Most people associate the Gold Bond Mattress Company with futons and futon mattresses. That is only natural. For one thing, Gold Bond, along with Bedworks, is credited with developing and popularizing the modern Western futon and futon mattress from the original Japanese foldable sleeping mat (Gold Bond, in 1980, actually beat Bedworks (1982) by two years).
Latex from some plants, such as dandelions and members of the Hevea genus, contains isoprenes, which naturally polymerize as the latex congeals, forming a water-resistant material. Using heat to dry the latex increases the polymerization. In 1839, Charles Goodyear discovered that adding sulfur while curing latex made the final product more durable.
Cotton, one of the oldest textile fibers, continues to be one of the most used, even with the wide use of synthetic fibers as well as other natural fibers, and it still is an important material in many mattresses.
