Click to zoomKi Mobility Dynaform Anterior Trunk Support
Ki Mobility's Dynaform anterior trunk support is a padded vest that crosses the front of the trunk and pulls from the rear at four points. Choose the standard or slim cut, the stretch or non-stretch fabric, and the size.
Ki Mobility's Dynaform anterior trunk support is a padded 4-point vest that holds the shoulders and chest back against the wheelchair, in a standard or slim cut and a stretch or non-stretch fabric.
What stands out
An anterior trunk support is for a user who cannot hold the trunk upright and falls forward, which a chest strap alone does not stop. The standard cut covers more of the chest. The slim cut narrows to an X, which leaves the arms freer and suits a smaller frame. The dynamic fabric stretches as the user moves and breathes, and the structure fabric holds firmer. Pick the size from Ki Mobility's chart by the height of the support, and add strap guides if the shoulder straps need to come over the top of the back. It is a positioning aid and not a restraint, so a seating professional should fit it.
Straight talk
Is it right for you?
A good fit if you
- fall forward in the wheelchair
- need the shoulders and chest held back
- need a support that tightens from behind
Look elsewhere if you
- only need a light chest strap (see the Dynaform chest support)
- need a restraint for transit
- want to try it and send it back, because it is not returnable
The Ki Mobility Dynaform Anterior Trunk Support is covered by Ki Mobility's own limited warranty. Call 1-855-HIELINE or email care@hieline.com and a specialist will send you the current terms in full.
This product cannot be returned
A chest or trunk support is worn against the body, so once it ships it cannot be returned. Check the size against the chart above before you order.
If something goes wrong
Call us first at 1-855-HIELINE. We file the claim with Ki Mobility for you and get the covered part sorted out rather than handing you a phone number.
