The importance of sitting properly to work more efficiently has become a key factor in the last few years. Consequently, people now choose carefully the most suitable office and home chairs, in order to ensure a healthy posture and prevent the onset of bone and muscle disorders. Ergonomic chairs guarantee a healthy, correct and “custom” posture, adapting to the anthropometric characteristics of the user and complying effectively with many different needs.
To sit in a physiologically correct position, make sure that:
- the sole of the foot rests on the floor;
- the foot forms an angle of approx. 90° with the calf;
- the calf is roughly in a vertical stance;
- the calf forms an angle of approx. 90° with the thigh;
- the thigh is in a horizontal stance;
- the thigh forms an angle of approx. 90° with the chest;
- the chest is in an upright position.
How to achieve this posture? What factors need to be considered when choosing the right ergonomic chair?
The height of the seat must be easily adjustable through a gas pump or a gas piston, which allows a configuration adapted to the specific body of each user. The ideal position is the one that allows you to keep the entire sole of the foot completely resting on the ground.
An ergonomic chair must feature lumbar adjustments both in height and in depth, so as to guarantee users adequate support for the lower back. The spine curves inwards right in this area, therefore, if you sit for a long time without proper support, it tends to flatten, causing tension and pain in the lumbar area. The presence of a support allows you to adjust the thrust in the back-lumbar area, thus benefiting from better support for the back.
Adjustable in height, depth, direction and width, armrests are an essential support to properly and comfortably rest the arms and to relax the shoulders. It is important to find the right adjustment for your own body, so as to give continuity with the height of the desk and the computer keyboard.
From 30 to 50 cm wide, this element gives support to the back, in particular to the lumbar area and correctly balances the weight of the spine, giving relief to the shoulders and neck. It is important to mention that the ergonomic backrest must be tiltable and the lumbar supports must also be adjustable in depth.
The mechanism is one of the key components of an ergonomic chair and represents its “core”. These systems allow you to adjust the tilt of the backrest and the depth of the seat. The most innovative models allow a 360° movement, which supports and follows the user’s gestures and movements.
Another key factor when choosing an ergonomic chair is the upholstery used for the seat and backrest. Elastic, breathable, soft and comfortable fabrics are preferable, in order to cushion movements effectively.
Be careful, though: excessive comfort can be counterproductive! It leads to bad posture, which could result in back and body problems and eventually cause functional and aesthetic damage.
Ergonomic chair is synonymous with greater wellness and productivity, an excellent remedy for back pain and inactivity!
