Office Chair Seat Cushion Replacement

The seat cushion of an office chair can be replaced by yourself, or you can refer to the replacement method for specific models (such as the Sihoo M18), as detailed below:

Self-Replacement

1. Measurement and Preparation: Measure the size of the mounting holes, find a stool, and flip the chair that needs a new seat cushion over and place it on the stool for easier subsequent operations.
2. Removing the Old Seat Cushion: Find a hex wrench, unscrew the four screws securing the base, and then unscrew the screws on the armrests. This will allow the seat cushion to be removed. During the disassembly process, be sure to keep the screws safe to avoid losing them.
3. Purchasing a New Seat Cushion: Based on the measured size, purchase a suitable seat cushion online.
4. Installing the New Seat Cushion: Place the new seat cushion on the stool, place the chair base on the seat cushion, align the screw holes, and screw in the four screws. During the screwing process, adjust slowly and patiently to ensure the seat cushion is firmly installed and in the correct position.
5. Installing the Armrests: Install the two armrests and adjust the tightness of the screws so that the armrests are neither loose nor too tight, affecting comfort during use.

Taking the Sihoo M18 as an Example

1. Purchasing the Seat Cushion: Contact the official store's customer service to purchase the seat cushion. The customer service will provide a link for a "one-yuan postage supplement," and you can place the order for the corresponding quantity as required.
2. Receiving the Goods: After receiving the goods, in addition to the seat cushion, there will be a full set of screws (including screws for the backrest and armrests) and a standard T-shaped hex wrench.
3. Removing the Old Seat Cushion: First, remove the armrests. For screws that may have rusted from five years ago, the T-shaped wrench will be more useful. After removal, you can take the opportunity to clean the dusty corners before installing the new seat cushion.
4. Installing the New Seat Cushion: Place the new seat cushion in the appropriate position, noting that the armrests have a front and back orientation, and connect the armrests to the new seat cushion. Then, lay the chair down, install the four screws for the seat cushion, and then replace the three large screws for the backrest. The new version has standardized the sizes of all screw heads, so only the standard hex wrench provided is needed to complete the installation.
