Basic Seat Dimensions
The seat height is generally set at around 45 cm. This ensures that the user's feet rest naturally on the ground, with their thighs parallel to the ground, preventing fatigue from prolonged sitting.
The seat width ranges from 40-50 cm, which meets the seating needs of most adults and ensures adequate support for the buttocks.
The standard seat depth is 40-45 cm. This moderate depth effectively supports the legs while allowing for adequate room to move around.
Overall Structural Dimensions
The total height of the dining chair, including the backrest, is controlled between 80-90 cm. This height range forms a reasonable proportion with a standard dining table.
The backrest height is typically between 35-45 cm, providing necessary support for the lumbar spine and maintaining correct posture.
Ergonomic Design Considerations
The dimensional parameters are based on large-scale statistical analysis of Asian adult anatomy, meeting the needs of 90% of the population.
The proportions of each part strictly follow the body pressure distribution patterns under sitting conditions, especially the matching degree of the seat curvature with the spinal curve.
Material selection should consider the balance between cushion resilience and support; high-density foam is generally an ideal choice.
When making a specific purchase, it is recommended to consider personalized factors such as the user's height and the usage scenario (e.g., formal restaurant or casual area). Customization services are also available for those with special needs to achieve the best user experience.
