Theptex is proud to be amongst one of the 6 (!) companies in the world that refrains from adding (cheap) synthetic (SBR) latex to their cores.
We feel it is important that our customers truly understand the differences between natural, synthetic and blended latex. And for this, a bit of rubber history is needed.
The first natural latex mattress was created in the early 30’s, a couple of years after a scientist working for the Dunlop (tyre) company figured out how to transform natural latex milk into foam.
Both World Wars spiked the demand for natural rubber as it was used to make tires and other wartime items. Scientists hurried to find an alternative; synthetic, petroleum-based or man-made latex was born!
It didn’t take long for the mattress industry to start mixing synthetic latex with natural latex or – even worst – use only synthetic latex to manufacture latex foam mattresses. The reasons for doing so are simple; synthetic latex foam is easy and quick to produce at a fraction of the cost of natural latex foam.
Consumers today however are becoming much more conscious and educated about the products they use in every day life so 100% natural latex foam is rapidly finding its way back into the bedroom.
Take a look at this video in which International Sales Manager Remi explains how you can tell the difference between natural and synthetic latex.
|Feature||Natural Latex Foam||Synthetic Latex Foam|
|Composition||Extract from Hevea-Brasilienis (rubber) tree||Petrochemicals (SBR-styrene butadiene)|
|Feeling||Springy and supportive||Less springy, dull|
|Durability||20-25 years||Less then natural foam, will tear more easily|
|Smell||Natural latex smell, similar to wood||Toxic off-gassing|
|Look||Natural imperfections||Unnaturally smooth|
|Color||Creamy/ivory, may turn yellowish when exposed to UV sunlight||Whitish or any color, depends on chemical additive|
|Breathability||Sleeps cools because of open-cell matrix of natural latex which allows good air flow||Sleeps more hot because SBR doesn’t have an open-cell structure so air doesn’t flow|
|Volatile Organic Compounds (VOC)||No||Multiple health concerns because of presence of VOC|
|Other features||Anti-dust mite, anti-fungal and antibacterial by nature||Depends on chemicals added|
