CONVAID USER’S GUIDE
Fitting Guide
Convaid’s lightweight, folding chairs are designed to be more than just a convenient chair. Order the
correct size chair by rst determining the user’s height, weight and seating measurements.
Properly-tted, Convaid chairs will provide years of comfortable use.
Correct seating and positioning encourages good posture, which in turn aids circulation, breathing and
digestion. Please take the time to properly adjust the chair to t the user. If the user is not correctly
positioned, check the accessories section of this manual to see if one or more of our accessories
would help to facilitate posture or consult a physical therapist. Improper seating can cause problems.
Please consult a physical therapist or doctor for additional guidance.
Seat back height varies according to chair type and seat width. Headrest
extensions are available when extra height is needed to support the head.
To determine the seat back height, measure from the seat to the top of the
shoulder or the upper part of the head. Fig. 14
Proper seat width enables the user to sit comfortably and prevents problems
from developing. While user is seated on a at surface, measure from hip to
hip. Fig. 15
The user should have enough room to prevent hips and thighs from rubbing
against the frame. However, the chair should not be too wide or the user will
slide around and posture could be affected.
The seat width measurement for the Metro is taken from the actual seat
width.
