You can find positive and negative reviews on any mattress. Sleeping hot is something that some people do....even on mattresses that aren't known for that.
Since 2007, the outer fabric has a flame retardent backing. Since 2007, there are many complaints about sleeping hopt on mattresses with no memory foam....like the Sealy Embody Perspective. The great majority of these complaints are from women in their 50s....oddly enough.
Memory foam sleeps hot, even if you aren't a menopausal female. Everybody sleeps hot on memory foam....and that ain't cool.
Over the years, there have been lots of changes to memory foam and the materials used with it that are hyped as cool...or cooler. The question is, "Cooler than what?" Cooler than the blazes of Hell ain't so cool.
Of all the upholstery materials used, latex is coolest. It isn't temperature sensitive and doesn't reflect your body's heat back to you.
There is no cool memory foam. It just ain't cool, man.
The flame retardent backing to the fabric is there by law and there's no way around it....and that ain't cool. That's messed up.
