The Activ Ergonomic Chair – Medically Endorsed Ergonomics

The Activ ergonomic chair has been at the forefront of seating technology in South Africa for many years. The Activ’s impressive features include a state-of-the-art frontal-pivot synchro swivel mechanism, multi-adjustable armrests, and a highly adjustable lumbar support. It is little wonder that this chair has been endorsed for its ergonomic features by Dr. JJ Gilau, a specialist in neck, back and shoulder pain rehabilitation. 

This is a chair that guarantees top-class ergonomic support and comes with a 10-year warranty and a weight rating of 150kg.

1. Backrest adjustment

The Activ’s backrest offers tailored adjustments to support your spine and alleviate or minimise lower back discomfort. Its synchronous (synchro) mechanism allows simultaneous customisation of the backrest and seat angles. The backrest and seat seamlessly move in a fixed 2:1 ratio, ensuring that for every 2° of backrest adjustment, the seat follows suit with a 1° movement in the same direction. You can securely lock this motion in various positions or opt for an unlocked, free-floating mode. In this mode, the backrest maintains constant contact with your back, adapting to your movements.

An innovative feature of the Activ is its frontal-pivot synchro mechanism, ensuring that when you lean backward, the front edge of the seat (point A) stays at a consistent height. This unique design enhances sitting comfort by preventing your knees from lifting up and increasing the pressure on the underside of your thighs. The result is a more ergonomic and enjoyable sitting experience. 

2. Seat adjustment

The Activ does not have a seat slider for adjusting the depth of the seat. If you are above average height with long legs or have a coccyx-related concern, the absence of a seat slider may render this chair unsuitable for you. In such instances, we suggest opting for an ergonomic chair equipped with a seat slider. If you are unsure, it is advisable to complete a sit-test on the Activ to assess whether the seat depth is suitable for your needs. Visit our showroom to conduct a sit-test on the Activ. 

3. Armrest adjustment

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

In addition to vertical height adjustment, the width between the arms can be independently set for each armrest. Finally, the arm pads can be pivoted inwards/outwards.

The Activ has a synchronous mechanism that promotes Dynamic Sitting.

activ 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.
