Introducing the Catalyst 4E, raising the bar in both performance and quality.
Catalyst...the ride you expect, the brand you depend on.
Feature Tour
There is a Catalyst Difference
Catalyst 4E takes advantage of all of the "Catalyst Difference" design features to allow you to fit, adjust and ride with confidence. A defining characteristic of each chair is its axle plate which we will highlight below.
Lightest in Class
Utilizing high-quality materials and innovative design Catalyst 4E is the lightest folding frame in the category, with an unprecedented 13.3 lbs transport weight! The lighter weight makes it easier for caregivers and clients without sacrificing quality or durability.
Best-In-Class Performance
Staying true to the Catalyst design and quality standards, Catalyst 4E uses the Dual-Cross Brace design that brings best-in-class rigidity and performance to the category. Integrated within the Dual-Cross Brace is the patented, exclusive Catalyst Power X-Hinge that makes folding and unfolding so easy! The combination results in a better, easier experience for clients and caregivers.
Quick and Infinite Adjustability
Make setup easier and quicker than ever with the one-tool, anti-rotation leg length adjustment! Integrated into the reliable and familiar Catalyst hanger, the new adjustment design comes with the exclusive lifetime hanger warranty only available from Ki Mobility.
Do more with less!
Reach new heights with fewer part changes! The single-frame design offers 5.5" of front seat height range by caster size, which is 1.5" more than the competitive designs. In combination with a new ultra-low caster housing, Catalyst 4E provides maximum adjustability over competitive designs. (12.5" - 21" | 31.8 cm - 53.3 cm)
