Hero 275H Series Executive Chairby Interstuhl
| Accessories |
The Hero 275H Series Executive Chair from InterStuhl features a seat back engineered to adapt automatically to the weight of the user, providing a unique balance of comfort, ease and support tailored to every individual, and a versatile, adjustable headrest.
To ensure users of all weights are properly supported when leaning back in the chair, the return force of the seat back is regulated by an Autofit Synchro Mechanism that can then be fine-tuned manually if desired. The seat back provides adjustable lumbar support and is made of high quality semi-transparent mesh with opaque, horizontal tension stripes that deliver excellent breathability and support for the entire back. In addition to its upright position, the seat back has an infinite range of lean-back positions. A separate mechanism allows the relative positions of the seat and seat back to be locked at four distinct angles greater than 90°, with an impressive maximum angle of 126°.
The headrest is height adjustable to accommodate the most petite users, and tilts freely on a central axis ensuring a comfortable angle of support as the user adjusts position in the chair. Additionally, the headrest on the Hero 275H Series Executive Chair can be locked into positions up to 3" forward of the seat back to offer relief for the neck muscles even while the user is sitting fully upright at the desk.
The seat pan on the Hero is tilt adjustable, height adjustable from 18" to 22.5", and has an intuitive hand-operated rolling mechanism to extend or reduce its depth (front to back) by up to two inches. Together, these features allow users of all heights to benefit from a seat that is custom sized and optimally positioned. The seat fabric is high grade commercial polyester rated at 400 g/rm.
An even higher degree of adjustability characterizes the T-armrests on the Hero. To allow users of all builds to meet their individual needs for arm support, the "4-D" armrests are adjustable for height, width (from the inner edge of the left armrest to the inner edge of the right armrest), depth (forward and backward) and full swivel (360°).
The Hero 275H Series Executive Chair is available with a dual density mesh back in a striking contemporary anthracite, or in a more conservative black. All chairs come with soft-surface double casters and a durable aluminum base powder-coated in Brilliant Silver.
Adjustable Headrest Offers Neck Support
- The Hero 275H features a comfortable tensioned mesh headrest that is adjustable in both Depth (2") and Height (3.25"). The depth adjustment permits the headrest to be moved a full 2" forward towards the user - making it able to achieve some degree of neck support without having to lean back in the chair.
Helps to Improve the Health of the Body's Systems
- The conventional seated position (i.e. 90º bend) restricts both blood and fluid flows through the internal organs. The Hero 275H Executive Chair is able to open all the way up to 126º. Regular employment of this feature can benefit the internal operations of the body by reducing potential restrictions in the digestive tract and permitting the diaphragm to move more freely which in turn can significantly increase cardiovascular activity.
Can Reduce Neck and Shoulder Issues
- The Hero Executive features 4-D armrests with an extensive range of adjustment in width, depth, height, and angle (full 360° rotation). These adjustments enable each user to position the armrests to offer support where it will provide the greatest benefit, while yet remaining easily adjustable should changes in tasks warrant. Adjusting the armrests as needed ensures that the shoulder joints are not overloaded and that the muscles of the shoulders and neck are not overstrained. A side benefit of this can be a reduction to the risk of development of muscle tension which can lead to performance-reducing or potentially debilitating headaches.
Increases Mental Alertness
- The "open torso movement" feature on the Hero Executive can naturally increase cardiovascular activity. This moves more oxygen to the brain and contributes to a greater degree of mental alertness which can lead to greater productivity as users may also find themselves able to remain alert and comfortable for greater periods.
Reduces Risk of Lower Back Pain
- The Hero Executive Chair offers an extensive range of adjustments which enable individual users to configure the chair to best suit their body type and task requirements. Multiple levels of lumbar support, adjustable in height and pressure, ensure that the back receives the appropriate support for each user, adjustable resistance on the backrest permits users to adjust the chair to match their body weight and preferences, and a tilt-adjustable seat pan assists the user to achieve a correct spinal alignment to reduce stress on the lower end of the spinal column.
