In the past, most neck supports were not adjustable, but were instead a feature solely for executive chairs. This is still evident in places like courtrooms, where presiding judges often have chairs with a neck support or a higher backrest than their colleagues.
In 2000, Sedus introduced the new ‘Similar’ mechanism that allowed a 28° recline in the backrest support. The ‘open up’ swivel chair model integrated a dorsokinetic backrest joint which, when combined with this mechanism, enabling a fully reclining position, ideal for activities such as a ‘power nap’. The dorsokinetic mechanism allows for backward movements as well as rotations or torsions of the spine, therefore accommodating the natural range of upper body motion.
What about a neck support that is used at a computer workstation for varying periods of time?
Neck support for backward-leaning posture
In most cases, a backward-leaning posture requires a swivel chair with a large body opening angle. That is why such a posture is perceived as relaxing and comfortable. The internal organs are not pinched and the centre of gravity of the upper body and the resulting weight are absorbed by the backrest. Consequently, the trunk muscles can relax, which simultaneously reduces the load on the intervertebral discs.
However, this position also means that the head is bent forward to be able to look at the monitor. If this happens over a longer period of time, the shoulder and neck muscles have to perform ‘static holding work’. If you do not move regularly, this can lead to shoulder and neck tension.
According to recent research, the importance of making as many movements as possible (even small ones), is beneficial to maintaining physical well-being. However, during periods of intense concentration, users often forget to shift position and change posture. In these cases, an adjustable neck support can provide essential relief by offering adaptable support across a wide range of positions.
The right setting is crucial
A neck support should be adjusted according to the distance between ‘eye level and seat’. Depending on the user's height, a height-adjustable backrest can also be an advantage if the adjustment range of the neck support alone is insufficient. The depth adjustment of the backrest also plays a crucial role.
One example of a use for neck supports outside of a traditional office setting is in a control room, where a wide field of vision is viewed for extended periods. A reclined sitting posture to support the head and relieve the neck over longer periods of time is also beneficial.
A properly designed neck support can be very helpful for the individual user – provided that guidance on its proper use is given. The neck support is intended to provide relief, but should not lead to a sedentary posture – every opportunity to stand up and walk should be taken to maintain overall well-being.
