Salli concept
Salli Systems is the leading developer in sitting health and avoiding sitting disorders (SD). Our innovative work and effective development since 1990 have taken us furthest on the way towards understanding how to attain good sitting health.
Salli Concept is a profound sitting welfare program
It is based on science and medicine. It consists of all the parts of sitting physiology that are needed to gain stable health in sedentary jobs.

  • Be aware of the potential and possibilities of high-quality sitting environment
  • Use two-part swing-models, the seat of which adapts to your movements, e-table, helpful accessories and high-quality height-adjustable monitors.
  • Be motivated and learn to adjust and use the furniture in the optimum way
  • Use sitting- and circulation-friendly clothing that does not press your soft tissues and disturb circulation
  • Exercise often enough to boost the brain, energy and circulation: Stand & Stretch, Sit & Swing, Roll & Reach, Walk & Talk, Work & Gym (have some exercise equipment near to where you work) 
By adopting all this you will avoid sitting disorders and most MSD, such as back pains, fatigue, and poor posture. You will stay healthier and be much more energetic and productive.



Future office
The office of the future includes all the current know-how regarding employee wellbeing, productivity and energizing factors. In the future the smart ergonomics- and health-conscious super offices increase productivity 1,5-3 times higher than it is in the traditional office. The healthy lunch and daily supplements provided by the company cut out even more of the unnecessary sick leaves. The additional cost for the future super office is very little when compared to the huge increase in productivity and profitability of the employees.

The interior is updated with new colours and decoration whenever the occupant of the room changes
There will still be need for separate offices for those who are doing demanding jobs and require concentration. On the other hand, the "Nest-Office" -type solution, where a large space is separated into smaller 4–6 m² soundproof spaces that open to the centre of the room (glass doors), will become more common as it is space-efficient, but allows working in peace. In the middle of the shared space there needs to be an adjustable elliptical conference table and in the corners space for excercise, breaks and snack stations.
Desktop computers will continue to be used because the smaller portable devices do not offer high-quality display and keyboard ergonomics. In addition, the desktop computer with its personalized artificial intelligence applications includes speech recognition, provides exercise and break tips, has sensors to track the health markers of the body and reacts to them, adjusts the wellness technology of the room, and performs automatically, or with voice control, a large number of the traditional tasks of an assistant.
In addition to the automatic and optimized monitor and table height-adjustments for typing and reading, automatic stand-by detection is also included. Table/elbow pads and (3) monitors are therefore always at the right height for good back–neck posture and hand ergonomics.

Ways to encourage movement
A good posture is the basis for wellbeing, health and working efficiency and it can be ensured by sitting on a swinging saddle chair with a gap in the middle, and standing for short periods (10–30% of working time), but no more than 20 min at a time. This way the upper body "stands" the whole time and the middle gap of the chair eliminates the harmful effects on the genitals, pelvic floor and inner pelvis.
Excercise can be encouraged by giving the employees the right kind of clothing and training for healthy lifestyle, by the employer's support (e.g. providing bluetooth device, or allowing swimming or exercise time during work hours), computer-generated tips that are based on one’s metabolic condition, exercise equipment, and sometimes also by common exercises or organized classes. The different excersice methods have descriptive names, such as Sit & Swing, Roll & Reach, Walk & Talk, Work & Gym.
Stretching mats, hanging bars, powerboards, bean bags, gym balls, back stretching boards, and other equipment are available for immediate use, in the workspace or the common space, when the immobility begins to make one stiff and reduce brain activity.
Sitting-friendly and comfortable clothes
Employees use the company's support to always wear completely pressure-free and airy clothes. There will no longer be harmful pressure marks in the legs (from socks and shoes), buttocks, thighs, chest (underwear) or waist (belt, trouser collar). The disadvantages of tight garments are recognized and rejected because they damage one’s appearance (cellulite, varicose veins, swelling), are uncomfortable and unhealthy, and make one tired. Sustainable, healthy, chemical free, organic clothing of natural fiber is promoted.
Bacteria, plants, lights and sounds help

