The functional chair is an ergonomically designed chair designed to provide comfort and support, allowing the user to maintain a good body posture when sitting for a long time. It brings together ergonomic principles and modern technology to provide users with an excellent sitting experience.

Ergonomics is the study of the relationship between the human body and the working environment, with the aim of increasing productivity and protecting the health of workers. The ergonomic design takes into account the anatomy and mechanics of the human body to ensure that the human body maintains a natural posture and reduces stress and fatigue during work and rest.

The function chair provides several important features and functions through ergonomic design, as follows:

First, the functional chair has adjustable seat height and angle. This allows users to adjust the seat height and angle according to their height and preferences to ensure proper spine alignment and a comfortable sitting posture. The seat height adjustment range is usually 38-49cm to accommodate users of different heights.

Second, the back support of the functional chair may provide adequate lumbar support. It usually has an adjustable back support area, allowing users to adjust the height and angle of the back support according to their needs to provide **lumbar support. This helps reduce pressure in the lumbar region, preventing and relieving pain in the lumbar spine.

Third, the seat and backrest of a functional chair usually have appropriate padding to provide a comfortable sitting experience. Pads are usually made of highly elastic and breathable materials, such as memory foam and mesh, to ensure comfort and breathability for long-term sitting. The shape and curve of the seat and backrest have also been carefully designed to provide support and pressure dispersion.

Fourth, functional chairs usually have adjustable armrests. The height and angle of the armrest can be adjusted according to the needs of the user to provide proper support and relaxation for the arm. This helps reduce pressure on the shoulders and arms, preventing and relieving pain in the shoulders and arms.

Fifth, functional chairs usually have an adjustable seat recline function. Users can adjust the tilt angle of the seat according to their needs to provide appropriate support and comfort. This enables the user to adjust the tilt angle of the seat to reduce the stress and fatigue of the body under different working and rest conditions.

In summary, the functional chair has an ergonomic design that provides users with an excellent sitting experience through adjustable seat height and angle, backrest support, padding, armrests and seat tilt functions. It maintains normal body alignment and posture, reduces stress and fatigue, and prevents and alleviates related health problems. As an important tool to improve work efficiency and quality of life, functional chairs are widely used in offices, homes and other places.
