What are the ergonomic considerations for outdoor armchair design?

Designing an outdoor armchair with ergonomic principles ensures comfort, support, and durability for extended use. Key considerations include:

1. Seat Height and Depth: The seat should allow feet to rest flat on the ground while thighs are parallel to the ground, preventing strain.

2. Backrest Angle: A slight recline (100-110 degrees) supports the spine and reduces lower back pressure.

3. Armrest Height: Positioned to support elbows without raising shoulders, enhancing relaxation.

4. Material Durability: Weather-resistant materials like teak or aluminum ensure longevity without sacrificing comfort.

5. Cushioning and Breathability: High-density foam with breathable fabrics prevents overheating and maintains comfort.

By prioritizing these factors, outdoor armchairs can blend ergonomic excellence with aesthetic appeal for ultimate relaxation.
