Hello everyone. I am embarking on a DIY build after researching various mattress brands and feeling a bit frustrated and confused about all of the marketing obfuscation.
I am predominantly a side sleeper, but I tend to run hot. I am 5’10", 165lbs. I am currently on a Sleepy’s Cool Plush 12" Memory Foam Mattress from 2018. The line is discontinued, but according to Wayback Machine it seems to be 3" memory foam and 9" high-density poly-foam, with a “PCM Gel Top Surface Layer.” My main complaint about the mattress is heat retention. My girlfriend thinks it isn’t quite firm enough. I don’t mind the current firmness.
My conundrum is thus: I’ve heard that Memory Foam is bad for heat, and that Latex is bad for side sleeping. How can I get the best of both worlds?
One note, I am not sure how “memory foam like” my current mattress is. Despite being a “plush memory foam mattress” it returns to its original shape relatively fast, and I don’t think I sink in very much:
But this is the only memory foam mattress I’ve ever had, so I don’t know what the norm is.
This is my current DIY plan:
12" Zipper Cover (undecided)
3" Topper (either Talalay Latex or 4lb Memory Foam)
1" Lux HQ-R Polyfoam 1.8lb (foambymail)
8" Quantum Edge Elite Bolsa Coils (arizona premium mattress)
1/2" Lux HQ-R Polyfoam 1.8lb (foambymail)
I won’t lie, I am a fish out of water here. I am accustomed to the memory foam “feel” so I am naturally inclined to just do that again. My hope is that using a coil base instead of a polyfoam base will provide more airflow and help keep the mattress cooler than my current mattress, which may be sufficient to offset the heat problems known for memory foam.
I also read that latex mattresses are a very distinct “feel” and since I’ve never slept on such a mattress (and none of the stores near me have a latex mattress for me to try out). However, a lot of people seem to swear by Latex and part of me wants to make the switch.
So, with that in mind I have a few questions:
-
Will the QE Bolsa Coils increase softness enough to accommodate the transition from Memory Foam to Latex?
-
Is it good to have the polyfoam layers in there? The build that I copied from reddit have them, so I just assumed to as well.
-
Based on the above, is 20 ILD good for me?
-
Do I need to worry much about competing sources of Latex Toppers and determining which one is best?
-
How important is getting the right cover? I was just going to get the SleepOnLatex 12" “topper cover”