In the office there is a large (100–200 l) growing box for air-purifying and beautiful plants. It increases productivity and also produces earth bacteria that improves mood and intelligence functions.
Reflexological stimulation of the soles can be done by rubbing one’s feet against the massaging chair base, or by stepping in a gravel box on the floor. This allows the energy flow to rise rapidly.
The numerous lights in the workspace are automatically optimized for both power and colour, depending on the season and time of day.
Quiet, soothing, user-friendly or relaxing music is played automatically or by request. Everyone has a high-quality headset.
Workspaces are customized for each employee with carpets, curtains, large wall images or decorations, to be fun and energy-efficient, so everybody will immediately be in a good mood when entering the workspace.
In the workspace or in the vicinity there are fiber-rich snacks that include healthy fats (seeds, nuts, avocados, organic fruit, etc.) to prevent the decrease of blood sugar levels and hence the working efficiency.
Organic green tea and bulletproof coffee are available the whole day as an excellent source for health and refreshment.

Sitting health
Many of us are not strangers to back, neck and shoulder pains. According to some statistics, as much as 80 percent of people suffer from some kind of back problems at some point in their lives. Many of us spend even 13 hours sitting every working day, and naturally the proper sitting position and the work chair play a major role in how we feel. Correct sitting has multiple effects on our wellbeing.

Wellbeing
The ergonomically designed seat of the Salli Saddle Chair directs your body automatically in the natural, health-promoting posture. Once you have achieved this, it is easy to work all day.
Energy
An upright and healthy sitting position affects the energy levels of your mind and body. As a result of the good posture, the rib cage can expand freely, which deepens your breathing. Improved blood circulation reduces headaches. On the active seat, the muscles in your back and abdomen get a little workout during the day.
Relaxation
On the Salli Saddle Chair, your body weight rests on the sitting bones. The lower back can therefore form a natural curve. The riding-like sitting position lets your back enjoy good posture without unnecessary muscle tension. As the load on the spine eases, the muscles in the neck and shoulder area can relax. The lower body forms a golden triangle: you are sitting on your sitting bones with your legs obliquely forward.

Healthcare
Ergonomic and healthy sitting position is best achieved on an anatomically designed, two-part saddle chair. Sitting on Salli automatically creates lordosis in the lower back, which relieves the harmful pressure on the disks. The gap in the seat makes it possible to maintain the good posture even during long operations, because there is no uncomfortable pressure in the genital area – and thus no need to round the back. 
When sitting on a saddle chair the body can move almost as freely as when working in a standing position. Moving around the patient and reaching for things is effortless. Furthermore, there is no need for a separate working chair in front of the table, because moving on Salli is so fast and easy. Salli accessories improve ergonomics in operating theatre, ultrasound and when taking samples.

Salli Expert has a two-part seat which enables you to maintain the good position even during long operations. Height control both by hand lever and by foot.
Foot Height Control enables you to adjust the height hygienically, without touching the lever by hand.

Dental care
In dental care the sitting position is the greatest health risk, because during long operations the position is unnatural and involves a lot of repetitive movements. Sitting in a bad position puts twice as much strain on the spine as standing.
Dentists often retire early because of various problems in their shoulders, neck and lower back. Almost everybody working in dentistry is affected by poor circulation in the lower extremities, shortage of oxygen, problems in hip, knee and shoulder joints, or genital health problems.
On a two-part saddle chair the back is in the same position as when standing, and the lower back lordosis can be maintained. That is not the case on one-part saddle chairs because there is a lot of pressure on the genital area and that makes you round your back. That position is a tremendous health risk for the disks and vertebrae in the lower back.

Salli started to develop in Finland ergonomic chairs based on the horse saddle. It intends to support sitting bones (hip bones) only and take pressure away from soft tissues. Thus, Salli is the only chair that allows you to sit with great posture as if standing, but as comfortable as when sitting .
Your position on Salli is the same of most sports: ready position. In this base position whatever movement is done, the body will activate core muscles. This will help to protect your lower back during the day and also, help to improve every arm movement, releasing tension from shoulder and neck.
Salli is the healthiest option when sit for long periods of time.

