Ideal For

Wheelchair users who propel with their feet rather than their hands — including those with hemiplegia or limited upper body strength — will find the 15.5 inch seat height allows them to reach the floor comfortably and maintain a more efficient propulsion pattern. Individuals with shorter stature for whom a standard 18 to 19 inch seat height creates an uncomfortable or unsafe seating position will find the Super Hemi Kit a cost-effective adjustment that avoids the need to purchase a new wheelchair. Individuals who perform lateral transfers to lower surfaces will benefit from the reduced height differential between the wheelchair and the transfer surface. Rehabilitation specialists, occupational therapists, and seating clinicians who work with patients on the compatible Sentra Plus, Astaire Plus, Viper, or Viper Plus models will find the kit a straightforward solution for incorporating hemi seat height into a patient’s mobility or positioning plan.

Frequently Asked Questions

What is a hemi seat height and why does it matter?
A hemi seat height refers to a lower-than-standard seat height, typically around 15.5 inches from the floor, compared to the standard 18 to 19 inches on most adult wheelchairs. This lower position is beneficial for users who propel the wheelchair with their feet, users with shorter leg length who cannot comfortably reach the floor from a standard seat height, and those who perform lateral transfers to surfaces that are lower than a standard wheelchair seat.

Which wheelchair models is this kit compatible with?
The Super Hemi Kit is compatible with the Drive Medical Sentra Plus, Astaire Plus, Viper, and Viper Plus wheelchair models. If you are unsure whether your specific wheelchair model is compatible, check the model name on your wheelchair frame or contact us with your wheelchair’s model number before ordering.

Does installing this kit affect the wheelchair’s stability?
Lowering the seat height changes the center of gravity of the wheelchair, which can affect rear stability. The Super Hemi Kit is engineered for the compatible models listed and is designed to maintain safe stability at the 15.5 inch seat height when installed correctly. If you have concerns about stability after installation, consult a physical therapist or seating specialist.

Is professional installation required?
The kit does not require specialized tools for most configurations. However, if you are not comfortable with wheelchair modifications, we recommend having the kit installed by a qualified rehabilitation equipment technician or contacting the manufacturer for installation guidance.
