Several of the designers' more personal ideas and values went into the original Equa design, and they are preserved in the Equa 2 chair.
Both designers believed that everyone, regardless of size, shape or status, deserves a good, ergonomically supportive chair. They preferred simple designs, both in structure and operation.
They believed that the structure of a chair should be logical, and the materials appropriate. Finally, both enjoyed what they called "designing by analogies". Looking at familiar designs or things they appreciate, such as skis, toys, jukeboxes, bicycles and a wide variety of other objects, and determining those qualities that make them special. Then incorporating those qualities in their designs.
