Watch it in action

S-Ergo 305 introduction

Built for real life

What stands out

●

Three seat heights

Karman sets the seat at 18", 19" or 20" to suit your leg length, and the rear axle adjusts to match.

●

Arm pads that raise

The arm pads adjust from 9" to 11" and the armrests flip back for side transfers.

●

Quick release wheels

The 24" rear wheels come off with one button, so the folded chair gets smaller and lighter to lift.

●

An S-shaped seat

Karman shapes the seat frame in an S so it follows the curve of your thighs and hips, which spreads your weight and holds you in place.

●

It folds flat

The seat folds and the backrest folds down, so the chair packs to 12" wide.

●

Flat-free wheels

The rear wheels and the front casters are solid polyurethane, so there are no tires to pump up.

The Hieline Take

The S-Ergo 305 is the S-Ergo you set up around yourself. The seat height comes at 18", 19" or 20", so a shorter rider can reach the floor with their feet and a taller one is not sitting with their knees high. The arm pads raise and the armrests flip back, and the quick release wheels come standard. The cost is 4 lbs. over the S-Ergo 115 and $161 more. If you are of average height, transfer standing and rarely load the chair into a car, the 115 does the job. If any of those three is not you, the 305 is worth the extra.

Straight talk

Is it right for you?

A good fit if you

want the seat height set to your legs
transfer sideways and need the armrests out of the way
load the chair into a car often and want the wheels off in one move
weigh up to 250 lbs. and fit a 16" or 18" seat

Look elsewhere if you

want to save every pound, since this one is 29 lbs. against the S-Ergo 115's 25 lbs.
need a 20" seat
weigh more than 250 lbs., which is the chair's limit
need a seat deeper than 17"

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

Rider weight lbs.

Narrowest doorway 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.
