Compared to memory foam and innerspring, does it sleep hot. The memory foam I just got (Emma), sleeps too hot for my taste, so I will be returning it. I've heard both opinions on how hot latex is.

Hi Slides,

I just went from Tempurpedic to 100% latex Flobed. I've been on the Flobed for two weeks now and find it sleeps much cooler than TP foam. Just my opinion, but I don't feel latex sleeps hot. I even use my electric blanket most nights.

Sorry the Emma didn't work out for you.

I own a FloBeds 100% natural latex mattress also. No, I do not feel that it sleeps hot.

I think most types of foam can heat up and cause some issues.  When I first got a Flobed (blended latex), I was having heat issues.   I tried a fairly new Sealy Posterpedic (with their Sealy foam on top) and had some heat issues as well.

I have found that the more breathable cool memory foams are similiar to talalay latex.  I have tried both on top of my surgically altered Sealy and not noticed much difference.

The old style firm innersprings are cooler, because they are firm and they may not use any foam at all on top.

Dunlop might be hotter than Talalay.  Randys found the Costco all dunlop latex hotter than the Emma.

What you put on top can affect it.  I think wool is warm but seems to moderate the heat a bit.  I won't know for sure until summer.

The less breathable and denser memory foams (like Sensus) are probably hotter than talalay latex.

Sorry I can't be definitive, but there is no easy answer.  I am not sure what you are putting on top of the Emma, but a wool topper might moderate the temperature and it might make it seem firmer as well.

I have a blended latex mattress, and I do not feel it sleeps hot.

In my own personal experience i find my latex mattress cooler sleeping than the Simmons mattress I had prior.  Out of all varieties of foam latex both dunlop or talalay will breathe better than anything else.  I personally think nothing would sleep much cooler than an all natural fibre fill mattress although there are drawbacks to this as well.  And even the worst offending mattresses (most memory foams)  can be made live able with the proper bedding.  I believe with the right duvet, sheets, and maybe mattress protector you could alleviate thermal imbalance issues on just about any mattress.

have had several foam including emma and not even remotely warm let alone hot

have now latex and it sleeps warm...

i really am only interested in opinions of people who have slept  on the bed, whatever it is, during summer months...then and only then will we really know

i am looking forward to finding out more this summer

I don't know, but I imagine most S brands with their PU foam and synthetic tops probably sleep hotter than most other mattresses.
I do believe that wool helps regulate heat and cold.
I sleep hot in the summer but can't say it's because of my foam. I think it's just hot in the summer and one tends to get hot.

One thing I DO know: make sure you don't use too high of a thread count in your sheets because a high thread count does not breathe well. Get the lowest thread count you can feel comfortable with. (Too low and it feels "scratchy" to me; not soft enough.)

real linen made from flax is by far the coolest sleeping sheets you can buy.  and if you get good ones they will last a life time anyway
