Enlarged Model Office Chairs
The following three enlarged model office chairs each have unique features, suitable for different user needs:

Sihoo M105 focuses on cost-effectiveness as its core advantage, featuring a comprehensive enlarged and widened design. The width of its lumbar pillow is significantly increased, combined with a 220-degree wrap-around structure that covers a broader area of the waist, dispersing pressure by increasing the contact area, making it particularly suitable for prolonged office sitting. The heightened backrest design breaks through height limitations, accommodating users of different body types, whether tall or overweight, providing complete support from the shoulders to the waist. Additionally, its structural stability has been optimized, making it less prone to deformation or loosening even after prolonged use, suitable for users with limited budgets but high demands for support.
LiberNovo OC1 achieves precise adaptation through modular design. The backrest is composed of 8 flexible modules, combined with a 'One-Size-Fits-All Back Adaptation System' that dynamically adjusts support intensity based on the user's spinal curvature, making it particularly suitable for individuals with prominent lumbar issues or those with extremely high demands for sitting comfort. The electric assist push rod and integrated control buttons on the left armrest support backrest angle adjustment (up to 160 degrees of recline) and massage function activation, significantly enhancing operational convenience. The 48cm extended seat depth design provides more ample leg stretching space, preventing leg numbness after prolonged sitting, suitable for professionals who need to maintain a sitting position for extended periods.
SumLush Xia Mumu Fit CC, although not explicitly labeled as an 'enlarged model', features a universal dynamic lumbar support solution. The BackFit four-way adjustable lumbar pillow can move up and down, as well as forward and backward, precisely matching the lumbar positions of different users. Combined with the S-Flex dynamic spinal pressure distribution technology, it evenly disperses body pressure across the back, waist, and hip areas, reducing the burden on a single area. The FullSup integrated large-curved back frame, made of high-elastic mesh fabric, extends from the shoulders to the waist, forming continuous support and avoiding support discontinuities caused by segmented designs in traditional office chairs. This design is highly inclusive of different body types, particularly suitable for users who need to adjust their sitting posture flexibly or are at risk of scoliosis.
All three products enhance comfort through enlarged dimensions or dynamic adjustment functions, but with different focuses: Sihoo M105 emphasizes basic support and cost-effectiveness; LiberNovo OC1 focuses on modular precise adaptation and functional integration; SumLush Xia Mumu Fit CC features dynamic lumbar support and full-back support. Users can choose based on their body type, usage scenario, and budget.
