Hi, Doug, and List,

We just covered a memory foam matress last summer. The customer
requested an upolstery fabric though. I'm curious why you are going after
Sunbrella? In the years we have been in the business I can't recall any
customer wanting Sunbrella for interior cushions. Sometimes for cockpit
cushions for obvious reasons but is standard marine grade Sunbrella.

We thought we wanted something like a Sunbrella interior fabric, for
protective purposes. However, they're too thick, and don't give enough.
We're going with the closest we can find to the Tempur-Pedic covers, which
are a 75/25 cotton/poly blend (mostly for stretchy purposes) thin terry.

We covered our v-berth cushions with ticking. The same sort of stuff
used on regular matresses and pillows. That has worked for years. We also
have a matress pad for some additional comfort.

TP used to use a Gore-Tex cover, but got complaints that it didn't
transmit
heat well enough. That's another reason we're not going to use the SB
after
all - as lovely as it is, we don't think it would serve that foam well.
We
believe the standard upholstery fabrics would present the same challenges.

Gore-Tex does seem a strange choice for an interior cushion. Not sure
what you mean about challenges with upolstery material. .

However, perhaps you can weigh in on whether there should be some interior
(on the surface of the foam) scrim - and also whether a mesh bottom is
needed.

We generally make the bottoms out of Textilene mesh.

We're thinking in terms of having VentAir under the bedding - we

We have something similar under all our cushions in sleeping quarters.
Works very well.

almost bought a boat (High Time, the one which failed on survey with no
allowance for the results) from the local rep, who's also a broker, and
developed a nice relationship with him. So, we think breathability will
be
well addressed, but without some barrier (like the Gore-Tex, or the
originally planned Sunbrella Interior) fabric, wonder if we'd best do the
belt and suspenders route, particularly since this will be a tropical
application.

Gore-Tex does breathe. That is one of its strengths so it wouldn't make a
very
good vapor barrier.

Thanks for any acquired wisdom you may share :{))
