Most people arrive at this decision without warning. A fall, a diagnosis, a hip replacement, or the slow realisation that a parent is no longer steady on their feet. Suddenly you are looking at a category with dozens of product types, a lot of overlapping terminology, and no obvious starting point.
The good news is that the decision is more structured than it looks. Mobility aids form a ladder, from a cane that provides a little extra stability through to a powered chair that does the moving entirely. Working out which rung you need is the whole exercise, and it comes down to a handful of honest questions about balance, endurance, upper body strength and where the equipment will actually be used.
Who This Guide Is For
Anyone buying a mobility aid for themselves, adult children arranging equipment for a parent, caregivers and family members, discharge planners and case managers, and occupational or physical therapists helping a client compare options.
What This Guide Covers
The support ladder from canes to power chairs, how to identify which level you need, the differences between walkers and rollators, manual wheelchairs and transport chairs, and power wheelchairs and scooters, plus sizing, weight capacity, home access and Medicare basics. This is educational content and not medical advice; a physical or occupational therapist should confirm the choice.

The Support Ladder
Every mobility aid sits somewhere on a single scale: how much of the work the equipment does, and how much the person does.
| Level | Equipment | The Person Still Does |
|---|---|---|
| 1 | Cane or walking stick | Walks, with a third point of contact |
| 2 | Walker or rollator | Walks, with a frame taking some weight |
| 3 | Manual wheelchair | Propels with arms, or is pushed |
| 4 | Transport chair | Sits; a caregiver does the moving |
| 5 | Scooter, power or tilt wheelchair | Steers; the motor does the moving |
Two things worth saying about this ladder before going further.
Higher is not better. The right aid is the least amount of assistance that keeps the person safe. Using more support than necessary accelerates deconditioning: muscles that are not used weaken, and balance that is not practised deteriorates. A person put into a wheelchair who could manage a rollator will often need the wheelchair permanently within a year.
Most people end up with two. A rollator for around the house and a transport chair for long outings. A cane indoors and a scooter for the shops. Buying one device to cover every situation usually means it suits none of them well.
Which Rung Do You Need?
Four questions get you most of the way there. Answer them honestly rather than optimistically, and involve a physical or occupational therapist if there is any doubt.
1. Is the problem balance, or is it endurance? Someone who feels unsteady but can walk a reasonable distance needs stability, which points to a cane or walker. Someone who is steady but exhausted after fifty metres needs to conserve energy, which points to a rollator with a seat or a wheeled option.
2. Can they bear weight on both legs? If yes, walking aids remain on the table. If one leg cannot take weight, crutches or a knee scooter suit a temporary recovery, and a wheelchair suits anything longer.
3. What is the upper body like? Self-propelling a manual wheelchair takes real shoulder and arm strength, sustained over a whole day. If that is not there, the choice is between being pushed in a transport chair or moving independently in a powered chair.
4. Who else is around? A transport chair needs somebody to push it. If the person is often alone, that is not a solution regardless of how well it suits them otherwise.
Canes and Walking Sticks
The lightest intervention, and often underrated. A cane provides a third point of contact, shifts a portion of load away from a painful joint, and gives useful sensory feedback about the ground.
Three things separate a useful cane from a frustrating one. Height is the big one: with the person standing upright in their usual shoes, arms hanging naturally, the handle should sit level with the crease of the wrist. Too tall and the shoulder hunches; too short and they lean forward. Base type matters next: a single point suits general support, while a quad or pivoting base adds stability for someone with more significant balance issues. And whether it folds decides whether it gets used, because a cane that will not stow in a bag gets left at home.
One detail that sounds trivial and is not: a cane is used on the opposite side to the weaker leg, so the arm and the leg work as a pair. A surprising number of people are never told this and use it on the wrong side for years.
Walkers and Rollators
The next rung, and the one where the terminology causes the most confusion. Both provide a frame in front of the user; the difference is wheels and what they do to the interaction.
A standard walker has four rubber-tipped legs and no wheels. The user lifts it, places it, then steps to it. That sounds laborious and it is the point: the frame is completely stationary while they move, which is the most stable arrangement available short of a wheelchair. It suits someone with significant balance impairment who moves slowly and deliberately.
A two-wheel walker adds front wheels so the frame can be pushed rather than lifted, trading a little stability for considerably less effort.
A rollator has four wheels, hand brakes and a seat. It does not need lifting at all, it moves at walking pace, and the seat means the user can stop and rest anywhere. That last feature is what changes lives: someone whose limit is a hundred metres can suddenly manage a whole shopping trip in stages.
The trade-off is real and worth stating. A rollator rolls, which is exactly what you do not want if the user is inclined to lean on it heavily for support. Brakes have to be applied deliberately before sitting, and a person with cognitive impairment may not do that reliably. For that user, a standard walker is safer despite being more effort.
