Properly fitting the back and seat cushions is an essential part of configuring the Cub wheelchair for each individual user. Cub cushions are designed with pre-scored cutting guides, allowing qualified providers to customize their size for seating depth, width, and compatibility with lateral supports or hip guides.
This quick tutorial demonstrates how to safely trim both cushions while maintaining comfort, support, and proper positioning.
Why Adjust the Cushions?
Every child has unique postural and seating needs. Trimming the cushions allows the seating system to:
Accommodate lateral trunk supports and hip guides.
Optimize seating depth and width.
Maintain proper pressure distribution.
Create a cleaner fit around positioning hardware.
Improve comfort while preserving postural support.
Important: Cushion modifications should only be performed by a qualified seating professional according to the clinical prescription.
Back Cushion Adjustment
The Cub back cushion includes pre-scored grid lines that make customization simple and precise.
In this video you'll learn how to:
Identify the pre-marked cutting guides.
Trim the foam using a sharp utility knife.
Remove only the required foam sections.
Reinstall the cushion onto the backrest.
Ensure the cushion is firmly secured after modification.
Maintain the recommended minimum back cushion height of 190 mm.
Seat Cushion Adjustment
The seat cushion can also be customized to fit specialized seating configurations.
This is especially useful when lateral supports or hip guides require additional clearance while maintaining proper seating support.
The tutorial covers how to:
Measure the required cushion dimensions.
Identify the factory cutting grooves.
Trim the foam along the pre-marked lines.
Modify the rear or side sections as needed.
Reinstall the cushion and verify that it sits flush against the seat base and positioning hardware.
Tips for Best Results
Measure before cutting
Always confirm the required dimensions before removing any foam. Measure twice to ensure the cushion matches the prescribed seating configuration.
Follow the factory guides
Use only the pre-scored cutting lines. These guides are designed to make modifications easier while preserving the cushion's shape and support.
Use a sharp utility knife
A clean, straight cut helps maintain the integrity of the foam and produces a more professional finish.
Test the fit after every modification
Place the cushion back onto the wheelchair to verify that it fits correctly around lateral supports, hip guides, or other positioning components before making additional cuts.
Adjust only as prescribe
Cushion modifications should always follow the seating plan established by the prescribing clinician or seating specialist to ensure proper positioning, pressure management, and long-term comfort.
