How to choose a computer chair: device, characteristics

Five rocking mechanisms to create your comfort
Are you sure that you have configured your rocking mechanism as conveniently as possible and used all its capabilities? If you doubt the answer or are looking for a new five-wheeled friend, is this article for you?

According to the calculations of scientists (not British, but normal ones), throughout our lives we spend a little more than 10 years at work... That is why ]armchairs[/anchor] around the world decided: “Let these be the best 10 years of your life!”, and equipped with a huge number of adjustments. It’s more pleasant to spend so much time in soft, comfortable chairs, isn’t it?

If you are asking philosophical questions, “what kind of lever is this” or “why is there this huge screw” in your chair, or are you looking for a new friend on wheels, this article is a must-read for you.

Let's look at the most common swing mechanisms for office chairs!

What rocking mechanisms can chairs have?

Piastra

Quite a poetic name for that harsh thing in the photo below, don’t you agree? Thus, a piastra is a device that allows you to adjust the chair exclusively in height. Up down. And that is all.

It is a block with a gas lift control lever, which, in turn, has the magical power to raise and lower your chair. Typically used in low-cost operator models.

Permanent contact

Along with piastres, you can often find permanent contact . It is based on an elastic spring, which allows the back of the chair to press against the back of the person sitting and, accordingly, regulates its angle and fixation.

In total, it has 3 adjustments :

• back height
• planting depth
• backrest deflection rigidity

FDA (spring-screw mechanism)

Another device for connecting the seat and back of the chair is the PVM (spring-screw mechanism) .

It has only 1 adjustment: backrest swing stiffness. The interesting thing is that the backrest here is not fixed in any position - initially it is vertical. But when you lean on it, the front actuator is activated, and the backrest tilts depending on your contact force (or weight).

Top gun

The top gun, or centered swing mechanism, or DMS is a “rocker”. Such devices are used in executive chairs.

The top gun has three adjustments:

1. Up and down, using a lever that acts on the gas lift and raises or lowers the chair.
2. The same lever, if adjusted not up and down, but right and left, activates the swing mechanism, or, conversely, fixes the chair in the working position.
3. The mechanism contains an adjusting screw, which allows you to adjust the rigidity of the swing depending on the weight of the person sitting.

The mechanism is called “centered” because its axis is located in the middle of the chair, which means that when the chair is fully tilted, the seated person’s feet are lifted off the floor.

In more expensive models (which have a multiblock with an offset axis, which we will talk about later), the swing axis is shifted closer to the edge , and therefore it is more comfortable to swing: your feet are on the ground.

Deep Tilt

Deep Tilt , or deep swing mechanism , or knee mechanism , is a device that allows you to turn your warhorse into a virtual rocking chair.

1. The lever on one side is responsible for raising and lowering the chair up and down.
2. The lever on the other side is responsible for swinging and locking in the working position.
3. The mechanism contains an adjusting screw that allows you to adjust the rigidity of the swing.

To roughly generalize, the functions of Deep Tilt are the same as those of the top gun. A separate lever is allocated only for swinging, which allows the chair to swing stronger .

Deep Tilt is not very common in Russia, but to get the overall picture we decided to add it to the list.

Multiblock

The good old and beloved chair transformation mechanism . It has all the top gun adjustments, and what's more:

• Allows you to adjust the force of deflection of the chair during swinging and its rigidity
• Fixes the chair back in several positions (up to 5 positions)

Multiblock with an offset axis is a variation of the multiblock that ensures constant contact of the feet with the floor, no matter what the tilt of the chair is at this moment. Such a mechanism can be found in ergonomic, comfortable models of executive chairs.

Multiblock with synchro mechanism

The synchro mechanism changes the angle of inclination of both the back of the chair and the seat separately, but all at the same time. In other words, when rocking, the seat and backrest move separately from each other, but in a certain proportion to the angle of inclination. As a rule, the optimal proportion is a ratio of 3:1. Backrest tilt 3 degrees = seat tilt 1 degree.

The tilt range of the chair back is 30-36 degrees. At the same time, any synchronizing mechanism is necessarily equipped with load adjustment for personal adjustment to your weight in order to ensure maximum unloading of the spine.

Multiblock with asynchronous mechanism

The asynchronous mechanism performs exactly the same functions as the synchronous mechanism, but at the same time the back and seat tilt independently of each other, following the movement vector of the seated body.

