Hi pspa123,
The Lanoodles topper will be somewhat in between the feel of a featherbed and a solid latex topper in a very soft ILD and will add a little extra softness and a softer “feel” to your mattress. It will have more resilience and provide more even pressure relief than a featherbed (which has no “spring” to it) but because the lanoodles are loose and can move and “flow” around the body curves more it will also have some of the “feel” of a featherbed. It would also have less risk of alignment issues than a more solid topper.
It’s difficult to describe subjective experiences with words just because they are so subjective but some of my comments about the lanoodles topper are here and here and here and here and another members comments and pictures are here and they also have a video here which may be helpful.
