Hi bmark,
We need to take this step by step. Because I can’t see or feel what you are feeling … because there are so many variables between different people … and because there isn’t a 'formula" that can take height and weight and sleeping position information and turn it into a solution that is specific to any person … the only thing that can help “from a distance” is to match a specific reference point of a specific mattress/topper combination (where all the details of the topper or toppers you are using is known exactly) with a specific set of symptoms and compare each combination in terms of what was better and what was worse compared to other combinations.
The first step is to identify the toppers you have tried (and which ones you still have available). I would need the thickness and the specific type of foam and the ILD (firmness softness level) that was in each one. This will either be memory foam (slow response), polyfoam (fast response), or latex (fast response). These are the three main types of foam.
I’m not sure that Pure latex Bliss even had a 21 ILD or a 28 ILD topper and most of them are much softer (like the one they were suggesting) which I wouldn’t recommend. They come in either 2" or 3" versions with ether 14 ILD blended talalay (which is the one they were suggesting) or 15 ILD Talalay GL. Quite frankly all of these are too soft for most people IMO.
So you would need to confirm that the topper you have is actually 21 ILD (or find out what it is) so it can be used as a reference point. It may be an N2 (100% natural Talalay) which would be in that ILD area or it could be a Celsion topper. If you could phone Pure Latex Bliss and confirm that they even made a topper like this and do what you can to confirm the specifics of what you have it would be helpful. Their phone number is here (on the left under consumer care)
I would also want to know the thickness of the egg crate topper, the type of foam in it, whether you still have it, and any other information you have about it.
Any information about the other toppers or combinations you have tried would also be helpful.
What I would be looking for is a description of the differences between sleeping directly on the mattress (if you have) … sleeping on the mattress with the latex topper you have, and sleeping on the mattress with the latex topper and another topper (like the egg crate) and the order they were layered in each combination (top to bottom). Each will feel different from the other combinations and to use these combinations as a reference point I would need to know the specific differences you felt with each combination and where you noticed the differences between them.
Post #2 here also has some guidelines for choosing a topper which may be useful.
In addition to all of this … some information about mattresses that you have slept on that “worked” for you may also be helpful
There’s a few blanks to fill in but once you have them I can get a better sense of the direction that may have the best odds of working for you.
