Determine your wheel and caster selection based upon your desired seat height. Once determined, be
sure to check Caster and Footrest Compatibility charts before ordering or making any physical changes to
the chair. Also, be aware that a specific rear seat height may be accomplished with more than one type of
axle plate. See axle plate positioning matrix to determine if your current axle plate may be utilized for your
desired rear seat height.

Seat Height - Casters
Seat Height - Caster Compatibility charts are utilized to prevent interference between the caster and side
frame or caster and hanger/footrest. Higher degree hangers and larger casters are more likely to create
interference. Use the charts below to determine if your wheel, caster, caster stem and seat height
configuration will work with your desired hanger angle selection.
