What are the ergonomic considerations when designing rattan seating sculptures for parks?

When designing rattan seating sculptures for parks, several ergonomic factors must be prioritized to ensure comfort, durability, and aesthetic harmony. First, the seating height and depth should accommodate diverse body types, typically ranging from 16-18 inches in height and 18-20 inches in depth for optimal support. Curved backrests (around 100-110 degrees) promote natural spinal alignment, while armrests reduce strain.

The flexibility of rattan allows for organic, body-conforming shapes, but structural integrity must be maintained with weather-resistant treatments. Slatted designs enhance breathability and prevent moisture buildup. Accessibility considerations include leaving clear ground space (30x48 inches) for wheelchair users and avoiding sharp edges.

Sustainable rattan sourcing and non-toxic finishes align with eco-friendly park values. The sculptures should blend ergonomics with artistic expression, creating inviting spaces that encourage prolonged relaxation while withstanding heavy public use. Maintenance planning for woven surfaces ensures long-term functionality.
