Office Chair Armrest Modification

There are mainly several ways to modify office chair armrests, including replacing adjustable armrests and silent wheels, giving ordinary armrests a solid wood chair texture, and making self-made horn-shaped armrests.

Replacing Adjustable Armrests and Silent Wheels

If the wheels of an old ergonomic chair are stiff or the armrests are uncomfortable, you can purchase replacement parts for replacement. For wheels, silent wheels are a good choice, with an average price of 15 yuan and easy installation. Simply pull off the original wheels and replace them with new silent wheels. These wheels have strong load-bearing capacity and smooth rotation, effectively improving the user experience. If the armrest size is not suitable, you can modify the hole positions for installation. The whole process is time-saving and cost-effective, suitable for users who pursue cost-effectiveness and have low requirements for modification difficulty.

Giving Ordinary Armrests a Solid Wood Chair Texture

• Tools and Materials: You need to prepare rosewood offcuts, a coping saw (or handsaw), a hand plane, sandpaper, a screwdriver, a utility knife, a pencil, wood wax oil (or paint), wood glue, etc.
• Production Steps: First, disassemble the armrests. Be careful when removing the armrest surface to avoid damaging the armrest surface support plate. Then, use thick cardboard to draw the thickness contour of the old armrest surface and cut out the pattern. Place the pattern on a small square piece of wood and draw the contour. Next, cut out the wood along the contour, apply glue on the side, and clamp it tightly with woodworking clamps. After 24 hours when the glue is dry, remove the clamps. Then, plane the back of the assembled armrest surface flat with a small hand plane, sand the bottom flat with coarse sandpaper, and then draw the size contour with the old armrest surface and saw out the shape. Finally, you can apply wood wax oil or paint for coloring according to personal preference to give the armrest a better texture. This method is suitable for users who like the solid wood texture and have certain hands-on skills.

Making Self-made Horn-shaped Armrests

• Required Materials: 18 stainless steel nuts, 4 stainless steel inner hexagon bolts, and a small cow M handle (can be purchased on Xianyu, with a price range of 50 - 80 yuan).
• Required Tools: 1 electric hand drill and pointed tools (cross-head screwdrivers, positioning pins, long thin nails, long thin drill bits, etc.).
• Difficulty Solutions: First, fix the front hole positions. Rotate around this hole position as the center, use pointed tools to pass through the existing screw holes on the seat iron plate from top to bottom, and mark the positions on the handle. Finally, drill holes according to these marked points. The hole diameter should be slightly smaller than the head of the inner hexagon bolt, and do not cut the handle. Just drill holes according to the tutorial pictures. This method is suitable for users who pursue unique shapes and have strong hands-on skills.
