Hi Clawdia,
You can see my comments about the Lanoodles and how it feels and performs in post #38 here. There is also a video about it here which may be helpful. I also sleep on a Lanoodles pillow which is my current favorite (although it’s not the one that has a zipper and can be customized).
It’s fairly loosely filled and is more like a featherbed without baffles where the lanoodles can “flow” throughout the topper. It adds some pressure point relief and has a very nice “feel” (at least to me) but wouldn’t be as pressure relieving as a thicker topper … although it certainly add a softer “feel” and some “cush” and would also have less alignment risk because of the way the lanoodles “flow”.
I like how it feels but it’s a different product from a thicker pressure relieving layer or solid topper.
I still think that your mattress with the right topper could be your ideal combination and once the search for the “best” topper is complete (as frustrating as that may be when you are still in the middle of it) you will end up with a great combination.
