Click to zoomKarman S-Ergo 115 Ultra Lightweight Wheelchair
An ultra lightweight folding wheelchair with Karman's S-shaped ergonomic seat. It weighs 25 lbs. without footrests, carries 250 lbs. and comes with a 16", 18" or 20" seat in red, silver or white.
A folding manual wheelchair light enough to lift into a car, with an S-shaped seat that spreads your weight and holds your hips in place.
What stands out
The S-Ergo 115 is Karman's core ergonomic folding chair, and its selling point is the seat. A flat sling lets you sink and slide forward over a long day, while the S-shaped frame holds your hips and spreads your weight, and at 25 lbs. without footrests you can still lift it into a car yourself. The standard build, with flat-free wheels and fixed axles, covers everyday use. Quick release axles are worth the extra if you load the chair often, because the rear wheels come off and the folded chair gets lighter. The armrests are fixed, so if you slide out sideways to transfer, this is the wrong chair. Measure your hips before you pick a width, because Karman builds this chair to your order.
Straight talk
Is it right for you?
A good fit if you
- wheel yourself and want a chair light enough to lift into a car
- weigh up to 250 lbs. and fit a 16", 18" or 20" seat
- sit for long stretches and want a seat that holds your hips in place
- want wheels that never go flat
Look elsewhere if you
- weigh more than 250 lbs., which is the chair's limit
- need a seat deeper than 17", which is the only depth Karman builds
- need armrests that flip back for side transfers, because these are fixed
- will only ever be pushed by someone else, where a transport chair is lighter still
The Karman S-Ergo 115 Ultra Lightweight Wheelchair is covered by Karman Healthcare's own limited warranty. The coverage we have on record is below.
The owner's manual is the full warranty
The owner's manual for this product has its own warranty section, and that section is the complete statement of what Karman Healthcare covers, for how long, and what falls outside the coverage. Read it before you file a claim. If anything on this page differs from the manual, go by the manual.
Owner's manualThis product cannot be returned
Karman Healthcare builds each S-Ergo 115 to the choices you make on this page, and Karman's return policy does not accept configured or special-order wheelchairs, so this chair cannot be returned once the order is placed. Check the seat width, frame color, axles, wheels and legrests before you add it to your cart. The warranty is unaffected, so a fault is still a fault and we handle it.
If something goes wrong
Call us first at 1-855-HIELINE. We file the claim with Karman Healthcare for you and get the covered part sorted out rather than handing you a phone number.
