Office Chair with Wide Backrest

The following two office chairs feature wide backrests, suitable for users with high demands for back support:

1. Qingxian Maxis Pro This model is specifically designed for heavy-weight users, with overall dimensions significantly larger than regular ergonomic chairs. Its backrest, seat cushion, neck pillow, and armrests all feature a widened design, forming an integrated wide support structure. Key advantages include:

• Structural Safety: Certified by BIFMA X5.11, it can withstand an impact force of 113 kg and repeated impacts of 159 kg, ensuring long-term stability.
• Reclining Function: Equipped with a segmented support system, it supports a 160-degree large-angle reclining position, suitable for lunch breaks or deep relaxation scenarios.
• Comfort Optimization: The zoned sponge filling fits the body's curves, and the air-suction and heat-dissipation function reduces the stuffy feeling from prolonged sitting, especially suitable for summer or high-temperature environments.

2. ENOVA Alloy Master (Standard Edition) Featuring a full aluminum alloy back frame, it stands out for its structural stability, suitable for users requiring strong support. Its design highlights include:

• Material and Adjustment: The back frame is made of aerospace-grade aluminum alloy, paired with an Italian DONATI base, supporting 7-level adjustment of reclining resistance, allowing users to customize support intensity based on their weight or usage habits.
• Dynamic Lumbar Support: Through adaptive adjustment of the lumbar support, it reduces the displacement of the waist during posture changes, alleviating fatigue from prolonged sitting.
• Size Adaptability: Although the specific width is not explicitly marked, the full aluminum alloy back frame design usually reserves a larger support area, suitable for users with a wider body type or those seeking a sense of back enclosure.

Additional Notes: Regular-sized office chairs (such as some products in search results) usually do not emphasize backrest width and may not meet the special needs of users requiring back support. When purchasing, it is recommended to prioritize product parameters such as 'back frame material', 'reclining angle', and 'load-bearing test' to determine if they meet the core needs of a wide backrest. For further comparison of details (such as neck pillow height, armrest adjustment range, etc.), targeted screening can be conducted based on specific usage scenarios (such as office, gaming, or home use).
