CONVAID USER’S GUIDE
Fitting
Caution
The fitting of the cushion should be done by a clinician. When fitted correctly, the cushion will help
provide stable support and promote good posture. Consult your clinician for questions regarding
individual needs.
Select the cushion size to match the seat width and depth of the chair. Measure the distance between
the back of the buttocks and the back of the knees. Subtract 25mm - 51 mm to allow for adequate
clearance between the seat and the back of the knees.
1. Apply wheel locks. Never leave occupied chair unattended.
2.
With the material identification tag towards the rear of the chair, place the cushion onto the seat
upholstery. Line up the Velcro
®
straps to secure the cushion in place. Front end of cushion should
line up with the front edge of the seat upholstery. Position the hips of the occupant to the back
of the seat. The ischials (seat bones) should be centered on the seat well of the cushion. Use
positioning belt to buckle occupant into the chair.
3.
Adjust the wheelchair footrest height so that the user’s leg rest firmly but comfortably on the
cushion. Proper footrest adjustment will enhance sitting comfort and help lower peak sitting
pressures. If applicable, readjust armrest height and lateral trunk supports.
The height and weight of the occupant, in conjunction with a seat cushion, 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, weight 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 your clinician. The clinician should also assist you with
assessing the cushion for any possible areas that have bottomed out.
