Mechanism on the Heathrow Heavy Duty Orthopedic Office Chair
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?

Very good and professionalPosted on Busenati Mwati11/03/2026Trustindex verifies that the original source of the review is Google. I was a bit hesitant to buy an office chair online without trying it first, but my experience with Karo has completely exceeded my expectations. I received my OrthoMax Orthopedic Chair just over a week ago, and honestly, it's been a game-changer for my posture and comfort. However, what really made this a 10/10 experience was the process. The website made purchasing easy, and true to their word, the chair arrived fully assembled — no struggling with screws and manuals! I also had a few specific questions before buying, so I reached out via WhatsApp. Their sales support was absolutely brilliant; they addressed every query thoroughly and made me feel confident in my choice. I couldn't be any happier with my purchase. If you're on the fence, go for it. Amazing product and top-tier service.Posted on Yolandi Rabie11/03/2026Trustindex verifies that the original source of the review is Google. Would Really recommend Karo. The desk was delivered quickly and effortlessly. The desk is really good quality and I enjoy it’s pre set settings.Posted on Yushir Maharaj10/03/2026Trustindex verifies that the original source of the review is Google. I recently bought the Fenix Ergonomic Office Chair and I’m very happy with it. After using it for daily work at my desk, it’s been comfortable from day one and works great for long hours. The adjustable lumbar support and armrests make a big difference, and the mesh back feels strong and supportive when leaning back. Delivery was smooth and easy and the chair arrived fully assembled, so it was just a matter of removing the packaging and using it right away. Instructions were clear and included a helpful YouTube guide for the adjustments. Customer service was excellent and communication throughout the process was clear and professional. Overall a great chair and a great buying experience from Karo. Highly recommended.Posted on Kim van Schoor09/03/2026Trustindex verifies that the original source of the review is Google.

Will definitely be recommending Karo and lelia chair in the future.
