The ergonomic design of these trays seeks to minimize physical strain on healthcare workers. Many models have adjustable heights, which can be crucial in preventing injuries related to lifting and bending. Additionally, the trays are often constructed with materials that are easy to clean and disinfect, promoting hygiene and safety in environments where contamination risks are significant.

Walker chairs are generally equipped with features designed to enhance user safety, such as non-slip feet and brakes. These features help to ensure that the chair remains stable when in use, reducing the risk of accidents. Moreover, the adjustable height of many walker chairs allows for a customized fit, ensuring that users can comfortably navigate their surroundings without straining their bodies.
