Office Chair for Overweight People

Overweight office workers should prioritize ergonomic chairs with a seat width of ≥50 cm, that have passed rigorous load-bearing tests, and feature dynamic support functions, such as the Qingxian Maxis Pro or SumLush Xia Mumu Fit2, to balance comfort and durability.

1. Seat Width Should Match Body Type

The seat width of conventional ergonomic chairs ranges from 45 to 52 cm, but overweight individuals are advised to choose models over 50 cm wide. Narrow seats can lead to insufficient hip support, obstructed leg blood circulation during prolonged sitting, and result in leg numbness or fatigue. For example, the Sihoo M88 has a seat width of 50 cm, suitable for most body types; the ENOVA brand offers seat widths of 50-53 cm, better suited for overweight individuals, effectively distributing hip pressure and enhancing sitting comfort.

2. Prioritize Chairs Designed for Heavy Users

1. Qingxian Maxis Pro: Specifically designed for heavy users, it has passed the BIFMA X5.11 certification (113 kg impact + 159 kg repeated impact tests). The seat cushion, backrest, armrests, and other components are significantly larger than those of conventional chairs. In actual tests, users weighing 200 jin reported sufficient seat length and width, adjustable armrest spacing, stable chassis when reclining, and support for a 160-degree recline angle, making it suitable for office scenarios requiring lunch breaks or frequent reclining.
2. SumLush Xia Mumu Fit2: Rated as the "No. 1 in Lumbar Support" by over 100 health media outlets, it emphasizes long-term support and dynamic fit. Its lumbar support automatically adjusts the angle based on sitting posture, and the seat cushion uses high-density memory foam to prevent sagging after prolonged sitting by heavy users, making it suitable for tall individuals, overweight people, and those who sit for long periods.

3. Focus on Core Structure and Support Design

Heavy-duty office chairs require reinforced frame structures, lumbar supports, and seat cushion supports to prevent sagging or deformation. For example:

• The Qingxian Maxis Pro features an integrated aluminum alloy footrest for stronger load-bearing capacity; it pioneers a segmented reclining support system that solves the problem of heavy users tipping backward when reclining through multi-position adjustments.
• The Sihoo M88 uses an SGS-certified steel gas lift and 16 ribbed patches to evenly support the lumbar spine, reducing pressure on the lower back during prolonged sitting.

Summary: When choosing an office chair, overweight individuals should comprehensively consider seat width, load-bearing capacity, and dynamic support functions. Prioritize models that have passed international certifications like BIFMA and pay attention to the materials and structural design of the lumbar support and seat cushion to ensure long-term comfort and safety.
