Admin October 11, 2026

If you want to choose a widen-support office chair, you can consider the Sihoo M105, the Widen and Enlarge Office Chair (Taobao recommended model), and the Hbada P1 ergonomic chair. Here are the specific introductions:

Sihoo M105: This office chair focuses on cost-effectiveness and performs excellently in terms of widen support. It features a comprehensive enlarged and widened design. Its lumbar pillow is not only wider and larger but also adopts a 220-degree wrap-around design. This unique design can better fit the curve of the human waist, providing all-around support for the waist and effectively reducing waist pressure. Even after sitting for a long day of office work, you won't feel overly fatigued. In addition, its tall and large backrest design is very considerate, able to meet the needs of people of different heights and builds. No matter what the user's body shape is, they can find a comfortable sitting position.

Widen and Enlarge Office Chair (Taobao recommended model): This office chair applies ergonomic design concepts. The backrest has been widened and thickened to perfectly fit the waist curve, providing good support for the waist and reducing the soreness caused by maintaining the same posture for a long time. The seat has also been widened to provide enough space for the legs, preventing poor blood circulation and leg numbness due to limited leg space. It is also equipped with adjustable armrests and a headrest, allowing users to make flexible adjustments according to their height and sitting posture to achieve the best comfort level. The backrest and seat are filled with high-density sponge, which is soft, comfortable, and breathable. The seat surface is made of high-quality PU leather, which feels delicate, is easy to clean, and has waterproof properties. Its price range is between 300 yuan and 800 yuan, offering good cost-effectiveness.

Hbada P1 ergonomic chair: Although it doesn't explicitly mention widening, it has excellent support and comfortable fitting features. Its lumbar support allows for 4.5 cm of up-and-down adjustment and 45-degree rotation, enabling it to precisely fit the lumbar curves of different people and provide personalized support for the waist. The seat cushion is made of high-density native sponge, with a moderately soft and hard sitting feel. It won't easily collapse even after sitting for a long time, ensuring long-term comfort. In addition, it supports a large-angle recline of up to 145 degrees. It also has features such as an adjustable and rotating lumbar support, a 2D adjustable soft-pack headrest, and a curved ergonomic seat cushion, further enhancing the comfort and support during use.
