the Greek word "ergo"=labor and "nomoi"=natural laws. It is a scientific discipline dedicated to analyzing the rules and methods needed to adjust working conditions according to the physical and mental needs of humans. According to the requirements of physiology and psychology of work to protect life and promote the healthiest development of the human being. In other words, the goal is to adapt the work environment to the physical and social needs of people. In our case, it is the chair which, thanks to the shape of seat and other components, makes us sit upright and thus prevent curvature of the spine.
Many people sit for up to 12 hours a day. We sit at work, at home, at the cinema or at dinner. Most of this time we sit in a single position and we overload our spine and the rest of the musculoskeletal system. The spinal discs suffer from extreme pressure, compressing the internal organs and tension is created in the spine and neck. Let's look at it in more detail.
Correct sitting = dynamic sitting i.e. sitting when we often change our position and the mechanism of a chair is constantly adapting and supporting important parts of our body.
We have been dealing with ergonomics in RIM for two decades. We are interested in the movement possibilities of the human body, according to which we create seating furniture to support healthy sitting which activates the lumbar system and back muscles.
Healthy seating = dynamic seating. What is it? Simply put, our chairs are equipped with a mechanism where you can adjust the backrest pressure yourself, ensuring that the chair responds to the movement of your body. As a result, it adapts to every working position, protects the vertebrae and activates the spine and muscles of the body when sitting. It is the complete opposite of the rigid position we often stay in for hours in ordinary chairs.
Many people spend up to 10 hours a day in the office or at their desk. Therefore, the office should meet the needs of our body. You will then avoid back pain, stress on the musculoskeletal system, headaches and joint pain or poor blood circulation to the limbs.
A chair for healthy sitting should support dynamic seating, follow the shape of your back, have height-adjustable backrest, seat and armrest, be able to adapt to your weight and responds to the movement of your body. The chair is an essential part of the office that you should pay the most attention to.
When working at the computer, it is necessary to monitor the position of your shoulders, arms, elbows, wrists and hands. Too high a desk will force you to lift your shoulders and arms, creating an acute angle at the elbows, forcing the wrists up. Your desk should be at a height to keep a comfortable 90° angle at your knees and elbows. Generally, the height of your desk should be approximately 70 cm from the floor. The top of the screen should be at your eye level when sitting upright. Never place the screen or keyboard so that you have to turn your head or torso towards it.
Height-adjustable desks that allow changing the working positions are an ideal option. Changing the positions relieve your spine and musculoskeletal system. Furthermore, modern offices are equipped with zones with ergonomically designed armchairs and sofas that allow you to change the environment and work in a different position. And do not forget to do short exercises during working hours. You refresh your mind and stretch stiff muscles and spine.
The technology of sensors placed in a working office chair to sense how the chair is used and improve user's ergonomic comfort.
One could say that there is nothing easier than sitting. We could sit before we could walk and it was not necessary to think about it. But have you ever realized that you sit for twelve hours a day, most of them in a single stiff position?
In addition to the ergonomics of sitting, we started to focus on Smart Sitting technology at RIM. These are sensors placed in a working office chair that sense how the chair is used. They can alert the user that they are sitting too long, evaluate the utilization and the time spent in the chair.
Sit upright and comfortably, do not lean your back on the backrest. Place one hand under your chin and push up gently. Hold this position for 5 seconds and then relax. Repeat five times.
Sit upright and comfortably, do not lean your back on the backrest. Gently bend your head to the left then place your left hand on your right temple and slowly pull your head to the left shoulder. Hold the position for 5 seconds then relax. Repeat on the other side. Repeat the exercise three times.
Sit upright and comfortably, do not lean your back on the backrest. Press hands together in front of your chest, elbows at shoulder level. Spread your fingers and gently turn the forearm towards the body. Hold the position for 5 seconds and then relax. Repeat five times.
Sit upright and comfortably, do not lean your back on the backrest. Put one hand horizontally in front of you, straighten the palm and bend your fingers down. Use your other hand to stretch fingers. Relax after 5 seconds. Repeat with the other hand. Repeat the exercise five times.
Sit upright and comfortably, do not lean your back on the backrest. Raise one hand and try to reach as high as possible with your fingers extended. Hold this position for 5 seconds, then relax and repeat with other hand. Repeat the exercise five times.

Sit upright and comfortably on the edge of a chair. Do not lean your back on the backrest. Place your palms on the back of your neck, shoulders facing sideways. Bend your torso forward while squeezing elbows towards you as if to place them between your knees. Hold this position for 10 seconds then straighten your back and put hands on your knees. Repeat 5 times.
Sit upright and comfortably on the edge of a chair. Do not lean your back on the backrest. Place your palms on the back of your neck, elbows apart. Hold this position for 5 seconds. Rotate the torso to the left while the elbows are still apart. Stay in this position for 5 seconds. Return to the original upright position and place your hands on your knees. Repeat it on the other side. Repeat the exercise 5 times.
