Ergonomic Requirements:
- The seat width should correspond to the user's hip width, providing a comfortable seating area.
- The seat height should be moderate and adjustable to suit the user's height.
- The angles of the seat and backrest should conform to the user's natural posture as much as possible, providing support for the user's neck, waist, and legs to prevent fatigue and injury.
- The seat cushion should have moderate elasticity, providing stable support and reducing user vibration and bumps.
Material Selection:
- The seat frame should be made of high-strength, lightweight, corrosion-resistant, and easy-to-clean alloy materials.
- The seat cushion and backrest should preferably be made of breathable, waterproof, and stain-resistant materials to prevent user discomfort due to sweat during experiments.
- The seat casters and footrests should be made of non-slip, wear-resistant, and quiet materials to reduce noise and friction, extending the seat's lifespan.
