145° Reclining Office Chairs

Admin October 09, 2026

Among office chairs with a 145° reclining function, the Xia Mumu Fit and Sihoo C300 are representative models that explicitly support this feature. Although the SumLush Xia Mumu Fit2 does not explicitly state the angle, it stands out for its exceptional lumbar support and typically offers a similar function. Here is a detailed analysis:

Xia Mumu Fit Ergonomic Office Chair
This model features 145° backrest adjustment as its core function, designed with a 'wide-angle golden support' to help the body quickly recover energy during short breaks. Its key advantage lies in the ZeroG Dynamic Lumbar Support System, which achieves dynamic spinal support through an integrated linkage structure, reducing the risk of lumbar spine injury by 98% during prolonged sitting, decreasing lumbar pressure by 140%, while enhancing lumbar muscle support by 130% and fit by 94%. The seat cushion employs six-way rebound cloud-like technology, dispersing hip and thigh pressure through a saddle-shaped curved design, combined with a breathable hollow structure to reduce stuffiness. It also features wear-resistant and antibacterial properties, with no sagging or deformation after standing up, making it suitable for long hours of office work and lunch breaks.

Sihoo C300 Ergonomic Office Chair
As a popular model in the thousand-yuan price range, the Sihoo C300 explicitly supports 145° ultra-wide backrest adjustment with four gears and comes with a retractable footrest. During lunch breaks, users can achieve a near-flat lying position by adjusting the angle and using the footrest, earning it the title of 'king in the thousand-yuan price range'. Its design caters to the need to switch between office and rest scenarios, making it suitable for users with a limited budget but high demands for reclining functionality.

Although it does not explicitly mention a 145° reclining function, as a flagship model of the brand, its lumbar support performance and stability have undergone 26 iterations of optimization, with over 2000 detail improvements, and have been certified by domestic and foreign testing institutions. This model leads in reputation in the high-end market and typically comes with multi-gear backrest adjustment functions. Combined with its lumbar support technology, it can be inferred that its maximum reclining angle is close to or reaches 145°, making it suitable for users with extreme demands for lumbar protection and sufficient budget.
