The ErgoBack Ergonomic Chair – A ‘LumbarSaver’

The ERGOBACK stands out as an exceptional ergonomic chair, offered in both executive and task chair variations. Its standout feature is the extendable and fully adjustable lumbar support, catering to individuals in need of extra lower back support.

This chair comes equipped with standard features such as an adjustable headrest and multi-adjustable armrests. Furthermore, its remarkable design includes a weight-sensitive synchronous swivel and tilt mechanism with an integrated seat depth adjustment.

The ErgoBack has a 150kg weight rating and carries a 10-year warranty.

1. Backrest adjustment

The backrest on the ErgoBack can be adjusted to specifically suit your spine and prevent or reduce lower back pain. The synchronous (synchro) mechanism enables you to simultaneously adjust the backrest and seat angle. The backrest and seat move in a fixed 2:1 ratio, meaning for every 2° of backrest movement, the seat will move 1° in the same direction. This motion can be securely locked in various positions or left in an unlocked, free-floating mode. In this mode, the backrest maintains continuous contact with your back, adapting to your movements. For acute cases, the ErgoBack has a unique an extendable lumbar support.

2. Seat depth adjustment

The seat slider on the ErgoBack empowers you to fine-tune the seat depth, enabling you to move the seat pan backward or forward to align with the length of your thighs. When you are seated comfortably with your back against the backrest of the chair, there should be a 2-3 finger gap between the front edge of the seat and the back of your knees. This practice not only prevents strain behind the knees but also provides optimal upper leg and under thigh support, promoting good blood circulation.

  • For taller individuals with longer legs, a seat slider allows you to INCREASE the seat depth, thereby maintaining a correct ergonomic seated posture. Conversely, a shorter person should consider REDUCING the seat depth. If the seat is excessively long (deep), anyone with shorter legs might find themselves sitting on the front edge of the seat, leading to a lack of adequate back support.
  • If you have a coccyx-related issue, a chair featuring seat depth adjustment can be invaluable. This customisation capability allows you to tailor the seat depth to alleviate pressure on the coccyx, contributing to enhanced comfort and wellbeing.

3. Armrest adjustment

The armrests on the ErgoBack are multi-adjustable. This allows you to position the supporting pads for optimum comfort while you work.

In addition to vertical height adjustment, the arm pads can be adjusted horizontally and also pivoted inwards/outwards.

The ErgoBack has a synchronous mechanism that promotes Dynamic Sitting.

ergoback ergonomic chairDynamic sitting occurs in an office chair that is fitted with a mechanism that allows the angle between the backrest and seat to change. By continuously changing this angle, you automatically stimulate, or activate various muscles in your lower back, core and legs. As a result, the blood flow through these muscles increases, bringing oxygen and other nutrients to the muscles and carrying away the waste products of muscle metabolism. By doing so, muscle fatigue and it’s associated pain is reduced, particularly in the lower back, core and legs.

A synchro mechanism ensures that the movement of the backrest is always greater than that of the seat.

The tilt mechanism on this chair allows the seat and backrest to move relative to each other in a fixed 2:1 ratio.
In other words, for every 1 degree that the seat tilts, the backrest will move 2 degrees in the same direction.
