First latex mattress purchase, all help welcome!

Hi WVU85,

Welcome to the Mattress Forum! :slight_smile:

You are very kind. Thank you so much for the kind words.

I’m sorry to hear that your Tempurpedic is no longer comfortable for you. Because of the viscous nature of memory foam, and as you are doing a good job of keeping your master bedroom in a sleep-encouraging cooler temperature range, it is normal characteristic of most memory foams to feel hard when you initially get into the mattress.

Memory foam is also generally the least breathable and most insulating of all foams and it is common for people to sleep warmer on such a product. In very general terms, the materials, layers, and components of a sleeping system that are closer to your skin will have a bigger effect on airflow, moisture transport, and temperature regulation than materials, layers, and components that are further away from your skin and softer mattresses or foam toppers will tend to be more “insulating” and for some people can sleep warmer than firmer versions of the same material. There is more about the many variables that can affect the sleeping temperature of a mattress or sleeping system in post #2 here that can help you choose the types of materials and components that are most likely to keep you in a comfortable temperature range.

The Nest Bedding Graphite Latex Mattress is a unique product. It is offered in a Medium/Firm version, and then a soft version. The mattress is all latex. The core is 4" in a “medium firm” range, and then there is a 4" layer that has a poured convolute/“humps” on one side, so it has a different feel on each side and can be flipped to provide a more “firm” feel without the convolute/“humps” being on top, or a “medium” feel with the convolute/“humps” facing upward. A “soft” version is offered with the addition a 3" topper already in its own covering to be placed upon the 8" mattress (which is what you are considering). The layers within the mattress are covered in their own sock to make it easier to handle and flip the upper convolute/“hump” layer.

All of the latex in this mattress is Dunlop and is GOLS certified. The latex is mixed with a natural expandable graphite which has anisotropic properties (helps make the latex more durable). The graphite also assists with thermal conductivity to an extent, and also allows the mattress to meet federal flammability guidelines without the use of any additional FR components (this mattress is classified as a Vegan Latex Mattress). All of the material used in this mattress are high quality and durable materials.

As you’re probably already aware, Next Bedding is a member of this site which means that I think very highly of them and that I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency.

The material certainly is a good quality. The latex layers have a GOLS certification, and the cover is made with GOTS certified cotton.

There is more information about the three different levels of organic certifications in post #2 here and some of the benefits of an organic certification in post #3 here and there is more about the different types of organic, and safety, certifications such as Oeko-tex, Eco-Institut, Greenguard Gold, C2C, and CertiPUR-US in post #2 here and more about some of the differences between organic and safety certifications in post #2 here .

Graphite itself is a very thermal conductive material, and I did link to a bit more information about managing the micro-climate of a mattress earlier in this post.

While latex is a very “clean” material, most of the information about being good for allergies has to do with the breathability of the latex foam, which helps with humidity control, which in turn helps keep the dust mite population at bay (they prefer a more humid environment).

Yes, adding the graphite to the latex does soften it slightly as compared to non-graphite-infused latex. The latex is GOLS certified, which is what I think you meant by “all organic”.

Thickness is more of a by-product of mattress design, and there is no reason that an 8" thick latex mattress using this configuration couldn’t be “in the range” for providing you enough support, although I couldn’t speak for the comfort meeting with your preference.

Using a separate topper in its own covering is a very common way to customize a latex (or any other) mattress, and many people prefer this manner of making a mattress a bit softer, and I personally wouldn’t have a concern with using such a configuration.
