Orthopedic chair for a schoolchild: top 10 best models and selection criteria

Even the most intelligent and organized child can have a decline in academic performance if he does his homework at an uncomfortable desk and sits in an uncomfortable chair. And, of course, a student’s workplace means not only good grades, but also health. A schoolchild who takes unnatural poses because of an uncomfortable chair or table deteriorates his posture - the basis of the child’s health. Incorrect posture often causes curvature of the spine, osteochondrosis, and even provokes the appearance of intervertebral hernias.

The health and safety of a child depends not only on the correct choice of table and chair. Many events and situations await the student: adaptation to school, interaction with peers, first independent movements. To always know that your child is okay, track his location and listen to the sound around him, install the “Where are my kids” application from the AppStore or GooglePlay.

According to the observations of pediatricians, it is precisely first-graders whose posture deteriorates sharply, and the older the child becomes, the more difficult it is to correct the situation. And if you don’t have to choose furniture at school, then the right choice of table and chair for homework will certainly save the student from health problems in the future.

What is an orthopedic chair

Poor posture is one of the most common diseases among schoolchildren. The modern student spends half the day, and sometimes longer, in a sitting position at school and at home. And most often it sits incorrectly. Back in the 19th century, doctor Fyodor Erisman saw a connection between improper sitting at the table and the development of pathologies of the musculoskeletal system. Therefore, it is important to provide the child with the right chair during school.

An orthopedic chair is designed to solve the problem. It has a number of design features that ensure the correct position of the student at the table. Ultimately, this contributes to the formation of posture.

The chair has the following design features:

Height adjustment. When sitting, you must follow the rule: your legs are bent at the knees at a right angle, and your feet are on the floor. To fulfill this condition, the chair is adjusted to the child’s height using adjustment mechanisms. Or it is equipped with a special footrest.
Anatomical seat. A special recess in the seat will force the child to move as close to the back as possible and sit upright. The slightly beveled front edge does not put pressure on the blood arteries under the knees and ensures blood circulation in the lower extremities. The protrusion will support the fragile spine in its natural position. The child will be less tired even with prolonged exercise.
Anatomically shaped adjustable backrest. It creates proper back support, relieving tension.

Comfortable children's chair, adjustable in height - structure and features

Parents found the adjustable school chair for home practical. This device helps children maintain correct posture and maintain a healthy spine. Even after sitting on such chairs for a long time, the child’s back does not get tired.

Thanks to the ergonomic design, the legs are always in the correct position. Therefore, you can forget about discomfort and incorrect posture. The regulating mechanism can be special holes with a button that can be rearranged. As a result, the seat is pulled higher or lowered.

The backrest can be adjusted using a push valve behind or under the seat PHOTO: ekb.qp-partu.ru

If we talk about a chair with a soft seat, then the built-in pump, operating on a special lubricant, acts as a lifting structure. When adjusting, a certain pressure is created, which pushes the seat into the desired position.

Pros and cons of orthopedic chairs

To avoid purchasing new furniture every year as your child grows and grows, you can buy one ergonomic chair for a schoolchild. It is easy to adjust to the student's height. In addition, such a universal model has a number of advantages:

prevention of spinal diseases and vision problems;
normalization of blood circulation in the back;
adjusting the position of the legs and back;

creating a compact workplace that does not take up much space in the room;
easy adjustment and height change.

The device is not without its drawbacks. These include high cost. But you can’t buy health, and taking into account the fact that some models can last for years, the purchase becomes even more profitable than purchasing an ordinary chair.

Types of orthopedic chairs

Manufacturers offer a variety of models of orthopedic chairs. Each has design features, advantages and disadvantages.

Computer

The most affordable and popular model among parents is computer children's orthopedic chairs and armchairs. They come in the following types:

Standard. A model with a solid back, which is equipped with a mandatory inward bend in the lumbar region or an overhead bolster. Most often, this design is accompanied by a swing mode.
Double horizontal backrest . The frame tripod is equipped with 2 curved compartments located in a horizontal plane. One large one falls on the lumbar region, the small one is located at the level of the shoulder blades. A headrest may be present. All elements are attached movably and are adjustable in depth and height.

