How does our latex compare to imported latex?
LI performs very stringent durability testing to compare its latex
to competitive materials. The following two tests illustrate our
superiority to imported Talalay, Dunlop process, and 100% natural
latex.
Compression Set Test: This test simulates the effect
of body impressions on
the latex after a person lies on the bed for extended
periods of time. Latex mattress samples are clamped to
50% of their original thickness for 22 hours at 158 ° F.
When removed, the percent loss in thickness is measured.
Higher values indicate a higher propensity for the
product to take a body impression over time. LI’s latex
consistently outperforms imported latex.
Percent Loss of Core Thickness :
LI Latex: 3.3%
European Talalay latex: 5.7% (73% more loss than LI)
European Dunlop process latex: 7.5% (127% more loss than LI)
Asian 100% natural latex: 12.5% (279% more loss than LI)
Impact
Test: This test is used to simulate the effect on the
latex when a person continuously gets on and off the bed
over extended periods of time. A block of latex is
tested for Indentation Load Deflection (ILD is a
measurement of foam firmness) and then placed in a
testing machine where a weight is dropped on the latex
repeatedly for 24 hours. The product is then removed
from the machine and allowed to recover for 24 hours.
ILD is again measured and recorded.
Higher loss values indicate a higher propensity for the
material to soften over time due to mechanical breakdown
of the product. LI latex consistently recovers better,
with less loss.
Percent Loss of ILD:
LI Latex: 6%
European Talalay latex: 16% (167% more ILD loss than LI
European Dunlop process latex: 16% (167% more ILD loss than
LI)
Asian 100% natural latex: 15% (150% more ILD loss than LI)
