What ergonomic factors should be considered when choosing a dining chair?

When choosing a dining chair, the following ergonomic factors need to be considered comprehensively to ensure the comfort and health of the user:

1. Chair height
Seat height: The seat height should match the height of the dining table. Usually, the distance from the seat surface to the ground is about 45 cm, which is suitable for most people.
Space left: Generally, 25-30 cm of space should be left from the seat surface to the bottom of the table to ensure the comfort of leg movement.

2. Seat depth and width
Depth: The seat should support the user's thighs. The depth is generally 40-50 cm, which can avoid being too deep (affecting the comfort of small users) or too shallow (affecting the support of large users).
Width: The seat width should be wide enough to accommodate users of different body shapes, generally not less than 45 cm.

3. Backrest design
Angle: The ideal backrest tilt angle is 100-110 degrees, which can balance between upright and slightly relaxed postures.
Support: The backrest should conform to the natural curve of the human spine, especially the support of the lower back is essential.

4. Armrest height (if there is an armrest)
Armrest height: usually 20-25 cm from the seat surface, so that the arms can hang naturally, and avoid being too high or too low to cause shoulder fatigue.
Width and comfort: The armrest design should be easy to support but not hinder dining movements.

5. Seat cushion and material
Softness and support: The seat cushion should be moderately soft to relieve the pressure on the buttocks from long-term sitting, but it should not be too soft to avoid lack of support.
Breathability and durability: The fabric needs to consider breathability to avoid stuffiness when sitting for a long time, and the material should be easy to clean and durable.

6. Stability and structure
The seat must be stable, avoid shaking or imbalance, and the leg design and overall structure should be able to withstand regular dynamic use requirements.

7. Weight and mobility
The dining chair should be easy to move, but not too light and unstable. The weight is usually between 2.5-5 kg.

How to judge whether a dining chair is worth buying?

To judge whether a dining chair is worth buying, you can evaluate it from the following key factors:

1. Material selection
Main material: Check the main material of the dining chair, such as wood, metal, plastic or composite material. High-quality hardwood (such as oak and walnut) is more durable, metal is suitable for modern style and more stable, and plastic is light but may not last long.
Coating and surface treatment: Is the wood waterproof and anti-corrosion treated? Is the metal part rust-proof? Check the surface smoothness to ensure that there are no obvious scratches or roughness.

2. Structural stability
Connection process: Check the connection between the chair legs and the seat and backrest. Chairs with mortise and tenon structures or bolts are usually more secure. Avoid choosing dining chairs that are only fixed by glue.
Shake test: Gently shake the chair to observe whether there is looseness or shaking. A good quality chair should be as stable as a rock.

3. Comfort and ergonomics
Cushion and support: Try sitting on the chair to feel whether the cushion is soft enough and whether the backrest fits the natural curve of the lumbar spine.
Size ratio: Make sure the height and depth of the seat match the height of the dining table and your height.

4. Craftsmanship details
Workmanship: Observe whether the surface of the chair is evenly painted, whether the seams are tight, and whether the screws and nails are exposed. High-quality dining chairs usually pay attention to these details.
Welding and splicing: Metal chairs should check whether the welding points are firm and crack-free; wooden chairs should have no obvious gaps or warping at the seams.

5. Durability and load-bearing capacity
Maximum load-bearing capacity: Check the load-bearing capacity in the product description. Generally, the load-bearing capacity of high-quality dining chairs should not be less than 120 kg.
Durability test: If conditions permit, you can ask whether it has been tested for durability, such as simulating wear after long-term use.

6. User experience and safety
Anti-slip design: Whether the chair feet are equipped with anti-slip pads to protect the floor and prevent sliding.
Corner treatment: Is the edge smooth to avoid safety hazards caused by sharp corners.

7. Environmental protection and health
Environmentally friendly materials: Is the material with low formaldehyde content used? Especially for wooden dining chairs, it is recommended to buy products with environmental certification.
Odor detection: Smell whether there is a pungent smell. Inferior materials often have a distinct chemical smell.
