CONVAID USER’S GUIDE
Fitting
The fitting of the cushion should be done by an experienced clinician. When fitted correctly, the
cushion will help provide stable support and promote good posture . Consult the clinician for questions
regarding individual needs .
While in the seated position, select the cushion size to match the user’s hip width . The cushion length
should equal the distance from the back of the buttocks to the back of the knees (plus 1 inch) .
1 . Place the cushion to the back of the wheelchair with the material identification tags towards
the rear . Position the hips to the back of the seat . The ischials (seat bones) should be
centered on the seat well of the cushion .
2 . Align the Velcro strips with those on the wheelchair seat . Secure the cushion in place .
3 . Adjust the wheelchair footrest height so that the user’s legs rest firmly but comfortably on the
cushion . Proper footrest adjustment will enhance sitting comfort and help lower peak sitting
pressures .
CAUTION
Installing a cushion on a wheelchair may affect the center of gravity and cause the wheelchair to
become unstable, potentially resulting in injury . Prior to use, assess the stability of the wheelchair by
sitting in it with the cushion attached .
Ensure the cushion’s Velcro is in good condition and is aligned properly with the Velcro on the
wheelchair seat. Make sure the cushion is firmly attached. An improperly attached cushion may cause
sliding, potentially resulting in injury .
Changes in the user’s condition or growth, or changes in wheelchair equipment or accessories
may require reassessment by a clinician to ensure proper cushion fit and suitability. Skin should be
constantly checked by the user’s caregiver for any signs of reddened areas or skin sensitivity . These
areas should be brought to the attention of a clinician . The clinician should also assist the family with
assessing the cushion for any possible areas that have bottomed out .
