4 Treston Workplace Chairs A workplace chair must be equally good fit for anyone and everyone – men and women, small people and large, heavy and light, and young and old – which is why it is essential to have a sufficiently wide range of settings and adjustments. See here the different adjustment possibilities of Treston workplace chairs. Adjustments and features of Treston workplace chairs Permanent contact backrest … follows the movements of the upper body, and ensures that the back always remains fully supported. Ideal for people who have to lean forward for long periods of time, with only a small distance between eyes and workplace (e.g. working in precision engineering or in the laboratory). Synchronous mechanism … provides an active-dynamic sitting experience with weight regulation. The seat and backrest accompany to body as it moves. This gives the user a feeling that can best be described as ”weightless floating”. The synchronous technology comes into its own where users are working at office type working situations, working at a screen, or constantly changing their sitting position. Armrests Armrests have the important function of reducing the strain on the upper body and arms. The height, width and depth of 4D armrests can be adjusted, and can also be swiveled. Backrest height Ensures that a person is ideally supported – especially in the lumbar region – no matter how tall he/she is. Weight regulation By individually adjusting the pressure of the backrest, both light and heavy people can sit with the correct posture. Seat depth Matches the depth of the seat to the size of the body, giving the best possible contact surface for the thighs. Contact with the backrest, and therefore the support it provides, are maintained. Seat tilt Many jobs are carried out in slightly raised positions, and require people to bend forwards. A correspondingly tilted seat provides a seat angle of at least 90 degrees, while at the same time providing contact with the backrest. Seat height Allows adjustment to body size and height of workplace. The ideal seat height is when the knees, hips and elbows form an angle of at least 90 degrees, with the feet resting flat on the floor. Seat and back rest adjustments Back rest mechanisms and arm rests
5 Treston Workplace Chairs The backrest supports the lower back; find out simultaneously the convenient angle of the backrest. The backrest supports the lower back, and the front edge of the seat does not press the lower limbs. Upper arms are close to the body, shoulders relaxed, forearms naturally. Feet are supported on the floor, and the back leans on the backrest. A forwards-tilting seat reduces the stress in lower back. How to adjust your Treston workplace chair Ergonomically sound chair is a vital part of a well-functioning, ergonomic and user-friendly workstation. Good sitting enables effective and appropriate movements, reduces postural fixity and enables good and relaxed working postures. Chair alone, however, will not improve your workplace ergonomics, you have to adjust the chair according to the person using it – adjust the chair, not the person. When taking into use your workplace chair, make sure to follow the adjustment guidelines below. !

6 Treston Workplace Chairs The ergonomic requirements of workplace chairs in industrial and technical environments are inherently different to those of other areas, such as offices. The jobs carried out at manufacturing workstations may involve force, precision skills and repetitive movements, and it is not always possible to adopt an ideal position in relation to the work piece. A workplace chair must adapt perfectly to the working environment and to the person, in order to Are you sitting well? A short introduction to workplace chair ergonomics enable necessary actions when seated – without adopting unhealthy positions or unnatural postures and without affecting productivity and efficiency. A good workplace chair adjusts easily to the person using it and supports the person doing the task in various working positions. Adjust the backrest so that its curvature supports the spine in the are of the 3rd and 4th lumbar vertebrae (approximately belt height). The bottom should be right at the back of the seat to fit its anatomically shaped contours. Only this posture ensures a contact with the backrest so that the user benefits of its support. The seat should slightly be inclined towards for jobs involving fine motor skills. Ideally, the chair will have a seat depth adjustment mechanism allowing the optimum setting for the length of the thighs. The seat is at the correct height when the upper arms and forearms for a right angle and the forearms are level with the working surface. At the same time, the angle between the thighs and lower legs should be at least 90 degrees. The feet should be flat on the floor or on a footrest.

7 Treston Workplace Chairs Task Primary choice Secondary choice Lifting the weight over 5 kgs Standing Semi-sitting Working below the elbow level Standing Semi-sitting Need to reach widely in horizontal level Standing Semi-sitting Light assembly work Sitting Semi-sitting Precision work Sitting Semi-sitting Visual monitoring or supervising Sitting Semi-sitting Need to move between workstations Semi-sitting Standing If tasks require paperwork, typing, no heavy lifting, and/ or all tools for the job are provided in arm’s reach, then the workstation should be designed for sitting, but with possibility to stand. Latest cognitive research shows how beneficial changing working posture can be. It’s been studied that even slight movements, like standing up every now and then, improve memory, attentiveness, learning and ultimately cognitive performance. So what better way to improve the efficiency of a desk-tied person? If tasks require lifting heavy loads, continuous movement, parts retrieval, and/or there is no leg space, then the workstation should be designed for standing but with the possibility to rest every now and then, whenever possible. Do note however that even though stand up working posture is becoming increasingly popular, many official recommendations still state that proper seating ergonomics is one of the most crucial aspects of preventive actions for work related musculoskeletal disorders. Therefore it is not indifferent how and on what you are sitting, when you are sitting! See below general tips on different work tasks and choosing the right working position. Semi-sitting between sitting and standing; reduces the strain of the back due to sitting and the strain of the lower limbs due to standing. Sitting or standing? ! When seeking out potential solutions, consider chairs, standing rests, saddle chairs, footrests and easily adjustable workbenches, which allow for both sitting and standing work that may be most suitable for your environment and staff.
