1. Key points for purchasing: Stools are essential items for home life. We must consider height, material, and appearance when purchasing. and other factors to ensure practicality and durability.
Height: Stools can be tall or short. When purchasing, we should judge different heights according to the location and the people who use them. For example, the stools in front of the dining table should be taller, especially for children. The height should be higher than ordinary stools. Adults are slightly taller. If you are sitting at the coffee table, the stool in front of the TV will be much shorter. Generally, it is necessary to ensure that the center of gravity of the person with his feet on the ground can be well fixed, and the lumbar spine will not be too stressed, which will help to decompress the lumbar spine. .
Material: There are various materials for stools, but you cannot choose them arbitrarily. They must be judged according to the use environment. Wooden stools are not suitable for humid environments. If they are used by children or the elderly, Choose a stool with a slightly softer surface, otherwise sitting for a long time will cause discomfort and damage the spine.

Tips for buying stools/bench
1. Look at the appearance. When purchasing a stool, we need to check whether the surface is smooth and flat, and whether there are any burrs, horizontal rows, etc. If it is easy to scratch clothes or scratch the skin when using it, be sure not to choose it.

How to choose a comfortable stool?
1. People of different heights may have different comfort levels with stools. First of all, when our feet are flat on the ground, the thigh and calf can form approximately a right angle, or the angle between the thigh and calf is approximately 100 degrees.
2. Secondly, the seat surface of the stool cannot cause pressure on the lower surface of the thigh. Try to ensure that the distance between the back of the knee and the edge of the stool is about 5 cm to avoid pressure on the knee by the edge of the stool seat surface. , causing numbness in the legs.
3. When purchasing a stool, in addition to the height of the stool, you must also consider the comfort of the stool. First of all, the design of the stool must be ergonomic. Second, the stool must have strong support to ensure that we have sufficient safety when sitting on the stool. Third, the chair back can retain the natural curve of the human body's back, which can ensure the comfort of the back when sitting on the stool.
4. Finally, on the premise of ensuring the comfort of the stool, the aesthetics of the stool should also be taken into consideration. After all, placing a stool at home is also part of the home design. Buying a good-looking stool will make you feel much better. To sum up, a good stool must have three characteristics: beauty, durability and comfort.
What is the size of the stool?
1. Sitting height refers to the vertical distance from the seat surface to the ground. Since the chair surface often tilts backward, the seat height of the stool is usually taken as the height of the front seat surface; if the seat surface is tilted backward or has a concave arc shape, the seat height refers to the vertical distance from the center point of the front seat to the ground. Proper sitting height: thighs should be kept horizontal, calves vertical, and feet flat on the ground.
If the seat height is too high, the legs will be suspended in the air, which will compress the thigh blood vessels; if it is too low, it will cause physical fatigue. Practice has proven that the appropriate seat height is the height from the calf socket to the sole of the foot plus the heel thickness of 25mm-35mm, minus 10mm-20mm of movement margin.
That is: sitting height = calf socket height + heel thickness - appropriate gap. The national standard GB 3326-1997 stipulates: sitting height is 400mm-440mm, and the size difference is 10mm.
2. The sitting depth refers to the distance from the front edge to the rear edge of the chair surface. The sitting depth has a great influence on the comfort of human sitting posture. If the sitting depth of the stool exceeds the horizontal length of the thighs, the human body will have a large inclination when touching the backrest, and the waist will be suspended due to lack of support points, which will aggravate the intensity of muscle activity in the waist and lead to fatigue; at the same time, the sitting surface is too deep, making the knee socket Produces a numbing reaction and is inconvenient to stand up.
The average horizontal thigh length of the human body in our country is 445mm for men and 425mm for women. Then ensure that the front edge of the sitting surface is a certain distance away from the inside of the knee (about 60mm), so that the sitting depth is generally 380mm. ~420mm.
3. The width of the seat surface of the stool is often wide in front and narrow in the back according to the person's sitting posture and movements. The front edge width of the seat surface is called the sitting front width and the rear edge width. It is said to be wide after sitting.
The seat width is generally not less than 380mm. For chairs with armrests, the support of the human arm must be considered. The inner width of the armrest is used as the seat width, and the average shoulder width of the human body is added. An appropriate margin is generally not less than 460mm, but it should not be too wide. It should be based on the comfortable shoulder width of the naturally hanging arms.
4. When people are resting, they sit leaning backwards to support their lumbar vertebrae. Therefore, most general sitting surfaces are designed to tilt backwards. The inclination of the sitting surface is generally 3 to 5 degrees, and the opposite chair back is also tilted backwards.
5. The size of the backrest is mainly related to the height from the bottom of the hips to the shoulders (determines the height of the backrest) and shoulder width (determines the width of the backrest). The height and width of the chair backrest, the height of the backrest can reach 480~630mm, and the width can reach 350~480mm.
6. The height of the armrest should be close to the vertical distance from the ischial node to the lower end of the elbow when the body is naturally drooping. Practice has proven that the appropriate vertical distance from the upper surface of the armrest to the seat surface is 200mm-250mm.
At the same time, the front end of the armrest should be slightly higher. As the inclination of the seat surface and the backrest angle change, the inclination of the armrest generally varies from 10 to 20 degrees, while the armrest has a gradient of 10 degrees on the horizontal left and right sides. within the range is appropriate.

How to choose a chair
1. Seat height
Should be equal to the length of the calf. After sitting down, the calf will naturally droop and the soles of the feet will just hit the ground. If it is too high, the calves will be hanging, and the lower part of the thighs will be under too much pressure for too long, which is not good. If the seat surface is too low, the thighs cannot be placed on the seat surface, and the body weight will be concentrated on the buttocks, which will be uncomfortable for a long time.
2. Seat depth
For a chair that is mainly used for sitting, the depth of the seat surface should be equal to the length of the thigh. After sitting down, the bend of the knee joint just reaches the edge of the chair. The seat surface is too It's deep, and there's no support for the lower back; the seat surface is too shallow, and there's not enough support for the thighs, making it uncomfortable.
3. The materials of the surface and chair back
Both should be "soft on the outside and rigid on the inside" - the bracket should be strong enough, but have a certain thickness of elastic layer on the surface . The outermost material in contact with the human body should be breathable, wear-resistant, and dirt-resistant, and should not easily generate static electricity on the human body or clothing.
4. Chair back
It can fully or partially support the waist, back and neck. The longer the chair you sit on, the better the support must be. Because the dining chair is only used when dining, the neck can be ignored, while the office chair can take care of it. The size of imported furniture is often more suitable for people in the country of production, so you need to pay special attention when selecting.