Corsetry. The back consists of two vertical parts, which are located close to each other with a slight gap. They cover the entire back, slightly bending around the body. They have an anatomical structure and are adjustable not only in height, but also in the angle of rotation on the central axis. An ideal solution for children who are at risk of stooping or have already developed it.

Knee orthopedic chair

This model is a leader in benefits for the spine. Conventionally, kneeling chairs can be divided into:

Stool. Complex supports located at an angle relative to the seat are equipped with special pads for the kneecaps. They prevent "slipping" down. The model provides for adjustment of elements according to several parameters and 2 methods of arrangement. Straight when the child sits upright, and inverted when the main emphasis is on the knees with the back up. You will have to get used to the second position. You won't be able to stand it for long - your legs will get tired. But, in this position the skeleton is maximally unloaded.
Chair. The design is the same, but additionally a movably fixed small backrest is provided. This variation is recommended for children with spinal problems. Healthy children do not need a backrest.

Dynamic. Original design. Essentially, this is a rocking chair with knee supports. Instead of corner stops, the chair is equipped with wide curved runners with pads. Suitable for active and easily excitable children. The rocking process will help you calm down. At the same time, you can add an element of play to your routine studying.

Saddle chair

A little about what other types of orthopedic chairs there are. Not very common in our country, but popular abroad, is the saddle chair. This model is not recommended for schoolchildren, but some teenagers claim that it is especially comfortable to sit on this model.

The design includes a stop, a stand and an inclined seat, reminiscent of a horse saddle. The back is missing. Sitting on such a chair, the child loses the ability to slouch. The way you sit involuntarily forces you to hold your back. Sitting on such a structure is not easy, so it will take several days of adaptation.

The saddle chair has the following advantages:

Over time, posture improves;
the design helps maintain muscles in ideal tone, the habit of slouching disappears;
minimal load on the lumbar region;

legs do not swell;
The model is recommended for preventive purposes against the occurrence of intervertebral hernias.

"Dancing" chair

One of the varieties of orthopedic chairs without a back. At the top of the cross and the rack with gas lift there is a round soft seat with the ability to adjust. The angle of inclination and intensity of swing changes. The model is also equipped with a movable hinge for rotation.

The chair is suitable for correcting posture and training the vestibular apparatus. The model is easily recognized by the spring that wraps around the stand. It is covered with a transparent casing. A slight push off causes the stool to swing up/down quite intensely. The “dancing” chair is suitable for a short warm-up of the limbs.

Growing chair

A type of chair with the ability to adjust the seat and footrest to suit the child’s height, due to the fact that the seat and footrest are adjustable up, down, forward and backward, the chair can be adjusted as comfortably as possible to the child’s height. Such chairs are usually designed for tabletops with a height of 60-80 cm. They can be equipped with soft seats and other accessories.

Structural features of height-adjustable chairs, depending on the type

Experts in the field of orthopedics believe that it is necessary to use a chair on the recommendation of a doctor, and if the child is initially healthy and the parents have not heard any advice from a specialist, then read the next section. It tells everything in detail about the design of popular product options.

Standard models of chairs for home, height-adjustable

Among the wide range there are options for chairs, which are divided into simple and “sophisticated”. These devices differ not only in price category, but also in external features.

Orthopedic chair with solid back

A model of a chair for a schoolchild's desk can have a solid back. As a rule, it is slightly larger than the area of the child's back. This design has a reliable fixation. A correctly adjusted backrest takes the anatomical shape of this part of the child’s body.

Orthopedic chair with a back divided into two parts

Models with a split back are considered attractive and structurally comfortable. They are suitable for those children who do not experience back and neck problems. This option provides a comfortable position in a chair and helps relax the back muscles without stooping the spine.

Orthopedic knee chair for schoolchildren

It is the kneeling chair that contributes to the formation of correct posture in childhood. Therefore, you need to choose it carefully, taking into account the design and design features. As a rule, parents try to take into account the physiological characteristics of the child’s body, weight and height. This makes it possible to correctly select the appropriate height option, regardless of the presence of various regulators.

It is a fairly convenient option. Suitable for short children PHOTO: klasstorg.ru

Balancing orthopedic chair

The right chair for a schoolchild is not necessarily one with a back, armrests and other auxiliary parts. It can be presented in the form of a rocking chair. This model is also considered orthopedic. It prevents curvature of the spine. However, if you choose a wooden model, you need to ensure the strength of the connections. They spill the beans from time to time.

