The Geo-Matrix™ Hybrid Deep cushion is often used to provide comfort for people who require gentile positioning and contouring with excellent pressure distribution and vibration control. The cascading gel top layer increases comfort and reduces pressure behind the knees. The Hybrid Deep provides added postural support to maximize weight bearing through the greater trochanter and femur to support mild off-loading from the ischial tuberosities.  The hybrid Deep is designed for robust postural support, and is beneficial for those with existing skin issues (stage I or II) or moderate risk for skin breakdown.