In other words, when you rock on a chair, the backrest swings with you, but the seat remains fixed in one position. Or vice versa.

Choosing a chair

When planning to buy a chair for your workplace, you should carefully study the swing mechanism.

Every person wants to sit correctly and comfortably.

This feature was invented to create maximum comfort for a person who spends a lot of time in a sitting position.

When buying a chair, “try” it yourself: if it’s comfortable, feel free to take it.

To avoid negative consequences such as poor circulation, spinal problems and others, it is necessary to pay attention to how the chair can adapt to the individual characteristics of the human body, providing it with comfort.

A person’s well-being and performance will directly depend on the stool.

Rotation mechanisms should be oriented towards the ergonomics of the human body position.

It is also important to choose a chair to your liking. So that it matches your ambitions and is perfectly displayed in your image in your personal account.

What other additional mechanisms exist in nature?

In addition to the above, the chairs may contain:

• Multi top gun , or top gun deluxe , or DMSL - this is a more advanced version of the top gun from the point above. The difference from the basic top-gun mechanism is the presence of a lever for fixing the chair in any convenient position. Actually, this is what makes it “luxury”.
• “Anti-shock effect” is a mechanism that independently smoothly returns the chair to its working position after unlocking. This means that you do not receive a sharp push in the back from your favorite (or no longer?) chair, but calmly return to your working position.
• A slider is a device that regulates the depth of the seat (it can “move” back and forth and lock in 5 different positions, moving the back of the chair further away or closer to you).

Phew, figured it out! And now – our TOP 8 most popular office chairs – look, study, buy!

Piastra

This mechanism is the most basic; it is installed on inexpensive models of mass-produced computer chairs. The plate is a lever block that controls the position of the gas lift. The plate performs one function: it fixes the height of the office chair. The plate controlled gas lift is the supporting element and connects the beam cross member to the seat base. Under the action of the lever, the piston stroke in the gas lift is turned on and the user adjusts the convenient position of the product.

The main advantages of the device are simplicity, reliability and low cost. But there is a limit: an office chair with a plate mechanism is suitable for those who intend to use the selected furniture no more than 3 hours a day. If you spend more than 3 hours in a work chair, you should take a closer look at more advanced mechanisms with adjustable backrest angle.

Dry cleaning of office chairs

The seat upholstery wears out a lot with daily use, especially for furniture in the workplace. When purchasing chairs for the office, you need to be prepared that the soft covering on the seats and backs requires periodic cleaning. This work is carried out as it gets dirty; the products used depend on the type of material (leather, synthetics, cloth).

Technology for dry cleaning chairs:

1. Cleaning the surface with a vacuum cleaner to remove dust.
2. Difficult stains are removed using safe stain removers and cleaned.
3. If it is heavily soiled, you will have to completely cover the upholstery with the cleaning compound several times.
4. High-quality cleaning of products is done using professional special washing vacuum cleaners with two hoses for supplying and removing soap solution.
5. If necessary, gently dry the upholstery with a hot hairdryer.

Office chair - characteristics

This type of furniture is radically different from a simple stool or lounge chair. Products intended for long-term office work in an almost unchanged position at the table must optimally suit the person in terms of height and other anthropological data. When choosing a chair for an office or study, it is advisable to compare the characteristics of the samples you like. A photograph or a quick inspection of the appearance of a display case does not provide complete information; when studying the passport, familiarize yourself with the following parameters:

1. Upholstery and frame material.
2. The presence of adjustment mechanisms (height and depth of the backrest, tilt angles).
3. Dimensions of the assembled product.
4. If you purchase a folding office chair, then you need to know its dimensions, taking into account all the adjustments.
5. Color and design.
6. The weight of the product itself.
7. Maximum weight load on the seat.
8. Cost.
9. Manufacturer.

Designer office chairs

Mass-produced furnishings are easier to find and are comparatively cheaper, but this approach does not suit a creative person. Unique products always find admirers. A designer office chair is suitable for a person trying to stand out and make the interior of their office unique. The main thing is that stylish furniture with unusual shapes meets the standards in terms of basic parameters, and spending a long time in such a chair does not have a negative impact.

Examples of designer office furniture:

1. Designer chairs with floral patterns.
2. Designer chairs in a futuristic style.
3. Designer leather executive chair.
