The Biosense Ultimate mattress with its multizone core gives just the right amount of firmness like the Summum mattress. With a generous layer of horse hair, this is our most luxurious mattress and our flagship model.

The Biosense Ultimate mattress has padding made from horse hair, Biowool and natural silk. This unique combination arranged in layers around the 100% organic latex core provides a feeling of lightness and well-being.

Known for its high strength, horsehair is an extremely resilient fiber. It does not sag and has exceptional cooling properties. Of French origin, our horse hair is bound with a light layer of natural latex.

The Ultimate mattress remains faithful to the Biosense philosophy for the selection of surface materials, namely natural silk for the summer side and Biowool for the winter side. The former has natural anti-dustmite properties and the latter has natural additives to provide the same protection.

certification eco-institutBiosense’s 100% natural latex is certified eco-INSTITUTE (certificate number ID 0410 - 12826 - 001). It is one of the strictest German certifications.

The quality and density of the latex used guarantee the longevity and durability of this mattress, which will retain its original qualities for years.

With the Ultimate mattress, Biosense has reached new heights in terms of comfort whilst allowing you to enjoy the best of nature.
