How chair mechanisms support the individual sit better – work better

When working at a desk, it is important to have a chair that provides support in order to sit comfortably and maintain good posture. There are many different chair mechanisms that serve this purpose, and each has its own advantages. For example, a mesh back chair promotes airflow and helps to keep the back cool, while a contoured seat provides support for the legs and helps to prevent fatigue. In addition, adjustable features such as seat height and armrests allow the chair to be customized to the individual’s needs, ensuring that they can maintain a comfortable and supportive position. By carefully selecting a chair with the right mechanism, individuals can greatly improve their sitting experience and work more effectively.

Synchro 2:1

Supporting the pelvis and lower back whilst keeping feet firmly on the floor.

Balance

Similarly to the Synchro, the Balance mechanism offers a free float mode.

The internal mechanism automatically adjusts the tension to the individual

user’s weight so that the seat and back move whilst still supporting the pelvis and lower back.

ISB – Independent Seat and Back

Using an ISB mechanism allows the seat and back to be adjusted separately to suit the individual needs of the user. It is important to adjust the chair to encourage the correct posture as well as the individual’s needs in relation to the tasks they carry out day to day. It is not advised to leave the seat and back unlocked together.

For example if used for lots of reading and writing a more forward position is required where the seat and back both need to be tilted forward slightly. However most prefer the seat and back to be tilted more towards the rear of the chair for tasks on screen.

PCB – Permanent Contact Back

A PCB mechanism is the most basic of mechanisms and therefore the most simple to set up. The seat does not adjust, however the back tilts forward and backward separately to the chair.

The back is best left unlocked to encourage movement and for the user to permanently have contact with the backrest. This supports the pelvis and lower back whilst still keeping the user’s feet firmly on the floor.
