A large upper body, a large trunk, sometimes requires a longer seat depth to accommodative the additional mass of the larger glutamate shelf.

Check that the seat is equipped with a seat extender (1), adjust the seat to back angle posteriorly. Loosen all Velcro straps and place the cover with plenty of room at rear so the seat cushion can be placed as far back as possible. This allows more space for the buttocks. Adjust the lumbar angle forward and aim for Trunk Extension (2). Make sure the user is still leaning towards the back support. Add a Cross Brace (3) if it is not already included.

If needed, attach Width Extensions (4) and Plush Wedges (5) to broaden the upper part of the back support.

A correctly fitted wheelchair should not make the user feel restricted or limited in movement, it is important to create the correct space and comfort for the larger body to increase sitting tolerance.

2. Back Support Adjustment

Make sure there is sufficient room for the buttocks, keep the lower tension adjustable back strap slackened and start by tightening the back straps at the level of PSIS.

With the seat to back angle posteriorly adjusted, the back support will be slightly lower.

For a tall person, it´s often necessary to set a higher back, for this choose the Back extension 3A accessory.

3. Rear cross brace

The addition of the rear cross brace will secure the back support in a more rigid setting when a heavier or larger user is leaning into the back straps.

The rear cross bracer can easily be folded with a snap lock.

2. Width Extentions

The width extentions broaden the back by supporting the plush wedges further outwards. This is the wide model. There is also a side stop with half the width. They are adjustable in height, depth and angle.

To mount, just slide them into the back rails and fasten the screws.

5. Back wedge, Plush

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.

Pressure distributor

The pressure distributors are a useful accessory that can be added to create a feeling of a wider back, and they will also distribute pressure away from the thoracic spine when the larger user is heavily resting on the back profile tubes.
