The challenge was to invent a heated chair that didn’t infringe on an existing patent. 4J International widened the frame and seat to accommodate bigger bodies, re-engineered the heating coils, and made the chair compatible with Snap-on’s universal battery. They also added a compartment that stores five cans of the client’s favorite beverage to the armrest, taking leisure to the next level.
