Best computer chairs — TOP 10 rating of good chairs

Have you ever wondered how much time you spend in a computer chair? With a standard 8-hour working day in the office — at least 1900 hours a year, not counting the time that you sit at the computer at home. In total, every year you are in a sitting position for at least 80 days without a break. A good reason to take a fresh look at the ergonomics of your workplace — after all, the design, swing mechanism, dimensions of the chair affect the health of the back and the body as a whole. We tell you how to choose an ergonomic and practical computer chair in order to reduce the load on the spine, and at the same time not overpay.

How to choose a computer chair

Ergonomic office chair with good lumbar support and easy height adjustment, its frame is solid and the upholstery is made of non-staining and breathable materials. The design of modern chairs often contains additional elements that increase comfort, such as headrests, orthopedic inserts, and a rocking mechanism.

To ensure that the office chair meets your needs, pay attention to the following details:

Lumbar support. The back of a computer chair must be physiological. When you sit, your lower back should have a comfortable curve so you don’t slouch when you get tired. A good chair may have an adjustable lumbar pillow.
Adjustment. Many modern computer chairs can change the working position: adjust the backrest and seat height using the gas lift control lever. For some models, it is possible to change the height of the backrest and the depth of the seat, the location of the armrests, and the elasticity of the swing. It’s good if the purpose of the levers is intuitive — instructions are often lost.
Wheel base. Usually, office chairs have a caster base — this makes it easier to move around and eliminates sprains and uncomfortable postures when you need to reach documents or office equipment. But the characteristics of the wheels themselves are also important. For carpet, wheels with maximum freedom of rotation are suitable, and for a room with a smooth surface, choose a chair with rubberized rollers.
Swing mechanism. Deviating from time to time, you can change the working position to improve the blood supply to the intervertebral discs. The swing mechanism is more often present in models of medium and high cost. Various design solutions are possible: top gun, permanent contact, deeptilt.
Upholstery material. Office chairs can be upholstered in fabric, natural or artificial leather, or with a mesh surface. Eco or natural leather looks solid, easy to clean. However, such a surface does not pass air well, so it will be uncomfortable to stay in the chair for a long time. The fabric is versatile and comfortable, but gets dirty more. The mesh surface is well ventilated and reduces the overall weight of the chair, but is harder to clean and less wear resistant.

Choosing office chairs

A well-chosen office chair increases employee productivity and efficiency. On the contrary, an uncomfortable computer chair causes back pain, circulatory disorders in the legs and carpal tunnel syndrome. Choose work furniture, focusing on the status and duties of the employee.

Operator’s seat. The most common and inexpensive variety with basic functions. The owners of the simplest chairs are not even able to swing and adjust the backrest. But there are also full-featured models with a reinforced frame for workplaces where employees are present around the clock.
Chair for senior staff. Computer chairs of this type belong to the more expensive category. For middle managers, comfortable models with a high back, improved support, and armrests are often chosen.
Executive chair. The workplace of a top manager emphasizes the status. The main details of such furniture: good leather upholstery; improved swing mechanism; durable frame with increased load capacity; retractable footrest; headrest.

Office chairs: top 10 best

Our specialists have selected the most interesting office chair models with the best quality-price ratio.

Everprof Ergo Gray

The Ergo Gray computer chair stands out even among the models of Everprof, a manufacturer known for its unusual product design. The back of the chair, consisting of separate movable blocks, adapts to the individual physiology of the person sitting on the chair. Swinging is carried out by a mechanism with asynchronous seat and back deflection. You can adjust the chair height and seat height, as well as move the seat away from the backrest. The upholstery is made of mesh breathable fabric that does not retain air and moisture. Several upholstery colors are available.
BLANES computer chair

The Blanes office chair attracts attention with its elegant, expensive design. It looks great in a representative area, for example, at the reception or in the meeting room. The upholstery of the chair is made of non-marking, easy-to-wash eco-leather, so the model will retain its spectacular look for a long time even in a chic beige design. A well-thought-out adjustment mechanism, comfortable width, swing in a comfortable amplitude — the manufacturer has provided everything so that even a long working day can be spent in this chair without harm to health.
TopChairs Alpha executive chair

The TopChairs Alpha executive chair looks solid, but, among models in its class, is relatively affordable. Thanks to a durable metal frame, the chair can withstand weight up to 120 kg, and soft pillows exactly follow the shape of the body, eliminating back and neck problems. The piastre mechanism is responsible for the swing, a reliable gas lift is responsible for height adjustment, and the recliner fixes the desired backrest angle. If you want to take a break from working at the computer, just lean back and slide out the footrest to relax in a comfortable position.
College Operator’s Chair H-8078F-5

