Invacare Matrx Vi Cushion

The Invacare Matrx Vi Cushion is a three-part foam wheelchair cushion with a molded visco-elastic insert under the sitting bones. Motion Concepts designs it for skin protection and positioning for people at moderate to high risk of skin breakdown. Westin Healthcare delivers and sets it up across Brampton and the Greater Toronto Area.

This is the Matrx Vi / Visco article. It is not the Matrx Libra fluid cushion, and it is not the Matrx PSP polymer overlay.

Who this cushion is for

The Matrx Vi cushion is for a wheelchair user who needs a prefabricated foam seat with extra immersion at the ischial and sacral area. Motion Concepts rates the standard Vi 300 lb (136 kg). A seating therapist should confirm the size. This page does not give clinical positioning advice.

How it is built

Motion Concepts builds Vi from a soft high-resilient foam top, a molded visco ischial relief insert, and a firm high-resilient foam base. The top has a pre-ischial contour and abductor/adductor shaping. The base has a trochanteric shelf, a waterfall front, and a rear radius that follows sling upholstery. The Meshtex outer cover is moisture resistant and breathable. The inner cover wipes clean.

Funding help for a wheelchair cushion or back support in Ontario

This cushion or back support is an ADP positioning device category item. Ontario's Assistive Devices Program (ADP) can fund 75% of the cost of positioning devices such as cushions and back supports when they are prescribed through an assessment by an ADP-registered occupational therapist or physiotherapist with an eligible mobility device, and some income-support programs cover the full cost. Not every product qualifies, so talk to us before you buy. March of Dimes Canada, Veterans Affairs Canada (VAC), and community programs can also help. Westin Healthcare's staff work with these programs every week and will point you to the right route for your situation. Visit our funding page or call (905) 451-7743 to talk it through.
