How to design foldable polypropylene bar stools without compromising strength?

Designing foldable polypropylene bar stools that remain strong and durable requires careful consideration of materials, structure, and engineering. Polypropylene is a lightweight yet resilient plastic, making it ideal for foldable furniture. To ensure strength, reinforce critical joints with metal hinges or thickened polypropylene sections. Opt for a ribbed or textured surface to enhance rigidity while keeping the stool lightweight. The folding mechanism should be simple yet robust, avoiding weak points that could fail under weight. Balance portability with stability by testing load capacity during prototyping. By prioritizing structural integrity in key areas, you can create foldable stools that are both space-saving and sturdy.
