It is not about looking for the most comfortable chair possible, since this design is completely far from ergonomics. The first thing we must take into account when looking for a chair to work is the posture that the body adopts, an upright position where we lightly rest our back on the backrest.
Ergonomic chair, what should you have?
With very few exceptions, if you are looking for an ergonomic chair, you should completely exclude gaming chairs, chairs that prioritize a sporty design over everything else, including ergonomics. For a while, they do the job perfectly, but if you plan on spending a lot of time in front of the computer, you should remove this type of chair from the equation.
For a chair to fall into the ergonomic categories, it is essential that it includes wheelsto be able to move the desk without having to get up or continually drag the chair with our feet. Furthermore, we must also allow turn the seatfor the same reason as the casters, to allow users to move comfortably around the table and always have what they need close at hand on the sides.
Because not everyone has a standard measurement, it is necessary that the chair allows for adjustment of the chair height so that the knee makes a 90 degree angle with the ground, where the foot must be fully supported. In this way, we avoid forcing both the soles of the feet and the pelvis.
Here we must also take into account the table height and the monitor since this also includes the position we adopt. As far as possible, it is recommended that the elbows form a 90 degree angle on the table to prevent these joints from becoming damaged over time. If we are thinking of changing our desk, it is important to take into account this very important little detail.
Although many models do not include the ability to adjust seat depthThis is also important, especially for very tall or very short people, because it allows the angle of the knees to be adjusted, thus allowing the back of the chair to be used in an upright position, avoiding curvature of the back.
Also regarding tall and short people we also need to take into account the backrest height. If it is a tall person whose backrest only covers half of the back, the adopted posture ends up having an impact on the cervical spine, the same problem encountered by short users whose backrest completely covers the head, since they are forced to force the cervical spine without the possibility of resting it on the upper part.
In addition, the upper part must incorporate a support that allows us to comfortably place the neck when we need to take a break or a more padded area than the rest of the backrest. As for the armObviously, if you have them, it’s even better, but if we take into account that we rest our arms on the table and not on the seat, whether they have more or less additional functions (whether they rotate or tilt) is completely secondary.
Respect to lumbar supportSome chairs offer too much design in this area, forcing the user to change the way they work, so it is not a good option to consider, as long as it does not stand out excessively, as is usually common in gaming chairs.
Another very important aspect that we must also take into account is the material used. To avoid cold and excessive heat, especially during the summer months, we must always choose breathable materialsmain fabrics if possible, forgetting synthetic materials such as synthetic leather which, although very beautiful aesthetically, does not facilitate body perspiration. It is also important that it is easily washable and elastic to prevent it from wearing out or even breaking at the first change or due to the continuous friction of the clothes we use.
