Botanicore Latex: Why We Manufacture our own Latex Foam

Botanicore Botanical Latex mattress Core vs. Other Latex

Bedrooms & More in Seattle, has specialized in latex mattresses & bedding for almost 30 years.

Every latex mattress Bedrooms & More sells is made with our signature core, called Botanicore™.  In this blog will cover why we choose to sell no other types of latex in our store and why we only use 100% botanical latex sourced straight from the rubber tree.

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.

Sap from Rubber Tree

Selection of Latex (Rubber) Sap

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 of our latex occurs near the plantations where the rubber 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 by many other companies.

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

The Manufacturing Process: from Rubber Tree to Mattress Core

Our Botanicore™ latex is manufactured in a vertical oven using a controlled heating process. This ensures that the final product is consistent, with no surface bubbling and/or 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 practice stringent specifications to ensure conformity and we log every core. We track each mattresses from the beginning of their production process until they land in a consumer’s home. 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.

Durable Design

You know that feeling when you sit down on the side of your bed and worry you might slide right 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 add-on edge support.

Solid Core Construction

When we say ‘100% natural latex’ or ‘all botanical latex’, we mean no synthetic or blended latex. Our Botanicore™ is 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.

Core Longevity

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.

Visual Quality & Consistency

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