Choosing a wheelchair is one of the most important mobility decisions you’ll make. Get it right and it opens up your world, wrong, and it can lead to discomfort, pain, and unnecessary expense. Whether you’re buying for yourself or someone you care for, this guide walks you through everything you need to consider before making a decision.
Start Here: Get a Professional Assessment
Before comparing models or prices, the single most valuable thing you can do is consult with an Occupational Therapist (OT) or a Physiotherapist (PT) who specialises in seating and positioning. This is not optional box-ticking, it genuinely changes outcomes.
A qualified therapist will assess:
- Posture and postural support needs, what the spine, pelvis, and head require to stay properly supported throughout the day
- Body measurements, seat width, depth, and height tailored to your body, not a generic size chart
- Pressure management, which cushion technology suits your skin sensitivity and how long you’ll be sitting
- Strength and stamina, whether you can realistically self-propel, and for how long
Many people skip this step to save time, only to find the chair they purchased doesn’t work for them. A proper assessment prevents that.
Manual or Power: The First Big Decision
This is the fork in the road. Everything else branches from it.
| Manual Wheelchair | Power Wheelchair | |
|---|---|---|
| Best for | Users with good upper body strength, or those with a caregiver | Users with limited strength, fatigue, or conditions affecting arm function |
| Independence | Requires physical effort to self-propel | Joystick or alternative controls; minimal physical effort |
| Portability | Generally lighter and foldable, fits in most car boots | Heavy; often requires a vehicle ramp or adapted transport |
| Maintenance | Low, mostly tyres and brakes | Higher, batteries, motors, and electronics require attention |
| Cost | More affordable to purchase and maintain | Higher upfront and ongoing costs |
A middle-ground option worth knowing about: power-assist attachments. These bolt onto a manual wheelchair and provide a motorised boost when needed, useful if you can self-propel on flat surfaces but struggle on slopes or over longer distances.
Types of Wheelchairs Explained
Once you’ve settled on manual or power, you’ll encounter several categories within each. Here’s what they mean in practice.
Manual Wheelchairs
Standard / Transit Wheelchairs These have smaller rear wheels and are designed to be pushed by a caregiver. They’re lighter and often more compact, making them good for hospitals, recovery periods, or outings where a caregiver is always present. Not suitable for self-propulsion.
Lightweight Self-Propelling Wheelchairs The most common choice for everyday independent users. They’re foldable, reasonably priced, and come in a range of seat widths. A good option if you have adequate upper body strength and want to get around on your own.
Active / Ultra-Lightweight Wheelchairs Built from high-grade aluminium or titanium, these chairs are for people who use a wheelchair full-time and want maximum performance. They’re highly customisable, energy-efficient to push, and often built to the user’s exact measurements. Rigid-frame versions are more efficient than folding frames, they don’t flex, so less energy is lost with each push.
Paediatric Wheelchairs Scaled and adapted for children, with adjustable components to accommodate growth. Available in both manual and powered options.
Complex / Custom Seating Wheelchairs For users with significant postural needs, cerebral palsy, muscular dystrophy, spinal injuries, and similar conditions. These include tilt-in-space, reclining backrests, and extensive positioning accessories. Always require therapist involvement.
Power Wheelchairs
Standard Power Wheelchairs Joystick-controlled, suitable for indoor and outdoor use. Good for users who need motorised assistance for full-time mobility.
Rear-Wheel vs Mid-Wheel vs Front-Wheel Drive This affects how the chair handles. Mid-wheel drive offers the tightest turning radius, important for indoor use. Rear-wheel drive handles outdoor terrain better. Discuss this with your therapist or supplier.
Power Chairs with Tilt and Recline These offer pressure relief and repositioning without needing to transfer out of the chair. Particularly important for users who spend extended hours seated.
Getting the Size Right
Poor fit is the most common cause of wheelchair-related pain and pressure injuries. These are the measurements that matter most:
Seat Width Should be slightly wider than the widest part of your hips, typically 2–3 cm on either side. Too wide and you’ll struggle to reach the wheels; too narrow and it puts pressure on your hips.
Seat Depth Measured from the back of the seat to behind the knee. There should be a gap of about 4–5 cm between the seat edge and the back of your knee. Too deep cuts off circulation; too shallow doesn’t give enough thigh support.
