So I have been sleeping on a natural talalay latex mattress for a few months now. When I go to bed I am supported properly. But as the night goes on heat starts to build through the layers. I have 4x3" layers and after I get up if I open the bed up I can feel the heat at the bottom layer and it gets worse as you go up.
The issue is that while I go to bed supported enough. By the time I wake up, given the build up of heat the latex seems to have lost some of its integrity. This leaves my back a bit twisted.
I didn’t expect latex to sleep so hot. Any ideas? Thanks
Hi,
My name is Gabe. I own a mattress manufacturing company in MA. So the reason you are so hot is because you are sleeping on latex and latex is like sleeping on plastic. Most mattresses are made of foam, latex or memory foam. Really none of it is good to sleep on and will start to sag quickly.
My company Don’s mattress service makes mattresses the old fashioned way since 1919. An all cotton inner spring mattress that is tufted and will last you 20+ years. We stand by that with a 20 year warranty. We also make real box springs with a spring in it like our mattresses. Our mattresses are custom made for every customer needs. Please feel free to checkout the website www.donsmattress.com and please don’t hesitate to call the number on the website with any questions. I hope this was helpful
No, latex does not soften with normal body temperature. It has a higher specific heat (it takes a higher amount of heat to raise the temperature of the material) than other foams. Body temperature does not change the ILD of the foam.
What you’re experiencing, in general, points more toward that the combination you have to being a bit too plush in your upper comfort layers, or a bit too unsupportive.
What are you placing your mattress upon? Is it allowing for good air circulation under the mattress?

I had the very same problem and eventually abandoned the thought of a 100% latex mattress. I will state up front that I am a hot sleeper but my husband is not.
We had (note past tense) a Flobeds 3 layer split king and because of the weight difference (me at 100 lb and husband at 185 lb) we had soft, medium and firm layers to experiment with. Husband was very happy with the mattress so I was determined to make it work. But no matter what combo we tried on my side of the mattress I went from being well supported at bed time to waking up with miserable lower back pain in the morning. This even happened with firm on top which would be overkill support for a 100 lb body. But by morning the mattress had softened to the point that as a side sleeper I was twisted into a u-shape like a banana with my midsection sinking too much. We tried different support systems: Simmons triton foundation, plywood platform with holes drilled for ventilation, even tried directly on the floor. I accept Phoenix’s theory that latex is not heat sensitive but my experience was the opposite.
I’m sorry that your latex mattress didn’t work out for you.
Foamed latex does not exhibit a viscous nature (such as memory foam) and even under ASTM testing under much higher temperatures than the normal sleeping environment under the covers, there is minimal compression set under constant strain. The sensation often ascribed as “softening” through the night with foamed latex is generally the result of the flexing of materials above the latex (mattress pad, fitted sheet, mattress covering, various fibers quilted to the mattress encasement), and most often the body’s relaxation and the lowering of muscle tone (specifically in the core and in the erector spinae) that allows for the spine to “sink in” more through the night, which can be a cause of back issues for some individuals.
