Etac Cross 5 and Cross 6, can be set up for both a taller or a shorter users with different body shapes.
The majority of users will use the standard back support. Using the standard back support, the 3A-back support can be adjusted in height from 32 cm to 45 cm. And with the high back support you can get as high as 51 cm.
Once the desired back height is adjusted and set, the fine tuning of the strap back can be done, and any accessories to support and shape up the posture can be added.
A user with a tall upper body may also need a longer seat depth. By angling the seat to back angle posteriorly, and the the back rail forward, the seat depth is extended (1). Add a seat extender (2) and make sure the back cover is placed to create rear space (3).
Choose the high back support with seven back straps (3).
If the user is leaning heavily towards the back, a cross brace (4) is recommended.
Firmer side stability can be created by using the plush wedges (5).