Offers Core Muscle Toning
- The Autofit Synchro Function can be utilized to encourage the toning of muscle. By regularly employing the range of movement offered by the Hero these muscles are engaged to a much greater degree as compared to static sitting. This can either be accomplished on a consistent basic throughout the workday through the small adjustments users make as they shift between tasks or on a more pro-active basis by making a point to regularly lean back through the full range of movement, even doing so several times in a row. This will also have the added benefit of encouraging cardiovascular activity with the associated improvement in overall alertness.
Can Reduce General Fatigue
- Movement is key to ensuring that worker fatigue is controlled. Static sitting at a workstation reduces blood flow and encourages shallow breathing. Combined these result in a reduction in oxygen to both the brain and body tissue, contributing to overall fatigue. By avoiding the use of the backrest "lock" and permitting the chair to flex with you as you move blood flow will be increased and you will naturally breathe deeper as you open up the angle of the chair.
Encourages Active Movement
- The range of movement offered by the Hero Executive Chair encourages regular movement which keeps lubricating fluid moving through joints, reducing or eliminating stiffness, and also actively stretches muscles which can become shortened from extended static sitting. Use of the "lockout" feature for the backrest should be limited to those occasions when an upright fixed working position is required. Setting the backrest resistance to provide a firm degree of support while still permitting movement offers a very similar support while still permitting regular consistent movement throughout the day.
Can Reduce Risk of Circulation Restriction in Lower Legs
- The innovative "roll-back" mechanism with which the Hero is equipped lets users adjust the depth of the seat pan to fit their body dimensions. This ensures that they receive the necessary support while at the same time ensuring that there is clearance behind the knees. This function also creates a "waterfall" front on the seat to eliminate the potential for any sharp edges against the back of the legs.
Encourages Correct Posture at Workstation
- Seat height is easily adjusted using a simple hand release. This enables users to easily set their seat to a height appropriate to their build, optimizing their posture at their workstation.
Encourages Best Positioning by Users
- The Hero encourages users to take an active interest in their chair, to adjust it as needed to optimize their comfort. A generous range of adjustments are available, easily accomplished, and easily repeated. This discourages a "set it and leave it" approach which can occur with seats which have complex mechanisms with benefits that are hard to ascertain the immediate effects of.
- Breathable Mesh Back: The Hero 275H features a comfortable dual density mesh back which provides body contouring support. The mesh is breathable for increased user comfort.
- Adjustable Headrest: The Hero 275H features a comfortable tensioned mesh headrest that is adjustable in both Depth (2") and Height (3.25"). The depth adjustment permits the headrest to be moved a full forward towards the user - making it able to achieve some degree of neck support without having to lean back in the chair.
- Autofit Synchro Mechanism: The Hero features an Autofit Synchro Mechanism which enables a user to lean freely lean back in their chair. The mechanism automatically adjusts the resistance to match the weight of the user and includes a fine-tuning control for ideal comfort. The movement achieved by the Autofit Synchro Mechanism can be used to avoid the potential risks of static sitting, even when remaining seated. It also enables users to adopt varying postures throughout the day, opening the torso angle up to 126°. For situations where the freedom of movement may interfere with work this feature can easily be "locked out" at 90° or at one of four additional leaning positions using a button adjacent to the seat.
- Adjustable Resistance: The Autofit Synchro Mechanism features adjustable resistance which can be set for the weight and comfort of each individual user. The adjustment range will cover users weighing from 100 - 264 lbs (45 - 120 kg).
- Autofit Synchro Lock Option: Users can choose to limit the range of movement on the Autofit Synchro Mechanism by engaging the Lock function at one of 5 positions - This way they can change the degree of movement throughout the day and to best suit the nature of the particular task being undertaken at any time.
- Adjustable Lumbar Support: The Hero has a significant lumbar curve built into the contoured form of the back. This combines with the tensioned mesh to provide firm yet flexible support that contours to the back of the user, providing a "natural" support in just the right place. This support can be further enhanced by an adjustable Air-Pressure-Technology bar which backs the mesh. This lumber cushion offers 1" of infinitely variable depth adjustment and a 2" range of height adjustment with five indexed stopping points.
