How to Choose a Height Adjustable Chair?

For adults and children who spend a lot of time at a desk or desk, it is very important to stay productive. Height-adjustable chairs provide a comfortable and comfortable position.

Chairs with lifts can be used by both children and adults. The seating and back surfaces can be conventional or orthopedic to suit the shape of the body.

Orthopedic models can have the following configurations:

• Lumbar and hip bolsters;
• Armrests;
• Headrests (with a change in the angle of inclination);
• Footrests (front or circular) to improve blood circulation in the legs. They can also be foldable or stationary);
• With supports for the shins and knees (visually, such models do not look very comfortable, but they allow you to redistribute the load from the back to the legs);
• Vertically divided backrest (lightens the load on the spine).

Depending on the lifting or lowering mechanism, the following types are distinguished.

• With manual mode:
  • Screw Is the simplest option. You can change the height by simply rotating the seat: counterclockwise to raise and clockwise to lower. Practically not used, as there are more modern and convenient options.
  • Stepped - when the planes for sitting and back move along the base and are fixed with special clamps. Such mechanisms are usually equipped with children's desks, where the adjustment goes as the child grows.

• Semi-automatic (with gas lift) are systems in which the change in height is controlled by a lever. You need to click on it, and the mechanism will work.
• Automatic. In them, a piston exerts pressure on the gas cylinder built into the support. The gas compresses the springs and allows the seat to move. The smoothness of the movement depends on the shock absorber. It is better if it is metal rather than plastic.
• Transformers. Such a chair can be swivel, with an adjustable tilt and a change in the distance from the front edge of the seat to the back. They are suitable for all people who spend more than three hours a day at the computer.

The most natural, environmentally friendly and therefore suitable even for children's models is wood. It is better if harder tree species are used, so the product will be stronger. Plus, they have better texture. To prevent the wood from drying out and cracking, keep such a product away from heating appliances and sources of moisture. In addition, the wood requires special care and treatment.

Modern chairs are rarely made entirely of one material, as such models will be less durable. In addition, each material has its own processing characteristics. Usually, the frame is made of metal or plastic with a metal profile inside, less often - of plywood. It is better if the supports are also partially or completely metal. Metal and plastic are easy to clean and moisture resistant. The main thing is to pay attention to the thickness of the frame. In no case should he bend.

Depending on the amount of filler, the following types of chairs are distinguished:

• Soft;
• Semi-soft;
• Tough.

As a filler, both cheaper foam rubber or felt can be used, as well as more expensive polyurethane foam (it is more elastic, less punctured and deformed).

Different fabrics are used for upholstery:

• Textiles (microfiber, mesh fabric, acrylic, polyester). The fabrics are durable and breathable. They are most often used for children's models.
• Leather. Differs in high cost, resistant to deformation, wear and pollution.
• Artificial leather (vinyl). It is inferior to its natural counterpart, is less durable, does not allow air to pass through.

The average seat height for an adult is from 45 to 50 cm, the support surface of the backrest is at least 32 cm, and the width is at least 38 cm.

The transverse parameters of the seating plane can be as follows:

• Narrow - up to 50 cm;
• Medium - from 50 to 60 cm;
• Wide - from 60 cm.

Longitudinal parameters are as follows:

• Small - from 50 to 60 cm;
• Medium - from 60 to 70 cm;
• Deep - from 70 cm.

When setting the height of the seat for children, you can be guided by the following table:

The height of the child's back should be up to the middle of the shoulder blades. For teens, you can use the adult options. Naturally, you need to take into account that all people are individual, and the proportions of the body are different for everyone: someone has a longer torso, someone has legs. Therefore, you need to select furniture for long-term and constant use in accordance with your physique. It will be better to measure all parameters of a person in a sitting position before buying.

First of all, any furniture should be suitable for the interior of a room, study, office, institution. If the chair has already been purchased as a gift or provided by the employer, its color can be changed only by putting on a cover, changing the upholstery or painting with paints suitable for the material. If the selection process has not yet been completed, then it is worth thinking about how it will look.

