Mid cabin mattress 'sweating' underneath

[sprocker]

Hi All,

I have noticed over the past few weeks that the mattress in our mid cabin is sweating underneath where it sits on the GRP, in the morning there is noticeable damp when I lift the mattress.

I know this will most likely be down to the temperatures at this time of year, and I do prop the mattresses up each morning to air and dry off.

Has anyone come up with a fix to stop this type of sweating?

You can buy an underlay

That stuff is just superb.
we had the same condensation issues & propping up the mattress, but not any more, the bunk top is dry in the morning.
I bought "on the roll" & cut to shape with sissors

We fitted the Froli system and found it made a big difference to comfort and no condensation yet. Just a thought. http://www.motorcaravanning.co.uk/shopuk/froli_bed.htm

Thankyou for your replies Gents, I will go with the underlay and see how we get on.

HWMBO has been muttering about wanting such things for ages. My problem is that I need to access the lockers beneath the double berth - it comprises 4 cushions at present so it's achievable, if hard work. But if you fitted either of the systems above, would you still be able to get at the lockers ?

We have a couple of access hatches, but no lockers under the two mattress cushions, so won't be a problem for us. Good thought though.

At risk of putting a small spanner in the works, I would suggest that that Dry Mat (and the alternative of IKEA bed slats) will only work if it is complimented with ventilation - the moisture has to have somewhere to go. The problem with a lot of boat bed designs is that the mattress is usually fully enclosed with a bar along the open end of the bed space to stop the mattress sliding off. This blocks effective air flow and the moisture continues to build up.

We spent a long time cutting IKEA slats to fit the V-berth on our boat, but still find that we need to raise the mattress most days. When I have some spare time, I'm going to install a small bilge blower piped to a grille under the mattress. I reckon that running this for ten minutes every day will be enough to draw the moist air out.

When I re-upholstered the damp mattresses in the fwd casing I used 3mm Spacer fabric (Enay search) for the backing. Its cheap as chips and allows the base of the mattress to breath, which a vinyl cover doesn't. Spacer fabric is the coarse net-like part found on trainers and backpacks.

Thanks for the link to the dry mat supplier - their prices look a bit more sensible than others flogging this stuff.

The plastic mesh-type underlay will completely cure this... have sent you an e-mail.