10 health effects
download.php
The following observations describe impacts that are achieved only by sitting on an active, two-part saddle chair. Sitting on the traditional one-part saddle chair contains so many serious problems in connection with posture, genital health and also with the health of the inner pelvic organs that it cannot be recommended as a working chair. 
Riding-like sitting is fundamentally different from the traditional sitting. The change affects positively the whole body, circulation and metabolism. Minimizing the disturbances in metabolism and eliminating health risks are the major goals of ergonomics.
The most essential positive effects of riding-like sitting are focused on the spine, all the way from lower back to the cervical vertebrae. Riding-like sitting affects posture, circulation into the lower limbs, genitalia, external and internal pelvic organs, muscles and joints, bowel movement, breathing, circulation into the head, and the alertness of the brain and the eyes.
Riding-like sitting makes it possible to improve vital functions by exercising, reaching from the chair and tilting the seat. These movements make sitting more active and improve work conditions.
When people start improving their sitting radically, the effort alone brings about a change in them. New kind of sitting makes people more conscious of their circulation, muscle tensions, back health, posture, metabolism and sitting position, and makes them want to improve their sitting environment further.
Aesthetical factors

It is justifiable to say that also your looks improve with the correct use of a saddle chair. Improved circulation in lower extremities is expected to decrease swelling, and the development of cellulite and varicose veins.  In addition, the improvement in the posture makes the upper body look better as the shoulders straighten and the neck and the head are held up. 

Back
download.php
Traditional sitting on a chair with 90° degree angles in hips and knees inevitably makes people slouch. When sitting on a saddle chair the thighs are in a 90° degree angle in relation to each other and pointing downwards in an approximately 45° degree angle. The pelvis is tilting forward, not backward, like in traditional sitting. In other words, on a saddle chair the pelvis is in a "standing” posture and thus we achieve the healthy posture on the back almost automatically. The lumbar vertebrae are in their natural position and the lower back forms a correct curve, lordosis. This posture can only be maintained on a two-part saddle chair that does not press the genital area and thus allows tilting the pelvis forward comfortably.  
This position of the lumbar vertebrae prevents deteriorative damage to the lower back and in most cases quickly decreases pain in the typical lower back/disk problems. In addition, the circulation in the lower back is improved, since the improved posture relieves muscle tension and especially improves the activeness in numerous back muscles. The increased circulation, in turn, increases the oxygen and nutrient contents in the muscles, the absence of which is probably the main cause for the common degeneration syndrome of the lower back.
Since the disks and ligaments have no blood circulation of their own (circulation is also very weak in the vertebrae), it is essential for the lower back to have good circulation so that the tissues can get sufficient amount of nutrients and oxygen and remove wastes. In a physically active back, or in a good posture, this metabolism works well. The arteries of the lower back are surprisingly small and require good muscle activity and relaxation to bring enough blood to prevent degeneration of tissues.
Sitting in a good posture on a saddle chair makes it possible to use the whole body in an effortless and natural way, giving the muscles of the lower back exercise-like movement. The upper body moves, when the chair is rolled from one place to another or reaching movements are made. We call this activity "Roll and Reach”, and it is very helpful in reducing dangerous inactivity during sitting.
Moving with the chair or reaching for things is easy and risk-free, as the feet rest firmly on the floor and the back is able to maintain the good posture with the help of the support from the legs. Correct use of back muscles leads to a gradual improvement in posture and prevents ailments caused by scoliosis.
When sitting upright on a saddle chair, also the sciatic nerve pains become less frequent as the deterioration of the lower back slows down. Typically the sciatic nerve is irritated (and causes pain) when the nerve canal becomes too contracted as a result of the flattening of the disk. The nerve canal can become congested also after changes in the bone structure resulting from lower back deterioration.
Swing mechanism in the two-part saddle chair makes it considerably easier to reach for things, and it also increases circulation (also lymphatic circulation) and muscle activity mainly in the lower back and pelvic area. The users tend to create movement also unnoticed when the body "asks for” activation. Such unconscious movements are swinging the pelvis, smaller or bigger exercise movements and rolling and reaching too.

