The Svenstol S5 sets new standards among control room chairs and is specifically designed for continuous use. It is ideally suited for shift work environments with high demands on adjustability, seating comfort, and durability.
The activePlus mechanism and ergonomically designed backrest promote continuous movement around the clock. This office chair is built for changing sitting postures, extreme positions, and heavy use. With the use of special construction techniques and steel as a material, it boasts an extremely robust chassis.
The Svenstol S5 is also suitable for individuals with a body weight of over 150 kg and promises durability even under extreme stress.
This armrest is specially designed for use with the Svenstol and its continuous 24-hour usage. It features a robust PU pad and a high-quality aluminum support, both engineered for long-lasting durability. The adjustment of the armrest can be achieved within 2 seconds thanks to a specially developed mechanism.
Highest tilt stability
The 6-arm base is specifically designed for use in 24-hour chairs to maximize both comfort and stability. Equipped with six support arms, it provides a solid foundation and reduces the specific load on the base and wheels by 20%, making the Svenstol® remarkably maneuverable despite its size. The robust design of the base also ensures high tipping safety, even in extreme sitting positions. In combination with supportive elements such as frame and high-quality mechanics, this base enables an active and secure seating posture.
Control room chairs are subject to up to seven times more stress than conventional office chairs, which is why they are designed with reinforced mechanics and a robust construction to ensure high durability.
The upholstery of the Svenstol S5 is made from particularly abrasion-resistant fabrics that have been tested for up to 500,000 rub cycles. The upholstery is additionally reinforced with cut and tear-resistant material at particularly stressed areas. These features make the chair suitable for individuals who carry weapons and require increased durability.
The 24-hour chairs from StolComfort come with a comprehensive five-year full warranty valid in Germany, Austria, Switzerland, France, the Netherlands, Belgium, Luxembourg, Sweden, and Norway.
This warranty covers all parts and costs associated with repairs, including all materials, labor, transportation, and travel expenses.
Conventional office swivel chairs prove insufficient under the conditions in control centers as they cannot withstand continuous use and quickly become defective. The 24-hour chairs from StolComfort are designed for intensive use: they are used by many people, frequently adjusted, and must withstand extreme seating positions as well as a higher average user weight.
The Svenstol S5 is highly flexible despite 10 KG of steel built into its robust design. It is specially designed for environments with frequent shift changes, where easy and quick adjustments are essential. With almost every user change, the backrest, headrest, seat cushion length, armrests, lumbar support, and seat height must be readjusted. These components can be adjusted quickly and intuitively to provide every new user with optimal comfort and support.
The flexible adaptability of these chairs ensures that they can effectively meet the individual needs of each user. Their ergonomic design promotes a healthy sitting posture that not only enhances well-being, but also maintains productivity and concentration over longer periods of time. With this optimized support, the chairs enable efficient work and improve the overall user experience.
The Comfort Headrest is designed to provide optimal support for the neck and shoulders, especially during long periods of sitting. The daily burden of supporting the head’s weight significantly strains the shoulder and neck muscles, often leading to pain and tension.
This headrest allows for individual adjustments in height, tilt, and depth to offer effective support in any sitting position.
The Svenstol S5 office chair features a record-breaking tilt angle of 44 degrees, allowing you to lean back, discover new perspectives, and simultaneously relieve intervertebral discs and muscles.
This feature provides excellent support for longer and more comfortable sitting by enabling a deep relaxation posture. The generous tilt angle supports a healthy sitting posture and enhances well-being in the workplace.
The Svenstol S5 offers an innovative solution for easy adjustments, ideal for 24/7 workspaces with frequently changing users. On the right side of the seat, there is a label with a QR code. Users can easily scan this QR code with a smartphone to access video instructions for all models. This smart assistance facilitates the quick and correct adjustment of the chair, ensuring optimal customization to individual needs.
With intensive use, even high-quality office chairs like the Svenstol 24-hour chair can exhibit signs of wear. To restore the ergonomics and comfort of the first day of use, the seat cushion of this chair is easily replaceable. This allows for a quick and easy renewal of seating comfort without having to replace the entire chair.
