Matrx PB Deep Back

The Invacare Matrx PB Deep Back is a deep-contour wheelchair backrest designed for users who need increased lateral trunk support, improved seated stability, and a more secure positioning surface than a standard contour Matrx PB Back can provide. With its 7″ contour depth, the PB Deep offers greater trunk contact and postural control while maintaining the durable, comfort-focused design of the Matrx PB backrest family.

Built with a lightweight, rigid ABS shell and molded foam that wraps around the shell edges, the Matrx PB Deep Back helps replace standard sling upholstery with a supportive backrest designed for daily wheelchair use. Easy Set hardware allows depth, angle, and rotation adjustment, helping clinicians and providers fine-tune the backrest for posture, alignment, and wheelchair frame compatibility.

Deep Contour Support for Greater Stability

The Matrx PB Deep Back is designed for users who need increased lateral support to help maintain an upright, stable seated position. Its 7″ contour depth provides greater contact around the trunk than the standard PB Back, helping reduce unwanted side-to-side movement and improve postural control throughout the day.

This deeper support can be especially helpful for users who experience trunk weakness, fatigue, leaning, or difficulty maintaining midline posture in standard sling upholstery or lower-contour backrests.

Molded Foam Comfort & Support

The PB Deep Back uses molded foam over a durable ABS shell to balance firm structural support with everyday comfort. The foam wraps around the shell edges, helping reduce hard-edge contact while creating a more protective seating interface.

For users who need added softness, immersion, or pressure-sensitive comfort, an optional Visco foam upgrade may be available.

Easy Set Hardware & Adjustability

The Matrx PB Deep 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.
