Why are ergonomic chairs more comfortable to sit in?

Ergonomic chairs, from their research and design to their materials and adjustability, are more ergonomically designed, thus making them more comfortable.

I categorize the benefits of ergonomic chairs into the following three points:

1. More rational weight support, distributing body pressure.

2. Maintaining correct posture, thus promoting health.

3. Improving the coordination of the human-desk-chair system, thereby increasing work efficiency.

In practical experience, the most significant health impact of ergonomic chairs is their support for various parts of the body. The core support of ergonomic chairs is provided to the lower back and hips, which are the two areas most prone to problems from prolonged sitting.

For lumbar support, the core of an ergonomic chair is providing healthy support. The human spine has a natural physiological curvature:

A proper ergonomic chair should have a curved backrest design. However, most office chairs lack this curvature and therefore do not provide adequate support. Prolonged sitting in an office chair can easily lead to hunchback, lumbar muscle strain, herniated discs, and cervical spondylosis. The appropriate support provided by an ergonomic chair can effectively prevent these problems.

Besides spinal support, the most noticeable difference is the increased comfort. With ordinary chairs, all the pressure is concentrated on the ischial tuberosities, leading to buttock pain after sitting for even a short time.

Sitting in such chairs for extended periods can cause the buttock pain I mentioned earlier, and then you might consciously adopt a twisted posture, alternating the pressure between your left and right buttocks. Over time, this can potentially lead to scoliosis.

Ergonomic chairs, on the other hand, typically have a pressure-distributing design, ensuring that no single area bears significant weight, thus evenly distributing the pressure. This makes sitting in an ergonomic chair more comfortable.

Furthermore, even with an ergonomic design, it's difficult to maintain one sitting posture for more than 10 minutes because blood circulation is crucial. We change our posture every 8-10 minutes (I change every 3 minutes) to maintain blood flow and reduce fatigue.

Therefore, the self-adjusting nature of an ergonomic chair is very important. You need to let the chair adapt to you, not the other way around.

What constitutes a healthy office sitting posture?

From a chair perspective, maintaining this healthy posture requires height adjustment, reclining adjustment, armrest adjustment, backrest and lumbar support adjustment, headrest adjustment, and more. It also requires a specifically designed chair, and ergonomic chairs are designed to address this issue. I believe this improves quality of life, rather than being a "rip-off."

Therefore, if you frequently sit for long periods and want to sit comfortably, you should definitely consider an ergonomic chair.

To be more specific:

The headrest adjustment on ergonomic chairs is quite flexible, allowing it to be adjusted below the top of the backrest, with the headrest's convex surface almost flush with the top of the backrest. This level of adjustment should provide a very comfortable experience for people taller than 158cm.

Furthermore, the lumbar support has been upgraded to a dynamic balance tracking backrest, making it more convenient and flexible for office use, eliminating the need for manual adjustments.

The armrest adjustment has also moved beyond one-dimensional adjustment, offering three-dimensional adjustment: up/down, forward/backward, and rotation. The seat cushion also features adjustable depth.

In terms of safety, it uses a level 4 gas spring, a feature typically found only in mid-to-high-end models, outperforming other brands in the same price range.

The only drawback is the use of nylon legs, but this doesn't significantly impact its overall excellent performance. I still believe it's one of the most worthwhile ergonomic chairs in this price range.

Regarding the core lumbar support, the ergonomic chair features a dual-backrest separation structure with an adaptive lumbar support. However, there are two spring plates on each side, resulting in more robust and supportive lumbar support. Even when sitting upright at a desk with a forward lean, the lumbar support still reaches the sacrum, providing very healthy and comfortable support.

The ergonomic chair also supports a maximum recline of 136°, allowing for a more relaxed and comfortable rest during lunch breaks. The headrest is a 2D soft-padded headrest with a wide range of adjustments, especially the 60° swivel, which is superior to similar chairs and provides better support for the cervical spine.

The armrests are 3D adjustable, supporting 7cm height adjustment, 5cm forward/backward adjustment, and 35° swivel adjustment, providing good elbow support for both working and relaxing.

It's worth noting that the entry-level ergonomic chair also features a seat depth adjustment function, allowing for a 5cm adjustment. In addition, the mesh fabric is on the firmer side, and the seat cushion has an anti-leg-trapping design, making it suitable for heavier people.
