How to choose a comfortable chair for home or office?

According to ergonomic indicators, a comfortable work chair should meet the following parameters.

Office chairs can be divided into two categories: staff chairs and executive chairs

The seat. The length and width of the seat must be at least 40 cm. The seat height should be adjusted within 40-50 cm, and its slope up to 5-150. The seat can be hard, semi-soft and soft. Preference should be given to a semi-soft seat, and with a denser filler in the centre and a soft filler around the perimeter.

The back. The height of the backrest should be at least 30 centimeters, and its width should be at least 38 cm. The backrest tilt should be adjustable within 30 degrees in each direction. When adjusting the backrest, choose not a right angle, but one exceeding 900. It is better that the backrest be anatomically shaped, i.e. one that will repeat the contours of your back.

Armrests (they can be removable) must be at least 25 cm long and 5 cm wide. Their height must be adjusted. Remember, the main task of armrests is to support a person when he gets up or sits down. Please note that the armrests should not rest against the table when you try to move towards it.

Bracing. In simple models of chairs, the parts are fixed immobile in the adjusted state. But there are also more modern models equipped with so-called synchronization and swing mechanisms. The first allows you to change the tilt of the seat and backrest at the same time. The second one provides a pleasant rocking on the chair, which helps to distract and calm the nerves. The rocking mechanism is designed so that during relaxation, the legs continue to remain on the floor. This is very important, since in this position the legs will not go numb.

Theoretically, everything is simple. What is in fact?

A chair with a headrest will relieve the load from the neck and reduce the degree of fatigue

When choosing a chair in the store, be sure to sit in it. Correct posture — feet should be on the floor, elbows on the armrests, while shoulders should remain relaxed. You should not feel tension in the lower back and neck, and the back of the chair should support your posture, so that you can sit comfortably and work at the same time.

In addition to whether you are comfortable sitting, pay attention to what happened to the chair when you got up from it: it should not creak or sway. Look at how the wheels work, they should slide smoothly on the floor. In addition, check the operation of all adjustable parts of the chair. The height, tilt and position of the seat, backrest and armrests should be adjusted smoothly, without creaks and special efforts.Please note, the best work chair is the one that can be adjusted without getting up from it. All functional levers should be located where you can freely reach with your hand.

Material quality

Another important criterion for choosing a chair is the material from which it is made. Manufacturers prefer adjustable and metallic bases. You can also find a wooden one, but it will be quite expensive and less durable.

An equally important part of the chair is its lining. A high-quality chair made of environmentally friendly materials will allow the skin to breathe and maintain the same body temperature. Depending on the low-cost, you can choose leather, its substitute or high-quality synthetics. The most important thing is that the surface of the chair does not slip and does not electrify. Also, the material should be breathable, wear-resistant and easy to clean.
