Use for different users – practical benefits

Users who need caregiver assistance

The SIOUX manual active wheelchair can be used for mobility with self-propulsion. The rigid frame provides a stable base, and seat position adjustment helps set a favourable seating geometry. The fold-down backrest and quick wheel removal make transport easier when travel assistance is required. The wheelchair is intended for indoor and outdoor use, but not as a seat in a vehicle.

Active, independent everyday users

SIOUX supports day-to-day independence at home, work or in education for users with functional upper limbs. 2° camber, pneumatic tyres (7.5 bar) and a compact rigid frame help with turning and obstacle negotiation on typical surfaces. Advanced techniques (e.g., balance / wheelie riding) should be learned under specialist supervision.

Users in rehabilitation and transitioning from standard equipment

SIOUX can support a transition from a standard wheelchair to an active manual wheelchair during rehabilitation. Adjustable seat position, adjustable seat depth and footrest height adjustment in 25 mm steps allow progressive setup changes as needs evolve. Final selection and configuration should be performed in consultation with a physician and/or physiotherapist.

Sizes and fitting

SIOUX is available in five seat widths: 37 / 40 / 43 / 46 / 50 cm. Seat depth is adjustable within ~400–450 mm to support the thighs. Seat height is adjustable within ~450–520 mm, and backrest height is 250 mm. Overall wheelchair width is ~460–590 mm, helping manoeuvrability through doorways and narrow passages.

How to choose sizing (general guidance):

• Seat width: select based on hip width plus typical clothing to support pelvic stability and comfort.
• Seat depth: adjust to support the thighs while avoiding pressure behind the knees.
• Centre of gravity: tuning affects stability and manoeuvrability and should be set by an experienced person.

Important: Final fitting and adjustments (seat position, centre of gravity and footrest height) should be performed by a qualified physiotherapist or rehabilitation equipment technician.

Assembly and safe use

• Before first use: read the user manual; check that all screws, adjustment parts and Quick Release axles are correctly installed and locked.
• Transfers: lock both brakes during transfers; position the wheelchair close to the transfer surface; do not put full body weight on the footrest.
• Footrest adjustment: set height so feet are supported and the footrest does not catch the ground; after adjustment, ensure screws pass through the tube cross-section.
• Obstacles: avoid climbing stairs and high obstacles independently; use ramps; advanced manoeuvres (e.g., wheelies) should be taught by an experienced specialist.
• Outdoor conditions: use on stable ground and avoid ice, sand and mud; after dark, ensure good visibility.
• Vehicle transport: the wheelchair is not intended as a vehicle seat; transfer to the car seat and wear the seat belt; transport the wheelchair folded and secured against movement.

FAQ – common questions about the SIOUX active wheelchair

Can the SIOUX be used with a stair climber?

SIOUX can be transported using a stair climber with ramps (e.g., a climber and dedicated ramp set with securing straps). Compatibility depends on the wheelchair’s wheel track width and how the wheels sit on the ramps, so measurement and verification are required before configuring a set.

What sizes and configurations are available?

SIOUX is available in seat widths 37 / 40 / 43 / 46 / 50 cm. Beyond the standard setup, configuration changes and accessory selections (e.g., side guards, anti-tip wheels, seating/backrest options) allow the wheelchair to be adapted to user needs.

How do I choose the correct seat width?

Seat width is typically selected based on hip width plus typical clothing to support pelvic stability and comfort. After selecting width, seat depth, seat height and centre of gravity should be adjusted by an experienced person to match posture needs and riding style.

How does SIOUX differ from a fully custom active wheelchair?

A custom wheelchair is built around detailed individual measurements and a fully bespoke specification. SIOUX combines a rigid active-chair design with adjustable geometry and accessory options, offering a structured selection process and configuration flexibility without a full custom build.

Is SIOUX suitable for rehabilitation?

SIOUX can be used during rehabilitation when the goal is greater independence and transitioning to an active manual wheelchair. Adjustable seat position, seat depth and footrest height allow settings to be updated over time. Selection and setup should be consulted with a physician and/or physiotherapist.

Does SIOUX have brakes suitable for caregiver assistance?

SIOUX is equipped with rear wheel brakes with lock. If you require a specific caregiver-operated braking solution for your use case, suitability should be assessed during configuration with a qualified technician or supplier.

How do I transport SIOUX in a car?

SIOUX is not intended as a vehicle seat. The user should transfer to the car seat and fasten the seat belt. For transport, fold down the locking backrest and remove the rear wheels using the Quick Release axles, then secure the wheelchair to prevent movement in the trunk.

How should I clean and disinfect the wheelchair?

Clean the frame with a soft cloth dampened with water and a neutral cleaning agent, then dry thoroughly. Avoid strong acids, alkalis and abrasive agents. Disinfection should be performed according to the user manual (including recommended agents and concentrations). Regular inspection helps maintain safety and performance.