Practical selection points: wheel size of 8 inches or more for outdoor use, since small wheels catch on pavement edges and thresholds; brake type, with loop brakes suiting most people and push-down brakes suiting weaker hands; and folding width, which decides whether it goes in the car boot.
A note on temporary recovery. If one leg cannot bear weight after a foot or ankle procedure, the situation is different from a permanent mobility limitation. Crutches are the traditional answer and work well for someone with good upper body strength and balance, though they tire the shoulders and occupy both hands. A knee scooter takes the weight on the shin of the affected leg while the person propels with the good one, which is considerably less tiring over weeks and leaves the hands freer. Neither suits someone with poor balance or bilateral weakness, where a wheelchair is the safer choice for the recovery period.
Manual Wheelchairs
When walking is not practical for the distances involved, a manual wheelchair keeps the user independent provided they have the upper body strength to propel it.
Frame weight is the specification that affects daily life most, and it is not about the user. It is about whoever lifts the chair into a car boot several times a week. A standard steel wheelchair and an ultra-lightweight aluminium one differ by enough that one gets used and the other stays in the hallway.
Fixed or swing-away footrests is the other decision people underestimate. Swing-away footrests move out of the path during transfers, which for someone getting in and out several times a day is the difference between an easy transfer and a barked shin. They also detach, reducing the weight to lift.
Sizing deserves its own attention and is covered in detail in our wheelchair sizing guide.
Reclining and Tilt-in-Space Wheelchairs
A category that gets overlooked until it becomes essential. Standard wheelchairs hold the user in one posture. Reclining and tilt-in-space chairs change that posture through the day, and for someone sitting for extended periods the difference is clinical rather than cosmetic.
The two are not the same thing, and the distinction matters.
A reclining wheelchair opens the angle between the backrest and the seat. The back goes down while the seat stays level. This relieves pressure, allows rest without transferring to a bed, and helps with breathing and digestion for some users. The trade-off is that opening the hip angle encourages the body to slide forward down the seat, and sliding is shear, which damages tissue at the sacrum.
A tilt-in-space wheelchair rotates the whole seating position as a single unit, keeping the hip and knee angles fixed while tipping the user backward. Because the posture does not change, the person does not slide. What changes is where the load falls: weight shifts from the ischial tuberosities toward the back, redistributing pressure across a larger area without introducing shear.
The practical rule: if the user slides forward in a reclining chair, or has sacral skin concerns, tilt-in-space addresses the mechanism that recline does not. Tilt is also the answer for someone with poor trunk control who needs to be held in a stable posture rather than settling into whatever position gravity produces.
Both categories matter for pressure injury prevention, and anyone sitting for most of the day should be using a pressure-redistributing cushion alongside. Our pressure injury prevention guide covers the underlying mechanism, and our clinical care recliners guide covers the same principles applied to seating outside a wheelchair.
Transport Chairs and the Duet Option
A transport chair looks like a wheelchair with small wheels all round, and that difference tells you everything about it. Small rear wheels mean the user cannot reach them to self-propel, so somebody else always pushes. In exchange it is lighter, narrower and folds smaller.
It suits a specific pattern: someone who walks at home but cannot manage the distances involved in a hospital visit, an airport, or a day out. It is not a full-time wheelchair and using it as one removes the person's independence entirely.
The Duet shown above is worth understanding because it solves the two-device problem in one frame. Used as a rollator, the person walks behind it with the seat available for rests. When they tire, the backrest flips over, footrests deploy, and a caregiver pushes them home in it as a transport chair. For a household that would otherwise buy a rollator and a transport chair, and store both, this is a genuinely practical answer.
The compromise is that a combination device is slightly heavier than a dedicated rollator and slightly less refined than a dedicated transport chair. Whether that matters depends on how often each mode gets used.
Power Wheelchairs and Scooters
At the top of the ladder, a motor does the moving. This is the right answer when distance or endurance is the limiting factor and self-propelling is not realistic.
Powered equipment introduces considerations that manual equipment does not: battery range, charging routine, weight, and how the thing travels when the user does. The Phoenix Max LE illustrates where that category has gone, using carbon fiber to bring the weight down far enough that a folded power chair becomes something one person can lift, and it is airline approved for travel.
The Afiscooter C4 represents the other end: a full-size four-wheel scooter built for outdoor range and comfort over distance rather than for portability. For someone whose problem is getting around a town rather than around a house, this is the appropriate shape.
Power Wheelchair or Scooter?
These get compared constantly and they suit different people, which is easy to see once you look at how each is controlled.
A scooter is steered with a tiller, using both hands, and the user sits on a captain-style seat. That requires reasonable trunk control, the ability to sit upright unsupported, enough hand and arm function to steer, and the ability to get on and off. It has a wide turning circle, which makes it excellent outdoors and awkward in a narrow hallway.
