Cross 6_hero banner_2250x600.jpg

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.

With asymmetry each situation will need carefully assessing, there are various options for accessories to help support the individual's postural needs.

(1) If there is pelvic obliquity that is contributing to asymmetry the cushion set up is crucial and a cell foam wedge under cushion may help. (2) The lumbar angle can be set asymmetrically if needed. (3) Side cushions can be used to help keep the trunk up right, (4) and the long and short plush wedges can be used for creating contour and support under the back cover. (5) Cell foam wedges cam be used to help create contouring and to ill the gaps to provide greater contact with the back cushion.

1. Cell Foam Wedges, Large

A cell foam wedge is an easy way to adapt a non adjustable seat cushion. Placed inside the cover on the cushion underside it will not affect the cushion`s density. Attach the wedge with the included self adhesive Velcro.

2. Back support adjustment

To achieve optimal back support you can individually adjust the left and right side angle.

If the left and right seat to back angle are diverse adjusted, test to counteract trunk rotation and/or lateral trunk flexion by angling one upper back rail more forward.

3. Side cushion

Firm cushions with padding towards the user. The cover has a zipper to enable individual contouring with added foam.

They are 29 cm (11½") high and can be rotated for slimmer upper support.

4. Plush wedges

There are two lengths to choose between, 15 cm (6") and 30 cm (12"). Usually the short model is sufficient.

Attach the wedges with the Velcro facing forward, towards the back cover. If the user feels the edge of the back cover, chose one size wider that will fully cover the widened wedges.

5. Cell Foam Wedges

These cell foam wedges are slightly wider but lower than the plush wedges.

Placed below the plush wedges they are an excellent complement providing support in the waist area. They attach to the back cover with included self adhesive Velcro.

Pressure distributor

The pressure distributors could be used instead of the short plush wedge to spread the load or to create a support behind the higher shoulder (like in the image below).

Example of accessory placement

Example of accessories placed on the back support. Here with the side cushion, the large cell foam wedge and the soft plush wedges for extra support and comfort to shape up the asymmetric body shape.

When working with asymmetry, often the shoulders will not be level, it is important to provide support for the higher shoulder also. This placement of accessories shows this.
