How to Repair a Damaged Steelcase Cachet Chair Armrest

Introduction

The Steelcase Cachet swivel chair is a desk chair model that has hollow plastic armrests. When extreme force is applied to these armrests, they can fracture, or even cave in on themselves. If your chair’s armrest has been damaged to this extent, follow the basic instructions in this guide to restore the armrest’s smooth surface and have your armrest safe for use again.

When following this guide, exercise caution while working with broken edges to avoid injury. In addition, be sure to wear protective latex gloves while working with plastic repair putty, as this substance can be toxic. The putty used in this guide does not match the chair to provide a clearer view of the repair process. However, you can purchase putty that matches the chair.