Seat Height Your feet should rest flat on the footrests without your knees being forced upward or your hips tilting. This also affects how well the chair fits under tables and desks.
Backrest Height A lower backrest allows more upper-body movement and is preferred by active users. A higher backrest provides greater trunk support, important for users with limited core strength.
Weight Capacity Always check this. Standard chairs typically handle up to around 120 kg. Bariatric or heavy-duty models are rated for significantly more. Never use a chair rated below your weight.
Where Will You Use It?
This shapes what features matter most.
Primarily indoors Focus on a tight turning radius. A narrower frame and smaller front casters help with hallways, bathrooms, and doorways. Measure the narrowest doorway in your home before committing to a width.
Outdoors and on varied surfaces Larger front casters and pneumatic (air-filled) tyres handle uneven pavement, gravel, and grass far better than small solid tyres. Consider a chair with slightly larger rear wheels too.
Frequent travel or transport If the chair will go in and out of a car regularly, weight and foldability matter enormously. A chair that folds flat and weighs under 12 kg makes a real difference over time, both for the user and for anyone helping load it.
Key Components to Evaluate
Cushion Do not overlook this. A quality cushion, gel, foam, or air, reduces the risk of pressure sores significantly for anyone spending more than a couple of hours in the chair. The standard sling seat that comes with most basic chairs is rarely adequate for long-term use.
Armrests Desk-length armrests allow you to pull closer to tables. Flip-back or removable armrests make transferring in and out of the chair much easier. Consider which matters more in your daily routine.
Footrests Swing-away footrests fold to the side, making it easier to stand or transfer. Fixed footrests are lighter but less flexible. Elevating footrests are useful for users who need to keep their legs raised.
Brakes Check that the brakes engage firmly and are easy to reach. Some users with limited hand strength may need extended brake levers.
Wheel camber (manual chairs) Camber refers to the outward angle of the rear wheels. A slightly cambered wheel increases stability and makes turning easier, but adds overall width. Common in active and sports chairs.
Wheelchair Prices: What to Expect in South Africa
Wheelchair prices in South Africa vary widely depending on the type, brand, and whether it’s manual or powered. Import costs and exchange rates mean prices can shift, so treat the ranges below as a general guide rather than fixed figures. Always get a current quote from your supplier.
| Wheelchair Type | Approximate Price Range | Notes |
|---|---|---|
| Standard / Transit (manual) | R1,500 – R5,000 | Basic caregiver-pushed chairs; economy to mid-range |
| Lightweight Self-Propelling | R3,000 – R10,000 | Everyday folding chairs for independent users |
| Active / Ultra-Lightweight | R15,000 – R60,000+ | Custom-built, titanium or aluminium; long-term users |
| Paediatric | R4,000 – R40,000+ | Wide range depending on complexity and adjustability |
| Standard Power Wheelchair | R25,000 – R80,000 | Entry to mid-range electric chairs |
| Complex / Custom Power Chair | R80,000 – R200,000+ | Tilt, recline, and full postural support features |
Prices are approximate and subject to change. Used wheelchairs can offer significant savings, see the section below.
A Note on Used Wheelchairs
Everything covered in this guide applies equally when buying a used wheelchair. The same fit, features, and suitability questions matter, arguably more so, because a chair that doesn’t fit correctly will cause problems whether it’s new or second-hand. Used wheelchairs can bring quality chairs into reach at a fraction of new wheelchair prices, but only if you know what to check.
The additional layer with used chairs is condition. Before buying, it’s worth knowing what to inspect and what warning signs to look for. We’ve put together a dedicated guide on this: Buying a Used Wheelchair: What to Check Before You Pay.
Summary: Questions to Answer Before You Buy
Run through these before committing to any chair:
- Has a therapist assessed my postural and seating needs?
- Manual or power, which suits my strength, stamina, and lifestyle?
- What are my correct seat measurements?
- Where will I primarily use this chair, indoors, outdoors, or both?
- Will it need to fit in a car, and how often?
- What is the weight capacity, and does it exceed my weight?
- Do I need swing-away footrests, desk-length armrests, or other specific components?
- Have I factored in a quality cushion?
Getting these answers right, ideally with professional guidance, puts you in a much stronger position to choose a chair that genuinely works for you, not just one that looks right on paper.
