Input on Some Sherwood Evosleep Models

Hi The Toddler,

Thanks for all those details. You’ve given me a lot to think about. I’ll experiment more with pillows and be more mindful of hunching.

That sounds like a good start.

I’m just tired of the inconsistency with this mattress and the heat issues. I actually had a good night’s sleep last night because the temperature dropped to 66 and the humidity to 38.

Temperature and humidity control are both important parts of maintaining an environment that is conducive to good sleep. There’s more information about the variables that can affect the sleeping temperature of a mattress or sleeping system in post #2 here.

There are 5 inches of memory foam in this thing. Based on what I’ve read here, maybe that’s a little too thick a comfort layer for a side sleeper? I feel that it may not be a coincidence that my area of discomfort is right at the warmest part of my body – that this one area is sinking in a little too far (or even bottoming out?) as a result of the memory foam getting too warm

It is certainly possible that for you this product allows you to sink in too deeply in the uppermost layers, and this would be one of the more common causes of the pain you’re experiencing. Five inches of memory foam can be a bit too much for some individuals.

There are small variations in the surface temperature of the human body (extremities tending to be the coolest, the chest/shoulder/armpit areas tending to be the warmest). I don’t know that it is necessarily that this warmest area is causing you to sink in more, but probably more a combination of the differences in dimensions with the shoulders being wider and sinking in a bit more, this creating more of an insulating effect in this area, which leads to less air circulation and a bit of a warmer temperature, which in turn activates and lowers the viscous nature of the memory foam, which in turn allows you to sink in a bit more until things equalize. While you wouldn’t necessarily be “bottoming out” (all of the layers of a mattress work in unison), you are probably coming close to reaching the densification region of some of the memory foam where it doesn’t flex much as more weight is applied.

And lastly, would there be any harm to the comfort layer if I flipped the mattress over to try the bottom side? It’s 1.5 lb, 28 ILD polyfoam. It seems like that ILD is around what some mattress companies advertise as medium-firm, although it’s usually regarding latex.

There would be no harm in flipping the mattress over, and it may be useful in determining if a bit of a firmer surface layering meets with your needs. This would also be a good experiment to try out.