Service First-Hand
Even high-quality chairs like the Svenstol are subject to wear and tear after years of continuous use. To ensure the longevity and optimal functionality of these chairs, utilizing the specialized maintenance service is advisable. This service includes annual inspections and cleanings of the Svenstol 24-hour swivel chairs. Regular maintenance keeps each chair in optimal condition, significantly extending its lifespan.
The ComfortPlus cushioning is specifically designed to reduce pressure point stress, prevent tension, and support longer concentration periods. This optimization of pressure distribution is achieved through a thoughtful combination of shape, surface texture, density, firmness, cell structure, as well as the spring and damping of ergonomic cold foam.
Additionally, the maximum contact area ensures optimal distribution of body weight and promotes a comfortable sitting experience.
The infinitely adjustable seat depth of the Svenstol S5 allows the usable seat area to be adjusted by up to 10 cm in the range from 41 to 51 cm. This means the chair covers body sizes from the 5th to the 95th percentile and ensures that the ergonomically correct distance of two to four finger widths is always maintained between the back of the knee and the front edge of the seat.
A seat that is too short does not properly support the thigh, while one that is too long cuts into the back of the knee and restricts circulation. In multi-user operation of a control room chair, this distance can be corrected within seconds when shifts change.
The activePlus mechanism of the Svenstol S5 is the foundation for active, dynamic sitting in professional 24/7 use. It moves the seat through a total range of 25°: from −6° in the forward tilt to +19° in the recline position.
The forward tilt of up to 6° is especially valuable from a biomechanical point of view: it opens the pelvic angle, gently tilts the pelvis forward, straightens the lumbar spine and supports its natural S-shape. This helps counteract rounding of the lower back.
The mechanism works with a highly durable torsion spring and offers simple weight adjustment. This stepless kinematics ensures that intervertebral disc pressure, muscle activity and pressure distribution are regularly changed and redistributed throughout the entire shift.
Regardless of the seat tilt, the backrest has its own tilt axis that can be continuously adjusted by around 25°. Together with the seat movement, this creates the characteristic opening angle of up to 44°.
Practically, this means: the backrest follows the movement of the upper body while maintaining contact with the lumbar spine and guiding it continuously. A side lever allows the backrest to be locked in any position.
The standard gas spring of the Svenstol S5 covers a seat height range from 44 to 56 cm, making it suitable for people with a height of around 160 to 195 cm at a standard workstation. Optionally, a low gas spring (39 to 47 cm) is available for smaller consoles, or a high gas spring (48 to 60 cm) for standing desks and elevated control stations in industrial control rooms and Skyguide towers.
The infinitely variable pneumatic system responds immediately to the release lever and can be adjusted with pinpoint precision. When set correctly, the angle between the upper and lower leg is about 90°, and the feet rest flat on the floor, which is essential for fatigue-free shifts in a 24-hour chair and for a seating posture at a screen workstation that complies with DIN EN 1335.
The pneumatic lumbar support with two air chambers provides targeted support for the lumbar spine in the area of the natural lordosis. The depth of the curvature can be adjusted individually to suit the shape of the back and personal comfort preferences.
Using a magnetic hand pump, both air chambers can be filled continuously and independently of one another. This allows the lumbar support to be adjusted with exceptional precision to match the user’s individual spinal curvature. A release valve enables exact reduction of air pressure.
For shift-work chairs, the two-chamber pneumatic system offers a clear comfort advantage over mechanically adjustable lumbar supports with handwheels: it not only allows the support intensity to be adjusted, but also provides differentiated support for different areas of the back.
As a highly robust alternative to the pneumatic version, StolComfort offers a mechanical lumbar support. It can be conveniently adjusted while seated using two easy-grip handwheels, which are integrated directly into the back of the control room chairs.
The user can precisely adjust the curvature of the backrest to their lumbar spine, both in height and depth. Unlike the pneumatic solution, the mechanical version is completely maintenance-free, without pump bellows or valves, and retains its setting permanently.
