I. Characteristics related to materials Carbon steel material High strength and stability Carbon steel has relatively high strength and can provide a stable frame structure for the commode chair. This makes the commode chair not easily deformed or damaged when bearing the user's weight. Even people with heavier weights can use it safely and reliably. For example, when the user stands up or sits down, they may exert greater pressure on the commode chair. The high strength of carbon steel can handle this pressure well and ensure the overall stability of the commode chair. Durability Carbon steel is a relatively durable material. It has good wear resistance. In daily use, even if the commode chair is frequently moved or has slight friction with other objects, it is not easy to show wear. At the same time, carbon steel also has relatively good corrosion resistance. Although it may not be as good as stainless steel, in a normal indoor use environment, through appropriate surface treatment (such as painting), it can effectively prevent rust and extend the service life of the commode chair. II. Characteristics of round hole design Ventilation The round hole design on the seat surface helps with air circulation. For users, especially those who need to sit on the commode chair for a long time (such as the elderly or those with physical disabilities), good ventilation can reduce stuffiness and improve comfort. For example, in summer or when the indoor temperature is relatively high, the round hole can allow air to circulate better around the user's buttocks and avoid discomfort caused by excessive sweating. Drainage (if used in a humid environment) If the commode chair is used in a humid environment such as a bathroom, the round hole design is beneficial for drainage. When there is accumulated water on the surface of the commode chair (such as when bath water splashes on it), the water can be quickly drained through the round hole to prevent the slippery surface caused by accumulated water, reduce the risk of users slipping, and at the same time help keep the commode chair dry and reduce bacterial growth. III. Characteristics of adjustable height Widespread applicability The height-adjustable function enables the commode chair to adapt to users of different heights. Whether it is a short child (under special care needs), an adult of average height, or a tall person, they can adjust the commode chair to a suitable height according to their own situation. The appropriate height helps the user's feet land steadily, making the actions of standing up and sitting down easier and reducing the burden on the legs and waist. Personalization and flexibility In a family or caregiving environment, different users may have different height requirements for the commode chair. The height-adjustable commode chair can be personalized according to personal preferences and actual physical conditions. For example, for people with leg injuries, they may need to adjust the commode chair to a slightly higher position to better avoid leg stress; while for users with relatively flexible movements, they may prefer a lower setting that is closer to the height of an ordinary seat to obtain better stability. In addition, in the case of multiple people sharing the commode chair, the height-adjustable function increases the flexibility and versatility of the commode chair.
