Matrx E2 Back

The Invacare Matrx E2™ Backrest is a contoured wheelchair backrest designed to provide comfortable trunk support, pelvic stability, and functional freedom of movement. With a 3″ contour depth, the E2 offers moderate lateral support without feeling overly restrictive, making it a practical option for users who need improved positioning while still maintaining upper-body mobility for propulsion, transfers, and daily activities.

The E2 combines an ergonomic back shell, advanced Ripple Foam technology, and highly adjustable mounting hardware to help create a secure, supportive fit. Its moisture-resistant Meshtex™ cover, included lumbar positioning pad, and accessory-ready shell make it a versatile backrest for both manual and power wheelchair users.

Ripple Foam Comfort & Support

The Matrx E2 uses Ripple Foam technology to improve comfort, immersion, and airflow. The rippled top surface helps the foam conform to the backrest contour, while integrated airflow channels assist with temperature and humidity control during extended sitting.

The foam also includes a spinal relief area that provides additional immersion and shear reduction where users may need it most. A supportive high-resilience foam backing helps maintain structure, protection, and long-term durability.

Back Shell & Accessory Compatibility

The E2 back shell is designed for both comfort and clinical adaptability. Its notched sacral cutout helps improve lower pelvic fit, while the contoured shell provides moderate trunk support without unnecessary bulk.

For users who require additional positioning components, backs 14″ and taller include holes for headrest and chest harness interface attachment. Three additional holes are provided for attaching a PostureFlex abdominal support at the desired position.

Mounting Hardware Options

The Matrx E2 Back uses pin-style mounting hardware designed to make setup, adjustment, and wheelchair frame compatibility easier. The hardware allows height, depth, angle, width, and rotation adjustment, helping clinicians and providers position the backrest more precisely for posture, comfort, and wheelchair fit.

• MiniSet Hardware is included on back heights up to 16″. It fits wheelchairs that are 1″ narrower or 1″ wider than the selected backrest width.
• EasySet hardware is included on 18″ and 20″ back heights. It fits wheelchairs that are 1″ narrower or 2″ wider than the selected backrest width.
  • EasySet may also be ordered on backs 12″ and taller when the backrest needs to interface with a chair that is 2″ wider.

Both hardware styles fit 3/4″, 7/8″, and 1″ diameter back canes and can be positioned to avoid frame obstacles such as arm supports or rigidizer bars. Adjustments may be made with the user seated in the backrest, helping simplify setup and fine-tuning.

Cover Design

The Matrx E2 Backrest includes a breathable, moisture-resistant Meshtex™ outer cover designed for daily wheelchair use. The foam and cover overlap the shell to help improve comfort at the edges while protecting the backrest during routine use.

A lumbar positioning pad is included to help provide additional lower-back support and allow minor comfort adjustments during setup.
