Features and functions

Built for real life

What stands out

Omni-directional front wheels

Each front wheel carries 10 compact rollers, so the chair slides sideways into a turn instead of swinging wide. The turning radius is 29.9".

3" of ground clearance

Four independently sprung wheels and a 2" obstacle rating, so grass, gravel and a raised threshold are all within its ground.

Three seat sizes

16" W X 16" D, 18" W X 18" D and 20" W X 18" D, all at the same price, with the seat height adjustable from 15.9" to 19.1".

Separates for a car

It comes apart by hand into four parts. The heaviest piece is the rear drive base at 42.8 lbs.

Airline approved battery

The 6 lbs. lithium battery is approved for air travel and charges in about 5 hours.

The Hieline Take

The Model C2 is the chair to look at when the same machine has to work indoors and outdoors. The omni-directional front wheels are the reason: each one carries 10 compact rollers, so the chair moves diagonally into a turn and gets around a 29.9" radius without a three-point turn, which very few outdoor-capable chairs manage. Then it steps outside on 3" of ground clearance, four independently sprung wheels and a 2" obstacle rating, so grass, gravel and a raised threshold are all within its ground. The honest caveats are three. It is heavy to move by hand at 114 to 116.4 lbs., and although it disassembles into four parts, the heaviest piece is still 42.8 lbs., so it is a two-person lift for most people. The colour you pick is the arm cover and nothing else, because the frame is black on every one. And the 5 mph top speed applies where local rules allow it, otherwise the chair is set to 3.7 mph. If you want a chair you can fold in one motion and lift alone, the Model F weighs 58.9 lbs. and folds, and it gives up the ground clearance to do it.

Straight talk

Is it right for you?

A good fit if you

  • need one chair for indoors and outdoors, it has 3" of ground clearance and clears a 2" obstacle
  • turn in tight rooms and shop aisles, the turning radius is 29.9"
  • weigh up to 300 lbs. and want a choice of a 16", 18" or 20" wide seat
  • fly with your chair, the lithium battery is airline approved

Look elsewhere if you

  • need to fold a chair in one motion and lift it alone, the Model F folds and weighs 58.9 lbs.
  • want the frame itself in a colour, the colour on this chair is the arm cover and the frame is black
  • need more than 300 lbs. of capacity
  • want a power elevating seat, this chair does not offer one

Getting the size right

Not sure it will fit you?

Five measurements, taken at home with a tape and a firm chair, tell you whether a seat will suit you. The guide opens right here with a printable worksheet.

How to measure for a wheelchair

How to measure for a wheelchair

Getting the right wheelchair starts with getting the right fit. A chair that is too wide, too narrow, too deep or too short is uncomfortable and hard to use.

You do not need dozens of measurements to get started. For most manual wheelchairs, transport chairs and power wheelchairs, the five below will get you to the right size.

C is lower leg length, from the crease behind the knee to the bottom of the heel. D is back height, from the seat surface to the top of the backrest. E is elbow height, from the seat surface to the underside of the elbow.DBCE

Before you measure

Sit upright in a firm chair. Wear the shoes and the clothing you expect to use with the wheelchair. Have someone help you, because the measurements are far more accurate when somebody else holds the tape.

  1. Measurement A. Hip width

    Measure the widest part of your hips or thighs while seated. Keep the tape straight across your body rather than wrapping it around you.

    This is the measurement that points you at a seat width.

    Leave yourself a little room. If your seated hip width is about 19", look at a seat that gives you a small amount of clearance rather than one measuring exactly 19".

    Do not go wider than you need. A wider seat makes the whole wheelchair wider, and that makes doorways and indoor turns harder.

  2. Measurement B. Seat depth, also called upper leg length

    Measure from the back of your buttocks to the crease behind your knee while seated.

    The front edge of the seat should never press against the back of your knees. Aim for about 1" to 2" of space between the seat edge and the back of the knee.

    A seat that is too deep presses behind the knees. A seat that is too shallow leaves your thighs without support.

  3. Measurement C. Lower leg length

    Measure from the crease behind your knee down to the bottom of your heel, wearing your normal shoes. Keep your knee bent at about 90 degrees.

    This one tells you about seat-to-floor height, footrest height, legrest adjustment and footplate position.

    If the wheelchair comes with a cushion, remember the cushion raises your seated height.

  4. Measurement D. Back height

    Sitting upright, measure straight up from the seat surface to where you want the top of the backrest to sit.

