The Heathrow 24/7 Heavy-Duty Orthopedic Chair – Exceptional Strength

The Heathrow heavy-duty orthopedic chair stands out as a unique offering in South Africa, surpassing all others with its remarkable strength and array of features. From its impressive 180kg weight rating to the advanced Free-Float mechanism, the Heathrow is a genuine orthopedic chair. With additional features like multi-adjustable armrests and seat-depth adjustment, it’s no surprise that the Heathrow has maintained its unparalleled status for over two decades.

Every component of this heavy-duty chair has been meticulously designed to outperform and outlast conventional office chairs. A heavy-duty office chair, exemplified by the Heathrow, is one capable of handling rigorous demands and extended 24/7 use. The Heathrow boasts a weight rating of up to 180kg and is backed by a 10-year standard usage warranty. What is a heavy duty office chair? 

1. Backrest angle adjustment

The free-float mechanism on the Heathrow 24/7 allows you to independently adjust the angle of the backrest to suit your specific working position. The backrest can be locked in any position, or alternatively left in an unlocked or “free-floating” position where it will follow the movement of your back. 


The Heathrow 24/7 features a non-adjustable lumbar support designed to cater to the needs of most users. If you need specialised lumbar support, it is advisable to complete a sit-test on the Heathrow to assess the compatibility of the fixed lumbar support with your back. Visit our showroom to conduct a sit-test on the Heathrow.

2. Seat adjustment

a. Seat angle adjustment

The mechanism on the Heathrow enables you to adjust the seat angle and lock it in any desired position. A forward slope of up to 5 degrees is possible, which lowers your knees in relation to your hips, effectively “opening” the pelvis. The opening of the pelvis promotes a more natural curvature of the spine, alleviating pressure on the lumbar discs during sitting. This adjustment significantly reduces the risk of experiencing lower back pain. What actually happens when you sit?

b. Seat depth adjustment

The Heathrow features a seat slider that facilitates precise seat depth adjustments, offering the flexibility to move the seat pan backward or forward, aligning it with the length of your thighs. Attaining a comfortable seated position involves maintaining a 2-3 finger gap between the front seat edge and the back of your knees when your back rests against the chair’s backrest. This not only prevents strain behind the knees but also ensures optimal upper leg and under thigh support, promoting healthy blood circulation.

  • For individuals with longer legs, the seat slider allows for INCREASING the seat depth to maintain proper ergonomic posture. Conversely, those with shorter legs may choose to REDUCE the seat depth to avoid perching on the front edge, which can lead to inadequate back support. Excessive seat depth can be particularly problematic for individuals with shorter legs.
  • In situations where coccyx-related issues are a concern, a chair equipped with seat depth adjustment proves invaluable. This customisation capability enables you to tailor the seat depth to alleviate pressure on the coccyx, contributing to enhanced comfort and overall wellbeing.

3. Armrest adjustment

The armrests on the Heathrow 24/7 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 Heathrow has a Free-Float mechanism that promotes Dynamic Sitting.

Dynamic 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.

An Orthopedic Chair is recommended for anyone who has chronic lower back pain. An orthopedic chair must have a forward-tilting seat function that reduces the rotation of the pelvis when sitting down. This decreases the disc pressure in the lumbar region of the back while you are seated. Compared to an ergonomic chair, an orthopedic chair has additional features to ensure the chair can be adjusted to specifically address chronic lower back pain. What is an orthopedic chair?
