Ergonomic chair size plays an important role in ensuring compatibility with the user's body, helping to maintain correct sitting posture, and minimizing health problems such as back pain or neck and shoulder fatigue. In the article below, Okamura will introduce 11+ of the most popular ergonomic chair sizes today, helping you easily choose the right product for your needs. Let's explore now!
1. Basic dimensions of ergonomic chairs
When choosing an ergonomic chair, you should pay attention to factors such as width, depth, seat height, and overall height of the chair. These are key parameters to help you ensure comfort and suitability during use.
1 - Seat width (W)
Seat width is determined by measuring from the left edge to the right edge of the seat cushion, including the armrest (if any). This is an important factor, directly affecting the user's comfort when sitting. If the chair is too narrow, you may feel cramped and uncomfortable while sitting. On the contrary, a chair that is too wide will make it difficult for you to maintain a stable posture, and will make using the armrest inconvenient.
2 - Seat depth (D)
The distance from the seat cushion's front edge to the backrest determines seat depth. This is an important parameter, significantly affecting the ability to support the lower back and comfort when sitting for long periods. If the seat depth is too large, you may feel unbalanced because your thighs are not adequately supported. On the contrary, a chair with too little depth will not provide enough space to rest the thighs, leading to a feeling of fatigue and discomfort. A suitable depth will help distribute body weight evenly, reducing pressure on the lower back and thighs providing optimal comfort.
3 - Overall seat height (OH)
The chair's overall height is calculated from the floor to the highest point of the backrest or headrest (if any). A suitable height makes the chair easy to adjust, ensuring compatibility with the height of the desk and the user's body. This assists the user in maintaining a good sitting posture, allowing the arms to rest comfortably on the table without causing muscle strain. At the same time, the feet can be entirely placed on the floor, reducing pressure on the thighs and providing optimal comfort, improving working efficiency.
4 - Seat height (SH)
Seat height, measured from the floor to the top surface of the seat cushion, plays an essential role in ensuring posture and comfort when using an ergonomic chair:
When the height is adjusted properly, users can keep their knees at a 90-degree angle while placing their feet flat on the floor. This helps reduce pressure on the lower back, support the spine, and maintain a comfortable sitting position throughout work.
On the contrary, if the chair is too high, the thighs will stretch, or the legs will stretch out, causing an uncomfortable feeling. Sitting on a chair that is too low can easily cause the body to bend forward, leading to back pain and fatigue after long work periods.

3. Can the ergonomic chair size be adjusted?
Depending on each product line and brand, ergonomic chair sizes can often be flexibly adjusted. In particular, with high-end ergonomic chair models, users can easily customize the following parameters to suit their body and sitting posture:
Seat Width: Seat width size can be flexibly adjusted thanks to the innovative chair arm system, which can be used for 1D to 4D. 4D armrests allow for diverse customization in four directions: height adjustment (up - down), width (in and out), depth (forward - backward), and tilt angle (rotation). Thanks to that, the chair easily supports the most comfortable and standard hand position, providing an optimal working experience all day.
Seat cushion height: Users can easily adjust the seat cushion height via a lever usually located under the chair or on the right arm. To achieve a standard sitting posture, you should adapt your thighs to parallel the floor and your feet firmly touch the ground. This helps to reduce pressure on the spine and supports a comfortable, stable sitting posture.
Seat depth: Users can adjust the seat depth via the switch on the left side of the seat cushion, which is conveniently designed for easy operation even while sitting. The depth adjustment optimizes support for the lower back while reducing pressure on the thighs, providing comfort, and helping maintain correct sitting posture.
Ergonomic chair size improves user comfort, supports health, and enhances work efficiency. Choosing the right chair model for your body shape helps you maintain the correct sitting posture and limits spinal problems.
