Our internationally peer-reviewed and accepted Chair Assessment System (CAS) is a novel chair asset management system in the ergonomics marketplace. Designed to help you inventory and assess the mechanics of your chairs and determine whether to KEEP, REPAIR, or REPLACE them.

"As a chair reseller, the CAS is extremely valuable due to its utility in tracking client chair assets for ongoing use. The Chair Assessment System (CAS) has been highly effective in giving our business a market edge by enabling the Australian Federal and State Governments to obtain up-to-date chair status reports. It has put our company in a position to secure the sale of replacement chairs now and in the immediate future.

The CAS is a vital part of our Chair Health Check program, enabling us to track the sustainability and removal of unwanted chairs for our clients, followed by the purchase of replacement chairs. Other chair resellers would financially benefit from the CAS."

I can definitely see the value for organizations that manage their chair inventories or are trying to get more strategic about chair fit, lifecycle decisions, and budget planning. 

The QR code tracking, built-in evaluation forms, and reporting dashboard stood out as practical, scalable tools for facilities, EHS, and ergonomics teams.  

For clients with high chair volumes or remote workforces, having an organized, data-driven system like this could really help optimize spend and improve user support.”
