Office Chair with Hollow-Out Armrests

The following three office chairs feature hollow-out designs and explicitly mention armrest-related characteristics:

1. Jingyu M-7pro Ergonomic Chair
The space gray model of this chair features a hollow-out cushion design aimed at enhancing breathability and reducing heat buildup during prolonged sitting. Its armrests offer 9D adjustment, supporting multi-dimensional adjustments such as up/down, front/back, left/right, and rotation, catering to different heights and sitting postures. The combination of the hollow-out cushion and adjustable armrests provides both breathability and ergonomic support, making it suitable for users who need to work for extended periods.

2. Sihoo G03 White Hollow-Out Office Chair
This model focuses on lumbar support and breathable mesh as its core selling points. Both the backrest and cushion are made of hollow-out mesh fabric, improving air circulation efficiency. Its armrests offer 5D adjustment, supporting height, angle, and front/back sliding adjustments, meeting basic support needs. The mesh fabric paired with adjustable armrests makes it suitable for summer or office environments with high ventilation requirements.

3. Jingyu M8Pro Butterfly Wing Ergonomic Chair
The inspiration gray model features a hollow-out cushion inspired by butterfly wings, combining aesthetics with breathability. Its armrests offer 10D adjustment, supporting multi-directional adjustments such as up/down, front/back, left/right, rotation, and tilting, even accommodating arm support in reclined positions. This multi-dimensional adjustability makes it the most flexible armrest option among the three, suitable for users with high demands for personalized support.

Additional Notes:

• No direct combination of “hollow-out armrests” was found in the search results. The above recommendations primarily feature hollow-out cushions, with armrest functionality focusing on adjustability.
• If users have specific needs for armrest breathability, mesh fabric armrests (such as the extended mesh design of the Sihoo G03) can be prioritized. However, note that such designs typically prioritize overall breathability over localized hollow-out features.
• Price information for accessories (such as armrest covers or replacement parts) is not directly related to the hollow-out armrest feature and was not included in the recommendations.

All the above models indirectly meet breathability and support needs through adjustable functions or material selection. Users can further filter based on specific usage scenarios (such as season or sitting habits).
