For many workers, sitting is the most common position. At work, in the car, and at home, they often sit. So they demand maximum performance from their backs because it cannot resist this mono restriction in the long run.
It is not possible to notice an increased back overload after several hours or days, but only after weeks or even months. This leads to permanent spinal damage. A comfortable work chair provides the treatment. How to get to know a comfortable work chair?
What does ergonomic chair mean?
Ergonomic chair mean the chair which has adjustable seat height, armrests, seat depth, headrest, and backrest. The lumbar support makes your lower back and spine in a natural posture. It keeps the spine in the right alignment.
The basics of ergonomics.
To find a comfortable work chair, it is essential to know the principle of ergonomics. Indeed, the “comfortable work chair” is very important for long hours sitting. Each chair has a different dimension and size.
The working environment is a set of optimal conditions in the workplace. It includes not only the seat but also the entire work environment with work equipment and surrounding circumstances. Behind the term “work environment” hides a complex concept for comfortable planning of a workspace.
An enhanced workstation in place and time is practical. The goal of the work environment is to reduce fatigue or harm to people who work while on the job. In many jobs, the workplace is the interface between the employee and the workplace. The more comfortable the employee, the more efficient and concerned about the quality of his work.
Ergonomic seating in the workplace – how it works
During the transition to digital, many of the processes that previously required a step became unnecessary. They are all sitting in front of their screen and not moving enough. This leads to muscle degeneration, tension, back, and headache.
With musculoskeletal inflammation, exercise after work is often unthinkable to make up for lack of exercise. A comfortable and supportive quality is the solution. A comfortable work chair improves physical activity while working.
The comfortable seat has two components: a workbench that can be adapted to the measurements and movements of the person sitting while working—moving while sitting is also important. Flip, fold, stretch are movements that can be made between two movements. Going to the colleagues’ office or walking during lunch completes the active session.
The chair does not promote a comfortable seat. The employee must discipline himself to be active. However, it supports a good seat and encourages movement by supporting the back and stimulating regular position changes through the dynamic sitting position.
This dynamic seat ensures that your muscles stay in motion and are not stiff or contractile. The intervertebral discs are diluted with regular movements, and changes in a position allow constant renewal. Therefore, it remains flexible, and the herniated disc is avoided.
It is important to keep your back straight, even when changing positions. It is very stressful at first. At first, it will be necessary to move to a more comfortable position, but it is recommended to practice an upright posture at all times. This strengthens the back and back muscles better able to withstand the stress of everyday life.
The basis of an ergonomic seat: the ergonomic work chair.
The working chair is the central component of the dynamic seat. It allows and promotes movements while sitting and supports the body in this process. The dynamic seat in the right seat relieves the spine and the less tired body. The ergonomic work chair adapts and supports every movement in the body.
To perform these functions without restrictions, the work chair must be equipped with important components. Not all seats prefer active seats. Mechanics, backrests, and seats should be designed for this. At this point, you can perform the following tasks:
- Supports the body and especially the spine.
- Correcting bad posture.
- Encouraging changing the sitting position.
- Adapt to the sitting person and provide security.
What makes a chair ergonomic?
Swivel chairs are often confused with ergonomic work chairs. However, the ergonomic seat requires more than a wheelbase and height adjustment lever. When buying a comfortable work chair, other features should be considered to allow it to perform its functions.
Each person is different, so the healthy foundation is linked to everyone’s different basic requirements. A comfortable work chair should be able to adapt to these conditions. Therefore, all components must be adjustable. Height adjustment is the most common comfortable seat function.
The correct seat height depends on leg length, foot position, and shoes. The ideal seat height is when the feet are well positioned on the ground, and the knees are tilted at a 90-degree angle. The arms should also be bent 90 ° at the elbow when resting on the table. If the table is too high, a large footrest can be used as compensation.
Properly adjusted armrests relax the shoulder and neck muscles. For everyone to be able to use their armrests correctly, they must be flexible not only in height but also in width. Its width is well adjusted when the arms can rest comfortably, and exercise is not affected. The height is ideal when the elbow is bent at 90 degrees.
