Botanicore Latex: Why We Manufacture our own Latex Foam

Botanicore Botanical Latex mattress Core Comparison

Here at Bedrooms & More in Seattle, we’ve specialized in latex mattresses and bedding for almost thirty years.

We use only botanical latex straight from the rubber tree. Every latex mattress we sell is made with our signature core, called Botanicore™. We choose to sell no other types of latex in the store, either in our 45th Street Bedding mattresses, our pillows, or other bedding items.

Botanicore™ is the purest natural latex available

It’s comfortable, consistent, environmentally responsible, all botanical (straight from the tree, not synthetic or blended with chemical compounds), long lasting, and problem free. Compared to other latex, including “certified organic latex”, Botanicore™ is visibly and structurally better. We have an in-store display of our Botanicore™ latex alongside natural latex samples made with other processes, and customers can observe the differences. That’s why we use Botanicore™ as the core of our 45th Street Bedding mattresses.

Aging latex between 30 and 50 days after tapping from the tree makes for the best finished product. Sap can’t be too ‘young’ or too ‘old’ to when making a superior product. Stirring for a minimum of 8 hours each day ages latex properly without premature hardening.

The next step after aging is whipping soap and air into the latex. Once prepared, latex goes into a mold that resembles a waffle iron. Workers hand trowel the whipped latex evenly across the surface. Rotation and vertical baking until the core is solid makes for the greatest uniformity.

Production occurs near the plantations where the sap is harvested. This prevents the need for additional chemicals. Adding chemicals to stabilize the latex during transport to distant facilities is a common practice for many other companies..

We partner with a second generation company to make our Botanicore™. Together, we are well-versed in the proper manufacturing of mattress cores and have developed a relationship with our manufacturing plant.


Botanicore™ latex is manufactured using a controlled heating process in a vertical oven. This ensures that the final product is consistent, with no surface bubbling and other visual or structural inconsistencies. This process makes the latex core feel equal on each side with uniform density throughout.



Botanicore™ contains no fillers or patches. There are no air pockets that can cause soft spots and it has proven and measurable conformity across the bed. Testing for consistency is integral to the process. We log every core. Mattresses are tracked from the production process on the components through to the consumers home. We ensure conformity to our stringent specifications. Both sides of the natural latex core have the same feel, making it ideal for two-sided mattresses, which is all we sell, by the way.



You know that feeling when you sit down on the side of your bed and worry you might slide off? We’ve designed Botanicore™ so that it doesn’t happen. Every mattress core has PURE Edge Support™ designed and built in. The core does not require glued or added-on edge support.


When saying ‘100% natural latex’ or ‘all botanical latex’, we mean no synthetic or blended latex. Botanicore™ is always exclusively tree rubber. Every mattress utilizes a one-piece mold for that specific size. This allows for consistent density throughout, and for the built-in “pure edge support” that is an integral part of our design. In order to build the larger sizes, many brands will glue smaller pieces together resulting in uneven support side to side, as well as glue ridges.



100% botanical latex is the longest lasting support system for mattresses. Synthetic latex (soy, poly, memory foam, gel foam), which are rubberized plastics, or blended latex (what is often called ‘natural’ latex) foams, all break down; Botanicore™ won’t.


Put Botanicore™ latex next to another latex core and the difference is obvious. Notice the consistency and the finished edge, and then see how the material stretches while other latex foams tear. All botanical latex is the purest, safest, and healthiest latex you will find. Botanicore™ is simply the highest quality natural latex available for use in our two-sided mattresses.