Orthopedic chairs with saddle seat

A saddle chair is a good furniture option for both schoolchildren and teenagers. Its seat is shaped like a bicycle seat, which is why it was named so. The design is comfortable, the upholstery material does not slip and does not lose its color over time.

Some models are fully equipped, including an air back, headrest, and various stands PHOTO: dutch.alibaba.com

Custom designed children's orthopedic chairs

If a child has some health problems, for example, with the back, doctors recommend choosing special orthopedic devices. They are prescribed to help the child adapt to school and improve academic performance. Among individual models, they are usually distinguished.

Dynamic school chairs for home. They differ in that they do not have armrests or backrests. It is convenient to adjust such devices according to the method of installation on the floor. With this chair you can accurately determine the center of gravity. Often similar models are chosen for transforming tables.
Orthopedic chairs for schoolchildren “Standing-sitting”. Such options are more suitable for teenagers who have suffered serious spinal injuries. They will also be relevant for back diseases. The legs in such chairs remain almost straight, but the pelvis is securely placed in the seat.
A school chair with a footrest will be comfortable if height adjustment is not enough. Sitting with support eliminates back problems. Since in this position the back will be forced to remain straight.

Any orthopedic product, used as intended, helps the child push his spine to the correct formation.

On a note! All ortho-chairs have some mobility, this helps the body not to be constantly in static tension. Accordingly, the risk of deformation of a child’s fragile back is minimized.

How to choose an orthopedic chair

When buying a chair with an orthopedic effect, you cannot focus only on the appearance and manufacturer. The correct approach involves taking into account many criteria. And they need to be considered as a whole:

Availability of a backrest. A model of a chair without this detail is not very convenient for a student, because in this case you will have to constantly maintain balance, and this is not very easy. In addition, not every schoolchild already has a developed vestibular apparatus, and sitting on a chair without a backrest will negatively affect his well-being.
Availability of a footrest. The legs should not hang down; they need support at such a height that the knees form a right angle.
Full adjustment of all elements. The chair should be adjustable in terms of seat and back height. The backrest itself must also be adjusted to the desired angle of inclination.
Rocking mechanism. It is difficult for children to sit in one position for a long time, and they use every opportunity to change positions and rock in a chair. It would be more practical to purchase a model with a swing mechanism. Then the child will be able to swing, and you will not worry that the chair will break.
Weight. The chair should be heavy enough to achieve maximum stability. But you shouldn’t buy an overly massive model that will be difficult for your child to move.
Safety. The model should not contain sharp elements. the material from which the chair is made must be environmentally friendly. The release of a strong odor, which indicates the presence of harmful substances, is not permissible.
Correct filling and upholstery material. As a filler, doctors recommend choosing latex, which demonstrates the maximum orthopedic effect. In terms of upholstery material, you should pay attention to natural or artificial leather. Textiles with a dense texture with an additional removable cover are also good: this will make caring for the product easier.

Armrests. Orthopedists do not recommend using them, since children tend to lean on one hand, and this minimizes the orthopedic effect. Armrests should only be used by schoolchildren who have a history of chondrosis or problems with blood circulation in the arms. When choosing such a model, give preference to models with armrests that are slightly inclined and long enough. Before purchasing, ask your child to place his hands on the armrests; they should reach the base of his palm. Ideally, the armrests should be removable. If you notice that the child does not periodically, but constantly leans on them during classes, it is better to remove the part from the chair.
Additional elements. For a more comfortable position, you can purchase models that come with additional pads on the back. They come in different rigidities and have an orthopedic effect on all parts of the spine. For children of primary school age, it is necessary to choose softer ones; it is advisable that the model supports the entire back, and not just the lumbar part. Manufacturers also produce orthopedic meshes for the back, which serve as a posture corrector.
Strength. The chair must be reliable and durable. Children are very active and love to swing and ride, so stability is an important factor. To do this, the model must have at least 5 wheels.

Before buying orthopedic chairs, you should definitely read the reviews of the owners. They often indicate how quickly the child got used to the model, as well as nuances regarding design features.