Brain circulation

Up to 25 % of the total circulation goes into the head. The vessels are in a narrow space between the neck vertebrae, throat and outer neck muscles (mainly a muscle called Sternocleidomastoides). All static poor postures of the head or the neck make muscles tense and reduce circulation in the main vessels. The main vein (Jugularis Interna) is actually leaning to Sternocleidomastoides. If the muscle is tense, the circulation slows down, the blood pressure in the brain increases and headache easily follows. Good posture of the neck can be attained only when the whole back is in a good posture. Soft elbow pads close to the body help the shoulder area muscles to relax. The two-part saddle seat enables a good posture and prevents the aforementioned problems.
Using a high-quality saddle chair will increase the oxygen intake considerably. Stiffness and joint locks in the chest, ribs and the upper back decrease. This, combined with reduced muscle tensions and better posture, will make the whole breathing mechanism work better and allow the chest to expand fluently and the breathing to become deeper. Improved oxygen intake will increase the oxygen levels in the whole body and slow down the process of getting tired.

Circulation

There is about 4 litres of blood in the human body, and about 3–4 times that much lymphatic liquid that collects the wastes and pathogens from the body and transfers them to the blood vessels in the 600–700 lymph nodes of the body. The artery circulation is only 25 % of the blood, about one litre.
All other liquids are in the low pressure systems which are easily and usually disturbed by immobility, conventional sitting with its large pressure areas in thighs and pelvic area, tense back and shoulder muscles, and pressure in the stomach due to slouching and tight clothing. Sitting on a two-part saddle chair, and especially on an active seat, and wearing loose clothes can help to keep circulation and metabolism on a much healthier level.

Genital area

Roughly 50 % of the adult population in Europe suffers from some kind of physical sexual disorder at least periodically, and the numbers are rapidly rising. We sit on top of our private parts, and that is why it’s logical that sitting has a major impact on the circulation, nerve functions and metabolism of our genitalia. 
Men have a tendency to sit with their pelvis tilted backwards. This is an unconscious way of relieving the pressure on the root of penis on the pubic bone, where the nerves and the vessels leading to the genitals are located. When using a two-part saddle chair the lower part of the penis (of which about 9 cm is on top of the pubic bone, below the pelvis, behind the testicles) is not subjected to the same kind of pressure as when using one-part saddle chairs. The harmful compression of the pudendal nerve and vessels can be eliminated almost fully. When the sitting pressure in on the sitting bones (Ischial Tuberosities) the important lymphatic circulation works better.
Men also keep their thighs spread in order to eliminate the feeling of pressure on their testicles; trousers and their middle seam tighten up when men are sitting. In addition, tight clothes keep the testicles too close to the warm body. Sperm production is very sensitive to the rising of the testicular temperature. The two-part saddle chair cools down the testicles to their optimum temperature of 33°C (approx. 91°F). In conventional sitting the temperature of the testicles can often rise to 37°C (approx. 99°F). This is one reason behind the reduced quality of sperm.
For male cyclist the violent pressure on the tissues next to the pubic bone has been proved to cause impotence and testicular cancer. The same phenomenon has also started to occur among men using one-part saddle chairs.
Cycling has also been discovered to cause damage to the female outer genitalia, leading to decrease of sensitivity. Riders and users of one-part saddle chair can experience the same phenomenon.
Tight clothing and long-term sitting with reduced circulation, combined with the use of panty liners and sanitary pads, increase the risk of infections in women's genitalia. Sitting on a two-part saddle chair decreases this risk. Most women find an inadequate gap, or a saddle chair without a gap, uncomfortable around the pubic bone area because nerves and blood vessels get pressed between the seat and the pubic bone. This kind of pressure leads to reduced circulation, which is a health risk in itself.
A gap in the chair encourages both men and women to tilt their pelvis forward without the uncomfortable pressure against the pubic bone and the genitals. This helps to keep the lumbar posture in the natural lordosis, which is the ideal form of the spine. The two-part saddle chair eases the pressure on the genitals and preserves a safe angle between the thighs and the upper body.