The range of models and colors is truly huge. These can be both plain and colored options. But not all ideas can be realized in life, since a lot depends on materials. Wooden surfaces can be natural shades, painted or patinated. Their palette is somewhat limited. The metal can be painted or chrome-plated, with a shiny or matte surface, the color solution in this case is limited by the choice of paint.

Plastic is a more convenient material for processing and painting. Products from it can be of a variety of shapes, colors and textures. The greatest demand is for models that combine two or three colors.

Decorations can be both the main components of the chair and its additional ones, for example, a rug, if the model is on wheels, or a cover. The back can be of different shapes - oval, trapezoidal, rectangular or other arbitrary. The original shape, and even in a contrasting color, will not be suitable for ergonomic models, but will become a striking element of the interior. For a student, armrests are not needed, but if work is done on a computer, then they are simply necessary. The armrests can be of different shapes and can be attached to both the back and the seat.

The chair can have one support or two (depending on the height adjustment method). They can be in contrast with the rest of the parts or match in color. If there are a lot of shiny surfaces in the decor of the room, then the support can also be shiny. The cross (as a rule, with five rays) can also be of a contrasting color. Wooden models can be decorated with carved details, decorative overlays with fancifully curved supports.

Another decoration is the upholstery. It can be plain, with a pattern (for example, with the image of your favorite character from a cartoon or movie). The back can be fully upholstered in textiles with 3D animal details.

Regarding the chairs, adjustable in height, due to their design features, it is difficult to come up with some original solutions. However, new items never cease to amaze. If a model looks unusual, this does not mean that it is uncomfortable to sit on it. On the contrary, knee-supported chairs effectively relieve stress from the spine, and some original models can be used from birth to adolescence.A chair with an impressive complex mechanism will look great in an interior where the latest technical innovations are used. A bright, sleek, compact chair will take center stage in a modern interior. Bold options are suitable not only for the home, but also for defusing the atmosphere in the office.

Children's models differ significantly from adults.

When choosing them, you need to take into account several nuances:

• The first requirement for all children's furniture is strength, reliability of fasteners and safety of materials.
• For kids, a desk with a simple chair is suitable, while a student needs the most comfortable and multifunctional chair and table.
• The landing should be correct: between the thighs and the lower leg - a right angle, the feet are pressed to the floor, and the back - to the back. A younger student should not have armrests (elbows should lie on the table) and a headrest (so that the child does not sit sprawling).

• There is no need to equip a first grader's chair with complex mechanisms and rollers (swinging or spinning, the child will be distracted), this is an option for an older age.
• The upholstery must be breathable. Removable covers can be sewn or ordered to make cleaning easier.
• Of course, practicality is important in this matter, but seeing pleasant colors or patterns, the child will begin to complete the lessons with great pleasure.
• Despite his age, the child must also participate in the selection process. So the child will not only appreciate and take care of furniture more, but also feel his own importance.

Such chairs have become popular due to their advantages:

• The main advantage over ordinary chairs is that they can change their parameters and, therefore, are more comfortable;
• Growing models save money and time for choosing other models if the child has grown;
• Due to the variable height, a person of any height can be placed on such a chair;
• A chair fixed in different positions will allow you to sit at a table of different heights;
• Allows you to maintain and maintain health.

They are not without disadvantages:

• If the chair is designed for a certain load, people with a weight exceeding the maximum permissible cannot sit on it;
• Gas lift models should not be used at low temperatures. You need to determine the parameters while standing, and only then sit down and make sure that they are comfortable;
• Models with a stepped system allow you to increase the height by a certain step, which is less convenient than continuous increase.

When choosing a chair-"rastishka" or just a comfortable office chair, you can refer to the reviews of friends or read them on special sites. Several of the more popular manufacturers should be considered. Overall, the brand received good reviews "Bureaucrat"...
