Struggling with back pain, DIY layer advice - Side Sleeper 11 Jan 2022 12:20 #31

Dunlop and talalay have very different characteristics so if you are experiencing conformity issues (ie your body parts don't travel into the mattress enough to allow support in other areas) then you should be sticking to talaay layers only. If you and your wife tried a firmer dunlop bed and hated it I can can tell you talalay in a similar firmness will feel completely different. That other mattress wasn't very deep either so my suggestion would be to aim for an 11-12" mattress to give you enough travel to provide the support you need. Now I'm not saying you can always fix deflection issues with simply changing layer materials from dunlop to talalay (mine was a good example of this where even with a deeper mattress I had to resort to an expensive solution such as zoning) but I can say it would be a big mistake to only base your support layer decisions on experience with dunlop alone. If you wanted to try bare bones you could got down to a 19T/32T/36T for your side and see how that feels. You could also do some basic zoning with a 19T or 28T (in the 32ILD layer) depending on what areas were causing issues. Lots of possibilities anyway.

Struggling with back pain, DIY layer advice - Side Sleeper 11 Jan 2022 20:40 #32



Made some other progress with testing:

3" 36 + 3" 28 + 4" 19 = same if not worse mid back hammocking pain. So it doesn't look like softer is the answer.

agreed.

3" 36 + 3" 19 + 3" 28 = the support seemed much better on top, but woke up many times through the night with a different pain like my back was hammocking the other way and had a pressure point at the low spot of my side. I'm wondering if that soft under the medium is allowing too much contouring to the point of causing hot spots. Fit was tight against my side.


I am not clear what you mean when you say your back was "hammocking the other way?"

Separately, hot spots could be from having firmer latex on top. Although it may be more supportive, the tradeoff is less pressure relief.


I did briefly try the 28 folded over with the 36 below and I thought it felt pretty good. Couldn't lay on it long enough to tell though. I'll try to revisit that when I have some more time, but this is at least giving me some direction. I have a feeling that the 3" 19ILD is just too much squish and we need something like 3" 36 + 5" 28 + 1-2" 19".


In your response to Mattrebuild I saw you ordered an additional 2" 28ild. Not sure how that will play out but It might depend on how thick the 19ild layer above it is. At 6'1 185 lbs I personally found 6" 28ild talalay over 36ild dunlop to be supportive enough for my hips but my upper body, being lighter, did not sink in enough, causing alignment problems in the upper back. I also had some hot spots. I also tried this configuration with an addilditional 3" 19ild talalay on top which made everything too soft to offer proper support. Point being, when you receive the new layer you should test varying thicknesses (0-3") of 19ild for the top layer to see what happens.

Another option would be to replace the 19ild with 24ild for the comfort layer on top. The idea is it is still soft enough to offer pressure relief but not so soft you go right through it. This is where I am at right now in my mattress testing.

I would be generally shocked if something like 3" 36 + 3" 32 + 2" 28" + 1" 19 is what we needed, if not exactly what you suggested. I really hesitate to say firmer, but maybe that 11-12" stack of firmer latex would be a totally different game from the Roma mattress we had. (1.5" foam + 3" 30ILD + 3" 40ILD dunlop)


I know you are hesitant to go firmer, but Mattrebuild's suggestion is a decent one. 12" of latex can be very different compared to 9", let alone the 6"+foam you had in the Roma. I would be curious to hear what Mattresbuild thinks of the two configurations below compared to his original suggestion. I may end up having to go this route myself.


2-3" Soft (19ILD) - Comfort Layer
3" Firm (32 ILD) - Support Layer
3" XFirm (32 ILD) - Support Layer
3" SFirm (36 ILD) - Support Layer

2-3" Soft (19ILD) - Comfort Layer
3" Firm (32 ILD) - Support Layer
3" XFirm (36 ILD) - Support Layer
3" SFirm (36 ILD) - Support Layer
