This Mattress Topper is a revolutionary plant-based raw material sustainably harvested from the Hevea brasiliensis tree. It is then treated with a non-toxic multi-patented process to virtually eliminate all of the antigenic problem-causing proteins that can result in an allergic reaction to natural rubber latex without the use of harmful chemicals typically found in non-latex alternatives. This makes this collection the cleanest rubber product on the market. This collection is free of petroleum, volatile organic compounds (VOCs), harsh chemical and filler agents.
