Contour Cushion

Protecting Posture in Early Development

The Wonderseat SuperHigh Contour Cushion is paediatric wheelchair cushion designed to protect and maintain posture.

A comfortable cushion with deep contouring and a supportive level of rigidity, it helps maintain long-term stability and pelvic alignment. The cushion can be used independently, without the full Wonderseat system (which includes a specific back support, medial thigh support and lateral trunk supports), making it a versatile option to pair with alternative Spex solutions, such as the Manta back support.

Designed to be easily reconfigured over time, the cushion can be adjusted to match the user’s evolving postural needs – supporting changes in condition, positioning goals, or functional abilities, without needing a full replacement. Its immersive, adjustable ischial well, higher medial thigh support, and integrated pelvic positioning promote optimal lower limb alignment and support healthy hip development.

Clinical

Benefits

Designed for the user who would benefit from:

Adaptable, structured support to protect and maintain posture over time
Early postural intervention to promote optimal pelvic and hip alignment
A standalone cushion solution that can integrate with a range of seating solutions
Increased stability and reduced posterior pelvic tilt or sliding
A comfortable, high contour cushion with supportive rigidity, which focuses on postural stability over pressure redistribution

Adaptable Medial and Lateral Thigh Contours

Promotes stability and comfort by accommodating individual positioning needs, including abduction, which is especially beneficial for many paediatric users.

Posterior Pelvic Support

The included Flexy Contour (also used in the Spex Constructa cushion) helps prevent the development of poor posture in paediatric users by limiting posterior pelvic tilt and encouraging neutral alignment of the pelvis.

Built-In Larger Contours:

Guides the legs into optimal positioning with structured support, providing stability without reliance on external rigid thigh supports.
