Homemade Modified Office Chair
There are mainly three ways to homemade modify office chairs: homemade base reinforcement, homemade dual-drive convertible, and homemade simple ergonomic chair.
Homemade Base-Reinforced Office Chair: This method is mainly aimed at situations where the office chair is damaged due to the weight of a heavy person. When the office chair has issues such as an unstable base due to bearing a large weight, making a homemade base can effectively solve the problem. During the specific operation, it is necessary to select appropriate materials to make the base according to the actual situation of the chair, such as sturdy metal sheets or high-strength plastic sheets. During the production process, ensure that the size of the base matches the chair and can closely fit the bottom structure of the chair. When installing, use appropriate connectors, such as screws and bolts, to firmly fix the homemade base to the chair, thereby enhancing the overall stability of the chair, enabling it to bear a greater weight and extending its service life.
Homemade Dual-Drive Convertible Office Chair: This is a relatively complex and creative modification method. First, prepare an office chair and deliberately break it by sitting on it, then take it home. Next, remove the chair base and measure the fixed distance between the bolt holes, which is an important basis for the subsequent production of the base frame support. Then, cut square steel to make the base frame support and weld it into shape, while drilling appropriate screw holes. After that, cut circular steel pipes and weld them onto the central shaft, performing operations such as sealing, drilling holes, and welding the other end. Then, cut rectangular steel pipes to make the chassis, weld it into a shape similar to the letter 'C' and drill holes, and assemble it with the support using threaded rods. Prepare wheels and install transmission gears, fix them on the chassis with short screws and weld the wheels. Weld a T-shape and extend it to the front of the chassis, and weld universal wheels at the contact surface of the chassis with the ground. Connect the shock absorbers, weld motor mounts with steel pipes, install two motors, make a battery compartment and install the battery. Finally, use disposable food containers to install the circuit control board and motor speed switch, weld brackets to fix the containers on both sides of the armrests, and connect all the wires. The entire process requires certain skills in welding, machining, and circuit installation.
Homemade Simple Ergonomic Chair: This method is relatively simple and mainly uses a few ready-made small items to improve the office environment. For example, use a lumbar support pillow and place it between the chair backrest and the waist to provide good support for the waist, reduce waist pressure, and relieve fatigue caused by prolonged sitting. You can also use some adjustable footrests to adjust the height of the footrests according to your height and sitting posture, keeping your legs in a comfortable position and promoting blood circulation.
