Advantages of a height-adjustable table, design criteria
The table top of the desktop should be located at a level that corresponds to the growth of a person and the dimensions of his chair. The need to comply with this criterion is explained simply - with constant work in a sitting position, the correct posture is very important. The ideal solution in this case would be a table with adjustable height, the parameters of which are individually configured for a specific user. Such a piece of furniture will help to avoid excessive tension of the spine, normalize blood flow, which will positively affect work productivity and health.
Advantages and features of adjustable designs
An adjustable table is a special design that has a mechanism that changes its height. Thanks to the manual movement of the countertop or the presence of a special electric drive, a seemingly ordinary piece of furniture can be used in different positions - both sitting and standing. The advantages of this solution are obvious:
- Using a universal desktop, an office worker can alternate the positions of his body, because sitting, as you know, is harmful to health.
- The problem of incompatibility of the employee’s physique and table size is solved: due to high growth, a person has to stoop, and because of his low neck, he is constantly in a tense state.
This model is also ideal for children. With its help, many hours of homework will not affect the health of the children's spine. The height is adjusted to the height of the child, and a changing angle allows you to maintain an even posture. Also, the advantage of a desk with height adjustment is its versatility. Over time, the baby will begin to grow, but children's furniture does not have to be replaced with a new one - just adjust the countertop to suit the height of the student.
Varieties of adult models
The choice of adult models is quite extensive. Height-adjustable tables are suitable for both sitting and standing positions. But depending on the destination, such models may vary. The design for standing work provides high supports, a narrow countertop and minimal functionality. If the worker sits most of the time, the furniture will have slightly different dimensions and have more diverse functionality.
In addition, there are models to automate their adjustment. The table can be mechanical or with an electric lift. In the first case, the height of the structure is adjusted using the handle, and in the second - thanks to the electric drive.
Mechanical, in turn, can be represented in two varieties:
- Stepped. Such a mechanism involves changing the height of the table due to the displacement of the countertops in the grooves that were previously installed at different levels. You can also put plugs in the holes on both sides of the supports and thus change the length of the legs.
- Screw. This mechanism provides a different principle of action: the height of the table changes due to the circular rotations of the legs.
A table with a mechanical adjustment mechanism can be made with your own hands, which will significantly save on an expensive purchase.
Choosing the right model for your needs, you should also consider the presence of additional options. If they are not, and the design provides only a countertop with supports and an adjustment mechanism, such a table will cost much cheaper. If convenience is a priority, you should pay attention to improved options - with a height control panel and built-in sockets, which will allow you to connect a computer or other office equipment without pulling wires through the room.

- Writing. Such models often provide for the possibility of changing not only the height, but also the inclination of the countertop, which is very convenient for working with documents, but not suitable for installing a computer. The design usually has a mechanical adjustment mechanism.
- Computer. Its main feature is dimensions. The dimensions of the countertops often provide a place only for a laptop and mouse. The working surface can be folding and have moving elements: one half of the table is designed to install a computer, the second - for the seated hand, on which it will rest. Stationary structures do not provide for wide functionality and look like a standard table with a leg in the middle. Bedside models, in turn, are equipped with wheels for movement, a side support and a rotating axis. They are made in C or L-shape.
- Office models. Office tables changing their height are the most functional representatives of the line. They are equipped with all kinds of shelves, sockets, footrests and other additional elements that make the employee's work as comfortable as possible. However, budget options are often found - laconic tables with no frills.

Features of children's products with adjustments
The main feature of children's tables with variable height is that they perfectly adapt to the growth of the child. The control mechanism of this design can be:
- Electric. A table with an electric drive is more convenient to use, and if there is a control panel, the child himself will be able to adjust the height and inclination he needs. The only drawback is that such furniture is very expensive, so not every parent can afford it.
- Mechanical. Such a system for lifting the countertops is considered the simplest, therefore, the cost of the product will be quite low. Adjustment is carried out due to a special screw or a stepped mechanism - in one case or another, an adult must adjust the height.
Children's furniture is often equipped with a countertop, which is able to change not only the height, but also the degree of tilt. Unlike school desks, stationary located at a certain angle, such models can be adjusted for themselves. In addition, they have special compartments and shelves where you can place textbooks and notebooks, and a footrest.

