Wonderseat Bounce

The Wonderseat family consists of a range of paediatric wheelchair seating systems created specifically to provide children with the ultimate support.

The Wonderseat Bounce has been designed for children who require a moderate-to-low level of postural support when sitting. It’s ideal for users who will be transferring in and out of their wheelchairs with support from parents and caregivers but may require some postural support when sitting for long periods. The seat features fewer moving parts and swing-away options to ensure durability.

The Wonderseat Bounce is available in two sizes; Size 0 (ages 6 months to 5 years) and Size 1 (ages 4 to 10 years).

Benefits of the Wonderseat Bounce:

Spex Wonderseat - easy transfers
Easy transfers

The arm supports are easy to remove using the quick release mechanism to give parents and caregivers easy access during transfers. The anterior trunk support harness features front-access clips that make it easy to get little arms into place without needing to change the length of the harness.

Spex Wonderseat - integrated cam locks
Integrated cam locks

Mounting points for the anterior trunk support harness are integrated into the back support, removing the need for unnecessary hardware and simplifying the adjustment and removal process. 

Spex Wonderseat - hip belt mounting
Hip belt mounting

The hip belt is mounted through numbered slots on a specially designed plate, which can be adjusted to ensure precise placement and easy growth. The slots make it simple to remove the hip belt for washing. 

Spex Wonderseat cushion with shower cap style cover

A shower cap style cover is supplied as standard, making removal for cleaning easier for families and caregivers. The cushion also includes an incontinence cover under the outer cover to keep the cushion dry.

Reduced hardware

Where possible, hardware has been reduced, making the seat lighter in weight but also helping to avoid hardware conflicting or clashing. An example is the stemless head support hardware, which along with the removal of harness guides greatly reduces the hardware at the rear of the back support. 

Spex Wonderseat showing back height adjustment
Easy back height adjustment

The back support height adjustment across the range has been simplified, allowing for easy tailoring of back height using as few fastener points as possible. The cleverly designed dual shell system means only the lateral supports and central bolt need to be loosened for the back support to grow. 

Spex Wonderseat Constructa cushion without cover
Wonderseat Constructa cushion

The innovative Constructa cushion has been specially designed for the Wonderseat range. Modular inner components allow for adjustment and growth as time goes by. The ischial block can be moved towards the back of the cushion as the back support is moved backwards for growth, meaning the ischial tuberosities are always supported exactly where they need to be.
