Silicone leather: what it is and what it is not

When you hold a Studio Huske mat, it feels like leather. But it is not animal leather. And it is not what you know from cheap faux leather products either. So what is actually in it?

What silicone leather is not

PVC is the material in many budget faux leather products. The problem with PVC is not the polymer itself but what gets mixed into it: plasticisers, often phthalates, are what make it flexible at all. And those plasticisers are exactly why PVC is rightly met with suspicion when it comes to baby products. Phthalates can off-gas from the surface, especially when it is warm.

PU leather, meaning faux leather with a polyurethane coating, is the most common faux leather on the market. It is fine. Plenty of bags, furniture and floor mats are made from it. But PU is not the same as silicone leather. It has a different composition, it ages differently, and it behaves differently around moisture and abrasion.

Animal leather is the original material the word "leather" comes from. Studio Huske mats contain no animal leather.

"Faux leather" is an umbrella term for many different materials: PVC, PU, silicone leather, microfibre composites and more. This is where the confusion starts. If a label says "faux leather", you cannot tell what is meant without asking.

What silicone leather is

Silicone is a polymer built on a backbone of silicon and oxygen. That is a fundamental difference from PVC and PU, which are both organic polymer chains from the petrochemical industry.

The surface of silicone leather is not porous. That means liquid does not get in. It stays on top and can be wiped away. No soaking up, no seeping in, no residue left in the surface. That goes for water, purée, juice, and everything else that lands on a mat in everyday life with children.

EVA foam, by contrast, has an open, slightly porous cell structure. Liquid can work its way into tiny gaps, especially on puzzle mats with interlocking joins. Silicone leather has no joins. The mat is a single piece, and the surface is the same everywhere.

That matters because children lick everything. A non-porous surface gives nothing off, takes nothing in, and can be cleaned completely. No mould in the material, no seams where bits of food get stuck.

Where that matters most is the mat that leaves the house. For the changing mat for on the go, non-porous stops being a line on a spec sheet and becomes the whole point.

Why OEKO-TEX Standard 100/1 is what counts here

OEKO-TEX Standard 100 has four product classes. Class 1 is the strictest. It is explicitly intended for products that come into direct contact with baby skin. Class 2 covers products that touch the skin but are not meant for babies. Classes 3 and 4 apply to materials without direct skin contact. "Has a certificate" is not enough here. What counts is which class the certificate covers.

What gets tested: no heavy metals, no formaldehyde, no phthalates, no harmful dyes. That is a list of harmful substances, not a certification of the material. OEKO-TEX does not say the base material is safe. It says the finished product was tested for these substances and stays within the limits. Tested by independent laboratories, not self-declared.

Studio Huske mats were produced and certified under OEKO-TEX Standard 100/1.

An honest limitation

Silicone leather costs more than EVA foam. That is not a marketing line. It is arithmetic: the material is more expensive, the processing more involved, the route to certification longer. That shows in the price.

The mats are made in Korea, not in Germany or Switzerland. Designed in Switzerland, produced in a certified facility in Korea. If you insist on local production, that is not something I can offer you, and I say so plainly.

If that is the deciding factor for you: fair enough. Here is why I still did it this way. The combination of silicone leather, seamless construction and OEKO-TEX Standard 100/1 was not available in Europe at the time of development. The trade-off between material quality and origin was a deliberate decision, not a way to save money.