The countertop is most often made of wood or its substitutes:
- Chipboard. The most cost-effective material. Disadvantage: a little fragile, which reduces its life.
- Fiberboard. More reliable, expensive material when compared with particleboard. Advantages: high resistance to damage, good moisture resistance.
- Array of wood. The most expensive, but also the strongest and most durable raw materials for the production of adjustable tables.
Sometimes metal is used to make adjustable tables. This is a heavy and reliable material with high resistance to damage, but it is used exclusively for furniture that will be used for industrial purposes. The table is made of strong and durable steel, which significantly increases the cost of production, or of aluminum, soft and less wear-resistant, but cheap counterpart. Legs in rare cases are made of wood, but solely for decorative purposes (as a coating), they will still be based on hard iron.

Corner models will help save space in a small apartment, use space effectively: furniture is simply moved to the corner of the room. This is the best solution for those who work at the computer. The second option is a standard rectangular table. It is universal for any specific activity, perfect for narrow rooms, and also allows you to organize a comfortable working area in the office. In addition, there are round design options - with their help you can beautifully equip a working corner in the living room or bedroom. Such a table often provides a convenient recess for the seated.

When working at the table, it is very important to be in the right position, because the state of the human body depends on this. If the position is incorrect, the blood flow is disturbed, a strong load is placed on the spine, which leads to its curvature. As a result, fatigue appears, disability decreases. That is why it is so important to customize the individual height of the countertops, taking into account the specifics of your activity:
- When writing. The back should be straight, slightly touching the back of the chair. If you deviate strongly backward, the increased load will fall on the neck, forward - on the spine. A small distance is necessarily provided between the table and the body of the seated person, the elbows should be completely on the surface (this will relieve tension from the hands). The legs in the fold should create an angle of ninety degrees, completely touching the floor.
- When working at a computer. Determining the optimal height is simple - just look at the center of the monitor: if the head is leaning down, the countertop needs to be raised, if the eyes are not looking straight, and up - lowered.
- When reading. The book should be at a distance of 35-45 centimeters from the eyes. Keep your head straight. Do not lean it back or tilt it forward strongly, so the load on the neck increases. Doctors recommend reading in a position at an angle of 135 degrees, while leaning back in the chair, blood circulation is not disturbed, and the spine does not feel discomfort.
It is better to avoid foot to foot position - it disrupts blood flow and leads to various diseases, including the development of varicose veins.
For people who spend a lot of time at the table, regardless of the type of activity, orthopedists recommend adhering to the Sit & Stand concept, that is, the alternation of a sitting and standing pose:
- In the first case, the vertical position of the back is optimal: the angle between the spine and the hip joint, knee and hip joints should be 90 degrees.
- In the second - the countertop should reach the waist or waist of a person. You need to bend your elbows, put them on the surface of the table: if they form an angle of 90 degrees - this is the optimal height, if not - it needs to be adjusted.
For an adult with a height of 170-185 cm, the optimal height of the table is an indicator of 70-80 cm. For short people below 160 cm, this parameter should be about 60 cm. For those above 190 cm, furniture is often made to order and reaches 85- 90 cm
The design with adjustable dimensions is optimal for children. Since the child’s body is constantly growing, the level of the countertop can be adjusted to its current height. It is important that the student is sitting straight, without bending the torso, and his head is slightly tilted forward. The legs should rest against the floor with the entire foot, bend at the right angle in the hip, knee and ankle joints. The back should rest on the back of a chair or chair, and the hips should occupy about 2/3 of the seat.

When choosing a table that changes the height of the countertop, some difficulties may arise, since there are a lot of models, and the needs of different customers differ. You need to start with the dimensions of the furniture. The selected design should occupy no more than 30% of the free space in the room, so the necessary measurements should be made in advance. In addition, other parameters are taken into account:
- Type of construction. You must immediately decide what the table should be: with a mechanical lifting system or electric lift, stationary or mobile.
- Product Material Wooden models are the best option, but a more modest table made of chipboard, fiberboard or MDF is quite suitable for the office.
- The number of legs. For a table with a sliding mechanism, it is better to choose an option with two or four legs. They provide good stability, evenly distribute the load on the supports. Also, this option is more durable.
It is imperative to clarify the range of table height adjustment. If the minimum size is a standard indicator, then the maximum level of lift for different manufacturers may vary.
An important selection criterion is the reliability of the adjustment mechanism. Firstly, you need to clarify the load capacity of the model. For children's furniture, the optimal indicator is 50 kg, for an ordinary office desk - 70-80 kg, for storage of heavy items (computers, books) on the surface of the furniture, more powerful structures should be considered. Secondly, you need to pay attention to the strength of the support and the material from which it is made. The mechanism that raises and lowers the countertop should work gently, smoothly.