- Load-Dependent Casters for Hard Floors: The Hero is equipped with soft 65 mm load-dependent casters for safety. This means that the chair will not roll away from the user when they stand up. These casters do not lock, they only exert just enough resistance so that the chair does not roll on its own when weight is removed, allowing users to re-position the chair with minimal effort. When the chair is occupied the brake fully disengages, permitting the user to move in the chair as required with no resistance.
- Tilting Seat: The Hero offers an infinite range of seat inclination adjustment from 0° to -4°. As the seat tilt originates from the rear of the seat there is no need for adjustment of back height or seat positioning when the inclination is adjusted. The seat remains in correct alignment to the back regardless of the angle selected.
- Depth Adjustable Seat: Unlike most traditional office chairs, the Hero employs a unique "rolling" mechanism which permits the front edge of the seat to be rolled "in" or "out" to shorten or expand the depth of the seating surface. This performs the same function as the more common "sliding" seat pan but with an added benefit. A sliding seat pan will change the alignment of the seat to the back, especially the position of the area designed to provide the most support for the weight of the user. In addition, a sliding seat pan also changes the space or "gap" between the seat and the back, potentially creating an uncomfortable seating arrangement for users who require a deeper seat pan. The Hero addresses this issue by maintaining the same seat-to-back alignment regardless of the size or build of the user. By moving the seat pan adjustment to the front, the Hero provides all users with an optimum seating position where they are best able to benefit from all the features of the chair.
- "Waterfall Front" Seatpan: The Hero is equipped with a "waterfall" front to reduce the risk of unnecessary pressure being exerted against the back of the thighs. To accomplish this the front of the seat is "rolled" down and away from the leg. This feature is also what provides the seat pan depth adjustment.
- Removable 4-D Armrests: The Hero features 4-D Armrests that are adjustable for height, width (from the inner edge of the left armrest to the inner edge of the right armrest), depth (forward and backward) and pivot (180° to the left and right). See "Specifications" below for detailed range of movement. If desired the armrests can easily be detached using a simple Allen key.
- Sturdy Base: The Hero 275H sits on a sturdy 5-point Aluminum base powder-coated in Brilliant Silver (see image in gallery)

- Adjust the Head Rest to provide support when the neck is in a "neutral" position. You want support that prevents the head from tipping backwards when reclining but at the same time not pressing it forward of the shoulders.
- Adjust Seat Pan Tilt When Chair is Unoccupied - It is not advisable to attempt to adjust seat tilt while the chair is in use. The seat tilt adjustment is not intended to be performed under loaded conditions and damage can be done to the tilt adjustment mechanism.
- Armrest Width should be set so that adjustment can be made both narrower and wider as needed. The primary mechanical setting (via Allen key) should be performed with the armrests in neutral (2 index points in), flat side facing in. This will enable users to achieve 3" (1.5" in and 1.5" out) of width adjustments by combining the lateral ratchet range and the 180° rotation without the need of tools.
- Adjust the Armrests to Match Your Build - Users with smaller builds may wish to rotate the armrests so the curved edges face in, positioning the armrest in close proximity to the backrest. This better situates the armrest surfaces for optimum support of the upper arm.
- Make a point of actively engaging with the Autofit Synchro movement throughout the day. While you may choose to lock out this feature while performing specific tasks, to do so permanently will eliminate a key feature which makes this chair successful.
- Fine tune the resistance tension of the Autofit Synchro Mechanism to match your comfort. While the Autofit feature will automatically compensate for your weight most users still choose to create a more personal degree of resistance. Adjustment is gradual and may require several turns of the adjustment control.
- Adjust the armrests to provide support when in a neutral position, with elbows resting comfortably at your sides and shoulders relaxed. The 4-D armrests are highly adjustable and can easily be repositioned when moving between task types.
- Use the seatpan roller to shorten or lengthen the seatpan to suit the length of your thighs. You want to have 1-2 finger widths between the back of your knees and the front of the seatpan.
- When adjusting the height of your Hero, aim for an elevation which lets your elbows open slightly more than 90° while your hands are resting on the keyboard or mouse. If your feet are unable to rest flat against the floor you may need to add a footrest to your workstation. If you are too low and the angle of your legs and torso is less than 90 then you should raise your chair to the appropriate level while also raising your input devices to a similarly appropriate height.
