How to adjust the chair swing mechanism, height, backrest tilt

Passive office chair adjustment

Passive settings are achieved without additional mechanisms. This type of adjustment includes adjustment of the armrests. Some models adjust the position of the armrests horizontally or in height.

You can also seal the seat and back to ensure a comfortable fit, evenly distributing the load on the chair. Another mode is a sharp bend at the top edge of the chair. Neutralizes compression of the lower extremities in the area of ​​the patella.

It is advisable to adjust the armrest so that the curvature of the elbows is at least 90°.

Features of computer chairs - benefits and necessity

At first glance, they are all arranged according to the same principle. This is a very misleading impression, causing many to save on their purchase. In reality, each type of seat has different mechanisms, comfort and adjustment. Their main task is to help avoid serious stress placed on the legs and back during long hours of sitting. Because of this, a number of serious disorders with joints and blood circulation develop.

It’s easy to recognize a computer chair, despite the variety of models:

• Cross with rollers. Today, this type of support has confidently replaced chairs with legs from workplaces of all categories. This is explained by saving time when moving. You won’t have to get up again;
• The ability to adjust the height, tilt angle and location of all elements of the chair. An ordinary chair cannot boast of this;
• Availability of gas lift. This mechanism allows you to change the height of the entire structure in several parameters along with you;
• All models are something between an armchair and a stool, retaining the characteristics of both types of furniture.

How to do it yourself

To adjust the parameters of the chair, you should carefully study its design. Some models do not have one or another regulation mechanism. And without them it is simply impossible to set a certain angle of the backrest, the height of the seat and both armrests.

The delivery of the furniture product should include instructions that will help you adapt it yourself. However, you can also use general tips. First you need to decide on the height of the workplace and the depth of the chair. After this, you can begin adjusting the backrest. When everything is ready, all that remains is to adjust the angle and level of the armrests.

Height change

To change the height of the workplace, you need to use the lever, which is usually located under the seat on the left side. Sit in an office chair and raise your pen. Thus, the furniture is lowered to the required level. Next, you need to place your palms on the tabletop, and if you suddenly find that they are higher than your elbows, you need to adjust the position of the chair again. To do this, stand up a little and pull the handle again: without any weight load, the seat immediately rises.

Some seat models may have a rotary adjuster instead of a lever that must be turned to adjust the appropriate seat height.

If the user cannot figure out how to lower or raise a computer chair or office chair and cannot complete the necessary steps, the problem may be:

1. This is not a regular model, but a pulmonary one. To raise the chair or, on the contrary, lower it, the lever must be turned (pressed several times).
2. The design has two regulators, not one. Each is responsible for a specific mechanism (raising or lowering). In this case, we recommend that you carefully study the instructions before setting up.
3. The rotating arm only rotates in one direction. If the chair only rises when you adjust the seat height, you need to keep turning the knob. After a few laps it will begin to descend.

In some cases, the problem may be a design failure. For example, if the height of a chair changes only under the weight of a person (lowers when sitting and rises when standing), then the cause of this phenomenon is a malfunction of the gas cylinder. It will need to be replaced. If the lever on your new computer chair does not work properly (when pressed), it may have been damaged in transit. It needs to be inspected and fixed with pliers.

Backrest tilt

If there is a screw on the back of the chair, it will allow you to recline the backrest. The adjuster should be loosened by turning it slightly counterclockwise, then sitting down and leaning back and forth until you find the most suitable position. After this, you should fix the angle of inclination by turning it in the opposite direction.

Not all office chairs are equipped with screws for adjusting the angle of the backrest: cheap furniture models do not have this function.

Armrest tilt

The armrest adjustment mechanism is usually located on the left side. To adjust the height, you need to press and hold the button, then raise the armrests to the desired level and then release the pressed button.

Another question is how to adjust the tilt. This is done with a special screw. When you slide it, the angle of the armrests will change. If such an adjustment mechanism is not provided by the design, then the actions can be performed using a regular screwdriver. You must follow the instructions so as not to break fragile parts.

To work at a computer or any other activity in which a person’s hands are constantly on the table, it is necessary to adjust the height and angle of the armrests. It is important that the worker's elbows are at a 90 degree angle. If support is not required, it is best to remove or expose these structural parts so they are out of the way (lower or tilt as much as possible at a 45 degree angle).

Some office chair models also offer various adjustment options. For example, the armrests can be extended and moved relative to each other. In addition, the user can be given the opportunity to select certain modes, the number of which varies from 3 to 10.

Prolonged sedentary work often leads to increased fatigue, poor posture, back pain and swelling of the legs. As a result, chronic diseases of the musculoskeletal system and cardiovascular system may develop. This problem affects not only office workers, but also those who spend a significant part of their time at the computer at home.

