Selecting a wheelchair is not simply a matter of picking a product off the shelf. A wheelchair is an extension of the user’s body—intended to provide comfort, promote independence, and support functional mobility. To achieve this, it must be properly fitted, appropriately styled, and tailored to the user’s physical and lifestyle requirements.
This guide outlines the core considerations in wheelchair selection and fitting. It is designed to equip buyers with the knowledge to make informed decisions when purchasing through Meditree.
1. Understanding Wheelchair Fitting: Why It Matters
A properly fitted wheelchair helps prevent:
- Poor posture
- Pressure injuries
- Limited mobility
- Transfer difficulties
- Upper body strain (especially in self-propelled users)
It also ensures:
- Proper weight distribution
- Improved propulsion efficiency
- Enhanced comfort and endurance
- Compatibility with indoor and outdoor environments
Incorrect sizing, even by a few centimetres, can lead to long-term issues such as scoliosis, shoulder impingement, and discomfort.
2. Core Body Measurements for Wheelchair Fit
Six body measurements form the foundation of a wheelchair fitting. These measurements should always be taken with the user seated upright, hips in a neutral position, and thighs parallel to the floor (ideally following the 90-90-90 posture rule: 90° at hips, knees, and ankles).
| Measurement | Purpose |
| Seat Width | Ensures hips and thighs are supported without being compressed |
| Seat Depth | Provides thigh support while preventing pressure behind the knees |
| Seat Height | Impacts transfers, leg positioning, and propulsion capability |
| Back Height | Affects trunk stability, shoulder mobility, and posture support |
| Armrest Height | Ensures forearm support without elevating or depressing shoulders |
| Footrest Length | Maintains proper leg angle and ground clearance |
Key Guidelines:
- Seat Width: Measure across the widest part of the hips or thighs. Allow 2–4 cm of clearance.
- Seat Depth: From the base of the spine to just behind the knee. Leave approx. 3 finger-widths at the front.
- Seat Height: Heel to back of knee, adjusted based on footrest or foot propulsion.
- Back Height: From seat to either below the scapula (active users) or up to the neck (postural support needed).
- Armrest Height: With forearms resting, measure vertically from seat to elbow.
- Footrest Length: Based on leg length; footrests should clear the floor by about 5 cm (2 inches).
3. Choosing the Right Wheelchair Type Based on Use
The correct type of wheelchair depends on the user’s functional mobility, level of independence, and support requirements.
| Type | Description | Ideal User Profile |
| Manual Wheelchair | Large rear wheels for self-propulsion, foldable frame | Users with good upper body strength |
| Transport Wheelchair | Small rear wheels, requires caregiver to push | Part-time users, short-distance transport |
| Power Wheelchair | Battery-operated, joystick-controlled | Users with limited upper limb function or fatigue |
| Active User Wheelchair | Lightweight, compact, responsive; designed for frequent propulsion | Independent users with good balance and coordination |
| Bariatric Wheelchair | Reinforced frame, wider seat, higher weight capacity | Users over 120 kg or with broader body frames |
| Pediatric Wheelchair | Custom fit for children; safety-focused with growth adjustability | Children with mobility impairments |
4. Seating Systems: Style, Support and Adjustability
Seat Shape and Materials
- Flat Seats: Standard option; may require a cushion for comfort or pressure relief
- Contoured Cushions: Improve posture and reduce pressure points
- Gel, Foam, or Air Cushions: Vary based on comfort, weight distribution, and skin integrity needs
Backrests
- Low Backrest: Allows shoulder freedom; common for active users
- High Backrest: Required for poor trunk control or postural instability
- Reclining or Tilt-in-Space: Assist with pressure relief and postural support in complex needs
Armrests and Leg Supports
- Desk-Length Armrests: Allow closer positioning to tables
- Full-Length Armrests: Offer full forearm support
- Swing-Away Legrests: Improve transfer ease and adaptability
- Elevating Legrests: Support for edema management or post-operative positioning
5. Adjustability vs. Fixed Frames
Adjustability is critical in many modern wheelchairs, especially for long-term users or those with evolving needs.
| Feature | Fixed Frame | Adjustable Frame |
| Back height | One standard height | Can be adapted to user needs |
| Seat angle/tilt | Static | Allows tilt-in-space or recline |
| Arm/leg rest height | Often fixed | Easily changed without tools |
| Footrest positioning | Pre-set | Adjustable for growth or changing requirements |
Adjustable models may have a slightly higher upfront cost but deliver significant value in terms of comfort, support, and lifespan.
6. Consider the User’s Environment
Wheelchairs should be selected with their primary usage environment in mind.
| Use Case | Recommended Features |
| Indoor Use | Narrow frame, tight turning radius, standard seat height |
| Outdoor Use | Larger wheels, puncture-resistant tyres, reinforced frame |
| Travel Use | Lightweight frame, easy folding, removable components |
| Home Care Setting | Compatibility with bed heights, transfer aids, and doorways |
