Office Chair Seat Cushion Replacement

The replacement of office chair seat cushions requires corresponding methods based on different types of chairs. Here are the detailed introductions:

Replacing the Seat Cushion of a Computer Chair by Yourself

First, measure the size of the mounting holes. This is crucial for ensuring the accurate installation of the new cushion. Then, flip the chair over and place it on a sturdy stool for subsequent operations. Use an Allen wrench to unscrew the screws that fix the base and armrests, and then carefully remove the old cushion. After that, purchase a suitable new cushion online. When you receive it, place it on the stool, put the chair base on the cushion, align the screw holes carefully, tighten the screws, and finally install the armrests and adjust the tightness of the screws to ensure the chair is stable and comfortable to use.

Replacing the Seat Cushion of a Sihoo M18 Chair

First, contact the official store's customer service to purchase a cushion (priced at 60 yuan per piece). The customer service will provide a link for a one-yuan postage supplement. After receiving the goods, you will get a full set of screws (including those for the backrest and armrests) except for the cushion and a standard T-shaped Allen wrench. When starting the replacement, first remove the old cushion. When removing the armrests, note that the screws from five years ago may be rusty and difficult to remove. After removal, clean the dusty corners to keep the chair clean. When installing the new cushion, pay attention to the front and back orientation of the armrests. Connect the armrests to the new cushion, lay the chair down, install the four screws of the cushion, and then replace the three large screws of the backrest. The new version of the Sihoo M18 has unified the diameters of all screw heads, so only the standard Allen wrench is needed to complete the operation.

Reinstalling Soft Cushions on Dining Chairs

• Method 1: First, unscrew the seat of the dining chair from the base. Use a screwdriver to turn it to the left to loosen the screws and store them properly. Use the back of a hammer or a multi-purpose redecoration tool. Insert the end of the tool under the thumbtacks or staples and pull them up to remove them and loosen the fabric. Remove the fabric and padding. If you plan to replace the seat padding, also lift it off the seat. For the filling of older chairs, you can use foam as a replacement. Check the seat base. If it is damaged or weakened, purchase a replacement seat base or cut a multi-layer board according to the size. Use a staple gun to fix it on the new foam and upholstery. To get the size, place the old seat on the multi-layer board, draw a line along the edge, and then cut it with a handsaw.
• Method 2: Cut a piece of dust cover fabric according to the size of the seat and place it on the seat base to cut around the edges. Place the dust cover on the seat base and fix it around the edges with staples to ensure the fabric is taut. Cut a foam pad with a thickness of 2 inches (5.1 cm) according to the size of the seat. Place the seat frame on the foam, use a pen or marker to draw an outline around it, and then use a serrated knife or an electric knife to cut along the outline. Subsequently, combine and fix the foam pad, seat, and cushion cover, paying attention to the cutting and fixing details of the filling.
