Matrx PB Deep Heavy-Duty Back

The Invacare Matrx PB Deep Heavy-Duty Back provides deep lateral trunk support, heavy-duty strength, and everyday seating comfort for larger wheelchair users who need greater postural control. Built with a 7″ deep contour, this backrest offers increased contact around the trunk to help improve seated stability, reduce leaning, and support a more secure upright posture throughout the day.

Designed as the heavy-duty version of the Matrx PB Deep Back, this model combines larger sizing and higher weight capacity with the same durable, comfort-focused construction of the PB backrest family. A lightweight ABS shell provides rigid structural support, while molded foam wraps around the shell edges to create a more protective and comfortable contact surface. Easy Set hardware allows depth, angle, and rotation adjustment, helping providers fine-tune the backrest for fit, alignment, and daily function on manual or power wheelchairs.

Heavy-Duty Deep Support for Greater Stability

The Matrx PB Deep Heavy-Duty Back is designed for users who need both higher-capacity support and a deeper positioning surface. Its 7″ contour provides increased lateral contact around the trunk, helping improve stability and reduce unwanted side-to-side movement during daily wheelchair use.

This added support can be especially helpful for users who experience trunk weakness, fatigue, leaning, or difficulty maintaining midline posture. The heavy-duty design provides the strength and sizing needed for larger wheelchair users while maintaining a practical, non-bulky profile for everyday mobility.

Molded Foam Comfort & Support

The PB Deep Heavy-Duty Back uses molded foam over a durable ABS shell to combine firm support with daily comfort. The foam wraps around the shell edges to help reduce contact with hard surfaces and create a more comfortable seating interface.

For users who need a softer or more immersive support surface, an optional Visco foam upgrade may be available for added comfort and pressure-sensitive support.

Easy Set Hardware & Adjustability

The Matrx PB Deep Heavy-Duty Back includes Easy Set mounting hardware designed for straightforward installation and adjustment. The hardware allows the backrest to be adjusted for depth, angle, and rotation, helping providers match the backrest to the user’s posture, wheelchair frame, and support needs.

This adjustability helps create a secure, functional seating setup while allowing the backrest position to be fine-tuned during fitting.