The resistance of the backrest must harmonize precisely with the user’s physique. The activePlus mechanism of the Svenstol S5 features stepless weight adjustment from 45 to 150 kg; in the 150+ version, the adjustment range extends up to 200 kg. This allows the backrest counterpressure to be precisely matched to the user’s body weight.
Using an easily accessible handwheel beneath the seat shell, the tension of the heavy-duty spring can be adjusted in just a few seconds, without tools, without a scale, and with an immediately noticeable result.
When the counterforce is correctly calibrated, the user moves in a balanced way in the chair: the backrest provides controlled support without giving way or pushing back too strongly. This promotes the interplay of load and relief and ensures biomechanically optimal backrest guidance, even with frequent user changes in shift work.
Control room chairs equipped with 4F technology offer the best ergonomic support. The fine-motor multifunction armrests, type 4F, are adjustable in four axes: height, depth (forward/backward movement of the pad), width (distance from the seat), and rotation direction (swiveling the support surface inward or outward). This 4D adjustability allows millimeter-precise positioning for every keyboard, mouse, or joystick position on a control console.
In an operations control center with multiple input devices per workstation, this adaptability is essential because it provides neutral support for the shoulders and wrists in every work situation. The soft PU pads are skin-friendly and abrasion-resistant, while the aluminum support carries the weight of the resting forearms reliably over time without any play.
The perfect combination of durability and ergonomic adjustment is offered by the fold-up Svenstol armrests with additional height adjustment. Specially developed for 24-hour chairs, they feature a reinforced aluminum support.
In addition to the ultra-fast flip-up function to the rear, this model can also be comfortably adjusted in height by up to 6 cm while seated. This flexibility is essential for bringing the forearm angle into a horizontal position.
The PU pads are soft, skin-friendly, and temperature-neutral.
The Svenstol S5 relies on a restrained, functional design language with clean lines, a polished aluminium surface, and consistently reduced design elements.
This aesthetic deliberately takes a back seat to the function of a 24-hour chair and fits seamlessly into architectural environments that are highly functional themselves: modern control rooms with large-format LED walls, emergency call centers with indirect lighting, and air traffic control towers with glass façades.
This keeps the chair visually calm in any setting and makes an impression through material quality rather than decorative effects.
For particularly high demands on load capacity and durability, the Svenstol S5 is available in the 150+ version. A reinforced seat plate, reinforced heavy-duty gas lift and reinforced mechanism increase the stepless weight adjustment to 45 to 200 kg and the static load capacity to up to 230 kg.
This means this version covers the full range of an XXL office chair or heavy-duty chair for 24/7 use, without compromising ergonomic adjustability or the mechanism profile. The 150+ version is typically used where either individual users with higher body weight sit in continuous operation or where the chair is used in three-shift operation by many different people and the design reserve should generally be generously dimensioned.
The back of chairs is often exposed to bumps from people passing by in the demanding day-to-day workplace. The Svenstol S5 can optionally be equipped with an impact-resistant plastic back shell. This robust cover protects the backrest mechanism, the upholstery seams and the edge of the padding from mechanical stress, such as when moving up to partitions, bumping into adjacent chairs in densely occupied control rooms, or cleaning with floor machines.
Cleaning cloths and mops glide over the smooth surface without pulling on fabric or leather. Aesthetically, this creates a clean, high-quality-looking rear view that makes a decisive difference in representative spaces.
The back shell features the embossed Svenstol logo and, in the standard version, is compatible with all backrest configurations except the mechanical lumbar support.
The optional removable coat hanger is mounted directly to the headrest of the Svenstol S5 and provides a neat place to store uniform jackets, service shirts, blazers or protective vests.
Without a dedicated storage solution, the jacket usually ends up draped over the backrest, distorts the upholstery, creases and interferes with the mechanism when reclining. The shape-retaining hanger keeps the garment in the correct shoulder form and protects both the chair and the clothing.
When not in use, it can be removed without tools and stored separately. The headrest remains fully functional. A small but noticeably practical addition to the 24-hour chair for everyday shift work.
To comfortably elevate your legs during rest periods, StolComfort offers the matching Svenstol stool. It complements the control room chair as a high-quality, height-adjustable footrest and provides additional comfort for shift work.