The cause of such problems can be an incorrectly selected chair, which keeps muscles and joints tense, preventing you from relaxing, and this leads not only to deterioration of health, but also reduces performance. In this article we will talk about what you need to consider when choosing armchairs and chairs for the office.

Changing the seat height

The optimal seat position is determined in an upright position: its highest point should be just below the knee. In this case, in a sitting position, the elbows of the seated person, resting on the surface of the table, should form a right angle. This is the optimal position for long-term work.

The “gas lift” mechanism is responsible for the height of the seat. Optimal comfort is achieved when the thighs are positioned at a 90° angle to the shin. To change the height of the desk chair, you need to use the lever, which is usually located on the left side under the seat. In a sitting position, pull the handle up. To increase the height of the backrest, you will need to stand up, then the height of the seat will begin to increase. When the structure acquires the required position, you need to make sure how correctly the product was secured. Knowing how to lower the chair, you can do it without getting up - just pull the lever.

Some models (instead of a lever) may be equipped with a rotary control, which must be turned to bring it to the desired position. If the owner cannot figure out how to lower or raise an office chair, one of the following will help solve the problem:

1. The product has two regulators, each of which is responsible for a specific action: lowering or raising. Therefore, it is recommended that you read the instructions first.
2. You may have a pneumatic model that needs to be rocked before lowering/raising.
3. The rotating arm can only rotate in one direction. If the chair rises during adjustment, you must continue to rotate. After rising, it will begin to descend.

In this case, the legs must have a strong support underneath them. Legs suspended in the air will not provide the necessary back relief, so the computer chair must be adjusted so that the legs are at a 90-degree angle and the heels rest on the floor or footrest.

What are the sizes of chairs?

Before buying furniture, you need to decide: to order individual production or go to the store for factory-made goods. The dimensions of the chair, no matter with or without a backrest, must correspond to:

• parameters of the table in front of which he will stand;
• the height and physique of the customer.

The main criteria will be the customer’s body type, the purpose of the chair, the room or premises for which the element is purchased.
The table must be purchased in advance, matching the average height of family members. The standard table height is 75 cm.

Manufacturers offer a variety of armchairs and stools of different sizes. They can be fixed or adjusted as needed.

Standard for height and width

For domestic use, GOST provides the following dimensions:

1. Depth: 36-45 cm (40-50 cm if we are talking about a chair).
2. Width: 36-45 cm (40-50 cm for a chair).
3. Backrest bend (location from seat): 16.5-20 cm.
4. Standard backrest – 90 cm.

A chair is a piece of furniture on which it should be equally comfortable to work, relax, and eat.
Standard stool size: 32 cm – width, 50 cm – leg height, 38 cm – distance from the horizontal bar to the seat.

Not only the height of a person matters, but also the length of his legs, the upper half of his body, the height and design of the table.

Custom sizes

Choosing standard furniture allows you to create a comfortable room in almost any case. But in exceptional situations it is necessary to select products with special parameters. For example, if the customer’s height or weight is much higher or lower than average.

Modern furniture manufacturers offer customers a wide range of chairs of various sizes.

In such cases, they turn to manufacturing specialists to calculate the parameters and obtain custom-made furniture with higher or lower legs, a wide seat, a certain angle of the backrest, and an increased distance between the armrests.

The standard model is considered to be with a total height of 750 mm.

DIY office chair repair: instructions with video

A modern office chair is a functional and comfortable piece of furniture, equipped with a rather complex mechanism that sooner or later fails. In such a situation, there are three options for the development of events: buy a new one, take it to a specialized workshop, or repair the office chair yourself.

As practice has shown, it is quite possible to do this work yourself. The only thing that is required from the master is strict adherence to the sequence of actions and implementation of the instructions that will be provided in this publication.

Choosing the right chair is a responsible event. Not only your convenience, but also your health depends on it. Sitting for many hours in an incorrect position is the most common cause of the development of scoliosis, osteochondrosis and all diseases associated with congestion in the body. If you do not dream of varicose veins and swelling, then do not neglect the correct placement of your feet on the floor.

What parameters are adjustable?

To adjust an office chair, you need to change or adjust its parameters:

1. The highest point of the seat should not reach knee level or be slightly lower. It is also adjustable according to the tabletop level. When a person sits with his hands on the table, his elbows should be bent at an angle of 90 degrees.
2. Backrest tilt. It should be fixed at an angle that provides the most comfortable position for the back of a sitting person. The chair should not rest against the spine or, on the contrary, lean back too far.
3. Oscillatory mechanism. This parameter is adjusted depending on the person’s weight. The larger it is, the tougher the swing must be so as not to fall.
4. The height and angle of the armrests should be such that the elbows of a person sitting in a bent position touch their surface. Otherwise, excessive pressure will be placed on the fingers and supporting parts of the hands.

