Office Chair Reshaping

If referring to the reshaping and repair of office chairs, follow these steps:

1. Check the condition of the wheels:
   Place the chair upright and upside down to observe whether the wheels make even contact with the ground. If the ground is level but the chair is tilted, check each wheel foot for damage or deformation signs while the chair is upside down. If the wheels are damaged, purchase new wheels that match the original model to ensure consistent load-bearing capacity and size.

2. Inspect the seat panel structure:
   If the wheels are in good condition, further inspect the seat panel. Place the chair on its side and locate the metal seat panel (usually a square, black-painted steel plate at the bottom of the seat). If the seat panel is deformed or broken, contact a professional repair technician for replacement to avoid structural instability caused by self-repair.

3. Remove and lubricate the casters:
   To remove the casters, pull them out directly by hand; if they cannot be pulled, use a flat-head screwdriver to assist in prying. For a very small number of casters fixed with screws, use a screwdriver to loosen the screws before removal. Apply a small amount of spray lubricant (such as WD-40) to each chair base socket. If no lubricant is available, apply a pea-sized amount of petroleum jelly to the wheel axles to reduce friction and prevent jamming.

4. Reinstall the casters:
   Use a rubber mallet to tap the casters into the sockets, ensuring the wheel rods are aligned with the base. First, gently push by hand to confirm they are in place; if not fully secured, gently tap with a rubber mallet again, avoiding the use of a metal hammer to prevent damage to plastic components. After installation, place the chair upside down and test whether the wheels rotate smoothly.

5. Final testing and adjustment:
   If the chair is still tilted, repeatedly check whether the seat panel is damaged or contact the manufacturer to confirm whether it is a base structure issue. If the wheels do not rotate flexibly after installation, it may be due to insufficient lubrication or socket deformation, requiring re-treatment.

If referring to the selection of office chairs for plastic surgery hospitals and similar settings:

Office chairs suitable for plastic surgery hospitals need to meet requirements such as strong load-bearing capacity, easy cleaning, and diverse functions. For example, the diagnostic chair and lifting chair from Pinyuan Office Furniture are made of sponge and metal materials and are equipped with casters, footrests, and lifting and rotating functions, facilitating doctor movement and operation. In addition, platforms like Alibaba offer a variety of chairs specifically designed for aesthetic medicine settings, such as the dental doctor chairs and beauty and manicure stools from Foshan Honggang Furniture Co., Ltd. These chairs feature ergonomic designs and support a saddle-shaped sitting posture to alleviate fatigue from long working hours. When selecting, pay attention to whether the materials are stain-resistant and easy to disinfect, as well as whether they comply with safety standards for medical settings.
