ALOVA Galbé anti-decubitus cushions in viscoelastic with shape memory, designed for people weighing up to 120 kg, are molded with integrated coccygeal relief. The viscoelastic material favours the immersion of the body parts in contact with the support to reduce the maximum pressure values, thus reducing and preventing ulcers. Reinforces the prevention of ischial pressure ulcers. Formed by more than 6 cm thick, and has a declination of the cushion to avoid "forward sliding", total protection with bottom surface adhered to the seat. The fabric is waterproof and breathable, and improves thermoregulation during prolonged sitting.