A smart choice for busy offices, the ergonomic and affordable College H-8078F-5. Compact and lightweight chair fits easily in small spaces. Movable wheels make it easy to move it around the floor, and the metal cross is stable and reliable. Although this model belongs to the basic level, it has all the features to make the work of the employee very comfortable: a height adjustment mechanism up to 103 cm, top gun swing, the ability to change the height of the seat. Durable acrylic mesh on the back is anatomical and provides good ventilation.
Executive chair Bureaucrat MONE

The company «Bureaucrat» is known for light models of the budget class, which can be seen in any office in Russia. But under the Bureaucrat brand, higher-class products are also produced, including the MONE chair. The chair differs in the increased endurance — to 150 kg. Other features: elegant black and white pattern design, repositionable seat to backrest, gas lift mechanism for height adjustment, rubberized wheels that won’t scratch or mark hard surfaces. Swinging is implemented according to the «synchronous» system.
Everprof Drift Full AL M

The advantages of the chair have earned it a high rating from buyers. The working surfaces of the chair (armrests, front part of the seat and back) are made of eco-friendly and wear-resistant natural leather. The mechanism for locking the backrest has four positions. The anatomical design of the seat and backrest reduces fatigue to a minimum during prolonged work at the computer. And for a comfortable stay, the chair has a comfortable headrest and rocking through the multiblock system.
Computer chair ARANO

Unpretentiousness, comfortable design and affordable price brought popularity to this computer chair. The metal frame and crosspiece increase durability, while the eco-leather finish is stain resistant. The high back design combines mesh inserts for good ventilation and thick overlays for good lumbar support. The swing is implemented using the top-gun mechanism. The height can be changed from 61 to 115 cm, which allows you to adjust the chair to any height.
Office chair TopChairs SIMPLE

The manufacturer managed to pack good lumbar support and height adjustment into a compact and minimalist design. Rocking as a function is absent here, as is the headrest. However, for a workroom, where a purely business and official atmosphere should reign, this is rather a plus.
Office chair Set 19

Most often, office chairs are sought for universal chairs: durable, non-staining, budget-friendly and comfortable for all employees, regardless of their height. «Set 19′ is such a model. Its advantages: breathable, washable fabric upholstery, comfortable back design with lumbar support adjustment function, a special seat shape that prevents swelling and leg cramps, a heavy-duty steel frame with a 10-year warranty. Adjustment options: gas lift for height change and high-quality rocking mechanism.
Office chair Bureaucrat CH-605

An interesting design chair at a great price. It is suitable for a small office or home. The model is reliable and easy to adjust: the swing of the back using a spring-screw mechanism, a gas-lift system for changing the height, a stopper on wheels that prevents accidental rolling when you get out of it.

The best computer chairs for the home: affordable and comfortable

The main difference between home computer chairs and office chairs is that people usually spend their leisure time at home computers. For the home, gaming chairs are often bought — a type of computer furniture that is almost never found in the office.

The first gaming chairs were designed for computer racing — that’s why even today many gaming chairs resemble the shape of racing car seats.

What to look for when choosing a gaming chair:

Comfortable armrests. For computer users, the armrests are not as important as the forearms can rest on the table next to the keyboard. But the hands of gamers are often stretched out or are on weight, and for a long time they keep the same position — ergonomic armrests in this case are not a luxury, but a necessity.
Back support. If an office worker needs vertical support to keep from slouching at work, a gamer’s chair should provide a comfortable body position in the reclined position. Neck support is also needed, so a gaming chair needs a high back, a comfortable headrest, and lugs that fix the position of the shoulders.
Materials. It is difficult for an enthusiastic gamer to tear himself away from his favorite game even while eating. Traces of spilled coffee or greasy stains from an eaten hamburger can remain on the fabric surface, so the most practical materials for finishing a gaming chair are leather, eco-leather or PVC.
Dimensions. In order for the ergonomics of the chair to work in your favor, you need to choose its dimensions well. It will be uncomfortable for thin people of short stature to lean on the armrests of a large chair, on the contrary, for large people in a chair that is too small, there will not be enough back and neck support.

Abstract

The article describes an approach for determining the bearing capacity of light steel thin-walled structures based on computer simulation using a deformed scheme. Calculations were carried out for two fundamentally different profile configurations: a traditional C-shaped profile and a modified Atlant profile. The obtained results are compared, and their “sensitivity” to various input parameters (metal thickness, profile wall height, etc.) is analyzed.