One of the most critical elements of a comfortable work chair is the backrest. The standard S shape of the spine must be compatible. In addition to the correct shape, height is also important. The backrest should be adjustable so that the upper edge of the backrest is at least level to the shoulder blades for each user.
If the backrest is not height adjustable, the lower back reinforcement should be incorporated into the backrest to support the curvature of the lumbar spine in advance. The back should always be in contact with the backrest. Even in a slightly folded position, the backrest can support your back. This means that it follows the movement of the seated person and that the pressure adapts to the weight of the body.
The seat surface is adjustable
The ideal seating surface is dynamic and follows the movements of the seated person. Also, the comfortable seat surface of the work chair is adjustable in depth. This is the only way for young people to find enough pelvic support in the back and the elderly to find adequate support for the thighs.
If the backrest is entirely in contact with the backrest, there should be a width of the hand between the front edge of the seat and the knee gap. So there is enough freedom of movement in the sitting position. In order not to impede circulation when sitting, around the front edge is also recommended.
The optimally designed work chair is equipped with a synchronized mechanism that improves the dynamic sitting position. If the body leans forward, follow the seat and backrest. As a result, the back remains straight, and circulation works appropriately.
The synchronous mechanism is a critical criterion for a comfortable work chair because it allows movement in the sitting position. People who focus a lot on work and forget to move automatically change positions during the workday thanks to the synchronized mechanism.
Ideally, the filler material will prevent heat and moisture buildup. For this, it must be breathable, of high quality, and durable. The filling should not give way after a short time. Otherwise, unpleasant pressure points may appear.
This is also the case if the padding is too soft. The padding should be comfortable while sitting, but strong enough to support a daily load without leaving permanent marks.
The pneumatic cylinder is an excellent addition when you have to get up frequently. The pneumatic cylinder covers the position of the seat and helps to get up. This protects the spine from shock. The pneumatic cylinder ensures that the seat surface rises slightly when you are not sitting.
When you sit down, the seat dynamically drops to working height. Shocks that can damage the spine are absorbed, and this makes sitting more comfortable. The muscles are also relaxed. The pneumatic cylinder also supports awakening by pushing the seat up once there is less pressure.
The objective of the work environment is the sustainable health of the active population. So security is also part of the concept. The comfortable seat must be secure in all positions. If the seat rotates or rotates.
Easy to use an ergonomic office chair.
In order for the work chair to adapt to the user without restrictions, excellent ease of use is necessary. Intuitive use is required in all cases where seats are used frequently by different people so that they can be adjusted quickly and easily.
The arms for adjusting the various elements should be easily accessible from the vertical position. Only then can the seat be optimized and take full advantage of its comfortable features. Moreover, easy-care materials and the possibility of maintaining the seat in simple means are part of the excellent comfort for the user.
Digression: stool and sit-stand
Seats and stalls are popular as substitutes for an office chair. It brings changes and saves a lot of movement because the sitting person changes his position repeatedly. Stool leads to an upright posture due to a lack of support and strengthens the muscles of the back for an independent and healthy posture.
To protect your back while sitting avoiding one-sided effort. It is recommended to sit one or two days a week in a comfortable chair. The height must be adjustable and have a seat suspension. The breathable seat padding is also a bonus.
The standing seat supports work in an upright position and reduces legs and feet by supporting approximately 60% of body weight. The best way to sit down at work is to go from sitting to standing several times a day. This creates an ideal balance for all muscles and prevents contractions.
Since standing for a long time is uncomfortable and unhealthy, it is a good idea to use a comfortable seat. The wide seat, the forward-leaning column, and the height adjustment are the minimum requirements for a comfortable seat.
Sitting properly is a matter of adjustment
Sitting health is highly dependent on seating. It must be adjustable to fit a comfortable seat. The basic rule is the right angle. A 90-degree angle at the hips, knees, and elbows is the measure of direction in determining the correct heights. But the most important thing in choosing the right work chair is to try it out.
Movements in the properly adjusted seat should be easy and possible without the hassle. I chose the correct seat if it allowed too much freedom of movement and supported all movements.