Important! Do not buy an orthopedic chair without a child. It is extremely important that the model goes through the “trying on” process for comfort. If a child cannot sit in a chair and experiences discomfort, it will be of no use, and the student will find more comfortable furniture. If your child has already been diagnosed with spinal diseases, you should consult a doctor to choose a model.

Mechanism: which one to choose?

Due to its functional features, the chair cannot be completely wooden: its frame is made of metal (cast aluminum, steel). The seat and back are made of wood, plywood, foam rubber or other durable material, and then covered with fabric.

Advice: it is more advisable to choose designs with a soft front edge of the seat, rounded downwards. When a teenager or younger child sits on such a chair, his muscles are not tense. However, you shouldn’t take ones that are too soft either - they relax the spine, which is unacceptable when developing posture.

The adjusting mechanism ensures a stable position of the seated legs due to the correct correlation of the length of the lower leg with the height of the seat. The child's thigh is touching the seat, but the back of the leg closer to the knee joint is not tense.

There are several mechanisms that change the height of a study chair. One of them is called gas lift , or gas shock absorber. It is located between the wheels and the seat, and is a long metal tube covered with plastic.

Operating principle of a gas shock absorber:

There is a cylinder inside the metal case;
the cylinder contains a valve with a kinematic spring and a piston;
there are two reservoirs on either side of the valve;
when the position changes between these reservoirs, the passage opens;
if the seat needs to be raised, then gas begins to flow from the first chamber to the second, if it needs to be lowered, then vice versa.

There are four quality categories for gas shock absorbers - the fourth is considered the most reliable. Information about gas lift is indicated in the accompanying documentation for the furniture.

Review of manufacturers

Furniture for schoolchildren should be of the highest quality and designed to suit the anatomical characteristics of the child’s body. The modern market is diverse, but not all manufacturers can boast of a combination of these parameters. When choosing a chair, you should pay attention to the products of time-tested and user-tested factories:

Mealux is a Taiwanese manufacturer of upholstered furniture with height-adjustable backrests and seats. The chairs from the company are comfortable, practical, durable.
Moll is also a German manufacturer of exceptionally high-quality furniture. The chairs are made from environmentally friendly materials and provide a comfortable position for the child combined with correct posture.

Kettler is a company from Germany. Produces high-quality chairs with orthopedic functions and ergonomic shapes. The company's models are equipped with adjustment capabilities and removable covers.
Paidi is a German company that produces “growing” chairs. The models are easily adjusted to the child's parameters. Options are offered for children of different sizes.

Furniture from these companies is an excellent option for maintaining the health of a schoolchild. The furniture will contribute to the formation of correct posture of the child, provide comfort and last for many years.

TetChair Kiddy

Bright and stylish retro model. The reliability and stability of the chair is ensured by a crosspiece attached to a metal rim. It has 6 wheels, providing the model with maximum mobility.

The chair has an interesting back: not soft, like other models, but plastic with holes located all over the surface. Permitted load weight – up to 100 kg. The model is made of high-quality, safe materials.

Nowy Style Ministyle

A distinctive feature of this model is the bright prints on the upholstery, which will especially appeal to younger students. There are girlish and boyish drawings. You can also choose plain upholstery in bright or calm colors.

The back and seat of the chair are soft. They have an ergonomic anatomical shape. There are no armrests in the model; the manufacturer motivates their absence by the desire to instill in the student the correct sitting position on the chair. The backrest moves up and forward, which allows you to find its most successful and comfortable position.

When purchasing, it is important to pay attention to the type of rollers. The manufacturer offers options for soft carpets and smooth surfaces. The permitted load on the chair is up to 80 kg.

FUNDESK SST6

Model from a company specializing in the production of children's furniture. Prices for products are above average, but this is justified by high technology, a variety of adjustments and high-quality materials.

The chair has a double vertical backrest in the shape of petals, adjustable in height and angle of inclination. There is a footrest under the seat. But users note that it is extremely inconvenient. The roller base is equipped with a gas lift system and mounted on rubberized wheels. Thanks to this, the loaded chair remains motionless.

MEALUX Aladdin

An interesting model with the name of a fairy-tale hero. When looking at this chair from the side, you get the feeling that it is all moving in waves: a backrest concave with wings, a seat with height differences. According to the manufacturer, this promotes maximum unloading of the spine.