Increased mobility

Traditionally, many jobs involve standing for the whole day. Working on a saddle chair is a great ergonomic alternative to standing. When sitting on a saddle chair, the employee is approximately at the same height as the standing customer. Less strain on the lower back and the increased circulation in the lower extremities help the employee to stay in a good mood and maintain the high quality of customer service.
By using a saddle chair equipped with wheels, the employee is able to move around effortlessly with just a small push from the legs that are freely positioned on both sides. If the task requires standing up repeatedly, it is also much easier to sit down and stand up from a saddle chair than a conventional office chair.

Intestine and pelvic area
download.php
As the upper body posture improves, the pressure on the stomach, small intestine and colon decreases and the stomach is no longer pressed between the pelvis and the chest. The increased muscle activity in the stomach area also increases intestine activity. All this has a positive effect on the bowel movements (peristalsis and its efficiency) and intestine health. In our modern lifestyle the intestine health is weakened also by too little of muscle activity. One-part chairs (traditional or saddle) also press the anus and rectum, slowing down or postponing the evacuation reflex. Slow intestine activity or long stay of food in the body is involved in common intestine illnesses from which a large part of the population suffers. Sitting with good posture would be a strong preventive measure. 

Knee and hip joints


When using a conventional chair, there is a 90 degree angle between the thighs and the upper body, as well as in the knees. The sharp angle tightens the main tendons and ligaments and creates more pressure on the cartilages. This has a harmful effect to the metabolism of the hip and knee joints. In traditional sitting, the weight of the upper body increases the pressure on the hip joint upper cartilage. On a saddle chair the hips and the knees are in a 135 degree angle, which decreases the pressure on the cartilages. This improves the metabolism and reduces the risk of joint ailments. Being higher than the average office chair, the saddle chair is also healthier for the knees when standing up.

Lymph flow

There is lymph liquid and 4–6 litres of blood in the human body, the lymph being filtered in 600 –700 lymph nodes. All liquid is moving through 400.000–500.000 km of vessels, 7.000 km in each kg of soft tissues. Only one litre of the blood is moving because of the pumping pressure of the heart. The rest of the liquids move because of the motions and activity of the muscles and other soft tissues.
Our conventional and modern habits of slouched sitting, tight clothing, poor nutrition and physical inactivity greatly disturb these sensitive systems. This results in various health problems and discomfort. The sensitivity of the circulation can be demonstrated by closing a vein on the back of the hand by pressing it ever so slightly with a finger. This illustrates in a small scale how dramatically the circulation must be disturbed because of our circulation-hostile lifestyle.
Using a two-part saddle chair will significantly reduce the pressure on the soft tissues in the pelvic area, keep the clothes looser, widen the angles of the limbs and activate muscle function, thus activating circulation and the lymphatic system. The effect is most powerful in the typical pressure areas (caused by conventional office chairs), such as thighs, buttocks, genital area, back and lower limbs. Blood circulation speeds up also in the typical tension areas, such as the upper back.
Lower limbs benefit from the riding-like sitting too, since the hip and knee angles become wider, making it easier to use the legs and enabling the so called "muscle pump” to work properly. Sitting bones carry most of the body weight, which in turn eases the pressure on the thighs and buttocks. For example, the Gluteus Maximus muscle remains safely outside the pressure area.
A smart sitter also uses loose trousers or skirt, and underwear that are not too tight. The most beneficial alternative for the circulation would be to use loose-fitting clothes that do not press the waist.

Shoulder joints and mouse-hand syndrome

Shoulder joint problems are common in professions where the angle between the upper body and the upper arm is more than 30 degrees, for example, in dentistry. When using a saddle chair, the angle usually stays smaller than 30 degrees and helps to prevent shoulder joint problems.
The detrimental, sharp angle of the wrist, repetitious movements and muscle tensions, together with pinched nerves in the shoulder area, cause most mouse-hand problems. Relieving pressure from the neck and shoulder area, and finding the correct place for the shoulder while sitting in a good posture, also helps in getting rid of the mouse-hand problems. Good posture and good hand support with almost straight wrists prevents the problem.
