You may or may not be aware of the serious health consequences of an extended session and why this is a concern for all of us who spend more than 30 hours sitting at our desk each week.
Sitting causes a series of tensions in our body, especially in our spine, and this has recently started to be more recognized by medical professionals, and is the main reason for the sudden rise of ergonomic chairs.
What does the term "Ergonomic" mean?
Ergonomics is a science, also known as human engineering or biotechnology. The discipline consists in observing how objects can be designed and / or organized to better complete an easy and safe human interaction.
An ergonomic chair, for example, is a chair that has been designed to better support the human body, including considerations such as posture, comfort, support and health.
What makes a chair ‘Ergonomic’?
Best Ergonomic office chairs have several features designed to improve your posture and provide good support, but they only do half the work - To really experience the benefits of an ergonomic chair, you must first learn to sit properly.
Salient Features of an Ergonomic Chair
1. Seat height
The ideal seat height should allow you to put your feet on the ground, which is why the choice of a height-adjustable chair is essential because everyone is different. In addition, since most work tables remain at a fixed height, it is important that the seat height can be changed. A seat height ranging from 16 to 21 inches from the ground should work for most people.
2. Seat width and depth
The proper seat depth should be between 2 and 4 inches between the edge of the seat and the back of the knees. If the seat is too far forward, you can put excessive pressure on the back of your knees.
3. Seat tilt
best ergonomic chairs will allow the seat to tilt, which allows the correct positioning of the pelvis. Anterior pelvic tilt is a posture problem that affects almost everyone who sits a lot, so it's important to keep the pelvis in a neutral sitting position, with 80-degree angles at the hips, knees and ankles.
4. Backrest Lumbar support
It refers to the support provided to the lower back and is an essential feature of an ergonomic chair. Ergonomic chairs support the natural "S" shape of the spine, preventing falls and reducing stress on the spine and pelvis.
An adjustable backrest allows users to align the seat curve with the column curve for optimal support.
5. Backrest Recline
An adjustable backrest allows better personalized positioning for the user, as it can move the backrest to more specifically support the natural position of the spine.
Using this feature throughout the day allows the back to remove some of the upper body weight, reducing the pressure on the discs and muscles of the spine.
The armrests help reduce tension in the upper body and allow the shoulders to relax. However, the armrests should not be used when typing, as this reduces the general movement of the arm, which increases the movement of the wrist, causing tension in the muscles of the forearm.