    The right back height depends on how much upper-body support you need. A lower back gives an active manual wheelchair user more freedom to move. A higher back gives more trunk and upper-body support.

    If you are unsure how much support you need, call us before you order.

  5. Measurement E. Elbow height, where the armrests adjust

    Relax your shoulders, let your arms hang at your sides, and bend your elbow to about 90 degrees. Measure straight up from the seat surface to the bottom of your elbow.

    This gives you a comfortable armrest height on any chair with height-adjustable armrests.

Weight capacity

Always compare the rider's weight against the manufacturer's stated weight capacity. Never choose a wheelchair rated below the rider's actual weight.

If the rider is close to a chair's maximum, move up to a higher-capacity model.

BandCapacity
StandardUp to 300 lbs.
Heavy dutyAbove 300 lbs., up to 400 lbs.
BariatricAbove 400 lbs.

Make sure the wheelchair fits your home

Seat size is only half of it. Before you order, compare the wheelchair's overall dimensions against the places it has to go. Measure:

  • The narrowest doorway it has to pass through
  • Hallways and tight corners
  • The bathroom entrance
  • The bedroom entrance
  • Elevators, if you use one
  • Your vehicle's cargo space, if the chair travels

Check the manufacturer's listed overall width as well as the seat width. A wheelchair with a 20" seat measures considerably more than 20" from wheel to wheel.

For a power wheelchair, check the listed turning radius too, so you know it can turn where you need it to.

Need help choosing the right size?

Sizing varies between manufacturers and between models. If you are unsure which size to order, we are happy to help.

Send us your measurements along with the wheelchair you are considering, and a Hieline Medical specialist will compare them against that manufacturer's available seat sizes and specifications.

Call 1-855-HIELINE or email care@hieline.com with your measurements and the model you are considering, and we will tell you which seat size to order.

Important

This guide helps you select standard mobility equipment. It is not a clinical seating assessment. A rider with significant postural needs, pressure-management concerns, asymmetry, contractures or other complex seating requirements should be evaluated by a seating or rehabilitation professional.

Build & Buy
Color
Select one.What does this mean?

On this chair the color is the arm cover. The frame, the seat and the wheels are black whichever one you pick, and every color costs the same.

Arm covers are also sold on their own as a pair, so you can change the color later without changing the chair.

Seat
Select one.What does this mean?

This is two measurements and it is the choice worth taking time over.

Width is how wide the seat is across. Sit upright, have someone measure the widest part of your hips, then add about two inches so you are not pressed against the arms. Round up to the nearest size.

Depth is how far the seat runs from your back to its front edge. Measure from your back to the back of your knee, take off an inch or two, and aim for a gap of three or four fingers behind the knee.

All three sizes cost the same. The seat size also sets how wide the whole chair is, from 21.8" up to 25.6", which matters if you have a narrow doorway to get through.

If a therapist has measured you, their numbers win over anything here. If nobody has, use the measuring guide on this page.

Joystick mount
Select one.What does this mean?

This sets which armrest the controller sits on.

Put it on the hand you already use. For most people that is the hand they write with. Choose the other side if that hand is out of commission. Both sides cost the same and neither is an upgrade.

Joystick position
Select one.What does this mean?

This is the armrest the joystick sits on. Most people choose the side of their stronger hand. Both sides cost the same.

Legrests
Included.What does this mean?

This chair has one fixed footplate and no alternative, so there is nothing to choose here.

Accessories
Optional. Tap any add-on to include it in your order.What does this mean?

These are extras that fit onto the power wheelchair, and every one of them is optional. Adding them here means they arrive with it rather than as a separate order later.

Read each card before you add two of them. Some accessories mount in the same place, so only one of those can be fitted at a time.

Delivery
Included.What does this mean?

This section is how your order reaches you and how far into your home it comes.

Curbside is the free option. The power wheelchair ships from the manufacturer straight to your address. Allow about two to three days for the order to be processed and shipped, then about five more in transit depending on where you live. No carrier in this trade quotes an exact date, so treat both figures as estimates rather than promises. It arrives boxed at the curb, and getting it inside is yours to arrange.

This one comes in a single box and the setup is not hard. The box goes through a normal doorway and most people manage it on their own. The free option is a fair choice here.

Warranty
Included.What does this mean?

This section covers what the manufacturer warrants and for how long.

There is nothing to buy here. The full terms are in the Warranty tab further up this page.
