Thank you!

Hi shifty1981,

ILD is just one of the measurements used to indicate the softness of a foam material. The lower the number the softer the material. If you do some testing locally on a mattress where the ILD of the layers are known … it can be very helpful in deciding on your comfort choice for an online purchase. In the absence of any specific testing you have done … then a manufacturer would tend to make suggestions based on “averages” for your height, weight, and seeping positions.

With weight differences as significant as yours. the Eurotop with the split layer makes a lot of sense and it also allows you to change the top layer if you need to for a reasonable cost. Many of the online manufacturers offer a side to side split and they can be a very effective solution for two people who have very different needs.

This would depend on the specific mattress you were comparing it to. A manufacturer is just the company that puts the different layers and components together in a mattress and puts their label on the mattress but knowing the specific layers that are inside a mattress is what makes meaningful comparisons possible.

Many of the Natura mattresses are all latex and use very good quality materials although they are typically more expensive than other manufacturers who use similar materials and have a lower cost. The Ultimate Dreams is what is called a 'latex/polyfoam hybrid" which means that it uses latex in the comfort layers (with 1.5" of quilting polyfoam on top of the latex) and polyfoam in the support layers. Post #2 here has some thoughts abut the differences between an all latex mattress and a latex/polyfoam hybrid. Dreamfoam and some of the other online manufacturers listed in post #21 here have all latex mattresses which also offer side to side splits in either the comfort layers, the support layers, or both.

For most people … using polyfoam or memory foam that has been CertiPur certified (or at the least is made by an American manufacturer) along with using latex which has an equivalent or better certification such as Oeko-Tex doesn’t present a problem with “breathing chemicals” or with “safety” but this is a very complex issue and it can involve a great deal of research to decide “how safe is safe” by your own personal criteria. There is much more information about this if it is a concern in post #2 here and the other posts and information it links to.

I would also consider some local mattress testing if that’s possible because no matter where or how you order it can be a valuable reference point. if you let me know your city or zip I’d be happy to let you know of any of the better options or possibilities I’m aware of that are close to you.
