Spacer for air circulation under the bed?

There's nothing to get into your lungs because it's a durable hard plastic. If you want, PM me your address and I will send you a small piece of it to look at. I bought ten feet of it for my installation, but they sent me a little more than that.

What do people use between the mattress and bottom of the bed to help with air circulation? I was looking at two things:

Nothing. I've never given any thought to needing a spacer.

But, now that the subject comes up, it's worth considering if I were doing winter camping.

Remember when camping in cold weather, your bodies heat is being transferred through the mattress. It will cause moisture under the mattress. With no where for the moisture to escape, mold will form. I've been using Hypervent for 10 years and have no mold or mildew under my mattress. Hypervent keeps the air flowing under the mattress.

Try a piece of the stuff used along the outside of a basemant wall between the tar barrier and the soile . think it is called a dimple barrier .

When we are using the camper nothing goes under the mattress. when its in storage I use the foam tubes that wrap pipes to create an air space. I use 6 spread under the mattress. I also wipe down the air space with Clorox wipes. Bill

Whatever you use make sure you don't raise the mattress enough to obstruct the bottom of your wardrobe doors...speaking from experience when I rebuilt our cabover floor. ;-) The Hypervent looks very much like a furnace prefilter, very inexpensive at HD, you might need a double layer.

Hypervent

That's what I installed under the mattress of my TC

I have had this problem on the boat, when in humid climates. I put in the Froli system, problem solved. Makes the bed a bit more comfortable too. One downside of them is they tend to catch on the sheet when you are making and unmaking the bed. Not a big deal, but a negative nevertheless. I have used DriDek under other things on the boat to allow drying, but I don't think it would work very well under a mattress and bed clothes. They will just sink into the spaces and seal it because they are so thin. Some say that whatever you use should be springy, because it is the motion of the sleepers compressing/uncompressing which pumps air in and out that makes them effective.
