Most people do find latex mattresses cooler than visco matts.  Visco (Memory Foam) by its design simply retains heat.  What we call regular poly by it's design does indeed dispurse heat at normal body temps.  I'm not aware of any latex mattress makers that do not place some layers of poly foam (not visco foam) on top of their matts...

There are MANY manufacturers of high quality latex mattresses that do not use polyurethane foam in some or most or all of their models.

-Natura, Flobeds, SavvyRest, SleepTek, Obasan, GreenSleep, Royal Pedic, OrganicPedic, VitalRest, WJ Southard, to name a few...there are many more that I have not listed. 

Today's Flamability testing (Federal 1633 regs) uses, in some cases, with some mattress makers - not all makers - chemicals to block the hight temps that have to be met (1180 degrees for one hour at five different ignition points).  However many makers use other fire blocking tecknology such as kevlar and other similar fabric heat blocking and dispersing methods.

But I doubt if this poor gentelman is sleep with a body temp of 1180 degrees!  So the supper soft poly with a fortrel pad on top of his mattess will serve him quite well!

My first post towards you had nothing to do with flammability....this is about what materials are going to breathe better than others and do a better job of regulating body temperature.  Which natural fibres, cotton and wool, etc will do a much better job of than polyurethane foams as you suggested. 

EDIT: In any event, I have just never heard of someone suggesting to add layers of polyurethane foam to a mattress to help someone sleep cooler. 

I don't understand why you recomend natural fibers when the gentelman said that wool and cotton did not meet his needs.  I'm sure there are other "natural" fibers he could try - but are they easily availabe to him?  Fortrel, even the higher tech qualofill or hollofill will do a fantastic job of disbursing body heat, and he can find them at the upholstrey shop in his area.

By the way - those latex mattress manufacturers you mentioned - do they realy just put flat fabric down on latex with no quilting on the fabric?  I worked for years with Latex International and Sleep Comp Latex and they generaly say a quilted panel on top of their latex make a dramaticly better presentation!

Also, I have a little prior history with Leo, she's a she btw ;)

She had tried a few different options in the wool.  I believe one was an exposed wool pad with the stiffer acrylic backing, and the other was a thin Natura puddle pad.  Personally I can see why both of these have made the mattress stiffer overall.  The challenge is that she had specific needs/wants.  She can feel most stitching done on most mattress protectors and toppers which cuts out a lot of options.  Cotton batting in general is very firm and I can see why that maybe didn't help. 

I still believe a well made product with a decent amount of stretch will not cause these issues.  The comfort plus wool toppers from Natura have more wool in them than any exposed wool pad I have seen, and although they do have some stitching, it is minimal, and they do not have the acrylic backing.  Also a St. Dormeir mattress protector is very stretchy where it is stitched. I have never heard of anyone saying they can feel the stitching on those mattress protectors. 

The other challenge is that I know she would prefer to be as chemical free as possible which means synthetic polyester fibres and poly foams are sort of a last resort kind of thing. 

I also tried a nice soft cotton blanket under the sheet, but found out it was too dense and caused hip pain.  The cooling factor was minimal, not as much as the wool helped.  But the bedroom is 76-78 at night, and for various reasons I can't adjust it down (cost, etc.)

I am forced to use a plush polyester blanket as it causes absolutely no hip pain and my back feels fine too.  Unfortunately the heat factor is bad.  Winter time I will be fine again.

I am now looking at wool blankets at LL Bean that someone there said she used as a mattress pad for 6 months now.  Though she doubled up a king size for her full size bed, as the blanket was thin.  Here is a link and the last review on the first page is the one I am talking about.

Sandman I couldn't find the wool mattress pad you are talking about at LLBean.

I wish I had the nerve to order the Dormeir as the cost is high and no refunds and no returns.  Since I am a special case I will be the one that feels the stitching lines.  Someone here swore I would love the Cuddlebed and would not feel the lines, I DID!  It slept hot anyway.

I know for me this would be too firm.  I use cotton jersey sheets as they stretch so I can sink into the latex layer for side sleeping.  Even regular non-stretching sheets cause pain for me, absolutely no give the them.

No my upholstery shop doesn't carary Fortrel,qualofill or hollifil.  They probably are chemical laden, and probably have no stretch to them.  I was also searching for stretchable terry cloth at fabric stores, and none was found.  Good quality fabrics are hard to come by for the consumer.

As for the cotton and wool the problem is density is too firm and does not stretch, or has a stiff backing, and usually comes with stitching lines on the mattress pads.   So that is why I try blankets.  This is a way that people used to cover their mattresses to protect them, or so I am told.  Mattress pads usually have polyester filled (Cuddlebed) and the pads at JCPenneys sells those.  No local stores even sell mattress pads with cotton filling.  We have a very old one that has cotton filled mattress pad, but the stitching lines bother me still.

I'm not trying to be mean or testy, but try another upholstry shop.  Most "better" decorator pillows are filled with Fortrell.  It is a better version of dacron and decorators perfer the resiliance over dacron.  Dacron, Fortrell, Hollofill, and Qualofill are all monofillament strands of nylon combed into soft fluffy "batts" for use to soften the surface of upholstrey.  Dacron was the first and by far the most common version.  Fortrell is a finer fiber with a much softer feel and more resistance to packing down.  Hollofill is similar to the previous but each fiber ha a single hole running its length (like a straw).  Qualafill is very similar to Hollofill but instead has four or five holes running its legnth (again like a straw).  Both Holofill & Qualofill have an even higher resistance to packing down in large part due to the way they are formed and the holes in them!  This is great stuff.

To my knowlede the only chemicals used during manufacture with and of the above, other than the nylon & heat is water - and a very purifide water it is as they want no impurities affecting the finished product.

The fibers with the holes running the legnth, as you might imagine, are very good at dispurshing heat!  Buy the way, they use these fibers in ski clothing to make sure a skier says warm but not over warm!  If you look at skiers on the slopes at night with an infared scope they glow yellow - from the fibers dumping the extra body heat the skier simply does not need!

Any upholstry shop worth going to knows about these fibers and can always get them if they are not on hand.
