Gemma™ is the memory foam brand manufactured by Spaldin Sleep Systems - company from Spain known for their natural sleep products. Gemma mattresses are made of plant oil-based foams.

Spaldin is the first and only major line of mattresses in which ALL components (foam, cover, fire barrier) are certified by Oeko-tex 100 to contain no harmful chemicals. All their mattresses are imported and vacuum packed.

Polyurethane Foam is formed by the reaction of polyols with isocyanate in the presence of a blowing agent. Traditional foam mattresses use polyols derived from petroleum, but in Spaldin mattresses, 40-60% of petroleum-based polyols have been replaced by plant oil-based polyols. While other mattresses use Toluene diisocyanate (TDI) as the catalyst, Spaldin uses MDI (Methylene diphenyl diisocyanate), which does not contain Toluene and is the least hazardous of available isocyanates.
