Product Overview

3.1 Product Description

The Invacare Matrix Libra cushion A consists of following components:

The best way to avoid problems related to pressure sores is to understand their causes and your role in a skin management program. Your therapist and physician should be consulted if you have questions regarding individual limitations and needs. All cushions  should be selected carefully. Working with your therapist and physician is the best way to ensure that a cushion choice matches your individual needs. As the needs of the individual become more complex, cushion evaluation becomes more important.
The cushion A uses a combination of a molded foam base B and dual layer clinical fluid sac C to provide the highest level of skin protection for users with very high risk of skin breakdown.

Clinical Fluid Sac
The clinical fluid sac utilizes silicone in a unique dual-layer design placed in the ischial/sacral areas to help prevent bottoming out.
Inner Liner and Outer Cover
The inner liner D is moisture resistant to protect the foam. The standard outer cover E is water resistant and breathable. Regular cleaning and inspection of the covers is recommended, see 7 Maintenance, page 5 .
