Hey Justneedsomehelp,
Thanks for clarifying your geographic proximity, just getting my bearings on what options you may have for shopping and comparisons.
Briefly, let’s break down eco-INSTITUT and SGS certificates for other consumers who may have similar questions. Each are voluntary compliance measures involving various controlled testing conditions which upon successful completion receive the qualifying certification.
Eco-INSTITUT is a German certification for consumer products measuring VOCs, SVOCs, formaldehyde, heavy metals, pesticides, and other chemical substances that can be released when a mattress off-gasses. The certificate is issued following a variety of tests and provides information such as a full declaration of materials used, limit values for harmful substances, laboratory examinations for Voc’s, and much more. You can see an example of one from eco-INSTITUTS’s site here.
SGS/ Société Générale de Surveillance is a Swiss certification and one of the oldest inspection, testing, verification and certification entities in the world, insuring that products meet various standards set by markets and regions globally. Often, manufacturers will seek out specific certificates best-suited towards their marketing stories as a way to build consumer trust, transparency and differentiate their brand where additional product testing is important to the consumer.
The testing and certification by eco-INSTITUT is only for measuring chemical substances; it is not an indicator of how the latex is processed in terms of a percent of “natural” vs. “blended”. Thus, the Alibaba seller’s assurance regarding eco-INSTITUT’s “stringent” standards assures you that their products are safe from exposure to potential off-gassing chemicals, not a guarantee that their latex is “natural”.
If the description states “95% natural”, the other 5% is generally SBR/ Styrene Butadiene, a synthetic binder that when blended with natural latex enhances its natural properties and adds longevity, you can read more about this in Phoenix’s article “Latex- Pros and Cons”.
[quote]From their ads, it states that lines (folds) appearing from surface and sides are perfectly normal, and
edges ( see right side, missing a littble bit) are imperfect since it is a man-made product. They also say that this does not result a drop in performance and there are no exchange of product. It that normal? Since I see all these reviews and youtube videos online and they all have a perfect straight line with no imperfections when they try to sell their product.

You won’t be sleeping on a raw bun (what the rolled latex in these images are called), and the finished product will be covered in a ticking of some kind and perhaps also involving other comfort/ support layers, so the appearance part wouldn’t matter unless the latex is poorly seamed or has degraded in some way before shipping. Without knowing these manufacturers or having a way to test the mattress yourself, there is no way to judge its quality by images alone. What concerns me most is that “there are no exchange of product” statement, leaving you no recourse should you not be happy with your purchase.
The term “talalay” refers to one of two latex manufacturing processes, the second being Dunlop. While it is possible to formulate a completely natural rubber version, the results are of the softest ILD’s and not as durable long-term as a blended version of talalay latex would be, you will read about this in the article I linked above for you. BTW, did you see anything of interest from Lien`A or any of the other manufacturers you are considering?
Thanks,
