This document outlines the process for designing a cardboard seat that follows certain constraints. It begins with exploring existing cardboard chair designs and identifying the problem of wanting to create a simple, reusable seat from waste materials. Next, it discusses brainstorming ideas and considering built types like folding and interlocking designs. Finally, it specifies the materials needed, which are just cardboard and basic cutting tools, and provides examples of specific cardboard furniture inspirations. The overall goal is to design an efficiently assembled, low-cost cardboard seat that addresses environmental and waste issues.
