Anti-condensation mats under mattresses

[snowleopard]

I am making new mattresses for our main double cabins, normal foam to replace the original latex (hard and incredibly heavy). They are split into two sections at mid-length. My concern is to prevent moisture from condensation and leaks soaking into the foam. I previously had mats of rubberised coir that do the job but stink of rubber, even 14 years down the road.

The biggest problem is that I need to be able to remove it easily to allow access to the engines underneath when lifting the top half of the mattresses. I am also limited on headroom at the foot end because of a step down in the deck so can't afford to use anything too thick e.g. slats.

Any suggestions?

I think I saw this product at the last SIBS - or something very like it.

Worth a call for sample ?

Chris, on Adonnante for the past 10+ years I've used polystyrene foam, probably about 12mm thick. It can easily be cut to shape, reinforced and repaired with duct tape, easily available from a builders merchant, cheap and solves the condensation problem completely.

Cheap closed cell camping mats?

My boat came with plastic dumbbells [ not a great description but the best I can think of ] that slot together and stand about 2 inches high. They allow excellent circulation and have kept my mattress mold free underneath.

I will have the receipt somewhere if you want the name.

On our cat, which has a similar arrangement of engines under the double berths we have Compass wooden slats on springy rubber joiners. Lifted every day to check and both condensation free and more comfortable than without.

Not cheap, but works a treat.

I never knew what it was called but our boat had this material under the mattresses when we acquired her. It seems to work well. It feels like it would slip around, but it doesn't as far as I can tell.

This has come up many times over and it's almost a religious question. You'll find people that swear by Dri-mat and people that swear at it. Others will recommend Ikea bed slats, but they are a lot more work to fit.

For a lot of boats, the problem is that the mattress is completely enclosed and there is nowhere for the moisture to escape which means that nothing is going to solve the problem. We use Dri-mat and raise one end of the mattress every morning to let some air get underneath - that seems to work well.

Ikea wooden bed slats, we have two single sets cut to shape under our double vee berth - fantastic as they are cheap and comfortable. No horrible odour or condensation and extra comfort from the spring effect. Think they are around £17 per set. We spent a bit of time shaping them and also screwed each lathe into its plastic 'cup' which means each set of slats can be rolled up for easier access to under berth lockers. Well worth the effort.

We also used wooden bed slats from ikea very successfully, oddly the product is called 'sultan lade', they would reduce your headroom by about 20 mm, they just roll up for access to under berth items. Main thing is they are cheap and they work whereas we heard mixed reports of the efficacy of specialised expensive mats to place under berth cushions.

Used similar and worked fantastically.

Whatever you get the secret is to make sure it goes up the sides of the mattress too so air can circulate and is not blocked off by sheets/duvets etc.

One good thing about dry mesh/dry may is that you can just bung it in the washing machine every now and again.

Or splash out on getting a made to measure sprung mattress and use with a Scandinavian style thin mattress topper.
Works perfectly.
