Finding the right wheelchair when standard models aren't built for your frame can feel frustrating. A bariatric wheelchair is designed for people who exceed the weight limits of standard chairs, typically those over 130 kg, and in Australia the range of options has improved a lot in recent years. This guide walks you through what to look for and how to choose the right model with confidence.
What Is a Bariatric Wheelchair?

A bariatric wheelchair is a wider, stronger chair built to safely support people over 130 kg. Standard wheelchairs are typically rated to 120 kg. Bariatric models start from 150 kg capacity and go up to 300 kg or more for specialist heavy-duty designs. The wider frame also gives you more room to sit comfortably and reduces the pressure of the armrests against your hips and thighs.
Weight Capacity Options in Australia
In Australia, you will generally find three tiers of bariatric wheelchairs:
- 150 to 180 kg capacity: entry-level bariatric, a good fit for most people who exceed the standard 120 kg limit
- 200 kg capacity: mid-range heavy duty, the most commonly stocked option and suitable for users up to 200 kg
- 250 to 300 kg capacity: specialist heavy duty; these are less common off the shelf and are often made to order

Seat Width and Dimensions
Bariatric wheelchairs typically come in seat widths of 50 cm, 55 cm, and 60 cm, compared to 40 to 46 cm for standard models. The right width should give you 2 to 3 cm of clearance on each side of your hips. Too wide and you cannot reach the wheels comfortably; too narrow and the armrests press against your thighs.
Frame and Build Quality: What to Look For

Reinforced Steel vs Heavy-Duty Aluminium
Most bariatric wheelchairs use reinforced steel frames, which deliver the strength you need at a more affordable price. Steel is heavier, typically 20 to 30 kg for a bariatric model, which makes transporting it more demanding. Heavy-duty aluminium bariatric frames are available and sit around 15 to 20 kg, but they come at a higher price. If the chair will mostly be used indoors and does not need to be lifted often, a steel frame is the practical, economical choice.
Folding vs Fixed Frame
Most bariatric wheelchairs use a cross-brace fold for portability. Fixed (rigid) frames exist in bariatric sizes but are far less common. For most people, a folding bariatric chair is the right call. It stores more easily and fits in most vehicle boots with the rear footrests removed.
Finding the Right Bariatric Wheelchair for Your Needs

Measuring Correctly

Getting the measurements right matters more with bariatric wheelchairs, because fitting issues are harder to adjust after you have placed your order. Measure seat width (your hip width plus 3 cm clearance on each side), seat depth (from the back of your buttocks to behind the knee), and seat height. If your waist-to-floor measurement falls outside the standard footrest range, check that the model you are considering has adjustable footrests. We recommend reading our full guide on how to measure for a wheelchair before ordering.
Funding Through NDIS or DVA
Bariatric wheelchairs are eligible for funding under the NDIS Assistive Technology budget and through DVA for eligible veterans. Because these models have more specific fitting requirements, an occupational therapist assessment is especially valuable before you buy. Your OT can confirm the chair you order matches your clinical needs and supports your NDIS plan goals. We recommend speaking with your plan manager or OT before committing to a specific model.
Key takeaways:
- Bariatric wheelchairs are designed for people over 130 kg, with capacities from 150 kg to 300 kg
- Seat width should give you 2 to 3 cm of clearance on each side of your hips
- Reinforced steel frames are the most affordable; heavy-duty aluminium is lighter but costs more
- NDIS and DVA can fund bariatric models; an OT assessment before ordering is well worth it
