Click to zoomKi Mobility Axiom SP Fluid Cushion
Ki Mobility's Axiom SP Fluid is a skin protection and positioning wheelchair cushion. A dual density polyurethane foam base holds the hips and thighs, and a Hydrolite fluid pad sits right under the outer cover in the well to envelop the sitting bones and tailbone. Choose the width and depth of your seat and the standard or incontinence resistant outer cover.
Ki Mobility's Axiom SP Fluid is a skin protection and positioning cushion with a Hydrolite fluid pad in the well, 14" to 22" wide, rated to 350 lbs.
What stands out
The Axiom SP Fluid is for a user who needs skin protection and positioning and needs more envelopment, such as someone who sits all day, shifts in the seat or has had a pressure injury. Hydrolite holds its shape at rest and flows under load, which helps reduce shear, and it is light for a fluid cushion. Check the fluid pad sits flat on the inner cover after cleaning, as the manual shows. Measure the seat of the wheelchair, not the person, before you order.
Straight talk
Is it right for you?
A good fit if you
- need skin protection and positioning from one cushion
- need more envelopment, or shift in the seat
- have had or are at risk of a pressure injury
Look elsewhere if you
- want a cushion with nothing to check after cleaning (see the SP Visco)
- want a thin, light foam pad
- want to try it and send it back, because a cushion is not returnable
The Ki Mobility Axiom SP Fluid Cushion is covered by Ki Mobility'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 Ki Mobility 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
A cushion is a support surface that sits against the body, so once it ships it cannot be returned. Measure the seat of your wheelchair before you order and use the size steps above. The warranty is unaffected, so a defect is still covered.
If something goes wrong
Call us first at 1-855-HIELINE. We file the claim with Ki Mobility for you and get the covered part sorted out rather than handing you a phone number.
