Choosing the right computer chair is a responsible matter that does not tolerate rushing and buying the first item you come across. Work productivity and, more importantly, health depend on what we sit on.
Often, office workers use the most ordinary wooden chairs. In home use, even a stool can play the role of a computer chair. All this leads to discomfort and various problems with the spine. We will tell you how to choose a computer chair in this article.
Chair design
The back of a good chair follows the anatomical curve of the spinal region. The level of the upper edge of the shoulder blades is taken as its optimal height. The shape should not be too concave, as this can lead to scoliosis or pinched nerve endings.
A well-made backrest serves as support for the spinal column without straining it. Some chairs are equipped with reclining mechanisms, so you can even take a nap in them.
It is recommended to choose a seat not flat, but with small protrusions at the edges. This will prevent it from slipping.
The size from floor to seat is determined based on the height of the table and the anthropometry of the person. Your knees should not rest on the tabletop, and your feet should be on the floor without dangling in the air. Raising and lowering is carried out by gas elevators.
Armrests relieve some of the load from the spine. The best option is removable elements.
For complete breaks at work, you will need a headrest. It can be built into the chair (a soft cushion at the top of the back) or taken out separately.
To understand whether a chair is ergonomic or not, try it on yourself before purchasing. If this is not possible, then consider models with adjustable parts.
Choice for schoolchildren and children
Before purchasing a computer chair for a student, you should familiarize yourself with several important rules:
Orthopedists advise to form correct posture, especially since boys and girls in the modern world have to spend quite a lot of time with computer equipment. Therefore, having an orthopedic back will not be superfluous. This design should reach the shoulder blades, which gives the muscles the appropriate tone when sitting;
Muscles develop when there is no additional support. Without armrests - the model is more preferable for shaping the figure and growth;

The thigh and shin should be at right angles. When there is height adjustment, this makes it easier to control this fact;
Ergonomics. The seat should have a slope at the front, a base at the sides and a recess near the base of the back. This prevents squeezing of blood vessels, ensuring normal blood supply to the legs;It's better when you can rock slightly on a computer chair for children. Such relaxation in pauses between classes or games has a beneficial effect on work. Sitting still for more than 30 minutes is challenging. Therefore, when the structure has a mechanism for swinging, it is good both for the child and for a long service life.
When asked where to buy a computer chair, we recommend turning to the Internet for relevant information. There are many websites that provide complete information including addresses and opening hours of stores. Orders can be placed through online stores.
Upholstery material
The list of the most popular materials includes durable fabrics with a high density of thread weave, mesh fabrics and leather.
Genuine leather is quite an expensive pleasure. In attempts to save money, they often resort to leatherette, which, unlike its natural counterpart, “does not breathe.” For air exchange processes, it is better to purchase chairs with mesh inserts.
Nuances
The basic requirements for computer chairs are stated above. Let's take a closer look at a few nuances:
- the chair must be stable, it does not tip over if a person leans back;
- the wheels should rotate well and be durable;
- The swing mechanism allows a person to sway in the chair, which relieves tension in the back muscles.
Another useful feature is the presence of a retractable footrest. The most successful models are shown in photos of computer chairs.
Pros and cons of home models
Constantly working at a computer at home requires the creation of appropriate conditions. Here the best solution is an office-type work chair. The most comfortable position comes first. When a PC is a source of relaxation and entertainment or is used only for viewing news and mail, then a conventional design, even a simple chair, is sufficient.
It is important how a chair or chair standing in front of a computer looks in the overall interior of the room. After all, they can differ greatly, if not contradict each other. When choosing, you should first consider why you wanted to purchase this particular model.
For choosing computer chairs for the home, he says that:
- their cost is lower than the cost of models for office work;
- looks “homemade”;
- matches any style of interior decoration.
There are also advantages to buying a working model for your home. This:
- high functionality and adjustability;
- upholstery material lasts much longer. However, the price is correspondingly higher. In addition, among the huge selection, it is almost impossible to find a model that matches the style of your home interior.
There are combined options on sale, where only the back and soft seat are wooden. You can take a closer look at models with a semi-soft back, depending on how profitable such an acquisition is. The main difference between the home version and the office chair is the exact opposite of rigidity and ergonomics.
Another feature is the presence of armrests. You can later purchase them separately. The choice is offered from:
- hard;
- soft;
- plastic;
- metal.
Computer chair for children
Caring parents buy only safe computer chairs for their children. It is no secret that many diseases of the musculoskeletal system arise as a result of the use of poor furniture products.
Requirements for child seats:
- maintaining an even posture;
- reliability - the child can use the chair as an element of the game, organizing a kind of race;
- prevention of blood flow disorders.
Among the entire assortment, models with an orthopedic effect should be highlighted separately. Thanks to transformation devices, they “grow” together with children. With their help, you can adjust the parameters to the age and physique of the child.
When buying a child seat, pay attention to the presence of regulators, the braking system of the wheels, the size of the crosspiece (at least 530 mm), hypoallergenicity and safety of materials.
Interesting types of chairs
A modern computer chair is a knee chair. Outwardly, it resembles a rocking chair with an angled seat and a knee rest. In such products, the correct lumbar deflection is forced to form.
The design has only one drawback - numbness in the lower extremities. From time to time you need to get up and stretch your legs.
The “dancing” chair looks even more unusual. A distinctive feature is a movable seat with one central fulcrum in the form of a hinge. There is no backrest.
A sitting person must maintain balance, which is achieved by correct posture. The advantage of such a chair is that the muscles and vertebrae are constantly in motion, which improves oxygen exchange in the blood.
Functional mechanisms
Since today the demand for this product has grown greatly, manufacturers produce different models that are radically different from one another. The main difference is the operating mechanism, which performs all the customizable functions of the chair:
- Piastra. A simple mechanism usually used on cheap chairs. Adjusts the seat height by pressing the lever. Sometimes there is a more ingenious design (spring-screw mechanism) that also adjusts the backrest.
- Top gun. A complex centered mechanism that allows the chair to be used as a “rocking chair”.
- Synchromesh mechanism (multiblock). At the same time adjusts the angle of the seat and backrest.
