HyperVent Marine

I think i like the Dri-Dek at this point. Are the tiles made of plastic or rubber? Do you think the optional corners and edgeing is necessary. After you install the tiles can you slide the mattress back into place without the tiles moving.l

- The tiles are made of PVC. So, they're plastic, but flexible enough to be used on a (floor/deck/cabover) surface that's not perfectly flat.

- The corners & edging are decorative. They'd be handy if your cabover area doesn't measure out to a whole-foot increment, but not at all necessary.

- The tiles are lightweight and can slide easily on the cabover surface, however all of the tiles interlock together and once the grid is assembled it's pretty easy to move the mattress around on top of it.

- IMO, don't get too hung up on the Dry-Dek brand. There are quite a few manufacturers of plastic decking tiles and all of these products do the same job of allowing for some air circulation under the mattress. There's no shame in choosing the lowest cost one.
Also, I would not personally choose to use any of the compressible options that have been presented here, due to the fact that they could compress (locally) while the mattress is in use which could reduce airflow.

Sorry I am a little late here, but I took a different approach.
in modern building, when they apply stucco to a wood wall, they now recommend an air gap barrier. It comes in 10' wide rolls. Luckly my neighbor does this for a living and he had some barrier at home. I think I paid him $20 for 10'x10' piece. (his cost)
I think mine is 7/16" thick. I also have the reflective isolation sheet under there, but I can't remember which one is on top. I think the Silver is on bottom.

Thank you all for the replies!

Thanks All

I've never had a condensation issue that I know about. That's pretty interesting. I guess I'll have to go check.

Wow that's more than the Froili....

I just looked up the receipt... I paid $72 for the 30 tiles. At the time it seemed cheap compared to the cost of replacing the mattress, memory foam topper, and sheets :M

There are plenty of low cost plastic tiles available that will do the exact same job:
Block Tiles
Pure Garden Tiles
Dura Grid Tiles
Interlocking Patio Tiles

For my camper the 5' x 6' grid was a perfect fit in the cabover area. YMMV.

(This is my son stomping on the tiles to snap them together)

Also use HyperVent, works well even in the winter.

Used HyperVent in both of my TC’s and wouldn’t own a TC without it.

I don't have any experience with HyperVent....

However, I had a terrible problem with condensation under the mattress... it was bad enough that I threw away the mattress and the bedding. I added a layer of Dri-dek and it's now dry as a bone under there.

Interesting Mark. How much of dry dek did you order for a queen mattress? Back in 2012 I ordered a roll of a product called Dry mesh. Cheaper version of Hyper vent. Forgot to remove it from TC that I sold. Been using a 4 ' x8'Lowes blue insulation board. Seems to work too. Dry deck looks good too.
