“Over the past several months I have become familiar with the products and services of Back Quality Ergonomics. I also purchased one of their stools for use in a clinical setting. What caught my attention initially was the quality craftsmanship. In conversations with the principals in the company and the sales team I was delighted by their ability to succinctly describe the ergonomic benefits of their products and the many features that fit multiple positions and body heights.”
