ! but really you need to increase air cerculation in the boat! air movement is really important to reducing the amount of condensation you are haveing ! Just my 2 cents

Just wanted to answer the OP's questions about the heater adding to the moisture. A major product of combustion is water vapor, so if your heater is burning anything and not properly vented outside, then yes it is adding moisture. Electric heat, or heat with a functioning exhaust should not add moisture.

As a mechanical engineer, the ventilation suggestions sound good, and I'm intrigued by a manufacturer saying night ventilation is better because the water vapor has fallen out of the air as dew and therefore the air you bring in is drier.

Another vote for the Froli system. It is a little expensive but it works. No problems with mildew or any condensation after a year in the Caribbean and several summers in the Chesapeake

Here's the option that I ended up going with. The site where I purchased the material no longer carries it but what I purchased looks like the "Watairvent" and "Groundguard" on this page:

Advanced Building Products - Roof Drainage & Ventilation

It's very stiff and is thicker than the dri-deck panels, etc. so I thought it may vent better. It cuts with scissors so was easy to install. I put it into place with the coarse side down so that the backing supports the mattress more evenly.

(1) Is the mattress open cell foam or closed cell? Your problem could be the mattress itself. (2) Could you drill small holes in the deck under the mattress to increase circulation? If there is stowage under the bed, the entire area could benefit by more air holes.

Another vote for Froli, and use Phifertex on the underside of any cushion cover.

I got an idea from Jonathan... I was in Walmart and saw these fiber air filter things, similar to the watairvent. Cut to fit filters. I bought some and are giving them a try. If they work, the price is sure right... See pic link http://www.flandersfilters.com/wp-co...ges/sm1006.jpg
