A few weeks ago we picked up our new Tempur. Wife sleeps well in it but I constantly am waking up because I'm sweating. I really enjoy the feel of these beds, but I'm wondering if its the mattress protector that is making things worse. I know this is an issue with these beds, so I'm looking to see what I can do to try and make it cooler.....aside from returning it. |

Memory foam uses (and to some degree holds) the body's heat along with pressure to "activate" it's body conforming properties. It also is much less open celled (breathable) than latex so for many people (including me) it sleeps hot. You will also sink into the foam more when it softens with heat so that too can aggravate heat issues. Some of the newer generation memory foams (Aerus etc) are more breathable and a little less heat sensitive than the regular memory foams but it seems some people still have heat issues with them. A latex topper is much more breathable than memory foam so in theory will alleviate the heat issue, at least to some degree, but it will also change the feel of the mattress since your body heat will not be as close to the memory foam which will then not be able to soften with the heat nearly as much. You may want to see how sandman does with his experiment first as his post today seemed directly connected with yours. When he took off one of his two wool layers he also had heat issues and started sinking into his memory foam more which he didn't like. If you don't mind not sinking in as far, maybe a wool topper over your dormeir would do the trick for you as well regarding heat. Phoenix |

I use a wool topper and a wool filled mattress pad. That seems to feel cooler to me than just using the wool filled mattress alone over memory foam. Adding the topper will probably make it firmer though. Latex also makes some people warm and will affect the feel as well. Should be cooler than some memory foams, because when I put latex above my Sensus MF it does seem a little cooler than when the Sensus is closer to the top of my mattress. So, hard to say which would be better. I think the added wool aborbs the moisture and makes it feel cooler. Not sure how much it actually affects the temperature. Kind of like dry heat does not feel as hot as humid heat. Maybe it helps disperse the heat as well. Not totally sure. I was skeptical at first, but my experience is that I don't seem to be bothered as much by heat when I use more wool as opposed to less. |
