In the late 1980s, a police officer who suffered from back problems, designed and produced rough sketches of a new, innovative vehicle seat that helped relieve back problems. From there, the police officer, in combination with renowned Wisconsin industrial designer Brooks Stevens Design Firm, took the project and finessed the design.

One year later, Concept Seating was born. In 1995, Concept Seating expanded their line with the development of 24/7 Intensive Use chairs. The company now serves industries that need chairs for dispatch and call centers, heavy duty usage, big and tall seating, monitoring stations, and other occupations requiring long sedentary periods. Concept Seating remains committed to providing sophisticated seating with unparalleled durability while addressing the need that sparked the original idea: create seating that increases employee morale and productivity while decreasing time away from the job.
