Memory Foam has unique qualities. It is temperature sensitive, which means the foam softens when in contact with the body. It cradles areas that normally receive pressure and supports areas that typically do not. This contouring relieves pressure points, increases circulation and aligns the spine and airways. While remaining firm, air is passed through the foam with every movement, dissipating body heat and keeping the user cool. The Bambillo® Pillow is also anti-microbial, inhibiting the growth of mildew, mould, bacteria and dust mites.
