Spex Wonderseat Space Wheelchair Seating

Designed with paediatrics in mind, common challenges are solved with a small wheelchair system that is designed to work as one.

Wonderseat Space has been designed for children who require a moderate to high level of postural support in sitting. These are children who will typically be using a tilt-in-space wheelchair, so that the influence of gravity on their posture can be managed.

As part of the clinical rationale for this solution, the postural support supplied is able to match the needs of clients with little-to-no sitting control, with supports easily able to be moved away to help with transfers.

Available in two sizes:

Size 0: 6 months to 5 years old

Size 1: 4 – 10 years old
