Seat Depth Growth System
Convaid extended the standard seat depth growth range to at least 5 inches to allow for up to 5 years of growth for convaid's full line of wheelchairs. This includes Convaid Rodeo, Convaid Cruiser, Convaid Cruiser Planar, Convaid Scout, Convaid Lite Rider, Convaid Safari, Convaid Ez Rider, Convaid Ez Rider Planar, Convaid Convertible and Convertible Planar wheelchair models.
These changes let individuals use convaid's wheelchairs for up to 5 years, and they comply with funding requirements for HCPCS codes, making it a whole lot easier for people to get a Convaid wheelchair funded by their insurance.
The additional growth and adjustment range also eliminates custom modification and allows parents or dealers to make the growth adjustment themselves. Adding growth to the chairs can be easily achieved by replacing the original set of seat tubes with a longer set that is included in the initial standard wheelchair purchase. Exception is the Rodeo, which will come with one tube that is suitable for five years of growth.
Benefits include:
- Adds 5 years of growth
- Growth is STANDARD on each model & shipped with two sets of seat tubes
- Chairs comply with funding requirements for HCPS codes
- Each chair includes the correct anatomical growth range based on hip width