A power wheelchair is controlled with a joystick using one hand, and the seating provides postural support. It turns in a much tighter space, often on its own axis, which makes it viable indoors. It suits someone with less trunk control, less hand function, or a need for supportive seating.
The practical test: if the person can walk short distances and the issue is range, a scooter usually fits. If the person cannot walk and needs the chair as a seating system for most of the day, a power wheelchair is the right category.
There is also a coverage dimension. Medicare treats these differently, and a scooter is generally assessed on whether the person can use it safely and whether it meets a need within the home, which is a different test from a power wheelchair. Our Medicare Part B guide covers the framework, and our manual versus power comparison goes deeper on the chair side.
Choose the device around daily life rather than around the diagnosis alone. Turning radius, seat width and whether one person can load it into a car will affect quality of life more than the specification sheet suggests.

Sizing: The Measurements That Matter
An ill-fitting device causes problems that look like the person being difficult and are really equipment mismatch.
Seat width is measured across the widest point of the hips while seated, plus roughly an inch either side. Too narrow creates pressure at the hips and makes transfers hard. Too wide removes lateral support, so the person leans and loads one side, and the extra width may not fit through a doorway.
Seat depth runs from the back of the buttocks to the back of the knee, less about two inches. Too deep and the front edge presses behind the knee, restricting circulation and encouraging a slide forward. Too shallow and thigh support is lost.
Seat to floor height determines whether feet reach the footplates comfortably and whether the person can foot-propel if they do that.
Handle height on a walker or rollator should put the handle at wrist crease level with arms hanging, the same rule as a cane, giving a slight elbow bend in use.
If the person constantly slides forward, leans to one side, or refuses to use the equipment, check the fit before concluding it is a behavioural problem. Our sizing guide covers the measurements in detail.
Will It Work in the Home?
The most common reason a mobility aid ends up unused is that it does not fit the environment it was bought for.
Doorway width. Measure the narrowest doorway the device must pass, at the narrowest point with the door open. Interior doors are frequently 30 to 32 inches, and a standard wheelchair plus hands needs most of that.
Turning space. Corridors and bathrooms are where devices get stuck. A scooter with a wide turning circle may enter a room and be unable to turn around in it.
Thresholds and steps. Even a small lip stops small wheels. Threshold ramps solve most of these cheaply.
Flooring. Thick carpet significantly increases the effort of self-propelling a manual chair and reduces the range of a powered one.
Storage and charging. A powered device needs somewhere to live near an outlet. A folded rollator needs somewhere it will not be a trip hazard.
Transport. If the device travels by car, check the folded dimensions against the boot, and check who lifts it and whether they can.
Weight Capacity and Bariatric Options
Every device carries a stated weight capacity and it is a structural limit rather than a suggestion. Exceeding it risks frame failure and voids the warranty.
Standard wheelchairs and rollators commonly rate around 250 to 300 lb. Bariatric versions extend well beyond that, with heavy duty wheelchairs available at 400 lb, 500 lb and higher, built on reinforced frames with wider seats and stronger axles.
Three points that get missed.
Width rises with capacity. A bariatric wheelchair rated to 500 lb is considerably wider than a standard one, and that width has to clear the narrowest doorway in the home. Measure the doorway before choosing the chair, not after. This is the single most common reason a correctly specified bariatric chair ends up unusable.
Lightweight bariatric exists. Heavy duty frames were traditionally steel and very heavy, which created a second problem: nobody could lift the chair into a car. Lightweight bariatric options now bridge that gap, and if the chair travels regularly it is worth the difference.
Every item in the chain has its own rating. If the person also uses a transfer aid, a commode, a shower chair or a hospital bed, each carries its own limit and the lowest one governs the whole setup. A 500 lb wheelchair paired with a 300 lb commode is a 300 lb arrangement. Our bariatric hospital beds guide covers the same principle on the bed side.
Will Medicare Pay for It?
Sometimes, and the answer depends on the equipment type and the documentation rather than on the diagnosis alone.
Medicare Part B covers durable medical equipment when a physician documents that it is medically necessary for use in the home. That last phrase does a lot of work: the assessment centres on whether the person needs the equipment to move around inside their own home, not on whether it would help them get to the shops.
Canes, walkers and rollators sit at the simpler end. Wheelchairs and powered mobility face progressively more documentation, and powered equipment generally requires a face-to-face examination with the prescribing clinician specifically addressing mobility.
Two practical points. The documentation has to exist before the claim, not be assembled afterwards. And the supplier matters, since coverage generally applies through enrolled suppliers rather than to equipment bought independently.
Our Medicare Part B guide for mobility aids covers this properly, and for anything not covered, our financing guide and the financing options at checkout may help.
Accessories That Actually Help
Accessories can meaningfully improve daily use, though it is worth separating the ones that solve a real problem from the ones that simply sell.
