Influence of seat cushion on office comfort
Ergonomics is a technology born after the Second World War. In addition to our common shape design, ergonomics actually includes various aspects such as the position arrangement of buttons and the design of explanatory text.
In recent years, "ergonomics" and "ergonomics" have been frequently mentioned on various e-commerce platforms and social media. There are hundreds of emerging office chair brands, especially the long-term isolation, restricted activities and emotional depression caused by the epidemic. People have a new understanding of health, and healthy office is no longer empty talk.
How to judge whether the office chair is ergonomic?
"Sitting in an office can still hurt you", this is a difficult thing for our parents to understand, but nowadays, lumbar muscle strain is very common among young people.
In recent years, Ivyco has carried out in-depth research in the field of healthy office, based on the ergonomic chair Ivyco Healthy Office Research Center has conducted a series of research.
We found that whether it is consumers or brands, the research on office chairs is focused on the backrest support point of the chair, and the impact of the cushion on the sitting posture is often ignored.
1. Choose the right seat size, bid farewell to backache and leg numbness
According to research, when the spine is upright and the body is supported by the front and back to share the force, the factors that can still cause fatigue after prolonged sitting are: unreasonable height and depth of the seat surface.
So even if we use an "expensive" ergonomic chair, improper use can still cause discomfort.
For a comfortable sitting height, the backrest should support the lumbar spine to maintain a normal lumbar curvature. At the same time, there should be a certain distance between the knee popliteal fossa and the front end of the seat surface to ensure smooth blood flow in the legs.
The research shows: comfortable seat height = calf popliteal height + heel height - appropriate margin (generally, the heel height is 25-35mm, and the margin is 10-20mm)
2. Pay attention to the shape of the cushion, open and release the pressure evenly
According to the principles of ergonomics, the most comfortable body pressure distribution should ensure that most of the body mass is reasonably distributed to the seat cushion and backrest with a larger supporting area and a smaller unit pressure.
The Ivyco Healthy Office Research Center adopts the test method of body pressure distribution on the seat surface. It is found that the seat surface with high seating surface comfort will not have high pressure areas, and the body pressure distribution should change evenly, and the distribution of adjacent pressure areas should be continuous.
A comfortable seat surface should be able to fit the buttocks and legs of the human body well. While keeping the ischial tuberosity as the main support point, it should evenly distribute the pressure on the buttocks and legs, so that you will not feel muscle tension and release pressure even after sitting for a long time. Better results.
3. Selected internal and external materials, comfortable and breathable for long-term sitting
For an excellent office chair, the inside of the seat cushion must have an elastic layer of appropriate thickness. The outermost material should be breathable, wear-resistant, and dirt-resistant, and it is not easy to generate static electricity with the human body or clothing due to long-term contact with the human body.
The airtight cushion is easy to form an environment conducive to the reproduction of bacteria and germs, increasing the chance of urinary tract infection.
Our research found that compared with traditional cushions, Ivyco high-strength net fabric is more supportive and fit. As a seat back material, it can fit the 3rd and 4th lumbar vertebrae of the human body and provide elastic support for the waist. It can be used as a seat cushion material , can ensure that the seat cushion has good air permeability, strong load-bearing, comfortable sitting feeling, breathable and not stuffy.
