The Back Support that stretches for future growth!
The Growth-Adjust Back Support has in built height adjustment due to it’s unique shell style. Future-proof for user’s growth or a preferred change in Back Support height with the precise sliding adjustment function to accommodate up to 5” / 12.5cm of growth.
The innovative growth adjustment system has an upper sliding interface, meaning that from the initial wheelchair setup the prescriber can be confident that the back support can adjust in height as the user grows.
This is particularly effective for paediatrics. The foam and upholstery unit is matched for the longest growth setting of the Back Support, so there is no requirement to purchase different sizes of padding as the user grows.
The growth-adjustable shell is available with the following padding options:
- Growth-Adjust: For users with symmetrical postures
- Growth-Adjust Spex Classic: Contourable cube padding for users with asymmetries and require pressure reduction
Medifab is pleased to provide the most comprehensive special purpose car seat we’ve every introduced for children and teenagers, providing various kinds of extension accessories and multi-adjustable features to allow longer use by the child and to suit the wide spectrum of children’s needs.
The Carrot 3000 Car Seat is one of the safest child seats in the world, catering for safety and the importance of keeping the child in a safe and supported posture for travel and was was designed, engineered and built to provide optimal positioning & safety for children with insufficient head, trunk, and pelvic stability.
Functional benefits
Padding tucks under Back Support
When the Back Support height is set at a lower height range, the spare padding tucks away behind the cushion.
Padding extends with Back Support
When the Back Support height is extended, the foam padding follows the adjustments that are made.
On-the-spot precise growth adjustment
Shell adjusts in height on the spot without requiring any additional parts. Height adjustment is performed with a continual sliding motion on all 3 adjustment bolts.
Padding options to suit requirements
Choose from standard planar foam, or Spex Classic padding style if contouring is required.
T Shape Option
Removable plate that you can take off if you want the foam to sit between the canes and the ‘T’ to rest on them.
- Rigid T Shape insert fits inside the outer cover and be easily added or removed
- Foam pads can be removed easily
Rigid T Shape insert fits inside the outer cover and be easily added or removed to provide varying levels of support throughout the day. The back support can also be set up without the insert to allow the back support to be positioned in between the wheelchair canes.
Foam pads can be removed easily to allow more movement and re-added to provide more support. Remove the foam pads in the morning when energy and activity is high and add them back in the evening when energy is low and support is required.
