Cover and Outer shell

Covers are made of two complimentary materials: Spacer fabric for primary contact surface and a smooth Dartex style material with 3mm of silver impregnated foam for the surround. The spacer fabric is very breathable, decreasing heat and moisture retention.  While soft, it also helps to keep the client positioned. The surrounding Dartex material is very soft and slippery, reducing the possibility of upper extremity skin irritation.

The rigid outer shell is made of Kydex instead of the typical ABS plastic. Kydex is significantly stronger, making it a superior surface for mounting hardware, head rest interfaces, and accessories.  It also shapes better than ABS, which enables a more accurate profile and a thicker, stronger shell for complex shapes.

Inner Shell and Auxetic Foam

The unique Original Matrix Inner Shell see-through and feel-through design enables easy confirmation by the therapist or evaluator and achieves unparalleled airflow, combating heat and moisture retention. The infinite shape adjustability of the inner shell (during or after delivery) allows for support of the client in all areas.

Laying between the cover and inner shell is an Auxetic foam liner. Auxetic foam has skin protection properties far beyond other, non-auxetic types of foam. Auxetic foam does not deflect like other foams, ensuring that the user does not bottom out. It also has incredible shear protection and is soft to the touch while preserving the form necessary to maintain positioning. An incredible best of both worlds!
