Kapok fibre is light, very buoyant, resilient, resistant to water, but it is very flammable. The process of harvesting and separating the fibre is labour-intensive and manual. It is difficult to spin, but is used as an alternative to down as filling in mattresses, pillows, upholstery, zafus, and stuffed toys such as teddy bears, and for insulation. It was previously much used in life jackets and similar devices until synthetic materials largely replaced the fibre. The seeds produce an oil, used locally in soap and that can be used as fertilizer.
