Botanicore™ Latex

Botanicore™ is our signature natural latex, made from the sap of rubber trees. It’s crafted using a time-tested method similar to the Dunlop process—a clean, eco-friendly way to produce durable, supportive mattress cores.

Unlike some latex mattresses that feel uneven or wear out quickly, Botanicore™ cores have a consistent feel from edge to edge and hold their shape over time. That means no lumps, no sagging, and fewer body impressions.

If you’re looking for a long-lasting, natural mattress that supports both your body and the planet, Botanicore™ is a smart choice.

All-natural botanical latex for the best sleep possible.

Botanicore™ Latex is the proprietary latex for all 45th Street Bedding mattress cores, toppers and pillow inserts.

1. Sustainable Cycle

Rubber tree plantations near the equator produce latex sap for use in many industries. Our 100% Botanical Latex originates in Vietnam. Trees produce a milky-white latex sap for decades. The trees are then harvested for furniture and new saplings are planted.

2. Harvesting

Prior to collection of the latex, the bark of each tree is scored; to increase sap production. Workers harvest the latex for use in all kinds of products. It takes many trees to produce enough sap for each core of botanical rubber.

3. Measuring, Mixing & Pouring

After the latex is collected, it is strained to filter out impurities. The rubber is then mixed with a soap and whipped. The latex is carefully measured and poured into large, mattress sized molds where it will be vulcanized.

4. Vulcanizing, Washing & Drying

Once the heated mold is sealed shut, the rubber is vulcanized. The mold is then rotated into the heating chamber to provide uniformity. To ensure cleanliness, each core is repeatedly washed to prevent contamination of allergens and remove proteins and residue. It is heated dry.

5. Testing & Tracking

Variations are not tolerated. Every core is tested for density in multiple locations. Each core is then catalogued and labeled for individual tracking.
