Shoulder pain side sleeping with DIY build while back sleeping is fine. Adding more comfort layers feels like too much but not sure what to adjust? Support: 1”HD foam & 8” coils & 1.5” HD foam; comfort: 2” medium latex & 2” memory foam & 1.5” serenefoam. I’m 5’4” 135lbs.

Tl;dr: I know I'm already up to more than 5" of comfort layers, and adding more seems like a bad idea, but I need to be able to side sleep and I'm not sure what the best path forward is!

Longer version: I did mattress surgery on a now-discontinued Brooklyn bedding model and kept the support layers, so current set up is:

1”HD foam (part of original build) 8” coils (not sure of exact specs but they’re individually encased; a third party site that still has the description refers to them as quantum edge pocket springs). 1.5” HD foam (still glued to coils so I didn’t want to remove it) 2” medium Dunlop latex from SOL 2” 4lb memory foam from BB 1.5” Serenefoam (salvaged from original build but not viable as a long term solution since it’s only on my half of the bed).

Back sleeping is fine with this setup and without the Serenefoam, but I’m still getting shoulder pain when I try to side sleep (which was even worse without the Serenefoam).

My husband is 6’ tall and 210lbs, and he’s happy with his half of the bed which doesn’t have the Serenefoam (he’s also a side and back sleeper). I don’t like the feel of all latex, hence the memory foam — I like to sink in some, but not too much, and don’t want things to feel too bouncy.

I need to make an adjustment, but am really not sure what direction to head in. Add 1” of soft latex somewhere (or add one more of the medium)? Replace the medium layer with soft? Replace the serenefoam with poly foam? I need more comfort without sacrificing support, and it feels like I’m so close but not quite there!
