Every Employer Needs a Qualified Chair Expert

Chairs are a primary risk in the modern office contributing to musculoskeletal disorders.

Every Employer Needs a Qualified Chair Expert

Seated work injuries cost employers an average of $40,000 per workers' compensation claim according to the Workers' Compensation Insurance Rating Bureau. Those claims are likely associated with poorly adjusted, old, or failing office chairs.

Your ergonomic chairs are the most important asset in the workplace, aside from the computer contributing to employee productivity. Yet, they are the most misunderstood, undervalued, and poorly managed assets in the workplace. Employers fail to recognize the chair life cycle of keep, repair, replace, and fit.

Becoming a Chair Assessment Specialist means you will:

  • Develop a chair asset management process including chair standards
  • Monitor and measure chair sustainability
  • Assist individuals with proper chair fit and use.
  • Reduce organizational risk
  • Minimize worker’s comp claims for seated workers,
  • Contribute to a comfortable, healthy, and productive workplace.
