Vegan materials in mattresses

Elizabeth Brownsell asked
26th August 2016

I was interested to read your answers related to vegan appropriate mattresses, but have some further queries about the materials you use.
It is very common that latex is processed using casein (a protein found in animal milk). A few manufacturers of vegan products containing latex do source animal-free latex, as other substances can be used in place of casein. While it is not necessary to use casein, its use is widespread and generally must be assumed to be standard unless otherwise stated. Can you confirm how the latex you use is processed? Is casein or any other animal protein used during the production of the latex?
Could you also please confirm if you use wool or silk in any of the mattresses that you advertise as acceptable for vegans? Do any of the chemicals used in the fire retardants (which I fully understand you are legally obliged to use) contain any animal products, or are animal products used during their production?
Many thanks for the further clarification you can provide.

Hi Elizabeth,

Thanks for your question and it’s a really interesting one. We have an article on natural plant fibres which addresses which of our range our vegan friendly.

Casein is a protein found, usually though not entirely, in animal milk. Sometimes this is used as a paint thickener in an industrial setting. Casein can also be found in milk fibres which became prominent in the 1930’s to compete with wool in the USA.

We do not use casein in our latex. Our fusion latex range is 100% natural latex from the Hevea brasiliensis rubber tree. You can read more about how latex is made here.

Due to the fact our Fusion latex range is 100% latex, casein free they are fully suitable for vegans as they contain no animal products.

For our wool or silk, as these are animal products they are not vegan-friendly. Our Origins reflex, however, is fully vegan-friendly as it is entirely synthetic.  The FR chemicals and treatments used are all man made.

I hope that helps Elizabeth. If you have any further questions please give us a call on 0161 437 4419.

Kind regards Julie
