Meaning 2: Interactions Between the 3 Levels of Meaning

Representational 
- identify what role it plays in the whole 
- describe what kind of impact it has for the user/viewer 
- how it relates to the other two levels 
This is the Panton plastic chair designed by Verner Panton and introduced to the world in 1968. It is a representative of a chair due to it's ergonomic form. People understand it's a chair by the curves and structure hinting where to sit and where to put one's legs. The impact of this chair is its chair form of elevating the sitting surface and the downward curve suggests where one would nest their bottoms. We can say the form of a furniture for one to rest in derives from function and ergonomics with the hollow shell on the bottom as weight support structure. The form (based on function/representation of a chair) also connects to an abstract form of a flower, a flowing brush stroke, water flow, or even symbolize the letter "S" or number  "5".

Abstract

In terms of the idea for creating this chair, Panton wanted to use a single piece of plastic and convey the messages of "Sleek, sexy and a technical first". The abstract form is created by the goal of fiberglass casting one piece of the chair. When multiple Panton chairs are arranged in different angles the composition portrays sexy strokes, sleek paint flow, or even swans in an abstract way. The abstractness of the chair when it's photographed artistically doesn't lose its meaning that "it's a chair" and symbol of "5" or a "S" or even a "V".

Symbolic
In Dondis's book, the author identify a symbol must "not only be seen and recognized but also remembered and even reproduced". The Panton chair highly associates with the symbols "S" and "5".
