Office Chair Unboxing Guide

Unboxing an office chair should follow three steps: 'inspection - installation - adjustment', with a focus on verifying core components. Here's a detailed guide:

I. Pre-unboxing Inspection: Verify Accessories and Core Component Specifications

1. Check the Accessory List: According to the instruction manual, check one by one to ensure all accessories are present, including the back frame, seat cushion, headrest, armrests, five-star base, gas lift, and wheels. Different brands may have variations in accessories; for example, the Sihoo C300 Pro 2nd generation requires distinguishing between M6 and M8 short screws, while the Henglin Nixizhe armrests have a fixed height but can be folded upwards for storage. Confirm these details in advance.
2. Inspect Core Components: Focus on the gas lift, base, and wheels. Verify that the gas lift is a Class 4 specification (as with the Sihoo C300 Pro 2nd generation) and check for safety certification marks such as SGS. The base should be checked to see if it features a brand-exclusive design (like Sihoo's 'Space Base'). For the wheels, confirm whether they have a wrapped, silent design (like Sihoo's) or are smooth and noise-free (like Henglin's) to reduce the risk of scratching the floor.

II. Installation Process: Follow the Sequence and Prioritize Heavy Components

1. Refer to the Instruction Manual or Video: Read the instruction manual first; if the operation is complex, combine it with a video demonstration (such as the immersive unboxing video for the Xiamumu Fit CC). Different brands may have different installation sequences; for example, the Sihoo C300 Pro 2nd generation recommends connecting the seat cushion and backrest first, then installing the footrest, armrests, and five-star base. The Henglin Nixizhe has a simpler assembly process and can be installed step by step according to the accessory sequence.
2. Prioritize Heavy Components: When installing, first secure heavier components like the seat cushion and back frame, then install lighter accessories such as the armrests and headrest. Screws should be distinguished by specification to avoid misuse (e.g., the M6 and M8 short screws for the Sihoo C300 Pro 2nd generation should correspond to the correct holes).

III. Adjustment and Detail Optimization: Ensure Comfort and Safety

1. Adjust Recline and Support: After installation, test the recline function to confirm whether the base (like Sihoo's 'Space Base') provides a smooth support experience. Check if the lumbar support (such as the adaptive lumbar support of the Henglin Nixizhe) and headrest can be adjusted to suitable positions.
2. Check Wheels and Stability: Push the chair to confirm that the wheels move smoothly without jamming and that the five-star base (such as Henglin's aluminum alloy base) is stable. If the wheels are noisy or leave scratches on the floor, check if the wrapped design is properly implemented.
3. Breathability and Storage Function: Confirm that the seat mesh (such as the breathable mesh of the Henglin Nixizhe) is thick and undamaged, and whether the armrests can be folded upwards (like Henglin's) to save space.

Tip: Keep the packaging box for at least one week after unboxing for returns or exchanges. If you encounter issues such as mismatched screws or damaged components during installation, contact the brand's customer service promptly.
