The ISKIO VISCO cushion is made of 100% viscoelastic foam with different capacities. This technical cushion allows, thanks to the characteristics of the viscoelastic foams, an optimal distribution of the pressures. The viscoelastic foam insert causes a complete molding of the glutes and makes it possible to ensure a discharge of the bony protuberances with regard to the areas at risk. The posterior cut and the seat shape have the particularity of discharging the ischial zones and the sacro-coccygeal zone. Recommendations for use: Use adapted for people at risk of pressure ulcer formation, most often related to a posture static disorder in the chair (sliding forward of the seat with over-bearing on the sacro area -coccygienne) in EHPAD and at home. The advice of Sonia Baudry, occupational therapist D.E .: "I advise Iskio visco when a sacro-coccygeal discharge is essential in the context of a prevention of eschar, especially in the presence of a retroversion of the pelvis."
