How to design PVC outdoor bar stools for ergonomic lumbar support?

Designing PVC outdoor bar stools with ergonomic lumbar support requires careful consideration of materials, shape, and functionality. Start by selecting high-quality, weather-resistant PVC to ensure durability in outdoor conditions. The stool's backrest should curve slightly inward to support the natural arch of the spine, promoting proper posture. Adjustable height options can accommodate different users, while a slight recline angle (around 100-110 degrees) reduces lower back strain. Adding cushioned seating or contoured designs enhances comfort for prolonged use. For optimal ergonomics, ensure the stool's depth allows users to sit with their feet flat on the ground or a footrest. These design elements combine style and functionality, making PVC bar stools ideal for outdoor lounging.
