Overview

A child-sized chair built like the adult one

A children's wheelchair at 30 lbs. with a carbon steel frame, flip-back padded desk arms, an adjustable back height and a dual axle that drops the seat to hemi height. Choose a 12" or 14" seat and swing-away footrests or elevating legrests. Holds 250 lbs.

Built for real life

What stands out

●

A frame that takes custom backs

The frame has no seat rail guides, which leaves the rails clear for an aftermarket back or a seating system to bolt on later as a child's positioning needs change.

●

Back height adjusts

The backrest sets between 16" and 18", so the top of the back can be kept below the shoulder blades of a child who self-propels.

●

Arms that flip back and lift out

The padded arms flip back for a sideways transfer and come off entirely. The receiver is angled so the arm drops back into place without lining it up by hand.

●

A release lever that works either way

The front mounted lever that unlocks the flip-up arm can be set to flip up or down, depending on which direction the child can reach.

●

Dual axle to hemi height

Move the rear wheels to the lower position and the seat drops to 15.5", low enough for a child to reach the floor and walk the chair with their feet.

●

30 lbs. with maintenance-free wheels

Composite mag wheels with polyurethane tires never need inflating and the bearings are sealed front and rear.

The Hieline Take

Most of what a parent is shopping for at this size is a chair that fits now and can be changed as the child grows, and this one is built for that. The back height moves between 16" and 18", the dual axle moves the seat between 15.5" and 17.5", and the frame has no seat rail guides, which leaves the rails free for a custom back or a seating system to be added later. The seat depth is fixed at 12" in both widths, so growth room comes from width and from the back rather than from the seat, and a child who has outgrown 14" moves to an adult chair. At 30 lbs. in steel it is heavier than an aluminium adult folder, and that weight is the price of a frame that will take hardware bolted to it. Composite mag wheels with polyurethane tires mean no punctures and no pump. The arms flip back and come off for a sideways transfer, and the lever that releases them can be set to work up or down, which matters when the child is the one operating it.

Straight talk

Is it right for you?

A good fit if you

need a 12" or 14" seat for a child who is too small for an adult chair
want the child to self-propel, because the back height and seat height both adjust
weigh up to 250 lbs.
want to add a custom back or seating system later

Look elsewhere if you

need a seat wider than 14"
need the back to recline, because this one does not
want a chair under 25 lbs.
need a colour other than black

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

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.

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.

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.
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.
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.
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.
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.

Band	Capacity
Standard	Up to 300 lbs.
Heavy duty	Above 300 lbs., up to 400 lbs.
Bariatric	Above 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.

Your measurements

Type your numbers straight into the boxes below, or print this page and write them in by hand. When you are done, copy them and email them to us, or call and read them out.

A. Hip width inches

B. Seat depth, upper leg length inches

C. Lower leg length inches

D. Back height inches

E. Elbow height inches

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.