Cushions are the accessory that matters most and gets bought least. Anyone sitting for extended periods is loading the ischial tuberosities over a small area, and a proper pressure-redistributing cushion is part of skin protection rather than a comfort upgrade. Our pressure injury prevention guide explains the mechanism.
Anti-tip devices on wheelchairs prevent backward tipping when going up a slope or reaching behind.
Bags and baskets sound trivial and are not: someone using both hands on a rollator has no way to carry anything, which is a genuine barrier to independent shopping.
Threshold ramps resolve the small steps that stop a device at a doorway.
Cane and crutch tips wear out and lose grip. They are inexpensive and replacing them on schedule is basic safety.
For keeping everything in working order, see our maintenance guide.
Mistakes That Repeat
Buying more support than needed. It accelerates deconditioning. Choose the least assistance that keeps the person safe.
Buying one device for every situation. Most people are better served by two devices suited to different contexts.
Not measuring the doorways. The single most common reason equipment goes unused.
Ignoring who lifts it. Frame weight matters to the caregiver loading a car, not to the user sitting in it.
Skipping the cushion. Extended sitting without pressure management is a skin injury waiting to happen.
Guessing the seat width. Measure the hips. A chair two inches too wide will not fit the bathroom door.
Choosing a rollator for someone who leans heavily. It rolls. For a user who cannot reliably apply brakes, a standard walker is safer.

Frequently Asked Questions (FAQ)
Q1: How do I know which mobility aid I need?
Start with four questions: is the problem balance or endurance, can the person bear weight on both legs, is there upper body strength to self-propel, and is a caregiver usually present. Balance issues point to canes and walkers, endurance limits point to rollators and powered options, and no weight bearing points to a wheelchair. A physical or occupational therapist should confirm the choice.
Q2: What is the difference between a walker and a rollator?
A standard walker has four rubber-tipped legs and is lifted and placed with each step, which is the most stable arrangement. A rollator has four wheels, hand brakes and a seat, so it moves at walking pace and lets the user rest anywhere. Rollators suit endurance limits; standard walkers suit significant balance impairment.
Q3: What is the difference between a wheelchair and a transport chair?
A wheelchair has large rear wheels the user can reach to self-propel. A transport chair has small wheels all round, so somebody else always pushes it. Transport chairs are lighter and fold smaller, which suits outings, but using one full time removes the person's independence.
Q4: Should I get a mobility scooter or a power wheelchair?
A scooter is steered with a tiller and needs trunk control, hand function and the ability to get on and off; it excels outdoors and turns poorly indoors. A power wheelchair uses a joystick, provides postural support and turns tightly enough for indoor use. If the person can walk short distances and the issue is range, a scooter usually fits. If they need the chair as seating for most of the day, a power wheelchair does.
Q5: Which side should a cane be used on?
On the opposite side to the weaker leg, so the cane and the affected leg move together as a pair. Height should put the handle level with the crease of the wrist when standing upright with arms hanging naturally.
Q6: Does Medicare cover mobility aids?
Medicare Part B may cover durable medical equipment where a physician documents it is medically necessary for use in the home. That assessment centres on movement inside the home rather than outdoor activity. Powered mobility generally requires a face-to-face examination addressing mobility, and documentation must be in place before the claim.
Q7: How do I measure for the right size?
Seat width is hip width at the widest point plus about an inch either side. Seat depth is buttock to back of knee, less about two inches. For canes, walkers and rollators, handle height should sit at the wrist crease with arms hanging. Check the result against your narrowest doorway before ordering.
Q8: Is a lighter wheelchair worth the extra cost?
Usually, if it goes in a car. Frame weight matters most to whoever lifts the chair into a boot several times a week rather than to the person sitting in it. A chair that is too heavy to load reliably ends up unused.
Q9: Do I need a wheelchair cushion?
If the person sits for extended periods, yes. Sitting concentrates body weight on a small area over the ischial tuberosities, and a pressure-redistributing cushion is part of skin protection rather than a comfort extra. It is the most commonly skipped accessory that genuinely matters.
Q10: What is the difference between a reclining and a tilt-in-space wheelchair?
A reclining wheelchair opens the angle between backrest and seat, which relieves pressure and allows rest but encourages the body to slide forward, creating shear at the sacrum. A tilt-in-space chair rotates the whole seated posture as one unit, keeping hip and knee angles fixed, so the person does not slide while load shifts away from the ischial tuberosities. If the user slides forward or has sacral skin concerns, tilt is the answer.
Q11: Does MediDepot carry the full range of mobility aids?
Yes, including canes and crutches, standard walkers and rollators, manual and lightweight wheelchairs, transport chairs, bariatric options, power wheelchairs and mobility scooters, plus cushions and accessories. Browse: Mobility Aids at MediDepot.