To determine the correct body position in an office chair, you need to follow three simple rules. First, it's a good idea to position the center of your computer monitor directly at a person's eye level—you don't have to move your neck to read the information you need on the screen. Secondly, you need to feel good support for the curve of the lower back. Thirdly, the distance from the back of the shin to the front edge of the seat should not be more than 5 cm. To check this, just clench your fist and see how it passes freely between them. If your fist presses too hard or doesn’t fit at all, your back needs to be pushed forward. If the distance between the shins and the edge of the chair is too great, it is moved back.

Question 2. What sensations do you want to get?

Each chair is created with a specific idea, and we assure you that if it is chosen correctly, it can acquire the significance of a beloved family member and even replace a psychotherapist.

Dream

A lounge chair with a high back creates a feeling of relaxation, peace, trust; you want to doze off in them and gradually forget about the difficulties at work or in business. Models for dreamers relax and direct your gaze upward. As a rule, they have a significant backrest angle, very comfortable armrests and a headrest.

Take a break from everyone

Options with a high back and “ears” in the head area make it possible to isolate yourself from everyone for a while, feel isolated, hide and put your feelings in order. For anyone with a busy work schedule, they are essential (Lou Read by Driade).

Here you can choose a chair of any design and style from more than 1,000 items!

Select a chair

By the way, a fireplace chair with “ears” appeared in England, and was supposed to protect the ears of the sitter from harsh English drafts. Today there are many modern versions that look great in interiors. We recommend paying attention to Wanda (Galimberti Nino) or Capote (Mobilidea).

Note: When choosing a lounge chair, pay attention to the following nuances:

• if it is low, it is suitable for interiors where there will be no formal or semi-formal meetings. And one more thing: it is difficult for older people to get up from such a chair;
• very soft models are certainly good - you climb into them like a cloud, but they do not hold their shape. The pillows will need to be fluffed every time to keep the room looking neat. Think about whether you are ready for this;
• chairs without armrests force you to keep your hands on your knees and your elbows in the air. This makes it possible to be in good shape and not relax;
• The width of the armrests increases your personal zone - the wider the armrests, the larger and more significant you feel.

How to adjust the backrest

The height of the back of the chair provides support for the back and arches in the lower back. To adjust its position, you must first sit correctly. The above instructions should have already been completed. Changing the position of the back of an office chair without adjusting the height is useless: the fit will still be incorrect.

Once you have the correct position in the chair, you need to adjust the backrest so that it supports your back and does not create an excessive forward or backward lean. The position adjustment is carried out as follows:

• it is necessary to use the screw on the back of the chair to raise the backrest to the limit;
• then you need to sit on the chair and change the position of the screw until the backrest is in the correct position;
• If the product does not have an adjustment screw, you will need to use orthopedic products.

In addition to the height, the correct backrest angle must be set. Once the back of the office chair is at the desired height, you can adjust the angle using another screw. The tilt of the backrest is determined by the position you choose. While sitting in this position, you should feel like the chair is supporting you. Tilt adjustment is not available on all models.

How to choose office chairs

What we pay attention to:

• Frame. Must be strong enough to easily support the weight of a visitor of any size and serve for a long time regardless of the intensity of use. Chairs with a wooden frame are most often designed for a load of up to 100 kg; they fit perfectly into a business office environment, but are not strong enough. Models with a metal frame are better suited for the office.
• Upholstery. The material is chosen taking into account how intensively the chair will be used. If a large number of people come to the office, then it is necessary to select materials that are wear-resistant and resistant to mechanical damage. Durable but affordable furniture fabric or mesh is ideal. Chairs upholstered in genuine leather or eco-leather look more solid, but will not last long with frequent use, and in the hot season or in stuffy rooms it will not be very comfortable to sit on a leather chair.

Louis XV style

Furniture made in the style of the Sun King continues to be in great demand throughout the world. By choosing the Louis XV style you can get original and elegant office furniture.

Featuring a stylish backrest and floral mahogany fabric, the seating is ideal for adding coziness to the entire space. At the same time, the business principle in its interior will not suffer at all.

A Louis style chair is distinguished by several characteristic features:

• Curved solid wood frame;
• Two armrests;
• Bent file;
• Curly legs ending in snails
• Flower carving on frame

The Louis XV model has a curved frame, while the Louis XVI model has simpler and more straightforward shapes. It is also characterized by thin, pointed and grooved legs.

Napoleonic style chair

An armchair in the Empire style of the last century is a symbol of nobility and class. Indeed, installing a wooden Napoleon style chair with a swan collar in your office or living room can add a unique chic touch to the interior of the room.

On the modern market you can buy a chair in the Empire style, so popular in the Napoleonic era. There is nothing stopping you from covering it with other coatings to suit your taste or changing the shade of the wood. The same goes for all other furniture in the Empire style.

The Empire Chair often has the following characteristics:

1. Mahogany structure;
2. Swan armrests;
3. Velvet or satin fabrics;
4. Sculptures of swans, dolphins and eagles.
