Latex International (LI)
certifies that the compound utilized to make its TalatechTM
natural latex mattress cores and toppers includes natural latex
rubber harvested from the “Hevea Brasiliensis” rubber tree,
currently sourced from tropical plantations in western Africa,
as well as soaps and curing agents.
We do NOT use any man-made or synthetic latex in our
TalatechTM natural latex formula.
The majority of 100% natural
latex sleep products are produced via the Dunlop process, while
our latex is produced via the Talalay process.
LI’s proprietary compound mix required by the complex
Talalay process includes raw materials such as natural rubber
latex, zinc oxide, fatty acid soaps, and sulfur, which are
needed for the vulcanization, foaming, and curing process
Our natural formula makes the
highest quality, most durable, resilient, and consistent latex
in the world. After curing, our latex is washed 5 times to
remove any proteins and residuals. Latex International ILD or
firmness tests all of our natural latex products in 9 locations
to ensure uniform feel throughout the latex core. Durability
tests prove our latex is the most consistent and durable natural
latex product in the world, which means a longer comfort life
for consumers.
Latex International performs
very stringent durability testing to compare its latex to its
competitors.
- Compression Set Test: Samples are clamped to 50% of
their original thickness for 22 hours at 158F, removed and %
loss in thickness is measured. Higher values indicate a
higher propensity for the product to take a set over time.
This test is used to simulate the body impression
effect on the foam after a person lies on the bed for
extended periods of time.

- % Loss of Latex Core Thickness:
LITalatechTM Natural Latex 4.2%
Asian Natural Latex: 12.5% (198% > than LI natural)
