Seat depth is an important function of every chair. It promotes proper seating position and can help with pressure reduction. So many manufacturers use seat upholstery to measure the seat depth, leaving excess front frame protrusion. Ki Mobility matches the frame depth to our seat depth, on every chair. This results in a lighter chair, improved turning radius, easier transportation, storage, and a better result for the client.
The Dual Interlocking Cross Brace design creates a frame that locks together to minimize the unwanted movement, or "front to back" racking while redistributing loads onto components that can better manage forces. What this means to you is that no matter how much you use your Catalyst, the frame will remain as solid as it was the day you got it.
In typical above-the-rails designs all of the forces from the ground up, into the chair, and from the user down, through the chair, are transferred into the cross braces. In order to effectively deal with these loads, other manufacturers design heavy cross-braces. The Catalyst's unique "between-the-rails" design transfers these loads from the cross brace to the vertical side frames. The geometry of the side frames allows them to support far greater loads.
Other wheelchairs rely on the tension of the seat sling to solidify their frame when opened. However after a few months the upholstery experiences a natural stretching and your chair is "loosey goosey". The Power X-hinge eliminates the need for the seat sling to be a structural part of your frame. A Catalyst is solid even without upholstery. This ensures a more rigid and responsive ride.
