Falls are the leading cause of injury deaths among older Australians, accounting for 70% of fatalities in people aged 65 and over. For many people with mobility limitations, a well-fitted rollator can be the difference between confidence and caution, between maintaining routines and restricting activities.

But with dozens of models available – from lightweight three-wheelers to heavy-duty bariatric options – how do you choose the right one? And more importantly, how do you know when it's time to move from a walking stick or walking frame to a rollator?

Quick Answers:

• Three-wheel rollators suit narrow spaces and tight turns indoors; less stable outdoors.

• Four-wheel rollators provide maximum stability, built-in seating, and are the most common choice.

• Key features include adjustable handle height, reliable brakes, appropriate wheel size, and comfortable seating.

• Weight capacity ranges from 100kg for standard models to 200kg+ for bariatric options.

• Proper fit requires handles at wrist height when arms hang naturally at sides.

Types of Rollators Available

Four-Wheel Rollators

The most popular style, and for good reason. Four wheels distribute weight evenly, providing excellent stability for both indoor and outdoor use. Most include a padded seat, backrest, and storage basket underneath. Four-wheelers typically feature two swivel wheels at the front for steering and two fixed wheels at the back. This design offers smooth movement without requiring much upper-body strength.

Three-Wheel Rollators

Lighter and more manoeuvrable than their four-wheeled counterparts, three-wheel models excel in tight spaces. They're ideal for navigating narrow hallways, small apartments, or crowded shops. The trade-off? Less stability. If you have significant balance concerns, a four-wheeler is usually safer.

Bariatric Rollators

Built with reinforced frames and wider seats, bariatric models support users up to 200kg or more. These aren't just about weight capacity, they also feature wider frames (typically 60-70cm) to accommodate larger body sizes comfortably.

All-Terrain Rollators

Designed for outdoor enthusiasts, these feature larger wheels (25cm+) and robust suspension systems. They handle grass, gravel, and uneven footpaths with ease. Perfect for those who want to maintain active lifestyles in parks or coastal areas around Melbourne.

Features That Matter

Handle Height and Adjustability

This is non-negotiable. When standing upright with arms relaxed at their sides, the handles should align with the user's wrist crease. Too low forces hunching; too high causes shoulder strain. Most rollators adjust between 80-95cm, but always verify the range matches your client's height.

Wheel Size

• 15cm or smaller: Indoor use, smooth surfaces, tight spaces

• 20cm: All-purpose, handles most footpaths and light outdoor terrain

• 25cm+: Outdoor use, uneven surfaces, gravel paths

Larger wheels roll more smoothly over obstacles but add weight and bulk. For someone who'll use their rollator walker with a seat primarily around the home, smaller wheels make more sense.

Brake Systems

Loop-lock hand brakes are standard and work like bicycle brakes – squeeze to slow, push down to lock. Test the pressure required. Someone with arthritis or reduced grip strength needs brakes that engage easily but won't slip.

Some models feature reverse braking systems (locked by default, squeeze to release). These suit people with cognitive impairment who might forget to engage traditional brakes.

Seat Comfort and Dimensions

If you plan to rest frequently, seat quality matters. Standard seat widths run 30-45cm, but measure the user's hip width while seated and add 5cm for comfort. Seat height is equally as important. Feet should plant flat on the ground when seated. Measure from the floor to the back of the knee while standing in regular shoes – this gives you the ideal seat-to-floor height.

Weight and Portability

Aluminium frames weigh 6-8kg; steel frames 10-12kg. If the rollator needs lifting into a car boot regularly, weight matters. Folding mechanisms vary too – some use one-hand releases, others require two hands. Have the user test this before purchasing.

Matching the Rollator to Individual Needs

For Indoor Use Primarily

Choose a narrower model (55-60cm width) with smaller wheels. Measure doorways first – most Australian homes have 80cm doorways, but some older homes or bathrooms run narrower. A three-wheel rollator often works well here.

For Outdoor and Mixed Use

Go with a four-wheel model featuring 20cm+ wheels. Look for robust tyres – EVA foam provides better shock absorption than hard plastic. A model with larger storage capacity helps with shopping trips.

For Travel

Prioritise lightweight construction (under 7kg) and easy folding. Some models fold completely flat; others just narrow slightly. Check car boot dimensions before purchasing.

For Cognitive Impairment

Consider reverse braking systems or models with simplified controls. Bright colours help with visibility and recognition.

When to Consider a Rollator Over Other Mobility Aids

There are multiple options for mobility aids, but a rollator best suits people who:

• Need consistent support for balance but can bear their own weight

• Walk distances where resting becomes necessary

• Require hands-free mobility (the basket allows this)

• Experience fatigue after walking 50-100 metres

If you need significant weight-bearing support, a standard mobility walking frame might be more appropriate. Conversely, if you only need minimal balance assistance and don't tire easily, an adjustable stick for walking could suffice.

Professional Assessment Makes the Difference

While understanding features helps narrow options, nothing replaces a proper assessment. At Back to Sleep, our team works alongside OTs, physios, and care managers across Melbourne to ensure clients receive disability aids Melbourne families can rely on. We offer trials, professional fittings, and advice backed by years of experience in mobility solutions.

Choosing the right rollator isn't about finding the most expensive model or the one with the most features. It's about matching specific needs to appropriate design, and that starts with taking accurate measurements, understanding how and where the rollator will be used, and ensuring proper fit from day one.