The stool is based on a stable 6-star base with glides and features stepless gas lift height adjustment from 40 to 52 cm. The padded support plate is covered in elegant black genuine leather.
Whether as an ergonomic footrest for control room chairs or as a separately usable stool in control rooms: the Svenstol stool blends visually harmoniously into the 24-hour chair system and offers shift staff a noticeable gain in ergonomic comfort and restorative flexibility.
Health protection and low emissions are essential in air-conditioned control rooms. The Svenstol S5 is awarded the renowned Blue Angel DE-UZ 117, the oldest environmental label issued by the German federal government.
This certification guarantees that the control room chairs are made from low-emission materials that do not release harmful volatile organic compounds (VOCs) into the indoor air.
The label also confirms the absence of hexavalent chromium and cadmium, the exclusion of perfluorinated chemicals (PFC), chloroparaffins, halogenated flame retardants and CMR substances, as well as strict limits for plasticizers, heavy metals and nitrosamines. Textiles and leather must also provide additional proof of harmful substances, such as OEKO-TEX 100.
24-hour chairs bearing this strict Type I ecolabel offer a working environment that is toxicologically absolutely safe. For control centers, emergency call centers and control rooms with long periods of use and often limited ventilation, this proof of harmful substances makes a direct contribution to indoor air quality and is a recognized award criterion for public-sector clients.
In multi-shift operation of control center chairs, each user’s head comes into direct contact with the same support surface. The disposable hygiene covers were specially developed as a precisely fitting protective layer for the 6-way comfort headrest of the Svenstol S5. With every change of user, they can be pulled quickly and easily over the headrest.
This effectively reduces the transfer of skin oils, sweat, and bacteria between employees. At the same time, the hygiene covers protect the high-quality upholstery materials of the control center chairs from premature soiling and wear.
The hygiene covers are supplied in packs of 100. Typical areas of use include medical dispatch centers, emergency call centers, fire brigade control rooms, as well as all working environments where hygiene standards in 24-hour chair operation must be reliably and traceably maintained. Integrating the hygiene covers supports a clean working environment while also increasing staff acceptance of the seating furniture.
On request, the Svenstol S5 is made with custom embroidery on the cover: logo, authority crest, department name, site designation or inventory code are applied precisely and in true color to the fabric or leather. The embroidery motif is usually placed on the headrest, the upper backrest or the side of the seat; position, size and color scheme are coordinated in advance using a template.
This factory personalization creates a professional, representative appearance in police control centers, fire department control rooms, emergency dispatch centers, military command centers and corporate control rooms, and underlines the corporate identity of modern organizations. At the same time, the personalization makes chair-specific allocation easier – for example by workstation or by shift group.
Police officers and security personnel place particularly heavy demands on control room chairs due to their heavy duty belts and equipment. The Svenstol S5 can therefore be optionally equipped with a special weapon carrier cover. In heavily stressed areas, especially on the side bolsters, the cover is massively reinforced with a special fabric that is cut-, puncture- and tear-resistant.
Hard edges of holsters, radios, handcuffs and other equipment rub against the cover every time the user stands up, turns or sits down. With conventional standard fabrics, this can quickly lead to visible signs of wear.
The weapon carrier cover is therefore a sensible standard configuration for control centers, correctional control rooms, military command centers, customs control centers, as well as all control room workstations with uniformed staff.
The Svenstol S5 is developed, manufactured and assembled in Lemgo (North Rhine-Westphalia). All load-bearing components, such as the mechanism, steel frame, aluminum five-star base and upholstery support, come from European production with a documented supply chain.
«Made in Germany» in this context means more than just origin branding; it has direct benefits for quality and service: short distances between design, production and final assembly, seamless quality assurance in accordance with ISO 9001, German occupational safety and environmental standards, as well as long-term spare parts availability through factory service. For buyers in Switzerland, European production is also advantageous from a customs perspective and enables delivery times that cannot be achieved with overseas imports.
24-hour chairs are suitable for any environment where employees need to sit for extended periods and require comfortable and ergonomic support:
