Hi Clawdia,
Just to play devils advocate … a burning sensation in your hips can also be caused by a mattress that is too soft and allows your hips to sink in a little bit to far which can stretch the ligaments and muscles in the hip joint out of their natural alignment. For example if someone’s hip joints are a little bit rigid or lack flexibility and you stand up straight and “push” your hips out to the side some people will feel a similar sensation because the tissues in the hips are being stretched out of their comfort zone. If you bend over to touch your toes with your legs straight then you may feel something similar behind your knees.
In any case your own experience and “best judgement” will always be the final “authority” but I wanted to suggest an alternative possibility that may also account for your symptoms.
The individual pieces are quite soft and springy (not like hard lumps) so I don’t feel them no. It also isn’t like feathers because the lanoodles are much more resilient than either feathers or down but the fill inside the Lanoodles topper is quite low so the lanoodles pieces “flow” and move quite easily inside the cover so the lanoodles aren’t distributed exactly evenly inside the cover and can shift from section to section and be “plumped” in different areas of the topper (something like fluffing up a feather topper).
14 ILD is a firmness rating that is most commonly with Latex International’s blended Talalay latex. The rough equivalent in an all natural Talalay would be their N1 which doesn’t have an exact ILD and would be somewhere in the range of 14 - 19 ILD. You can see LI’s firmness ratings here.
Post #4 here has many sources for different latex toppers and layers in almost any type, thickness, or softness that is available in the market and has sources for covers as well if they don’t come with the topper.
