Do more latex layers prevent sleeping hot?

This might be a no-brainer, but i'm not very brainy right now...

My pu foam bed is sleeping hot, even with (and without) a 1" layer of latex on top. Will more layers of latex on top prevent the bed from heating me up?

I really can't see putting fleece on top of memory foam. Most MF is temperature sensitive. It has to warm up to do it's job. Otherwise you can end up sleeping on something that feels like a cold slab of clay. It might be okay on 4 or 3 lb MF that is less temperature sensitive, but you will still lose the true feeling of memory foam. On the other hand, if you WANT to lose the feeling, it might work perfectly!

On latex that doesn't need to warm up to perform wool fleece should be fine but it will still interfere with the true latex experience... which might also be a good thing...

Adding more latex is not going to make the mattress feel cooler. It will probably make it feel warmer since you will be sinking into yet another layer of foam. Lose the jersey sheets. Look for cotton sateen (that's sateen, a smooth cotton with a slight sheen, not satin, which is slick, slippery and usually synthetic ) that sleep cool and get a mattress pad with just a minimal amount of batting. This should make the bed feel cooler.

Yes, actually I think losing the Jersey sheets is what made Electracat's bed cooler. Jersey sheets are VERY hot!

Cloud9, I have to ask this: I always thought the Sateen sheets, although very luxurious (and expensive) were a very tight weave, and so hotter than, say, a 300 thread count cotton sheet. No?

I agree that adding more latex will not make the bed cooler, although replacing memory foam with latex may well make it cooler.

I am one of those who is finding that burying my memory foam BELOW the top layer, under my latex topper and under my wool mattress cover, works very well. I do not LIKE the feel of sinking into memory foam. Actually I DO like it, but I find that sleeping on it makes my arms go number than if I don't, and I have a problem with my arms going numb to a nerve problem at my shoulders. Seems like sleeping on a soft layer like memory foam would help it, but it actually makes it worse, maybe because I tend to stay in one position too long?

Jim, I also found that putting MF under some layers is a nice alternative. Definitely gives the bed some softness without that 'sinking' feeling. Although, in the end, i realize that i just don't like a soft bed...i prefer a thin layer of latex on the top to give it some resilience.

Sateen isn't always expensive. Actually my favorites came from the late lamented Mervyns where they always had great sales-- 40, 50 even 60% off on bedding. They were the Vintage Luxe line. Only 425 thread count. Perfect weight for summer, since I was finding all my 600 and 800 thread count sheets way too dense and hot for summer. These sheets are so light and silky they almost seem to float over my body. When Mervyns was going out of business I bought 2 extra sets so I'd have a nice supply.
