Activated bamboo charcoal is processed at high temperature to create a highly porous fibre structure that adsorbs moisture, odour-causing compounds and some airborne impurities — the same technology used in air and water filtration, applied here to bedding fill. In Malaysia's humid conditions, this helps a bolster stay fresher for longer between washes compared with standard polyester fill.The activated carbon also gives the fibre a naturally firmer hand-feel, which is why the Bamboo Charcoal Bolster suits sleepers who prefer more structure and support — particularly side sleepers using it for shoulder or knee support — rather than those wanting the softest possible fill.
