Seat width (SB)
SBs range from 280 - 500 mm.
Once the SB is specified, it is very difficult to change it: the cross
struts, backrest cover (on standard backs) and, on some configura-
tions, the footrests must be replaced.
Seat depth (ST)
STs range from 320 - 500 mm.
To reduce the ST, the cross struts must be shortened and a new ap-
propriately sized seat cover fitted. At an ST ≥ 400 mm, the frame can
be shortened.
To enlarge the ST, new cross struts, a new appropriately sized seat
cover and, depending on the ST, a new frame must be installed.