The backrest is adjustable in height separately from the seat, which in turn can change its position in depth. The base with a gas lift system is equipped with nylon-coated wheels. This allows you to protect the floor covering and slow down the chair when moving.

Chairman 696

Compact budget model of fairly good quality. Designed for loads up to 100 kg. The seat is soft, the back is concave inward, and is made of mesh metal-plastic. The backrest can be adjusted. The model has armrests, but they are a little hard. The crosspiece is plastic, with wheels and a gas lift system, very strong and durable.

Bureaucrat KD-2

The chair looks compact, although at first glance the unusual shape of its base is confusing: the crosspiece on wheels is not under the seat, but extends far forward. The height of the seat and the depth of the backrest are adjusted by separate mechanisms. The setting is fixed and is performed by moving it into special grooves. The seat moves up and down and back and forth on the platform, but this does not affect the comfort of sitting.

The dimensions of the chair are quite large. The manufacturer justifies this fact with a reinforced design. The back is rigid and slightly curved forward to support the lower back. Inside, the soft parts are filled with molded polyurethane foam. Formally it is plastic, but it looks and feels like elastic foam. The permissible load on the chair is 100 kg.

RIFFORMA Comfort-33

Model of the “growing” chair type. Suitable for children from 3 to 13 – 14 years old. Permissible load – up to 110 kg. The height of the seated person is from 100 to 175 cm. The model does not have a footrest, since its design is such that the seat can be lowered as low as possible, almost to the floor. There is a special recess for the legs at the base in the crosspiece, so they will not be left without support in any case.

The back and seat have a special relief that is beneficial for posture. The wheels are blocked. All elements of the chair are slightly rounded, which is important for safety.

The model is affordable. Its only drawback is that the seat fixation is not rigid enough: it tends to tilt forward if the body position is incorrect.

Moll Maximo

Model of a high price category made in Germany. It is distinguished by a variety of upholstery shades, which allows you to choose an option for any interior, taking into account the tastes of the child. The tone of the plastic can be matched to your desk or table.

The chair is intended for children from 3 years to middle school age. The base is steel, five-beam, on wheels with locks. There is no footrest; you will have to purchase it separately if necessary.

The seats and backrest are adjustable and anatomically shaped. To ensure that the design continues to control posture when tilted to the side, the backrest is slightly curved at the edges. It is possible to adjust the seat depth. The rollers can be replaced with static ones, but they will have to be purchased separately.

Comf-Pro Ultraback

Ergonomically efficient design: the perforated back provides a smooth fit to the spine with constant support in the correct position. The chair is equipped with a flexible height adjuster, which allows you to adjust it to the child. The position of the backrest is fixed with a rigid screw, which ensures its immobility. Separate adjustments are provided for depth with rigidity, making adjustment as flexible as possible.

Adjustable seat height makes the model comfortable even for preschool children. The seat depth can also be changed using a special lever. The crosspiece has the most stable structure and prevents tipping over.

Kulik System Fly

Kim A premium model with a futuristic design: it's a cross between a spaceship seat and a racing car. The design is highly ergonomic. There is a headrest, a protruding part of the backrest in the lumbar area, and anatomical recesses on the seat. The base is a metal cross with a gas lift system and a footrest. The upholstery combines eco-leather and textiles in contrasting shades.

The back and seat are filled with elastomer that retains its shape well. This filling is often used in business class furniture. Buyers of the chair note that its high quality is maintained even after many years of use. The parts do not become loose or squeak.

Desk for schoolchildren

A table is perhaps the main component of a student’s workspace. There are a variety of desks sold in stores: large and small, expensive and budget, with and without additional compartments and shelves. All you have to do is choose the table that suits your child.

Table or desk

Having a desk in front of a table has one significant advantage: the tabletop of the desk can be positioned at an angle - this position is good for posture. But there are also disadvantages: the desk can only be used for homework (installing a computer, doing complex crafts, or doing professional drawing on the desk will not work due to lack of space), and not every child will like the desk at home as a constant reminder of school.

A good option is to use the desk while the child goes to primary school. And when the student moves to fifth grade, the desk can be replaced with an “adult” desk.

