Bring your Matrix KI stacking bumper chairs back to life with this precision-engineered replacement stacking/ganging connector.
If you own KI Matrix chairs, you already know these small plastic connectors eventually crack or break — and KI no longer manufactures replacements for this model.
We 3D-print these custom connectors in the USA using durable, impact-resistant engineering-grade filament designed to outlast the originals. Each piece is modeled from the OEM shape and dimensions to ensure proper fit, spacing, and stacking stability.
This replacement fits Matrix KI chairs listed under U.S. Design Patent D.246.813, commonly used in churches, schools, auditoriums, conference rooms, and event spaces.
