Firstly, the height of the crutches should be properly adjusted to suit the user's body. This is important not only for comfort but also for maintaining a good posture while walking. The top of the crutch grip should ideally be at the user's wrist level when the arms are relaxed by the sides. This positioning helps to ensure that the user can apply even weight to the crutches without leaning or straining.

Furthermore, the functionality of waiting room chairs cannot be understated. Flexibility is vital in healthcare settings, as the demographic of visitors can vary widely, from young children to elderly patients. Chairs should accommodate different body types and mobility levels. For example, chairs with adjustable seating heights can be beneficial for those who may struggle with mobility. Additionally, having chairs with armrests can provide assistance for individuals who need help when standing up or sitting down.
