What are the ergonomic considerations for designing polyethylene bench seats?
Designing polyethylene bench seats with ergonomic principles ensures comfort, durability, and user satisfaction. Key considerations include seat height (typically 17-19 inches for optimal leg support), depth (around 18 inches to prevent strain), and backrest angle (slightly reclined at 100-110 degrees for lumbar support). Contoured seating surfaces and rounded edges reduce pressure points, while high-density polyethylene (HDPE) offers weather resistance and easy maintenance. For public spaces, sloped designs (1-2 degrees) prevent water pooling. Armrests and textured surfaces enhance accessibility and safety. Balancing these factors creates functional, long-lasting seating solutions for parks, transit areas, and commercial settings.