How to choose the right desk for a schoolchild: basic criteria

The main criteria for a suitable desk for a schoolchild:

Ideally, the width of the tabletop should be at least one meter , but if the room is small, you can get by with more compact furniture. The minimum tabletop size sufficient for textbooks, workbooks, stationery and other student supplies to fit while completing an assignment in one subject is 60*60 centimeters .
The height of the table should correspond to the height of the child - a tabletop that is too high or too low will certainly ruin the student’s posture. A simple way to check if the table is the right height is to “try it on”: ask the child to put his elbows on the table and stretch his arms up, the fingertips from this position should freely reach his temples.
Environmental friendliness - now desks are made from a variety of materials that are harmless to human health. Previously, only wood was classified as environmentally friendly materials, but thanks to modern technologies, furniture made from chipboard (chipboard), MDF (fine wood fraction), and even plastic is not inferior to wood in terms of health safety, and is cheaper.

The presence of additional drawers and compartments in the table is optional. It is better to consult with your child: perhaps it will be convenient for him to store student supplies in the desk cabinets, or perhaps on separate shelves (for example, on a rack).

Types of desks for schoolchildren: advantages, disadvantages, average prices

The table below shows the best and most popular types of tables for schoolchildren: their pros, cons and average prices.

More details about each type of desk for schoolchildren:

Classic tables with rectangular tops

Simple models that are found in almost every home. When buying a classic table for home, you can save money due to the low cost of the models, but you will have to carefully select the height to suit the child’s height - usually classic tables are not adjustable. For the same reason - the inability to adjust the height of the furniture - the classic model will only suffice until the child grows out of it.

Corner tables

Photo: ekb.rosfirm.ru

A good option for small spaces. If necessary, the corner table can be easily divided into different zones: for example, for two children, or into separate areas for lessons and relaxation.

Desks

Desks are well suited for primary school students: they help to develop good posture and hold your hand correctly when writing. Typically tables and desks are height adjustable.

Transformable tables

Photo: parta-plus.ru

Adjustable in height, depth and width to the desired size from the first grade until the end of school. Typically, transforming tables are designed for heights from 110 to 200 centimeters. Some models also provide adjustable tabletop tilt.

Schoolchild's corner

Photo: bogdanovich.miruyuta96.ru

A convenient option for furnishing a children's room from scratch. All furnishings will be designed in the same style, and you will not have to buy additional shelves or bedside tables. You can choose a corner with the necessary additional elements (for example, for installing a laptop or desktop computer, or with a separate space for drawing), but the price of school corners is high.

Correct chair adjustment

When using an orthopedic chair, it is important to correctly adjust it to the child’s body type. According to orthopedic doctors, sitting on a chair at a table should be like this:

The legs stand on the floor or a stand with the entire foot. The thigh and shin form a right angle.
The back is straightened and leaned tightly against the back, parallel to it.
The elbows lie on the table, also forming a right angle.

To check if the child is sitting correctly, place your hand between the edge of the table and the student's solar plexus. If the palm passes freely, the position is correct. The depth of the seat is checked by the ability to lean on the back without changing the position of the buttocks. It should be 2/3 of the length of the femur.

Parent Questions

Tell me, is it possible to use a chair for a non-standard table with an increased height?

The growing chair is perfect for a table from 65 to 80 cm. It is designed to fit standard desks and dining tables.

The child is already accustomed to sitting hunched over. Will an orthopedic chair help him?

Will help. The back of the chair constantly exerts uniform pressure forward on the lower back and, with prolonged use, straightens and the head and neck move back to the physiologically correct position. It is extremely important to teach your child to sit correctly on an orthopedic chair, which helps relieve the load on the spine. The entire surface of the back must be pressed tightly against the back.

We bought an orthopedic chair for a first-grader and set it up. They set it up in the store, and he said it was convenient. But on the second day he refused to sit on it. What to do?

An orthopedic chair takes some getting used to. Try to motivate your child to sit on it in some way. Gradually he will adapt and the chair will become comfortable for him.

The child asks to put a pillow on the chair. Maybe buy an orthopedic one?

Not worth it. The orthopedic pillow is designed for regular chairs. In orthopedic surgery it will be superfluous and can negate its entire therapeutic and preventive effect.

The child has scoliosis. What parameters should a chair have?

High anatomical back, seat with adjustable tilt and adjustable height, wheels must be locked.
